[Solved] - Root device not found - Unable to boot!

Before posting links to other threads or to the pacman/mkinitcpio wiki page please go through the following.
I know that many others are facing a similar problem, but I am posting this after spending 8+ hours (in 2 days) trying to get my system to boot.
And worst of all I don't have a working CDROM so I have to boot via an iso on a pendrive which is very frustating.
The exact message I get after the GRUB menu is:
ERROR: resume: hibernation device '/dev/sda3' not found
ERROR: Unable to find root device '/dev/disk/by-uuid/...'
You are being dropped to a recovery shell.
Type exit to try and continue booting
Now I have already tried the following, by chrooting into my system:
1. As per the pacman wiki page, boot via live arch, chroot and run full upgrade. Then reinstall udev followed by mkinitcpio and then remake the image.
2. Downgrading to linux-3.3.4-2, udev-182-2x86-64 and mkinitcpio-0.8.8-1
3. Rearranging hooks in mkinitcpio.conf (usbinput before udev), and adding ext4 to MODULES array. Done this in both downgraded version and new kernel version (3.3.8-1)
After trying various permutations and combinations, I have failed and haven't been able to get past the first 8 lines after the grub menu.
An important point to note:
I had used the --force switch for 1 more package other than filesystem while updating which I don't remember now. I had to use it because some packages had gotten corrupted while downloading and I had to upgrade in parts. Also at no point during any of these trials did I get an error while rebuilding the initrd image.
If I remove the resume hook in /etc/mkinitcpio.conf then the first line "ERROR: ... " changes saying that "no hibernation device specified".
Please suggest anything if you can!

Do you know the partition that is supposed to be your root partition?
Grub cannot find it by its UUID. Reboot, at the grub menu, highlight the kernel you want to boot, and press 'e'. You are dropped into a simple editor which will allow you to change the boot command. Replace references to /dev/disk/by-uuid/... with /dev/sdan, when n is the root partition number.
One other possibility. Does your system have multiple drives? Any chance the BIOS could be swapping them ? (On second thought, that would not break UUID, But... it is something to be aware of using the technique I proposed)
If you do not know the partition arrangement, use that limited recover shell you mentioned to go look around and determine it.
Hmm, Thanks for this advice but I can't help saying that I'm not a noob .
Somehow the problem resolved itself with the new kernel update which came about half an hour ago (3.4.2-2). Suppose it will remain a mystery now!

[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] kernel 2.6.27 - Root device not found (2.6.28 too)

since the last kernel update, my ArchLinux won't boot anymore, as it seems to be unable to find the root partition "/dev/sda5". The exact output is:
:: Loading root filesystem module...
Attempting to create root device '/dev/sda5'
ERROR: Failed to parse block device name for '/dev/sda5'
unknown
ERROR: root fs cannot be detected. Try using the rootfstype= kernel parameter.
Waiting for devices to settle...done.
Root device '/dev/sda5' doesn't exist, attempting to create it
ERROR: Failed to parse block device name for '/dev/sda5'
ERROR: Unable to create/detect root device '/dev/sda5'
Dropping to a recovery shell... type 'exit' to reboot
NOTE: klibc contains no 'ls' binary, use 'echo *' instead
If the device '/dev/sda5' gets created while you are here,
try adding 'rootdelay=8' or higher to the kernel command-line
ramfs$
What I have tried:
1.- I have booted with an old Ubuntu LiveCD, and /dev/sda5 seems to be working and healthy, as it mounted flawlessly while in Ubuntu.
2.- I have also found that not even /dev/sda is created from the fallback recovery shell so, obviously, there is no root device to create.
3.- None of the suggested kernel command-line parameters worked: 'rootfstype=ext3' and/or 'rootdelay=8'(I mean, using them separately or both in the same kernel GRUB line) didn't give any positive result, or any behavior change.
And now, two questions:
1.- How can I fix this?
2.- If it's not possible, how can I downgrade the kernel from a LiveCD? I suppose this is possible by booting an ArchLinux LiveCD, chrooting my '/dev/sda5' finding a 2.26.X kernel pacman package and installing, but I'm almost iliterate in kernel issues, and some help would be nice.
Thank you all in advance!
EDIT: Oh, I have also waited for some time to see if the hard disk gets ready after the failed booting proccess but it seems it doesn't, so 'rootdelay=8' wouldn't help anyway, just to give some more details about the problem.

Of course I can, it's quite easy.
First of all, you have to boot from an Archlinux install CD, to have an usable environment. Once you have booted, I will assume a couple of things to make the examples, which are:
"/dev/sda2" is the root partition where the system is currently installed but not booting.
"/dev/sda1" is the boot partition (not needed if you don't have a separated boot partition, obviously).
"/mnt/myarch" is the directory where sda1 will be mounted on the live session.
The kernel version on sda2 is "2.6.27-ARCH", you can find which kernel versions are installed on sda2 by checking the directory names under "/lib/modules/"
Next you have to mount your root partition on any directory and mount the "boot" partition if you have one too:
mkdir /mnt/myarch #Creates the mount directory on the live session, you can use /mnt/ so this command is not neccesary
mount -t auto /dev/sda2 /mnt/myarch #Mount the root partition on the live session
mount -t auto /dev/sda1 /mnt/myarch/boot #Mount the boot partition, if you have to
Now, you'll have to bind three system directories to their true locations on the root partition:
mount -t proc proc /mnt/myarch/proc
mount -t sysfs sys /mnt/myarch/sys
mount -o bind /dev /mnt/myarch/dev
Next step is to use the command "chroot <target> <consolebin>" to "move" the system root to the <target> directory, using the <consolebin> command interpreter:
chroot /mnt/myarch/ /bin/bash
Now, you will be using your system just like if you had actually booted from your hard disk, but running the kernel from the liveCD, so the only remaining step is to generate the initcpio image.
In the example for this step, I will run the mkinitcpio twice, the first one to check that it's correctly generated, and the second to install it, using the parameter "-g". Another thing to keep in mind is that even before chrooting, the liveCD kernel is still running, so you will have tu use the "-k <kernelversion>" parameter to manually specify the kernel to use. Otherwise, mkinitcpio won't be able to find the correct modules to use:
mkinitcpio -k 2.6.27-ARCH #This will simulate the generation, if it runs fine, run the next command
mkinitcpio -g /boot/kernel26.img -k 2.6.27-ARCH #This will actually generate the image
And that's all, this should regenerate a default image. More info about mkinitcpio: http://wiki.archlinux.org/index.php/Mkinitcpio
Hope this heps
PS: Sweden, nice country .
I follow this guide and I saved my Arch installation. I don't know why the HOOKS array in my mkinitcpio.conf just contains "base" :-?
So, just before regenerate the ramdisk image I edit my /etc/mkinitcpio.conf and add all the neccessary hooks and generate. I can bring my Arch box back to life

[SOLVED]kexec into arch fails : root device not found

Hello,
I have a fresh arch install with only base, base-devel and openssh.
I boot on penbuntu, at this point I can see my devices in /dev.
Then I mount my root arch partition on /mnt/rootfs and do :
kexec --load /mnt/rootfs/boot/vmlinuz-linux --initrd=/mnt/rootfs/boot/initramfs-linux.img --command-line="root=/dev/sda3 ro vesa video=vesafb"
which returns :
setup_linux_vesafb: 1280x720x32 @ 10028000 +708000
I then do kexec -e, It seems to start loading the kernel since the screen is cleared and each time it does
[0.845500] i8042: No controller found
:: running early hook [udev]
:: running hook [udev]
:: Triggering uevents...
Waiting 10 seconds for device /dev/sda3 ...
ERROR: device '/dev/sda3' not found. Skipping fsck.
ERROR: Unable to find root device '/dev/sda3' /
You are being dropped to a recovery shell
Type 'exit' to try and continue booting
sh: can't access tty: job control turned off
[rootfs /]#
I tried everything as root in the kexec --command-line, root=LABEL, root=UUID but it always do exactly the same thing, waits for 10s for device and then ERROR and drops to the recovery shell.
Any idea of what's going on ? Why can't it see devices ?
EDIT : If that can help, the kernel from which I am kexecing is 2.6.24.3 and If I try to just chroot I notice :
mount -t proc proc proc/
mount -t sysfs sys sys/
Works but when I :
mount -o bind /dev dev/
It returns :
mount: mounting /dev on dev/ failed: Invalid argument
So somehow I think when the kernel loads it has trouble passing the /dev along and therefore sees no devices. But I still can't figure out what to do.
Thanks in advance

I can't because I'm booting on penbuntu and not arch linux. Anyways the command used in the wiki is similar to the one I'm using.

The IPS 4255 sensor appliance has only a single 512 MB internal CompactFlash module for storage by-default, so this part of the output you posted is interesting:

hdb: 484848 sectors (248 MB) w/1KiB Cache, CHS=481/16/63
As it appears that two (2) 256 MB ("248 MB") storage devices are being detected (despite the model of the first even containing "512MB" in its name).
I'd recommend double-checking that there is nothing installed in the "External compact flash device" slot located on the back of the appliance. See here for reference: http://www.cisco.com/en/US/docs/security/ips/7.0/installation/guide/hw_installing_4240_4255.html#wp2726
If there is a CompactFlash module installed there, eject and remove it, then power-cycle the appliance and attempt the re-image ("recovery") process once more. If the boot output still contains the same errors for hda and hdb, then it is probably a failing/failed CompactFlash module, so an RMA will likely be necessary to resolve.

[SOLVED] Device not found and kernel panic

Hi,
I'm having an issue with the kernel. I get this weird error while booting:
Booting the kernel.
:: running early hook [udev]
:: running hook [udev]
:: Triggering uevents...
ERROR: device '' not found. Skipping fsck.
ERROR: Unable to find root device ''.
You are being dropped to a recovery shell
Type 'exit' to try and continue booting
sh: can't access tty: job control turned off
[rootfs /]# _
I don't have the slightest idea what to type in that shell, so I exit (^D) and get an error with its shell, another one and finally a kernel panic. Do I have to report the other two error as well? I think this might be related to a recent change in my syslinux.cfg. I wanted to add hibernation cabability to my arch, so I added "resume=/dev/sda2" (my swap) to kernel options. It should not yield such a result though. As a matter of fact, I get it even if I remove that parameter at runtime. For now, I managed to boot with Fallback Initramfs.
Here is syslinux.cfg, as well:

Also, don't use "root=/dev/disk/by-uuid/...", that's just wrong. Udev kicks in after the bootloader phase.

3fo. boot device not found

Have hp elitebook 8470p. Yesterday turned it and got error. No boot device found install an operating system E. Thanks

Dear Customer, Welcome and Thank You for posting your query on HP Support Forum It looks like your Notebook is showing "No Boot Device Found" error messageWe will surely assist you with this issue This error message also means that the hard drive is so dead, that the notebook doesn't even know it has one installed. You need to replace the hard drive and reinstall the operating system. If you intend to repair the PC, try removing and reseating the hard drive before buying another one. Maybe the contacts are loose or oxidized The "Hard Disk [3F0] / Boot Device not found" Error message could be because of 3 things as shown below: 1. The Hard Drive or the Partition Structure of the Hard Drive could be corrupted or bad2. We need to check if the Hard Drive Data Cable which connects to the System Board has gone faulty or not. If yes we need to replace the Hard Drive Data Cable3. Bad SATA Controller on the System Board replaces the System Board or Notebook To start with please check if you are able to access BIOS to test the Hard Drive Please Click on the below shown link to perform the Hard Drive Testhttp://h10025.www1.hp.com/ewfrf/wc/document?docname=c00439024&cc=us&dlc=en&lc=en&product=3816360&tmp_track_link=ot_search#N32 If you are unable to access BIOS please remove the Hard Drive and then try to access theBIOS again. Once you remove the Hard Drive boot the Notebook again and press F10 to access the BIOS. If you are able to access BIOS then the Hard Drive is bad Please perform the below shown step if required:Remove the Hard Drive from you Notebook and test it out on a different Notebook. Incase if you are still getting the same error that confirms the fault with Hard Drive Incase if the Hard Drive works normal on a different Notebook please contact HP to get your Notebook diagnosed by an HP Certified Engineer Note: Just to let you know most of the Notebooks have the Hard Drive & SATA Cable built in which cannot be replaced unless we replace the whole Notebook You can Check your warranty Here to verify the status and Click Here to order a new Hard Drive Hope this helps, for any further queries reply to the post and feel free to join us again **Click the White Thumbs Up Button on the right to say Thanks**Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem.

Presario CQ61 - Boot Device not found, Hard dis not exist

Hi i bought my presario CQ61-405AX 2nd hand roughly a year ago and it was almost new, my laptop was running fine, and then it froze, and so i had to turn it off, after i waited 30min for it to unfreeze, it now, when i boot it up, appears with a black screen, with the error
"Boot Device Not Found
Pleae install a operating system on your hard disk
F2 system diagnostiscs"
I went onto hp support and followed the prompts until it did a hard disk test and the error, "Hard Disk Not Exist" appeared
I have no idea how to fix it, i am running Windows 7 home premium, and i fear i may have to buy another hard drive
Thank's in advance

Hi,
The most likely explanation is that your Hard Drive has failed and will need to be replaced, however as a further test, try the following.
1. Create a bootable Ubuntu CD - a guide on creating an Ubuntu CD and the download can be found Here.
2. When created, follow the guide on the link below to Try Ubuntu.
http://www.ubuntu.com/download/help/try-ubuntu-before-you-install
The 'Try Ubuntu' option runs the OS from the CD without the need to install on your HDD. If this runs Ok ( it will be slow running from a CD ), this would tend to confirm that the problem is with the HDD.

Boot device not found, hard disk not exist.... does that mean my computer is dead?

Suspecting that Im in a world of hurt here. I tried turning on my computer and it says "boot device not found" - run in test failed... when I hit F4 and run a hard disk test it says "hard disk not exist". The memory test passes, but under the boot device not found it says in blue "please install an operating system on your hard disk"... and to make matters worse it's making some funny noises when it tries to boot.
Is there any hope at all that this computer will work again? Is there any chance that any of the things I had on my hard disk can be recovered?
This question was solved.

You're very welcome, Jonathan.
dv5 still isn't enough info for me to provide the service manual (in case there are differerent ones for the different dv5 models).
However here is the link to the service manual I randomly pulled.
http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c01550108/c01550108.pdf
Assume it is safe to say all dv5 models come with SATA notebook drives.
So, if you want to spring for $15, you can get this enclosure which apparently has very good reviews.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182138
From what you are describing (noise and stuff), I would say you don't have much of a chance to recover data but that is up to you if you want to try the enclosure or not.
Here is what I recommend:
Yank the hard drive, and power on the notebook.
If the odd noise you heard is gone, then you can pretty much safely assume the drive was the cause, and that replacing the drive, and reinstalling the operating system will solve the issue.
If the noise is still there, then there could be another issue, and it might be risky throwing good money after bad.

Hello hungvocam
Thanks for posting on the HP Forums!
I understand you are experiencing an issue with your notebook. However, since this is a commercial notebook, you should post your issue on the notebook board of the HP Enterprise Forums for a better answer.
Thanks and have a great day!

Boot Device Not Found Please Intall an Operating system on your hard disk. Hard Disk - (3F0)

Hello,
I tried to re-install de OS from windows 7 to windows 8.1 and when the bios update driever was installed and the laptop was restaring it appeared the folowing window and message:
Boot Device Not Found Please Intall an Operating system on your hard disk. Hard Disk - (3F0)
After that i tried a lot of different ways to get to boot device select ...but i couldn't do anything. I removed the HDD and i put it back, i've tried with holding in the same time windows +B and pressing the power button in the same time for 1..2 seconds and then i've waited for at least 1 minute..and it didn't appeared anything on the screen. I've done the hard drive check and it passed. The weirdest thing is that when i want to select a boot device to re-install again the OS, i can't see any boot device to select. I need to mention that i've formatted the HDD in another computer. I dont care about the informations from the HDD beacause i saved all the informations on another device storage.
Please help me repair this problem!!! thanks a lot!
Have a nice evening.!!!

Whenever you get a message stating that the boot device not found it could be because of bad sectors on the Hard Drive. Its not necessary that the Hard Drive Test should fail to determine if the Hard Drive if its faulty or not. Sometimes even if the Hard Drive Test passes the Hard Drive will still not work because of the bad sectors in it.
Best way to find out if its the Hard Drive you can try the Hard Deive on a different Notebook which would help you determine if it's faulty or not.
Could be due to Application or driver conflicts, virus issues, file corruptions due to incompatible applications, improper shutdowns, update failures due to conflicts, sudden power surges, if notebook is dropped etc..
HP will provide a replacement Hard Disk Drive if the Notebook warranty is Active, If not you need buy a SATA Hard Disk Drive from a retail shop nearby
Please make sure you are getting at least equal capacity as the original one in order to use Recovery Disks. If you need you can buy a larger, but not smaller capacity Hard Disk Drive. For example if you have a 500GB Hard Disk Drive you can upgrade it to 750GB Hard Disk Drive but not 320GB Hard Disk Drive
Please try the below shown troubleshooting steps once:
Step 01. Remove the battery and unplug the AC/Power Adapter
Step 02. Press and hold the Power button for more than 30 Seconds
Step 03. Plug in the AC/Power Adapter (leave the Battery out for now)
Step 04. Press the Power button and check if the Unit works normal
If the above mentioned steps does not help, then you can try reseating the Hard Drive on your Notebook
If the issue persists again please Contact HP if your HP Notebook is under warranty, HP would replace the Hard Disk Drive and provide you a Recovery media to restore factory operating system after replacement (if you've not yet created Recovery Discs/USB Media)
Note: Back up all the personal data to an external drive if it's possible. Otherwise you could connect the failed HDD via SATA to USB adapter with another PC or same PC after replacement of HDD & re-installation of OS and try copying /recovering the files.

Hi,
Can you post back with the following.
1. The full Model No. and Product No. of the notebook - see Here for a further explanation.
2. The full version of the operating system you are using ( ie Windows 7 32bit ).
3. Shut down the notebook. Tap away at f10 as you start the notebook to enter the bios menu. Under the Advanced or Diagnostic tab you should find the facility to run a test on the Hard Drive. Post back with the details of any error messages.
