I have a 20GB unpartitioned hard disk and a single-volume 80GB hard disk with Windows 2000 on it (set up as a standalone/workgroup computer) and about 60GB of precious data. I plan to do a clean install of Windows XP on the 20GB disk and I want to delete the entire Windows 2000 installation off the 80GB hard disk first, leaving only my data. However, formatting or deleting the whole partition is out of the question, as there is too much data to consider backing up and I don't have a DVD writer. And as it is an NTFS partition, I can't simply boot from a Windows 98 boot disk and delete what I want. I have tried booting off the Windows XP CD and using its Recovery Console, but that won't really allow me to do anything because of all the security.
ALSO, if I find a way of deleting the entire Win2K installation but leaving my data, then go and install XP on the 20GB, will XP be able to read my data, as the Win2K Security Accounts Manager containing the details of permissions to my data will be gone?
