cannot format drive

i have just reinstalled xp on drive D: vista is on drive C: and i cannot format or delete C:
can you please point in the right direction

 

Don't do this, or else you won't be able to boot your system.
Your boot.ini file is located on C:\ even if you have 5 drives and 5 operating systems on each.

Anyway, it looks that you don't have a problem formatting and deleting (you don't have important data on your drives)

So, just boot up your Windows XP CD and install it on C:\ (after you format it using the CD - just don't select "Leave the current file system intact")

After that, you can delete Windows XP on D:\ without any problems.

 

thank you Amjad i will try what you said .
