[SOLVED] USB installation, booting: root fs cannot be detected

I followed this guide: http://wiki.archlinux.org/index.php/Ins … _a_USB_key
SYMPTOMS
I installed arch linux on a USB stick.
I can see Grub, I can boot. After the HOOKS get loaded (udev is loaded as well: Loading udev...done.) I get errors as follows:
Attempting to create root device '/dev/disk/by-uuid/myHdUUID'
unknown
ERROR: root fs cannot be detected. Try using rootfstype= kernel parameter.
If the device '/dev/disk/by-uuid/myHdUUID' gets created while you are here, try adding 'rootdelay=8' or higher to the kernel command-line...
Then I get a prompt that doesn't even let me issue the command "ls" (error: /bin/bash: ls: not found
SOLUTION: use the fallback image, or better, rebuild your mkinitcpio kernel image, see: Configuring mkinitcpio
My problem was that "usb" was not included in the HOOKS, it was present, yes but after the "autodetect".
So, in the /etc/mkinitcpio.conf place "usb" before "autodetect", e.g. as follows:
HOOKS="base udev autodetect sata filesystems"
then regenerate the image (refer to the previous link to understand why the autodetect was creating the problems and to see exactly how to regenerate the image)

Same problem, seems the new kernel broke UUID.
@tim: as I stated above it seems that you fixed the problem with the kernel image file but did not adjust the grub menu to compensate for the fact that UUID is broken and thats why you got the same result even after fixing the image, lucky for me I had some broken hooks and only my fallback image generated properly so I figured it out, although it took me a little while.
Anyhow this is basically what needs to be done to correct the problem.
1. Boot ArchLive
2. mkdir /media/disk
3. mount /dev/sdxX /media/disk
4. chroot /media/disk
5. mkinitcpio -k 2.6.28-ARCH -g /boot/kernel26.img
6. nano /boot/grub/menu.lst
7. Replace any references to UUID with /dev/sdxX (where xX represents your drive and partition) instead, save and exit nano.
8. reboot
Make sure and pay attention to the output of the mkinitcpio command in my step 5. If there are any errors relating to one or more of the hooks you'll need to edit /etc/mkinitcpio.conf and remove the hook it complains about !!IF POSSIBLE!!. I for example had some problem with the autodetect hook which caused my regular kernel to fail to create an image.
If mkinicpio doesn't complain and tells you it SUCCEEDED generating the images then you should be good to go.

[SOLVED] USB Installation Media Boot Problems

Hi all,
I'm having trouble creating a live USB stick that my new (to me) HP Elitebook
2730p laptop can boot successfully. Here is what I've tried so far:
1. dd with the latest stable Arch installation media
In other words:
# dd if=/path/to/archlinux*.iso of=/dev/sdb
Result: I can boot with the USB stick on my old Dell laptop (which is running
Arch) without issue, but can't with the new HP. The BIOS will freeze if the USB
stick is inserted, and will only unfreeze after I remove it.
2. dd with a recent Arch installation media snapshot
The snapshot is ``archlinux-2012.06.05_04-00-01-core-x86_64.iso''. I
install the image to the USB stick with the same dd method above,
and I get the same behavior: works fine on the old Dell, but freezes the BIOS of
the new HP.
3. dd with an old lubuntu iso
This time, I used an old lubuntu iso
(lubuntu-11.10-desktop-amd64.iso) with dd. This method
worked without a problem -- both my old Dell and my new HP would boot it without
complaint.
3. unetbootin with the latest stable Arch installation media
Creating the USB stick with unetbootin allows me to boot the stick with the new
HP, but the boot fails to the ramfs prompt after ``Waiting 30 seconds for device
/dev/disk/by-label/ ...'' (notice how there's nothing after ``by-label/'').
Adding ``vmalloc=448M'' to the end of the unetbootin boot entry makes no
difference.
4. Image Writer for Windows
The ``USB Installation Media'' wiki page suggests using ``Image Writer for
Windows'' to create a bootable USB stick. I tried this method using Windows 7
Professional, and the result was the same as attempts 1 and 2: the USB stick
freezes the HP's BIOS.
Other notes
I've checked the md5sums of all the isos I've tried
I've updated the BIOS on the HP laptop
I've used the same USB stick for each of the above situations
The new HP laptop does not have an optical drive, and I don't own an
external one
In attempts 1, 2, and 4, I noticed that cfdisk shows that the partition
that contains the installation files has both the ``Bootable'' and ``NC'' flags
set. The cfdisk man page says that the latter flag stands for ``Not Compatible
with DOS or OS/2''. I can actually remove this flag by using the ``Maximize''
option in cfdisk, which actually makes the USB stick bootable by the HP
computer's BIOS, but the boot eventually fails to the ``ramfs prompt
thingy'' after saying ``ERROR: '/dev/disk/by-label/ARCH_201108' found, but the
filesystem type is unknown''
In attempt 3 (the lubuntu one), I noticed that cfdisk shows a bit of free
space in front of the partition that contains the lubuntu files. The ``NC'' flag
is not present when I run cdisk.
My current theory is this: I believe my new HP's BIOS is unhappy with the
``isohybrid-nature'' of the Arch installation media. Is there any way I can
confirm this, or obtain ``non-isohybrid'' Arch media?
As you might imagine, this has been pretty frustrating. Any help would be
greatly appreciated!
Daniel

Duh. That's for booting it from RAM (with MEMDISK) in case it doesn't map the entire file, which for some reason it didn't for the i686 iso on my computer. I probably should've specified it when I wrote the article. I'll add it tomorrow morning.
Speaking of which, have you tried it?
https://wiki.archlinux.org/index.php/US … O_from_RAM
Because you only seem to be using dd ("Image Writer" is the same) and Unetbootin (which had various problems since forever). The correct syntax for dd is:
$ sudo dd if=archlinux.iso of=/dev/sd[x]
Warning: Make sure to use /dev/sdx and NOT /dev/sdx1. This is a very common error!
https://wiki.archlinux.org/index.php/US … _USB_drive
Haven't tried the ``Boot the entire ISO from RAM'' method yet. I'll give that a shot next.
The ``Boot the entire ISO from RAM'' method worked like a charm! Thanks,

[solved]USB wont boot on some computers.

Hi all.
I have installed arch on a usb from a running arch system after doing pacman -S arch-install-scripts.
It boots on my Acer Aspire One which picks it up as a USB-HDD however when I tried to boot it on a different computer it didn't work and faliled with the error "Boot Error".
I have succesfully booted both ubuntu and fedora on the same pc.
Any ideas?
Not able to access my arch system right now but will the fact that arch is installed to a partition (sdb1) and not directly affect it(sdb)?
Previously I used the universal usb installer from pendrivelinux.com with it set to format the drive. I believe it did not use partitions.
I believe I just answered my own question. Anyone mind confirming if I'm correct ?

Some older bioses boot from USB in "floppy mode" (it shows the disk as a floppy if it is not partionned, otherwise the first partition is shown as a floppy, possibly with a limitation of size). If you know your bootloader, you can manage to make it bootable (I think this is much easier with syslinux than with grub, because it can detect at boot time from where it is booted; without having you to explicitly tell it). You can also try the plop boot manager (http://www.plop.at/en/bootmanager/index.html). It is able to boot USB devices in hard disk mode even without Bios support.

[SOLVED] Installing on ZFS root: "ZFS: cannot find bootfs" on boot.

I have been experimenting with ZFS filesystems on external HDDs for some time now to get more comfortable with using ZFS in the hopes of one day reinstalling my system on a ZFS root.
Today, I tried installing a system on an USB external HDD, as my first attempt to install on ZFS (I wanted to try in a safe, disposable environment before I try this on my main system).
My partition configuration (from gdisk):
Command (? for help): p
Disk /dev/sdb: 3907024896 sectors, 1.8 TiB
Logical sector size: 512 bytes
Disk identifier (GUID): 2FAE5B61-CCEF-4E1E-A81F-97C8406A07BB
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 3907024862
Partitions will be aligned on 8-sector boundaries
Total free space is 0 sectors (0 bytes)
Number Start (sector) End (sector) Size Code Name
1 34 2047 1007.0 KiB EF02 BIOS boot partition
2 2048 264191 128.0 MiB 8300 Linux filesystem
3 264192 3902828543 1.8 TiB BF00 Solaris root
4 3902828544 3907024862 2.0 GiB 8300 Linux filesystem
Partition #1 is for grub, obviously. Partition #2 is an ext2 partition that I mount on /boot in the new system. Partition #3 is where I make my ZFS pool.
Partition #4 is an ext4 filesystem containing another minimal Arch system for recovery and setup purposes. GRUB is installed on the other system on partition #4, not in the new ZFS system.
I let grub-mkconfig generate a config file from the system on partition #4 to boot that. Then, I manually edited the generated grub.cfg file to add this menu entry for my ZFS system:
menuentry 'ZFS BOOT' --class arch --class gnu-linux --class gnu --class os {
load_video
set gfxpayload=keep
insmod gzio
insmod part_gpt
insmod ext2
set root='hd0,gpt2'
echo 'Loading Linux core repo kernel ...'
linux /vmlinuz-linux zfs=bootfs zfs_force=1 rw quiet
echo 'Loading initial ramdisk ...'
initrd /initramfs-linux.img
My ZFS configuration:
# zpool list

External2TB/PacmanCache 5.77G 1.77T 5.77G /var/cache/pacman/pkg
External2TB/Swap 8.50G 1.78T 20K -
The reason for the above configuration is that after I get this system to work, I want to install a second system in the same zpool on a different dataset, and have them share a pacman cache.
GRUB "boots" successfully, in that it loads the kernel and the initramfs as expected from the 2nd GPT partition. The problem is that the kernel does not load the ZFS:
ERROR: device '' not found. Skipping fsck.
ZFS: Cannot find bootfs.
ERROR: Failed to mount the real root device.
Bailing out, you are on your own. Good luck.
and I am left in busybox in the initramfs.
What am I doing wrong?
Also, here is my /etc/fstab in the new system:
# External2TB/ArchSystemMain
#External2TB/ArchSystemMain / zfs rw,relatime,xattr 0 0
# External2TB/PacmanCache
#External2TB/PacmanCache /var/cache/pacman/pkg zfs rw,relatime,xattr 0 0

UUID=7a37363e-9adf-4b4c-adfc-621402456c55 none swap defaults 0 0
I also tried to boot using "zfs=External2TB/ArchSystemMain" in the kernel options, since that was the more logical way to approach my intention of having multiple systems on different datasets. It would allow me to simply create separate grub menu entries for each, with different boot datasets in the kernel parameters. I also tried setting the mount points to "legacy" and uncommenting the zfs entries in my fstab above. That didn't work either and produced the same results, and that was why I decided to try to use "bootfs" (and maybe have a script for switching between the systems by changing the ZFS bootfs and mountpoints before reboot, reusing the same grub menuentry).
Thanks in advance for any help.

Sounds like a zpool.cache issue. I'm guessing your zpool.cache inside your arch-chroot is not up to date. So on boot the ZFS hook cannot find the bootfs. At least, that's what I assume the issue is, because of this line:
ERROR: device '' not found. Skipping fsck.
If your zpool.cache was populated, it would spit out something other than an empty string.
Some assumptions:
- You're using the ZFS packages provided by demizer (repository or AUR).
- You're using the Arch Live ISO or some version of it.
On cursory glance your configuration looks good. But verify anyway. Here are the steps you should follow to make sure your zpool.cache is correct and up to date:
Outside arch-chroot:
- Import pools (not using '-R') and verify the mountpoints.
- Make a copy of the /etc/zfs/zpool.cache before you export any pools. Again, make a copy of the /etc/zfs/zpool.cache before you export any pools. The reason for this is once you export a pool the /etc/zfs/zpool.cache gets updated and removes any reference to the exported pool. This is likely the cause of your issue, as you would have an empty zpool.cache.
- Import the pool containing your root filesystem using the '-R' flag, and mount /boot within.
- Make sure to copy your updated zpool.cache to your arch-chroot environment.
Inside arch-chroot:
- Make sure your bootloader is configured properly (i.e. read 'mkinitcpio -H zfs').
- Use the 'udev' hook and not the 'systemd' one in your mkinitcpio.conf. The zfs-utils package does not have a ported hook (as of 0.6.2_3.12.6-1).
- Update your initramfs.
Outside arch-chroot:
- Unmount filesystems.
- Export pools.
- Reboot.
Inside new system:
- Make sure to update the hostid then rebuild your initramfs. Then you can drop the 'zfs_force=1'.
Good luck. I enjoy root on ZFS myself. However, I wouldn't recommend swap on ZFS. Despite what the ZoL tracker says, I still ran into deadlocks on occasion (as of a month ago). However, I cannot say definitely the cause of the issue; but it resolved when I moved swap off ZFS to a dedicated partition.

[SOLVED] UEFI installation - booting failure

Hi All,
Setting in BIOS: UEFI boot mode, Secure Boot Off
Booting from USB in UEFI mode, everything is OK. Then I did this:
gdisk /dev/sda
create new GPT partition
cgdisk /dev/sda
Part. # Size Partition Type Partition Name
1007.0 KiB free space
1 512 Mb EFI system efi
2 6 GiB Linux filesystem root
3 122 GiB Linux filesystem home
mkfs.vfat -F32 -n efi /dev/sda1
mkfs.ext4 /dev/sda2
mkfs.ext4 /dev/sda3
mkdir -p /mnt/boot/efi
mount /dev/sda1 /mnt/boot/efi
mount /dev/sda2 /mnt
mkdir -p /mnt/home
mount /dev/sda3 /mnt/home
Then I followed the installation guide. At the "Install a bootloader" section I tried both EFISTUB and GRUB:.
At Point 5 here https://wiki.archlinux.org/index.php/Beginners'_Guide#EFISTUB I created refind_linux.conf with sdax = sda2
# nano /boot/efi/EFI/arch/refind_linux.conf
"Boot to X" "root=/dev/sda2 ro rootfstype=ext4 systemd.unit=graphical.target"
"Boot to console" "root=/dev/sda2 ro rootfstype=ext4 systemd.unit=multi-user.target"
and at Point 6 X=a, Y=1:
# efibootmgr -c -d /dev/sda -p 1 -w -L "rEFInd" -l '\EFI\refind\refind_x64.efi'
GRUB is quite straightforward.
After restart I got "no bootable device" error. The strange thing is that in BIOS I can see and select "rEFInd" or "arch_grub" in booting options, but anyhow it just won't boot.
Thank you for your help.

totolotto wrote:rEFInd boot manager shows 2 Arch logos:
1) Boot EFI\arch\vmlinuz.efi from 512 MiB FAT volume
2) Boot boot\vmlinuz-linux from 6 GiB ext4 volume
This means that you've got your kernel (or possibly different kernels) stored on two partitions. The first looks like it's a kernel on your ESP, and the second looks like it's your root (/) Linux filesystem, accessed via the rEFInd ext4fs driver. To simplify your life, I recommend deleting the kernel from the ESP and using the kernel in your Linux /boot directory (that is, kernel #2). If you try to keep both of them, you'll have to copy new kernels from /boot to the ESP whenever you upgrade your kernel, and you'll end up with two entries in rEFInd that boot the same kernel, which is sort of pointless.
That said, if you don't want to use rEFInd in the long term, copying your kernels to the ESP, or reconfiguring your mount point so that the ESP is mounted at /boot and therefore your kernels get stored there automatically, can make sense. Given where you are, though, the quickest path to an efficient setup is to just ditch the kernels on the ESP and boot your kernels off of your root (/) partition's /boot directory.
totolotto wrote:With regard to "boot into Arch directly" I understand that it is possilbe with efibootmgr described here, however efrbootmgr does not work for me
Some people do like to boot their kernels directly, without using rEFInd, gummiboot, GRUB, or anything else. Note that efibootmgr isn't involved in the boot process per se; it's just used to set up the firmware's boot manager. Thus, saying you want to "boot with efibootmgr" (or words to that effect) is confusing, even to experts -- because this makes no sense, it's not clear what you really want. This uncertainty has been cleared up in subsequent posts, but I want to point it out to help you (and perhaps others who read this) communicate more clearly in the future.
FWIW, I tend to agree with WonderWoofy on this score -- although it's possible to configure the firmware to boot the kernel directly, the down sides to this approach more than outweigh whatever small speed benefits you get from it. In your case, totolotto, given the problems you're having with efibootmgr, it may not be a practical alternative -- at least, not unless and until you can overcome those problems.
WonderWoofy wrote: I think a better option would be to give rEFInd a timeout of zero. I believe there is a key (or keys?) that you can hold down to have the menu show up when the timeout is set to zero. This is how gummiboot works anyway,
rEFInd doesn't have a 0-timeout option. In rEFInd, setting the timeout to 0 disables the countdown timer, so it never times out. The closest you can get to a 0-timeout in rEFInd is setting it to 1 second. If you must have a true 0 timeout, use gummiboot. Unfortunately, that means you won't be able to read the kernel files from a Linux filesystem, but mounting the ESP at /boot can create something that works about as well. Doing this will require some significant reconfiguration from where totolotto is now, but it can be done if getting a 0-timeout configuration is important.

[Solved] Can't boot, root device not found

I recently performed an update of udev and my kernel and after this I am unable to boot the normal kernel or the fallback. When I try I get this error:
ERROR: Unable to find root device '/dev/disk/by-uid/03619a2f-908f-4724-ba4b-1fb3985e382b' You are being dropped to a recovery shell Type 'exit' to try and continue booting sh: can't access tty; job control turned off
Typing exit results in me dropping to another shell and if done repeatedly a kernel panic. I attempted to boot via the grub console using the sda device block but I came up with the same error. When I look in /dev through the recovery console that comes up the sda* blocks aren't present.
I need to know if there is a way to do this without entirely reformatting my system, I also don't have easy access to another computer but I have an android phone. Any assistance is greatly appreciated.

This has been solved.
For anybody's reference:
From the recovery shell I had to load the modules ahci and sd_mod and that got the sda* to appear in /dev. After that I had to mount /dev/sda3 (my root partition) under /root and /new_root and then enter 'exit' to continue booting.
Pretty much:
modprobe ahci
modprobe sd_mod
mount /dev/sda3 /root
mount /dev/sda3 /new_root
exit

[SOLVED] USB Installation Stuck

I used
dd bs=4M if=/path/to/archlinux.iso of=/dev/sdx && sync
to create my USB, but it won't do anything. I boot from USB, the only output it gives me is: "ISOLINUX 6.02 EHDD Copyright (C) 1994-2013 H. Peter Anvin et al" with a flashing underscore on the 2nd line.
I can't type any commands or get any response from the system whatsoever. I've tried formatting the drive as FAT32 and NTFS, with the same result either way.
I used the 2014.03.01-dual.iso file from the site. USB written from a Lubuntu system.
Any guidance would be truly appreciated.

[SOLVED] Root fs cannot be found on boot (initramfs works)

Hi all! Long time lurker, first time poster.
I'd been using catalyst drivers since I started out on Arch. I knew there were conflicts during updates involving catalyst, so I've never updated my kernel or Xorg during "pacman -Syu" updates. I'd specifically blocked them in pacman.conf. However, I recently decided to switch to open source ati drivers and in doing so, decided to update my entire system including the kernel. Everything went smoothly, but upon reboot I'm getting the dreaded "root filesystem cannot be found" error.
Root device '/dev/sdb6' doesn't exist, attempting to create it
ERROR: Failed to parse block device name for '/dev/sdb6' unknown
ERROR: Unable to create/detect root device, '/dev/sdb6'
Dropping to recovery shell.. type 'exit' to reboot
Note that the initramfs worked, it's just it couldn't get into my root partition even though I can mount it without any problems from the live CD.
I set about trying to fix my problem. Here is a list of things I've tried.
1) Using the liveCD, I chrooted into my install (mounting proc, dev, etc. in the process) and did
depmod -a
followed by
pacman -Sf kernel26
which completed with no errors problems. This didn't solve my issue.
2) Using the liveCD, performing
mkinitcpio -M
and ensuring my mkinitcpio.conf file contained all the listed modules. I then rebuilt the initramfs with another
pacman -Sf kernel26
This didn't solve my issue.
3) Playing with grub, replacing my UUID lookups with /dev/sdb6. I also tried different combinations (see this thread) to check the bios and grub were matching up. I did the suggested rootdelay=8 and rootfstype=ext3 stuff, too. This didn't solve my issue.
4) Using the liveCD, I did another depmod -a then downgraded my kernel to the older package found on the 2008.6 CD. Mkinitcpio completed successfully, everything seemed fine, but... This didn't solve my issue.
I've done these steps over and over again in various orders, trying different combinations, but I've not had any luck.
Here is my current mkinitcpio.conf file:
MODULES="pata_acpi pata_jmicron ata_generic scsi_mod ahci ata_piix ext3 ahci libata cdrom ide-core ide-pci-generic jmicron ieee1394 ohci1394 atl1 mii sr_mod usbcore ehci-hcd uhci-hcd jbd"
BINARIES=""
FILES=""
HOOKS="base udev autodetect pata scsi sata usb net usbinput keymap encrypt filesystems"
Here is the important bit of my grub file:
Without UUIDs:
title Arch Linux
root (hd1,5)
kernel /vmlinuz26 root=/dev/sdb6 quiet vga=869 rootdelay=8 rootfstype=ext3
initrd /boot/kernel26.img
title Arch Linux (fallback)
root (hd1,5)
kernel /vmlinuz26 root=/dev/sdb6 ro quiet vga=869 rootdelay=8
initrd /boot/kernel26-fallback.img
With UUIDs:
title Arch Linux
uuid ec450c30-5197-4330-9831-914eafad66ce
kernel /vmlinuz26 root=/dev/disk/by-uuid/ec450c30-5197-4330-9831-914eafad66ce ro quiet vga=869
initrd /boot/kernel26.img
title Arch Linux (fallback)
uuid ec450c30-5197-4330-9831-914eafad66ce
kernel /vmlinuz26 root=/dev/disk/by-uuid/ec450c30-5197-4330-9831-914eafad66ce ro quiet vga=869
initrd /boot/kernel26-fallback.img
Any ideas, help, suggestions, fixes, etc would be greatly appreciated. I just felt like my arch install was damn near perfect - I'd hate to have to install everything again!
(Edit: Just fixing something I'd messed up in my attempts to fix it, as kindly pointed out by Karol. It didn't fix the problem, though.)

I tried keeping (hd1,5) the same and changing /dev/sdb6 to /dev/sda6, etc. I always through that the grub root (hd0,5) wasn't correct, the initramfs would not be able to show up and I'd just get a grub error. What I have tried so far hasn't worked, but I might try changing to (hd0,5) instead of (hd1,5) in a little while.
With regards to the other links, they seem to suggested lots of things I've already tried. The list is getting quite long now!
I have tried reinstalling kernel26, downgrading kernel26, using the fallback image, made sure mkinitcpio.conf contains my filesystem type, made sure mkinitcpio.conf contains my hdd controller module, tried rootdelay=8 a few times... and my mkinitcpio seems to work, so I don't think the problem is with my mkinitcpio.conf file.
Phew! Thanks for your continued help... I'm sure this problem will get solved eventually (and I bet it'll be something simple!). At least I'm learning about chrooting, initramfs, etc.
Do you think it's worth trying to change root (hd1,5) to (hd0,5)? I imagine that would only cause grub to give me and error and not even be able to find the initramfs!

Arch Linux USB installation does not boot Correctly [SOLVED]

Hello,
I created a bootable USB stick with Universal USB Installer on a Windows System.
When I try to boot it, it shows me a Gummiboot Boot Loader Switch, where I can switch between two EFI shells and ArchLinux installation media.
When choosing the installation media, the screen flashes and after that, it shows the following lines:
:: running early hook [udev]
:: running hook [udev]
:: Triggering uevents ...

Falling back to interactive promt
You can try to fix the problem manually, log out when you are finished
sh: can't accsess tty; job control turned off
[rootfs /]#
In UEFI menu I unabled secure boot and fast boot.
Can anybody tell me what I can do to boot the istallation media correctly?
Thanks for your suggestions

Welcome to arch. I suspect this is the problem:

The error message you get is the same as those encountered by people who try to use unetbootin (eg here). I know Unetbootin does not work to create bootable arch media - perhaps the windows tool also doesn't.
Did you see and follow the tip here? It seems that tool will create working usbs, but you have to fix the label.

My 2009 iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple log

My late 2009 27" iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple logo again. This could possibly be an HD failure, but then why does Safe Mode still work and the USB install not work? Any ideas?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.

I have already tried this :
https://discussions.apple.com/message/21796614#21796614
and this:
https://discussions.apple.com/thread/3435734?start=15&tstart=0
but neither of them have helped me to get the bootcamp work properly. Every time i try to modify this fie i get an error.
Please any help would be welcome.

No problem, forget the daemon tools and Microsoft usb tool, use BooTcamp Assistant for making bootable usb of windows 7 using that .iso.
you can do the following :
1. Add your Boot Rom Version(from system info) under DARequiredROMVersions.
2. Add Model Identifier(from system info) under PreUSBBootSupportedModels
3. Delete "Pre" from "PreUSBBootSupportedModels", so you have "USBBootSupportedModels"
The first 3 steps are same as before and if its not clear you can easily google solutions with screenshots.
The next step is only for OSX 10.9, as it employs some kind of code signature to prevent you from changing info.plist and cause bootcamp to crash.
4. Open your terminal, use the following command
sudo codesign -fs - /Applications/Utilities/Boot\ Camp\ Assistant.app
Sudo means using administrator privilege and u need to enter your mac password. And the command resigns the bootcamp application so that it runs with the new info.plist file and not crash.
5. Continue on with your installation....
Cheers.
P.S. back up info.plist before u change anything.
I installed windows 7 ultimate 64 bit two days ago using this mehod. It is working perfectly. Hope this will solve your problem.Please do make a backup of ur macbook before partition, for safe side.
while using that command mentioned in step 4., may be you get a option to download xcode or something like that, just click ok and download and install that, in my case it was about 101MB.

Can't boot from windows 7 usb installation media

When trying to boot from windows 7 usb installation media no efi boot option availiable. Using "boot from efi file" option whith each and every .efi file on installation media results in a message saying "The selected boot device failed. Press <Enter> to Continue".
USB installation media created using original windows 7 iso image and couple diskpart commands(resulting in clean flash storage with a single active primary partition) plus simple copying of the iso image's contents on usb flash.
Enabling/Disabling SecureBoot doesn't have any impact whatsoever.
Installation boots from aforementioned media successfully when CSM enabled, though i would really prefer installing Windows 7 in uefi mode. Which microsoft claims Windows 7 supports.
Any help or suggestions would be much appreciated. Thanks in advance.
PS: my disappointment in this particular HP notebook is unspeakable. Aside from issue of the current topic, It keeps defaulting to windows boot manager when dual-booting windows & linux no matter what i do, and windows 8.1 Pro is constantly BSODing whenever i try to run fullscreen games on high-performance GPU whith every graphics driver i could possibly install (including both hp's own and amd's). Found silly workarounds for both of these issues, however still hate HP treating it's customers that way.

Booting from USB 2.0 port or DVD with SecureBoot disabled gets me to a screen saying "starting windows", just before the actual setup begins and then system simply hangs. Still unable to install. Thanks for your suggestion though.

[SOLVED]Hanging after booting from installation media

Yesterday I booted from a rw-DVD got to the terminal and could execute commands, connect to the internet and use elink etc no problem. I didn't go through with installation as I wanted to read up more on partitioning my drives for dual booting before actually doing so.
Trying the same thing today, and it hangs soon after I boot, regardless of whether I do anything. Printing the following:
nouveau E[ DRM] failed to idle channel 0xcccc0000 [DRM]
pci_pm_runtime_suspend(): nouveau_pmops_runtime_suspend+0x0/0xf0 [nouveau] returns -16
INFO: rcu_preempt detected stalls on CPUs/tasks: { 6} (detected by 1, t=18002 jiffiess, g=974, c=973, q=604)
This is without me typing anything. If I try to execute a command quickly after booting it sometimes works, but after a couple of minutes it will complain of a soft lockup.
I've tried burning another disk, and using a USB installation media, but the same thing happens. Any thoughts?
Edit: Trying to run it on a laptop with i7-4700MQ, 16GB ram, and Intel(R) HD Graphics 4600 / NVIDIA GeForce GTX 770M
Second Edit: Booted with nomodeset, which worked and allowed me to install. Just trying to sort out the sodding boot loaders now...

Welcome to the forum.
First of all, you should get in the habit of using [ code ] tags when posting code, not [ quote ] tags (well, unless you want to apply some styling to it, like bold, italic, etc).
This is wrong:
# umount /dev/sdc
This is correct:
# umount /dev/sdc1
You were trying to unmount the drive as a whole, which obviously isn't mounted, instead of the first (and probably only) partition. Had you followed the advice from the note to use blkid and check if it's mounted, this wouldn't have happened. But the fact that a DVD produced that error puzzles me... I have no experience with UEFI, but I think you need to press F10, F11, or something like that, to able able to get to a UEFI boot menu, and choose the optical unit as source.
I hope you used a BitTorrent client when downloading the ISO, and not some direct link (which are prone to CRC errors). If you used a direct link, then check the MD5 and make sure that it matches the one from the Download page. For future reference, torrents are checked while they're being downloaded.

Can't get USB installer to boot on Thinkpad S431

Just got a refurbished laptop, and can't figure out how to get the USB installer to boot correctly. I've tried EFI only, EFI+compatibility, CSM disabled/enabled etc. I can select the USB drive and it gets to the Arch menu, then when I select the first option to start the installer it reads the USB for a few seconds then just sits at a black screen. Specs: Thinkpad S431, Core i5-3337U, Intel 4000. I've tried several Arch isos, including 7/14 and 5/14. The USB drive will boot/install in my desktop machine with no problems.
Thanks for any help

Since it is Intel graphics, it might have been an early KMS issue. That is, there is no possible way to get early KMS going from the installer. In this case, you would just need to use 'nomodeset' on the kernel command line. If you were able to use the UEFI shell, then you were probably seeing the gummiboot boot manager. So according to this page, you need to hit 'e' to edit the kernel command line.
