I would try doing a parallel installation to at least allow you to boot up your computer and backup the data you need and then do a complete format and install of XP. Just want to point out, that what you tried to do ended up deleting the Windows Folder on your computer, but all the other problem are still there and hence you are unable to properly install Windows.
------------------------------------------------
Parallel Installation of Windows XPBoot to the Windows XP installation cd by pressing a key when the "Press any key to boot from cd" prompt appears at the top of the screen.
- At the "Welcome to Setup" screen, press Enter to set up Windows XP.
- Accept the License Agreement by pressing F8
- With your current installation selected in the box, press Esc
- Select C: Partition1 [NTFS] in the box and press Enter
- To continue setup using this partition, press C
- Now you should see formatting options...choose the last one, Leave the current file system intact (no changes), and press Enter
- To use a different folder, press Esc
- Name the folder WINDOWS0 (just type a 0 (zero)) and press Enter
The Windows installation should begin. This will install Windows to a new folder, leaving your data intact. Any programs installed on the old directory will have to be reinstalled to the new one. Device drivers will also have to be installed for all the hardware to work as it should.
The data will be located in the Documents and Settings folder (C:\Documents and Settings) under your old user account name...so when you set up the new installation, give yourself a slightly different user account name.
