Another "GRUB Failed"Question

PipeDreams · 11-24-2006, 10:15 AM

I have(had) a multi-boot box.I re-installed xp the other night and xp re-wrote the MBR.

This has happened before and I usually put my mandriva disk1 back in and rescue/re-install GRUB.

I try that this time and get returned:

exec of sh failed:exec format error
GRUB failed:at /usr/lib/libdrakx/bootloader.pm line 1509
<stdn> line1

The above is from memory maybe spacing errors sorry.

What I really need to do is install GRUB in the MBR and have it point to mandriva's boot/grub/menu.lst which is located at hdb1(hd1,0).

Can I do this with a live distro(knoppix)?

Thanks

There is a way you could do this with a live cd. If the live cd has grub on it you can just install it as you
normally would. If not then you can mount your drive
somewhere and then sudo mount the device list into your
drive and chroot to it and preform the install.
LFS does this when your setting up grub

ill list steps below

if grub is on the live disk

Code:

 
root (hd1,0)  this is hdb1 in linux 

setup (hd1) you can do this but you must make sure that the
 boot loader in hd0 will look for grub here. or you change 
your bios to look on the second harddrive for the boot 
device.

if not then here is the steps for sudo mounting and all that

Code:

 
mount --bind /dev <where you mounted your system>/dev
^this command will populate dev with devices 
chroot into the enviorment and run GRUB 
go back up this post and look at grub instructions

that should get you though doing it.
