My dad recently got a Gateway Laptop and within 2 days he got a virus. it infected system files so i thought i would just install windows xp pro on it. it had come with vista home basic and it had TONS of crapware on it. i didn't want to reinstall that back on it because all it did was slow it down. When i tried installing XP i wasn't able to. Under the install menu there were no partitions and the only thing showing up in partitions was Unknown device. i couldn't delete the partition, create one, or install on it. I'm not sure what to do. right now i think the easiest way would be to get a cord to hook the laptop hard drive up to my computer so i can fully reformat it. is there another way? and was it made like this by gateway so people cant install another OS onto them?
