Because the computer CD drive is broken and cannot install the system from the CD drive. I am currently using XP and want to install 2000, so I copied the 2000 installation files to the hard drive. Then I did install 2000 using Dwarf DOS, but I can't format the C drive. The original XP is still there. To format the C: drive, I can only use a boot disk to format in DOS. However, when using tools like USBOOT to make boot disks, I can't enter DOS and it prompts "the operation system si missing". Please, everyone, come in and give some pointers on how to solve this boot disk problem. I don't want to use XP anymore and want to use 2000.
