[SOLVED] Grub Entry to boot via UUID

I'm trying to get my system booting by UUID but I am having issues with the grub entry as it won't boot. The following is the non uuid one that works:
# (2) Arch Linux
title Arch Linux sda5
root (hd0,4)
kernel /boot/vmlinuz-linux root=/dev/sda5 ro
initrd /boot/initramfs-linux.img
And below are the two that I have tried for uuid:
title Arch Linux by UUID (sda5)
uuid 857136db-0356-46bd-9fff-0126b575218b
kernel /boot/vmlinuz-linux root=UUID=857136db-0356-46bd-9fff-0126b575218b
initrd /boot/initramfs-linux.img
and
title Arch Linux by UUID (sda5)
uuid 857136db-0356-46bd-9fff-0126b575218b
kernel /boot/vmlinuz-linux root=/dev/disk/by-uuid/857136db-0356-46bd-9fff-0126b575218b
initrd /boot/initramfs-linux.img
Can someone point out which bit is wrong?
Thanks

Try:

kernel /boot/vmlinuz-linux root=/dev/disk/by-uuid/857136db-0356-46bd-9fff-0126b575218b

You may need the root (hd0,4) line as well. I think that is required to tell Grub where to find it's intermediate files. It would go in front of the kernel line.
Edit: I assume, of course, that your UUID is correct You might check that.

[SOLVED] Grub Problems Can boot Arch w/ grub edits only

I had 3 Linux OS's installed on this computer, Arch and 2 versions of Ubuntu on one hard drive.
The MBR belonged to Ubuntu, using grub2. I decided to get rid of the older Ubuntu (sda8 and 9) and add it's HDD space to my Arch home (sda12). Used the current Gparted live to modify the partitions and all went well, but of course, the numbers changed getting rid of 2 partitions.
No boot upon restart so I decided to get Arch's grub back to the MBR with the new partition numbering scheme.
Using a live CD, I used the grub shell, find /boot/grub/stage1.....etc, etc. and after a bit of fumbling, grub indicated success in the shell. When I was through though, a reboot was not successful, although the current stable grub was now written to the MBR. I edited the lines using grub edit option, and got Arch to boot, and figured out the correct partition numbers. Next I edited the menu.lst to reflect the new sda numbers.
Now rebooting results in a long delay when grub should be on the screen, and the numbers on the Arch entries reflect the old numbers still!! I double checked thinking I forgot to save the edits to the menu.lst file, but they are correct. I can boot Arch, but have to edit the lines each time.
The current partitions are as follows. I edited the terminal output to show details.

I have a few questions regarding a separate boot partition for Arch.
Should the grub> root (hd0.0) command be directed to the root or boot partition.
My handy printed emergency guide says: Set grubs root device to the partition containing the boot directory.
OK.....Writing it out now, it seems clear, so I'll try reinstalling grub from a live CD.
Why does grub have incorrect partition numbers even though the menu.lst is correct?
There are only 2 OS's on this box now, and one contains grub2.
Is current grub able to interact with grub 2 if I screwed something up on the install?

OK
I managed to fix the problem of grub not reading/using the menu.lst file. Not sure WTF it was reading and where that file was located!
The problem seems to have been the most insignificant detail.
When using the grub terminal, I did not execute the quit command when I was through. I just closed the terminal and rebooted.
After repeating the following code via live CD a few times:
$ sudo grub
grub> find /grub/stage1
grub> root (hd0,7)
grub> setup (hd0)
Grub still didn't read the current menu.lst.
This morning I got things to work correctly and grub to read the current menu.lst by adding a quit command and returning to the linux shell prior to rebooting.
I used the following commands:
$ sudo grub
grub> find /grub/stage1
grub> root (hd0,7)
grub> setup (hd0)
grub> quit

(solved) Grub won't boot Vista

Hi!
Just installed Arch Linux and it is great. But after installing Arch I'm not able to boot Windowas Vista. I googled it and added Windows to /boot/grub/menu.lst. Now there is an entry for Vista, unfortunately the bootprozess fails.
Vista is sda1 and I'm able to mount the partition. So it shouldn't be damaged.

Grub entry to boot next bootable device

Hi everyone,
It's not really a newbie question, but I didn't found a better place to post.
I would like to add an entry to my grub menu.lst that will just search for the next bootable device (CDROM, USB or Floppy) and boot it.
So I would always boot on my hdd, and when I hit this option, boot for exemple my usb debian live if it is plugged, or a bootable cd.
Is it possible?

You may need the root (hd0,4) line as well. I think that is required to tell Grub where to find it's intermediate files. It would go in front of the kernel line.

[SOLVED] Grub won't boot into Arch...

So, this all started when I got this wacky idea of trying Debian on a separate drive.
Installs great, boots up and get a blank screen with blinky cursor..not in the mood to mess with it since I can't find
a reasonable answer for what is wrong with it sooo I boot back into Arch but now I get Error device not found with a "Grub Rescue>" prompt.
Not sure what to do now. I installed grub to the drive I was installing Debian on but it seemed to screw with my precious Arch too
I looked around the forums for help but couldn't find anything.
Also, it goes from post directly to the Grub Rescue prompt

[SOLVED] Grub refuses to boot Arch on a dual boot

Hi,
After hours of trying things out and searching the web for answers, I finally gave up and joined this helpforum.
I found several similar topics, but none seemed to work.
So here's the deal.

sda1 (/boot)
sda2 (Windows7, bootflag)
sda3 (/swap)
sda5 (/)
sda6 (NTFS ExtraData)
So i'm trying to dual boot windows7 and arch.
my menu.lst looks like this:

I think that the lines
root (hd0,4)
are wrong. They are for GRUB's root (which is /boot), not /. So I think it should be
root (hd0,0)
instead.

[Solved] Grub Menu at boot How to remove?

There is a pesky dialog box that starts when the computer starts. It is open for 4 seconds then moves on. It says something about choosing a grub and gives two options. It automatically defaults to the first option after 4 seconds. Does anyone know how to eliminate this and have it automatically default to the first option without the 4 seconds?

This is true, but the OP has made it sound as though he is following the wiki, which instructs you to use the recommended /etc/default/grub.
@OP, grub is not necessarily the right way to go about things. If you really like and know lilo, use that instead. I think the ability to choose your software as you please is one of the really defining aspects of Arch Linux.

GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB
nothing but "GRUB" came up.
My menu.lst:
default 0
timeout 3
color light-blue/black light-cyan/blue
title Arch Linux
root (hd0,0)
kernel /vmlinuz26 root=/dev/sda3 ro vga=773
initrd /kernel26.img
Title Arch Linux Fallback
root (hd0,0)
kernel /vmlinuz root=/dev/sda3 ro vga=773
initrd /kernel26-fallback.img
version: 0.8beta2
I haven't found any threads about it, if there's any i'm sorry for bringing up a new one.
any suggests?

Maybe you should start a poll "Vote for the most useless linux error message" ;)
True, not that good error message ^^
This is how I did it:
boot: arch root=/dev/sda3
grub
root (hd0,0)
setup (hd0)
quit
reboot

[solved] grub won't boot unless live cd is inserted

Hey everyone,
I'm trying to get Arch working on my home computer, however I'm having troubles getting grub to boot. After following the beginner's guide and running through the usual steps, I restarted my computer to boot into my dual-booted Arch/Windows computer. However, every time I try to boot, it fails, reboots, and tries again. Here's what I see on my screen moments before it reboots:
Loading Operating System..
Boot from CD/DVD :
GRUB loading..
After that, it reboots. However, if I insert a live CD of arch and select "Boot existing OS", I get
Booting..
GRUB Loading..
Welcome to GRUB!
and then it goes straight to grub. Does anyone know how I could best start to debug this issue, so that I don't need the live cd just to boot into grub every time?
Thanks!

And what happens if you change it?
It was a hard drive boot priority issue. It had nothing to do with the CD having first boot priority or not. I have two drives, and it was attempting to boot from /dev/sdb first, which was the incorrect drive. Switching boot priority between the two drives fixed this. I'll update the topic.

[SOLVED] Grub entry for Arch console-mode

Is there any way to add a grub menuentry to start arch without x?
Last edited by Quatro (2014-08-21 00:14:42)

By menuentry i assume you mean one other than the default for arch.
There is, I believe this may help you. https://wiki.archlinux.org/index.php/GR … b-mkconfig
Currently on phone so its too hard to give exact instructions atm. Internets out -.-

[SOLVED]Grub fails to open dm-crypt+LUKS volume on boot(Waiting 10s..)

I know there are quite a few solved posts like these but it's usually because of "mkinitcpio -p linux" not being regenerated.
My problem is after boot Grub says:
running hook [udev]
running hook [encrypt]

Things I tried:
Replace this line in grub.cfg with
linux /boot/vmlinuz-linux root=UUID=d1d0825c-25d1-4cbe-811f-725d9ef8d034 rw cryptdevice=UUID=d1d0825c-25d1-4cbe-811f-725d9ef8d034:cryptroot quiet
Do mkinitcpio -p linux but the hook ecrypt is there, so I assume it's a grub issue.
In
/etc/default/grub
replace GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda6:cryptroot" with actual UUID, etc.
Grub config was made with
grub-mkconfig -o /boot/grub/grub.cfg
Grub was installed with
grub-install --target=i386-pc --recheck /dev/sda

[Solved] Grub errors 18 and 22 when booting from SSD

Hello community,
recently I purchased an SSD drive and am now having trouble doing an Arch install on it. Before that a 2TB HDD was in use. After building in the SSD I partitioned it (msdos partition table) creating partitions for swap, / and /home. Then I copied the files from the old /home partition on the freshly created one and installed Arch on the new / partition. Here's the partition setup:
$ LANG=C sudo fdisk -l

/dev/sdb3 2048 51863551 25930752 83 Linux # new /
Partition table entries are not in disk order
The problem is: booting from the SSD fails as follows: On the first try to select some Grub entry I get an error 22 "No such partition.". On any further try I get error 18 "Selected cylinder exceeds maximum supported by bios".
What works is to boot up the new system from the Grub residing on the HDD. So the problem is just the new Grub install in the SSD's MBR. Also it's not a thing of Grub's configuration, since copying the working menu.lst from the HDD install and reinstalling grub via grub-install /dev/sdb gives the correct Grub entries but selecting them results in the same errors.
So currently I'm booting from the HDD and selecting the boot entry for the freshly installed SSD system there, which works fine. But of course I'd like the SSD to be able to boot without "help" on the part of the HDD.
I tried to activate AHCI in the Bios but it didn't make any difference. The SSD is a Crucial M4 128GB.
Thanks for any hints,
PhotonX

I created a /boot partition now:
$ LANG=C sudo fdisk -l

/dev/sda8 577722368 3907028991 1664653312 83 Linux
Then installed Grub on this partition: "grub-install /dev/sdb4". Then placed the SSD on the first position in the Bios, booted but got the same errors in Grub. So it doesn't matter where exactly Grub is installed, if it's somewhere on the SSD, it fails...
edit: Concerning using UUIDs: I couldn't find any howto regarding Grub (legacy) configuration with UUID's. Could you point me to some example config?
edit2: I now put the SSD on the first place in the boot list and started PartedMagic. But fdisk still recognizes the SSD as sdb and the HDD as sda. I think, the sdX identifier can be changed only by plugging the SSD in the first SATA port and the HDD in the second (while now it is the other way around).
edit3: I tried to install Grub from the HDD installation on the SSD (executed "grub-install /dev/sdb4" from the HDD system) and found out that, though I created a /boot partition on the SSD, the Grub files installed directly on /dev/sdb are used. So I tried to install Grub from the HDD system onto /dev/sdb (executed "grub-install /dev/sdb" from the HDD system) and got error 22 even before Grub's boot list was shown. But maybe it's really a bad idea to install Grub on another drive than the system it belongs to is located.

[SOLVED] Grub error 18 - cannot boot to Windows

Earlier today I tried to install Arch 64bit (I had 32bit earlier) with kdemod to test new KDE4.2. However, after installation I could not boot neither Arch nor Windows. Grub appeared, but every single option gave me an error. I can't remember anymore which error it was, but It doesn't matter anymore. I thought I had made a really stupid and basic mistake while installing, I just didn't know what.
I wanted to test KDE4.2 so much so I installed Kubuntu (yeah, this topic is not related to Arch Linux, I hope that somebody can help me though, move this topic to somewhere else if it doesn't belong here ). Installation was fine, booting to Kubuntu was fine (and upgrading to KDE4.2 was fine), but booting to Windows was not. It gave me a following error:
Error 18: Selected cylinder exceeds maximum supported by BIOS
I googled a bit and found this: http://wiki.linuxquestions.org/wiki/GRUB#Error_18 I reinstalled Kubuntu using /dev/sdb1 as /boot and /dev/sdb2 as / (/dev/sdb3 is windows and /dev/sdb4 is my game partition, ntfs). Before this I had /dev/sdb1 as / and /dev/sdb2 as swap (now I have no swap at all, my 4GB RAM should be enough). The only difference was that at first grub gave me error 15 (I fixed it with Kubuntu LiveCD). After that - no difference.
I need Windows for playing. That's why it's very important that I can use it. [SOLVED] In addition, I should say that /dev/sda is a separated hard drive which is encrypted with Truecrypt. (I said this because I think that Kubuntu tried to install grub on (hd0)...) When I tried to mount this hard drive with Kubuntu, it couldn't do it. I wanted to test mounting on Windows to check if it is just Kubuntu's problem. If not, I'm fucked because this hard drive contains VERY VERY VERY IMPORTANT files. [/SOLVED]
I really need help, please. If somebody can help me, (s)he is my hero.

# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.
## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default 0
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 10
## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
