I have Windows XP Professional installed on my C: drive (an NTFS partition).
For various reasons I want to reformat the said drive and reinstall XP, but I can't find any instructions as to how to do this. My boot disk doesn't 'see' the NTFS partition, and my XP CD-ROM doesn't seem to give me the option to reformat the partition.
I'd like to try this, but when I choose the repair option from the CD-ROM it asks me for the Administrator password, and I don't know what that was. I don't recall setting an Administrator password, and I've tried the ones I would have used to no avail.
I have had a similiar problem before. To get round it I used the Windows 98 boot disk. It doesn't see NTFS, but it you enter FDISK at the command prompt you can use FDISK to delete the Non-Dos partition. Once deleted, exit FDISK and then restart using the XP CD. The CD will then ask you to create a new partition and format the hard drive as NTFS.
