Yesterday my computer was working perfectly fine, but when I turned it on today it was unable to boot Windows. The two options on bootup are "Launch Startup Repair" and "Start Windows Normally", but both options go to System Recovery Options. Startup Repair cannot automatically fix the boot problem and gives the error "StartupRepairOffline" when it's run. The operating systems list is blank when I try System Image Recovery. System Restore also does not work. Memory diagnostics did not find problems when it was ran. The computer identifies the operating system as "Unknown on Unknown Local Disk" on the System Recovery Options menu. I am running Windows 7 Home Premium 64-bit OS. I am hoping for an alternate solution to reinstalling Windows from the original disc.

Thanks in advance for any help.
