pixiejmcc said:well, i'm pretty sure the hard disk is gonna die. Presumably all I have to do is buy a new hard drive. I figure it would be best to buy an external one, so i can transfer everything from the old one to the new one easily. I checked on ebay and they seem to cost roughly £70. Any advice on what i should get?
Get an internal drive. I don't think ANY USB drive is bootable unless your BIOS supports that. It isn't hard to replace an IDE drive.
