Hello, I turn on my computer to eventually get a black screen with white cursor that will move around. The Toshiba insignia comes up beforehand as well as the windows four square icon then it is to this black screen and white cursor. I cant seem to get the computer to boot up from Windows 7 installation disc. Sometimes I also get a BOOTMGR image is corrupt. The system cannot boot. message as well. I imagine there is a solution of sorts as it seems many people have had a similar problem. I have a freind who maybe able to fix it seeing he is a computer programmer but that is not until the end of the week. If anyhting else if you have had the same issue and reading this - you are not alone!
