I have either Windows 7 Home or Ultimate, I'm not sure. I was doing a restart and left my flash drive in the USB slot while rebooting. I think I screwed up the Master Boot record. The error I'm getting now is stating BootMgr is missing, press ctrl+Alt+Del. I don't have the Windows boot disk, I looked before posting this thread, so I can't do a windows repair. Is there any way around fixing this. Please advise..............Thanks
