Hey, I can't seem to install Windows XP on my desktop. It's a HP Pavilion t540.uk (10 year old family computer), which came with XP Home edition. For the last year we let someone else use it and it was returned formatted with no OS. When I use the XP installation disc it shows the error... Unknown filesystem Grub error So i tried installing via USB using WintoFlash and managed to enter text mode setup. It loads all the files then as it says "starting windows" goes to BSOD with error ... 0x0000007B (0xF78D2524, 0xC0000034, 0x00000000, 0x00000000) Any ideas what the cause is? Only suggestion i've seen is to do with changing SATA Mode in BIOS which is not an option in my BIOS. Also can't enter system recovery with F10.
