Hi, after installation of windows 7 on the hard drive I got error as "An unexpected i/o error has occurred 0xc00000e9" and suddenly my computer restarted. I have Windows xp on same hard disk, but on different drive. Now I am not able to logon to windows 7 as it is not giving me any option to enter the setup of windows 7. Please, can you help me. I am able to enter setup of the Windows Xp. So, please help me.
