My question is: it asks if i want to partition my hard drive. Is it going to destroy everything else on it? I want a dual-boot with XP.
If your HD is ntfs, use the Windows tools to create a seperate fat32 partition (this is where you'll install knoppix). Then run the knoppix installer. Another trick is to pick up a copy of Mandrake and use that to resize the ntfs, then abort the install after the disk has been reformatted and install Knoppix.
