warning about knoppix fdisk
I recently suffered through a painfully frustrating reinstallation of both windows 2000 and linux (I'm trying ubuntu right now). I installed a DVD-RW drive in my old slot-1 p3 box, and I guess windows just freaked out.
Anyway, I used knoppix to set up the new partition for windows (fat32), then installed w2k on the partition. On reboot, I got "Missing operating system". After hours of fruitless troubleshooting (also losing my linux installation too in the process), I finally tried my western digital "data lifeguard" tools floppy disk, which said that the partition information didn't match the boot sector information. And I noticed that knoppix fdisk didn't detect the lba geometry on my drives (hence losing my linux installation by monkeying around with partitions and using the wrong geometry). I finally fixed my disks by using ranish partition manager to delete the partitions and make new ones.
So, just a warning: if you use knoppix for any low-level disk operations, make sure it's using the correct geometry.
