Assuming it's FAT32, you simply need a dos boot disk with a version of dos
that can read FAT32. If you create a boot disk from Windows 2000, that
should work.
If your C: drive is NTFS...I would probably use FDISK to delete the
partition and re-create it. Then depending on what you need that partition
for, you can format it in a couple ways. If you're installing an operating
system on it, I'd just let the install do it. Windows 2000 install usually
will allow you to select the partition you want to install it on, and format
it for you. Worse case scenario, format it in FAT32 and then do the
install...you can either leave it as FAT32 or convert it to NTFS.
Is that sufficient explaintation?
