View Full Version : [ubuntu] GRUB is borked after last update (7 Sept, 2010)

Whilst I've been using Ubuntu for years now, I don't really do much at the command-line, basically because I don't *have* to (which, to me is the beauty of this OS!). However, the last update via update manager has rendered my dual-boot with Vista on an Asus laptop non-functioning (at least Linux).
What happens is this: after the BIOS splash screen, it says starting GRUB and then, instead of a menu of current and recent Linux versions and the Vista option at the bottom (white text against colour background) it now just shows one line of the menu in magenta... the rest of the menu is black, but the arrow keys will show the other options. Hitting ENTER does nothing: the text line is replaced with a blinking underline which goes back to the text in magenta again when i hit ESC.
I can't seem to ESC or SHIFT to GRUB's command-line prompt at all.

I've boot to the LiveCD and ran a boot_info_script in bash: here is what that revealed:

So, something is stuffed somewhere. No idea where to go from here. Might anyone have any clues what I've done wrong?

Whilst waiting for someone to offer ideas, I've been doing a bit of fumbling around with Rescatux Rescapp: you know, that Debian-LIVE based GRUB fix thing. It actually managed to write a new GRUB for me, so now when I boot, voila: a menu list that looks like it *should* work.
However, selecting *anything from this GRUB menu gives me the error:


Error 11: Unrecognized device string
Press any key to continue...

So, I went back with my Super GRUB Disk and took GRUB off the MBR so that I could at least boot to Vista.
There wouldn't be some simple solution - or one that everyone but *me* is familiar with - to getting the device strings to be recognised? Or do I need to re-install 9.04? From what I've read, I'm not too keen to update to 10.04 at this point: seems like it has dramas 9.04 didn't.

Reinstalling grub from a live cd is pretty straightforward. See this reference: https://help.ubuntu.com/community/Grub2#Reinstalling GRUB 2

Thanks for your reply, Ron. ):P

I'm still using legacy GRUB, based on that boot_info_script RESULTS.TXT file. 1.9.8, I believe.

I *was* able to get the menu back to looking as it should, but the menu doesn't do anything but produce those errors. Do I just try to re-install GRUB again, or is there somewhere else I should be looking?

Thanks to all who respond... this is completely baffling, not to mention a bit frustrating, too.

EDIT: Ooops, I was wrong... based on your article, I must be running GRUB2... I'll have a go at re-installing GRUB2 and get back to you.

I saw somebody post this so I think it's what your looking for with grub-legacy.

I think I am *seriously* messing things up.

I've gone ahead and create a CD with Ubunto 9.10 on it, and using that followed the instructions to restore GRUB2. I followed the 1st lot of steps (the easiest ones (https://help.ubuntu.com/community/Grub2#Reinstalling%20from%20LiveCD)) and it seemed to work, but when I rebooted, it dropped me at the GRUB command prompt.

GNU GRUB version 1.97~beta4

I tried a cat /boot/grub/grub.cfg but got a file not found error.
This is puzzling beyond words...

Robynsveil - If by chance you used the command of the form: sudo grub-install --root-directory=/mnt/ /dev/sdX

If the / following the mount wasn't included, you might get the results you did!

This is goiing from bad to worse.

I've gone ahead and did as suggested: did the GRUB Rescue (https://help.ubuntu.com/community/Grub2#Rescue%20Mode) thing as per that link, and actually got IN.
Once.
Whereupon I immediately updated GRUB 2 as suggested with the update-from-grub-legacy command and now I'm getting the Error 15: File not found again at boot when selecting a menu item. I feel I'm *so* close... :confused: ](*,)

BTW, the menu I *still* see says
Chainload into GRUB 2 up the top, so obviously it didn't really complete the process??

Right, a bit of followup. I'm not going to mark this solved because I never did get a solution that worked properly to the whole GRUB issue. My take is that I'd sort-of set this to fail at some point because I didn't follow through with upgrading from GRUB legacy as I was meant to... I didn't realise at the time that it had not been completed.

What I *did* end up doing was: upgrading to Ubuntu 10.04. The upgrade went seamlessly, preserving all my settings and data and fixing some other, nagging problems I had with Jackalope, which didn't shut down my Asus laptop properly. Lynx does.

So I'm a happy camper, Ubuntu-ing merrily away again, confidence restored. :)
