It may work and it may not. You may be stuck with Lenovo to provide some drivers and it's doubtful they care to do this. At 7 years, you don't want to waste a Windows license. That desktop likely came with XP. You might contact Lenovo to see if proper media is still available for it but it won't be free.
had vista, but had someone come in and put windows 7. It turns out its counterfeit, so I just bought windows 8. I was told maybe my computer wont be able to take the install. I need some advice Please.
