schneidz - I tried dual booting with Ubuntu (versions 8.04, 9.10 and 10.10) and putting grub on the mbr. Didn't like it there on W2K with a BSOD, but no problem with XP.
yancek - Relating to this, where do you suggest I install GRUB? The mbr didn't work, so should I install it to the Linux partition or Windows one?
When there is a problem, I get out my W98SE disk and do a
cmd to reinstall the bootloader, but I can't afford an error with this as I've got loads of programs on W2K.
