Hello, I have recently been browsing the internet trying to find a solution to my problem; however, I have not been able to locate any definite information. I decided to find a forum to ask my question so thank you in advance for any information given. My computer came with Vista when it was the 'new thing' and was terrible. I ran it for awhile but eventually switched to a pirated copy of XP. I then switched to Ubuntu for a few months but returned to XP eventually. I had no problems with this process. Now, I have attempted to install Vista as well as Windows 7. With both OS's the install seems to be performing perfectly but when the loading screen appears with the Windows logo all action stops. The screen either freezes or continues to look as if it were loading but never actually loads. Now, I did use pirated copies of both but both worked on other PCs. The college I attend announced they are giving out free copies of Windows 7 Home so I would like to figure out the problem before I wipe my hard drive again for a failed installation. After failing with both Vista and 7, but still wanting to upgrade my OS, I have come here looking for an answer to what may be causing this. While perusing the internet for an answer I thought it may be a problem with the MBR but I'm not entirely sure.
