my laptop came with windows 7 pre installed, i was playing a video game, and windows 7 crashed, tried to reboot, and got the message "bootmgr missing", so i tried to run the windows repair, and half way through the windows repair, it did one of its shut
downs that it says may happen. and when the system booted back up i got the message "No operating system found", is there anything i can do to restore it? i do have a computer with a preinstalled version of windows 7 as well, can i put that on a flash drive
somehow and put that on the laptop?
