I tried to upgrade win 7 home 64bit to win 7 pro 64 bit, but there was an error, and I was asked to reformat the C:\ at windows startup repair. After doing this I tried to reinstall win 7, and get a screen that states disk is not recognised, please insert win 7 cd and restart. I do this and the same happens. The bios will not let me change boot order, and the only options I get are to cancel (Esc) or continue (Enter). Both options restart the process. The win 7 disk is original and authentic. Have tried 32 bit and 64 bit. No success. The computer refuses to begin installing windows, and remains a paper-weight.
Please help.
EDIT: I get an error message stating 0xc000000f "The boot selection failed because a required device is inaccessible"
EDIT: I cannot get into recovery section to enter Command Prompt. The Bootloader loops at the error screen. Have tried using an external cdROM, different computer disks and have googled bootloader issues.
Please help.
