I had a computer full of viruses and VERY slow. I burned the DBAN to an .ISO. Everything worked fine and it said to give it 12hrs to get everything completed. Thats fine as well. The tutorial I was following said "After the process finishes, you will need to make a win98 boot disk. Boot from the disk, and then type “fdisk /mbr” at the boot prompt. This will rewrite the MBR". So since I have a XP cd is that what they mean by boot up disk?
