Thanks again to everyone's reply, just to feedback on the results.
I had to go into the bios to set the dvd drive as the boot drive to run the
xp cd, so I applied this to the c: drive.
The bios settings had changed so my master drive was no longer the 1st boot
drive option, I changed this and it booted okay with everything in tact.
All seems fine at the moment.
Thanks
