How can i remove windows xp from my mates computer without having the disc as this was loaded on by his buddy, his computer does not seem compatable with xp, and wants to put windows 98 back on cheers Justin...

Here's a bunch of reading for you or your mate

uninstall xp to 98

uninstall xp reinstall 98

This is the jist of it unless you have other circumstances:

The normal way to "uninstall" _any_ operating system is to format
the hard drive and install a new OS of your choice.

However, if you performed an upgrade from Win98/Me, elected to
backup the old system files, and didn't convert the partition to NTFS,
then all you need do is boot into Safe Mode and Start > Control Panel
> Add/Remove Programs. All of these conditions _must_ be met for the
uninstall option to be available.
