Ok, my computer had been having problems before but now when i'm booting up my computer I get the blue screen that's says unmountable_boot_volume right after the starting windows screen. I cannot get windows to start in safe mode or any of the other advanced boot options. The only time I don't get the blue scren is when I try start up repair, which just causes a black screen with the cursor. I googled the problem and from what I can gather I Need a windows 7 disk to repair this problem but my problem is I have no disk nor can I get a hold of one. Is there some other way to fix it without the disk?
