[SOLVED] Bootloaders and partitioning (Syslinux and GPT)
I don't understand why this is so difficult.
All I want to do is install Arch over two partitions (boot and root, both ext2) on a GPT disk, doesn't matter which bootloader. But I can't find any obvious way to do this. My understanding of partitioning and MBR's and bootloaders is probably a bit lacking.
When I use gdisk to create the partitions, and then try to install syslinux, I always get an error about not being able to set the legacy BIOS bootable attribute, even if I set it beforehand with gdisk. Tried various things and I have yet to create a bootable disk. No luck with GRUB2 yet either.
Is there a more idiot-proof way to get this up and running? I've looked through the Beginner's Guide, Installation Guide, the wiki pages on these bootloaders, etc. Re-partitioning and re-pacstrapping after each and every attempt at configuring a bootloader is making this take all day.

Follow the steps for GPT while you are in your chroot environment (after running arch-chroot). If sgdisk is missing install the gptfdisk package via pacman.
That did it, thank you.
Three polite responses in a day... Pretty good first impression of the Arch community.
I'm using ext2 btw because I read somewhere I shouldn't use a journaling file system on the SSD in my Eee PC 2G Surf. Hoping that won't create any headaches for me later.

[SOLVED]New Win 7 + Arch Dual on UEFI and GPT SSD
Sorry for asking this question but i am very confused by reading the wiki. But i don't know what exactly i have to do.
There are alternatives for using GRUB2 and UEFI's booting capabilities. Which one should i choose? If i choose GRUB2, i don't need to create a seperate partition for GRUB2? I can install Windows 7 and Arch directly on their own partition without any steps?
And if i choose UEFI way, the wiki says you have to create a partition => 400 MiB. Should i create this for Windows 7 too? Two seperate 400 MiB partitions or one 800 MiB partition?
I will install Windows 7 first.
My motherboard: Asus P8Z68-V Pro / Gen 3
My SSD: OCZ Vertex 3 120 GB
Last edited by Paingiver (2012-03-13 19:19:49)@Paingiver: That 400 MB EF00 FAT32 partition is a requirement of UEFI (UEFI System Partition), not of GRUB2 or Windows itself. Any UEFI system requires it. The UEFI bootloaders of both Archlinux (GRUB2) and Windows (bootmgfw.efi) are installed to this FAT32 partition, but they won't overwrite each other. Do not confuse UEFISYS partition with /boot partition where bios bootloaders and the kernel and initramfs files are stored.
You can have a single rootfs partition (i.e. no separate /boot partition) as that is not related to UEFISYS. UEFISYS partition is required for any UEFI system. -
Hello,
I just finished downloading the updates yosemite in the app store.
when I tried to start the installation, the installation was issued a message like this
"Can't Install OS X on your Computer
a missmatch between the mbr and gpt partition maps is not supported with this operation.
Quit the installer to restart your computer and try again"
what should i do? i have 2 boot .
1 boot mac , and 1 bootcamp windows 7
sorry I am still learning in installing yosemite

MasraiWhat is the version of OS on your Mac that you are currently using?
Open Disk Utility app, and from the sidebar on the left hand side select your physical drive (usually top entry on the sidebar). Then look at the bottom of this window and look for option called Partition Map Scheme. What does it say on your Mac? -

I would like to get data analysis for solving statistic and making graphs, but this function is not in add-in. How should I do? I also set up microsoft office for mac 2011.
Microsoft didn't include that with the 2011 version.

[ Solved ] Issue with Partitioning (setting the boot flag)
I've tried to install Arch a few times. I always seem to run into this issue which affects me later on.
fdisk (fdisk /dev/sda) doesn't provide me with the ability to set the boot flag on any of the partitions. Therefore I have issues when I get to the bootloader bit. (intend to use grub)
When I use cfdisk (cfdisk /dev/sda), while its help does say pressing 'b' will toggle the flag, in all images I've seen of what cfdisk should look like there has been a column marked 'Flags' - that isn't present for me. So, I have no way of knowing if it actually gets set, though I doubt it does.
Partition Table is GPT.
Though,
fdisk -l gives
Disk /dev/sda ~465.8 GiB
Disk /dev/loop0 ~278.2 MiB //Not entirely sure what loop0 and loop1 are...
Disk /dev/loop1 ~32 GiB
Disk /dev/mapper... //the live image.
I'm probably just making a simple mistake - though I have no idea what. Help?
(Ruling out other errors, using latest dual architecture image, (using 86_64 UEFI) on this system; Asus X99 Pro, Core i7 5820k, 16GB RAM, ~500GB SSD, generic video card).
Last edited by AndyWM (2015-06-10 17:21:20)It's okay - I just decided to follow the beginner's guide again. It recommend the use of parted for GPT when using UEFI. So I just did that, I also went for gummiboot as the bootloader. Never used it before, but it seems to do the job...
Did forget to create a user though, so I'll have to log in as root and do that.
Anyway, I'll mark this as solved. -
[Solved][Hal and Partitions] Newbie problem with hal policy
Hello everybody,
As a new user of archlinux for less than a week I have experienced a great distribution after having been for 1 year on Linux.
After installation I was able to solve most of my problems with the wiki and the forums but there is one problem I cannot resolve.
I have installed Kde 4.2 on my computer and I can mount Usb drives, or CDs with hal (It is in the daemons section of my rc.conf) but strangely I cannot access my other partitions such as my Ubuntu partition (ext3), or the family's Windows partition (Nfts). I have installed nfts-3g for the nfts partition hal refuses to let me access it, I will give you what Dolphin says when I try to access the Nfts:
org.freedesktop.Hal.Device.PermissionDeniedByPolicy: hal-storage-mount-fixed-extra-options no <-- (actions,result)
And for the ext3
org.freedesktop.Hal.Device.PermissionDeniedByPolicy: hal-storage-mount-fixedauth_admin_keep_always <-- (actions,result)
I don't really understand what It means but normally I am allowed to mount partitions.
My /etc/PolycyKit/PolicyKit.conf: http://pastebin.com/m57e94025
And my /etc/dbus-1/system.d/hal.conf: http://pastebin.com/m62861179
I've already tried to configure these two with the wiki and the forums but nothing yet.
If you need more information ask me.
Thanks in advance.
Last edited by auratux (2009-02-23 21:24:29)You might want to reread the Hal wiki re: Permission Denied with automounter. Your /etc/PolicyKit/PolicyKit.conf seems to be missing the lines mentioned in the wiki.

Please help!! I partitioned my macbook pro hard drive in bootcamp so that I could install windows. Everything appeared fine until I got to the install part. I selected the BOOTCAMP partition and then selected format as instucted. That was it. The install could not proceed because it says the partion is in the GPT format instead of NTSF. At this point it erased the "BOOTCAMP" name from the partion but the partion still exists.
I tried to reform by going back on the OS side, in disk utitly, erase and format. It will not allow me to select NSTF format.
What do I do to fix this??
Thanks for you comments.
KristinaIn Boot Camp Assistant when you select the format option the Boot Camp partition it automatically formats the Boot Camp partition as NTFS since this is what Windows requires. There is no option to select NTFS or any other format type.

[SOLVED] /mnt and /mnt/boot on seperate partitions?
I'd like to keep /mnt/boot on my ssd, and keep /mnt on my hdd. I know it's possible to keep /mnt on one partition, and /mnt/home on another, because I've done it on another computer. When I tried to do this new setup, pacstrap failed to install.
Here's what I did
mkdir /mnt/boot
mount /dev/sda7 /mnt/boot #a logical partition on my ssd
mount /dev/sdb3 /mnt #a large partition on my hdd
Any suggestions?
Last edited by cu3ba11 (2013-11-02 21:03:05)The mount point for / during installation is arbitrary. What you need to be asking is "Can / and /boot be on separate partitions?" And the answer is yes.
However, the real problem is that you created and mounted /mnt/boot before mounting /mnt. This is pretty basic stuff, so I suggest you try to figure out why that can't work.

[SOLVED] Formatting and installing windows on another partition
Hello..
I'm planning to reformat my Windows XP partition with GParted and install Windows 7 on it instead.
When I remove the "boot" flag on my /boot partition before doing anything, then format the partition, install Windows 7 on and put the "boot" flag back with GParted live CD, everything should be working fine, shouldn't it?
Or will formating the Windows partition somehow affect Arch (as I'm accessing it with Arch)?
Or will Windows bootloader still overwrite Grub, even if I remove the "boot" flag on it?
Thanks..
Last edited by Psylver (2011-12-01 18:29:42)Thanks.. you were right, but everything worked fine. Took me some time to figure out how to restore Grub as I didn't realize I installed it to a seperate partition.

How do i install grub now ?
L.E. : do not include the boot partition into LVM.
Last edited by psycho (2013-08-01 18:58:18)Your first partition starts at block 63. Grub has gotten so bloated that it now writes to not only the MBR, but also to the space from the MBR (after sector 0) to the start of the first partition, which these days is sector 2048. This new start point is for alignment purposes.
You either need to recreate your first partition and let fdsik align it to sector 2048, or you need to create a grub bios boot partition (as though you were using GPT).
Honestly, although grub2 can handle this, I think putting /boot inside the LVM is a bad idea. It just makes you totally reliant on grub2 with no other bootloader choice. For example, if something in some poorly designed program decided to write some crap to the area between the MBR and the first partition (which applications have been known to do), and you had a USB flash drive with syslinux on it (which the Arch live media has), then you could not set it up to boot your disc.
I think you should use the pvremove command to take that first partition out temporarily, then create two new partitions. One for /boot and one to add back. But this is not going to be very straight forward since you already have four primary partitions. It might be better to convert your partitions to GPT (which is super easy using gdisk) because then you are limited to only 128 primary partitions instead of a measly four. If you do that though, then you will have to make three new partitions if you want to continue to use grub2. You will additionally need the grub bios partition mentioned above. The grub2 wiki page had more info on this. But then you should make the /boot partition and then the partition to add back.
At the very least, you are going to have to remove the first partition so that it can be resized, and then add it back. Hopefully, you have not already filled the LVM space, so that you can easily shift things around. -
[SOLVED] rEFInd and grub
It's actually more a doubt(A newbie one) then an issue.
Last weekend I had a problem loading my kernel with rEFInd(probably after an update, but I sure made some mistake). Then I found out that I could boot the machine and load the kernel with grub, even using EFI so I removed the rEFInd and put the grub. And it solved my issue.
The question is, there are any advantages in use one or another? What is the benefits of using grub and rEFInd? Should I be using rEFInd?
Last edited by AlexVanAxe (2014-01-19 15:36:21)I do the opposite of WorMzy and keep gummiboot as my primary and rEFInd as a secondary. I like gummiboot because it has the option to have no timeout and still show the menu if you hold the spacebar when it loads. I like rEFInd because it allows me to boot from kernels that are on my btrfs partition, so in the event that my kernels don't get properly copied over to the ESP, I can still boot from the ones directly in /boot.
The efistub functionality has not been without its issues though, so it is probably a good idea to not rely on those entirely. I also keep a couple more traditional style bootloaders configured as well. In particular, I keep grub-efi set up because it can act as a fallback to the fallback, but also because it allows me to boot the archiso through a loop mount, which is quite nice.
