[ubuntu-uk] Repairing a dualboot Ubuntu-XP system

2011-12-24 Thread David Smith
I have supplied a second hand PC to a friend, dual booting XP and Ubuntu 10.10 
from one HD.  Somehow, he's made a mess of his XP and I need to do either a 
repair-over-the-top install or a full XP wipe and reload.  Since it is the XP 
registry file that is corrupted, I suspect that I would need to do a full WR.

If I do the above, it would (I think) replace the GRUB boot/MBR  with XP's 
loader.  My question is, could I then boot off a live CD and sudo grub update 
to reinstall and rebuild GRUB as easy as that??  Or is it more involved?  It's 
a big enough pain that XP is borked.

Advice appreciated.

This is what I did from a live cd:

su
mount /dev/sda6 /mnt
grub-install --root-directory=/mnt /dev/sda

reboot

then sudo update-grub

replace sda6 with your partition

i Have just reinstelled windows, and selefcted the repair option,  and
this reinstalled windows ontop and left all my files / data intact and
surprisingly left the mbr intact too.

I think you select install then repair,

It is possible that the actual XP version used might have be
significant, all XP is not the same, it was produced over a long
period. For example, early versions do not immediately require
activation, but later versions do.
