Corrupted C: drive

[strANGERdeSIGN 0]

Hey, I have a problem with my C: partition.

I used to have win98 on C: and winNT on D:

Then one day my win98 crashed and left my C: with unusable files which some of them i can't delete

My question is how can I format this C: drive from under NT? Will it corrupt my winNT bootup, r there any programs that would do it safely?

reformat c: and then use the winNT cd to repair the install (replace the boot loader)
