Your computer was unable to start

Your computer was unable to start


My computer was operating on battery, without warning the battery died. After plugging the computer to power and turning it back on, it takes me directly to:

"Startup Repair"
"Your computer was unable to start
Startup Repair is checking your system for problems
If problems are found, start up repair will fix them automatically. Your computer might restart several times during this process.
No changes will be made to your personal files or information. This might take several minutes." Followed by a loading bar that says searching for problems.
After leaving this on for a while it gives the system restore option, however this just takes me back to the previous screen. I cannot cancel the Start up repair and I can't access safemode. After searching for over an hour the only solution i've found so far is reinstall the OS, however my computer did not come with the OS disc .

I am using a Toshiba Satellite with windows 7,

NO help here,
After many, many years and thousands of dollars spent with microsoft, it's time to make the move to apple
