Okay, Dave, understand. there might be one more option,leave all these 
as is and install lucid, 10.04 somewhere new and let its grub set to 
mbr. Still, I think if the problem is the size limitation of your bios, 
you may still have this problem. But at least, you've got your other 
partitions intact.

If you choose -3-, hope you set up a separate /boot partition at the 
beginning of the disk.

Whatever you do, wish you all the best.

Good luck - Goh Lip
