Hello - I installed the latest Ubuntu as a dual-boot with XP... I have decided that I'd rather have Backtrack... I have burned the iso... question: Can I safely install BT5 by just telling it to use the Ubuntu partition? Will it just reformat that partition, with a fresh grub? Or do I have to do things the inconvenient way by deleting the partition, using XP boot disc, running fixmbr... etc?
