Something NEW... GRUB error.

buccaneere · 02-13-2009, 12:37 PM

Another multi-boot machine, another problem.

I'm workin' on a quad-boot - Ubuntu, XPPro, FC8, and PCLinuxOS.

2 disks on IDE secondary, one disk on PCI/IDE controller card.

I was 3x booting no problem from PCI drive, till I added PCLOS to the PCI drive. I think I over-wrote FC8 loader... How can I tell?

I got a Live boot up now...

Code:

ubuntu@ubuntu:~$ sudo fdisk -l

Few questions:
Which grub error? 22? 15?
I presume Windows = hdc1, but...
Who's on hdd1 and sda1, Ubuntu and FC8? which is which, and where did you put PCLOS?

You could always reinstall grub after locating your menu.lst, whichever drive you were keeping the /boot/grub/menu.lst files; if you don't remember, you can use "find" at the grub prompt. Hope that helps.

Don't remember the GRUB (PCLOS) error; tho' it was a 'find file' error, not numerical. I think it was 'Can't find menu.lst'...

hdc1 = XPPro .......IDE secondary
hdd1 = Ubuntu ....IDE secondary
sda1 = PCLOS .... PCI IDE card
sda2 = FC8. ........ PCI IDE card ... sda2 is also LVM (oops).

I'm still liveCD now.

Is FC8 GRUB conflicting with PCLOS GRUB?

Thanks...

Well, there's only going to be one GRUB in the MBR of sda, which is presumably the boot drive. Or is there an hda (IDE primary) that's the boot drive? It probably doesn't matter if you're using PCLOS grub or FC8 grub, so long as it can find its files. But don't you need a boot partition when your root partition is on LVM? So the question remains: where are the boot files. Sometimes with grub's "find" command, you have to spell it out, and type

Quote:

find (hdX,X)/boot/menu.lst

or use file completion with the TAB key.
hdX is hd0 or hd1 or hd2, not hda, hdd etc...
