Wasn't sure whether to post here or in Laptops.

I have an old Tecra A7 that I'm trying to put XP on. It has the XP pro sticker on the bottom with the key.

I need it to run XP for some car diagnostic software that only runs on (stupid).

Now, the issue is, it won't install windows beyond "Setup is checking your hardware".. It just hangs.

It'll install Ubuntu, mint, puppy linux, vista (blergh), OSX(!!!) but not bloody XP! I've tried 4 discs, 3 bootable USB installs, praying to cows, and even the old "FCKGW" install... 

I'm going slightly mad.

Can anyone shed some light on this?
