[SOLVED] GRUB menu: UUID= error message (Bunsenlabs and Mint 13)

Starborn · 2016-01-18 18:52:26

"Hiya" to all Bunsenlaboratorians,

I am having a small problem with the GRUB menu, and I don't seem to find a solution online.

I have Bunsenlabs and Mint 13 xfce (an LTS) in dual boot (and XP, but let's forget about that OS). When booting and choosing Linux Mint 13 in the GRUB menu, for a few seconds I get the error message:

The disk drive for UUID=38d8fcd3-a454-4126-8359-071f67788629 is not ready yet or not present.

Continue to wait or press S to skip mounting or M for manual recovery.

Mint “Maya” boots fine, thought.

I have been searching online for a couple of days, and as I understand it, this error follows after (allegedly) having changed the partitions. However, I did not change any partitions; I installed Bunsenlabs “over” the Crunchbang partition, and I kept and used the existing swap partition.

Here is the result of a bit of homework so far (which I did, while following several webpages because after having used Ubuntu, Xubuntu, Mint, Debian, Bunsenlabs from 2007 until now, I am still just a n00b with some Linux experience):

starborn@capella:~$ sudo blkid
/dev/sda1: LABEL="WINXP" UUID="EE8C266F8C26330F" TYPE="ntfs" PARTUUID="0d070d06-01"
/dev/sda2: UUID="6acfe146-956f-48ea-b6c2-2e104f120879" TYPE="ext4" PARTUUID="0d070d06-02"
/dev/sda4: UUID="89619e60-e84a-4395-ad0c-70b0746462d5" TYPE="ext4" PARTUUID="0d070d06-04"
/dev/sda5: LABEL="DATA" UUID="4EB88D29B88D111F" TYPE="ntfs" PARTUUID="0d070d06-05"
/dev/sda6: UUID="6a285556-fb36-4df4-93a7-7d1b8b79aa53" TYPE="swap" PARTUUID="0d070d06-06"

To clarify: sda2 is Bunsenlabs, sda4 is Linux Mint 13.

The etc/fstab file (in Bunsenlabs) shows this:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

I did an "update-grub" in Linux Mint, too--but as the GRUB menu is "OS independent", the error message still appears, of course.

Why does that error point to a partition that does not exist (UUID=38d8fcd3-a454-4126-8359-071f67788629)?

I noticed that the Linux Mint UUID is not in the fstab file – but the Mint UUID is not the one that the error mentions.

UUID="6acfe146-956f-48ea-b6c2-2e104f120879" is the Bunsenlabs partition.
UUID="89619e60-e84a-4395-ad0c-70b0746462d5" is the Mint partition.
UUID=6a285556-fb36-4df4-93a7-7d1b8b79aa53 is the swap partition.

UUID=38d8fcd3-a454-4126-8359-071f67788629 is in the error message (??).

I am not a pokemon, and no one flipped a coin, but I am confused.

--
A sudden thought: Did installing Bunsenlabs change the UUID of the swap partition (which already existed from Mint), and does that error message point to its changed UUID? (How do I found that out?)

*Still reading online right now*
I see that no swap is used. (I have this odd feeling that that error message has to do with the swap partition.)

starborn@capella:~$ free -h

Swap:         1.9G         0B       1.9G

Is this normal?

Try booting a Live disc and running gparted - you might find the problem showing up in the partition UUIDs. It is possible to reassign new UUIDs to the partitions if necessary, and edit the different fstabs accordingly.

You won't be using swap anyway until your system need it.

Head_on_a_Stick · 2016-01-18 19:54:10

Try this:

sudo grub-install --recheck /dev/sda

If you have problems with swap, confirm that the partition is activated with swapon(8)

Do you have a GPT disk?

If so, systemd will deal with swap automatically and any lines can be removed from /etc/fstab

What probably happened is that you re-use the swap partition, but the bl installer has re-initialized it, giving it a new UUID.
Boot into the Mint system, and check fstab. It will probably contain a swap entry for uuid 38d8fcd3-a454-4126-8359-071f67788629 (the previous UUID for the swap partition)
Edit the Mint fstab file, replacing the 38d8fcd3-a454-4126-8359-071f67788629 by 6a285556-fb36-4df4-93a7-7d1b8b79aa53 (i.e. the new UUID for the swap partition.

Re-running update-grub for the mint system hasn't changed anything, because grub now points to the bl configuration. (init-grub was last run with the bl partition as target)

@Head_on_a_Stick,

sudo grub-install --recheck /dev/sda showed:

Installing for i386-pc platform.
Installation finished. No error reported.

And "parted" gave me "Partition Table: msdos", so that point to MBR, right? (I had to "google" that.)

@xaos52,

The Mint 13 fstab file indeed shows the UUID from the error message!! I did not think of checking in Mint. (Me, n00b! But it was indeed the swap partition, so at least I was on the right track.)

I am writing this in Mint 13 now, and after replacing that UUID from the error message with the new UUID, the error message did not appear after rebooting and choosing Mint in the GRUB menu.

Xaos52 - you are the man (so are you, Head_on_a_Stick, but you what I mean, right?

Awesome.

Thank you all for your time and your trouble to have helped me out with this small thingie.

At Windows forums I often see these "Microsoft MVP's" that try to help Windows users with problems, and they always give those standard answers that are rarely of any use to people. You are tons better than those "MS MVP's". I am in awe.
