If Windows® XP Setup cannot detect your existing installation of Windows® XP, you may be able to install Windows® XP to a different folder and retrieve personal files
You will have got to one of the following prompts
To continue installing a fresh copy of Windows® press Esc
Windows XP Professional Setup
The following list shows the existing partitions and unpartitioned space on this computer
Use the UP or DOWN keys to select an item in the list
To setup XP on the selected item, press Enter
To create a partition in the unpartitioned space, press C
To delete the selected partition, press D
7327Mb Disk 0 at Id 0 on bus 0 on atapi [MBR]
C: Partition1 [NTFS] 7319Mb [4887Mb free]
Press Esc if necessary to get to the second screen.
At this screen, look for the entry for C:
(Example above is C: Partition1 [NTFS] 7319Mb [4887Mb free])
If you do have an entry, and free space is reporting over 1500MB then you may be able to install Windows® XP in parallel. Continue below.
Move the highlight with the arrow keys on the keyboard to the C: partition, then press Enter
Windows® will now ask you to confirm the install. If you are satisfied with your decision then press C.
Now you will be asked if you wish to format the drive, select 'Leave the current file system intact (no changes)' and press Enter.
Windows® will now warn you that the Windows® directory already has an operating system, press ESC to select a different folder.
You will now be asked to change the folder that Windows® installs into. You can change this to whatever you want, a good example is \WINXP. Then press Enter.
Windows® Setup will now continue, and will install Windows®. Follow the prompts
Once Windows® has been reinstalled, you should have a basic copy of Windows®, and some drivers may not be correctly installed. (The most obvious of these may be the graphics driver if your desktop icons look very large)
However at this stage you now have 2 copies of Windows® on your computer which will be taking up unnecessary space, and you should use the current installation to backup personal data and files.
