Well, recently i have updated to window 7, home edition. I have upgraded from my XP sp2, but now, i want to go back to XP. I cant restore my pc because my cd drive is broken. So is there anyway to restore my Sony Vaio? & when i reboot my comp and at the beginning screen, i press f11 to go into system restore but nothing happens, its just reboots. so is there any way to restore my sony vaio back to factory?
