THank you for your replies.
I'll install to W7. I bought this new computer desktop from the Ebay for £ 175.00 by wining the bid. It has 500 GB SATA HARD DISK 2 GB DDR3 MEMORY,can be upgraded to 8GB AS ROCK MOTHERBOARD 500 WATT POWER SUPPLY AMD ATHLON PROCESSOR. Black ATX case. But loaded with XP, genuine sticker at the back and i activated it. Nat bad with this money! Wish to keep the XP if it is safe, can use W7 on other computer. Trying to partition this hard drive with EASEUS Partition Master.
