I obtained an OEM WXP CD and installed it.
Next time I tried to run the PC it showed 'NTLDR is missing'. So I left it for a few months.
Now I returned to the computer and it showed 'Boot from CD'.
I have now reached to where I receive the following: WXPHome Edition Setup.
CAUTION: A \WINDOWS folder already exists that may contain a Windows installation. If you continue, the existing Windows installation will be overwritten.
All files, subfolders, user accounts, applications security and desktop settings for that Windows installation will be deleted. The'My Documents' folder may also be deleted.
To use the folder and delete the existing Windows installation in it, press L.
To use a different folder, press ESC.
To quit Setup, press F3.
How should I proceed with thus, please ?. Thank you.
