My brother has downloaded a executable file from Skin Pack — I believe it was the Mountain Lion IO6 skin pack. He's using an Acer Aspire 553G.

And now his operating system won't start (Windows 7).

It gets to the BIOS and then goes to load up the OS but the screen goes blank and it just goes back to the BIOS over and over again. He decided to play with the bootup settings and tried different options and got the error message "Operating System not found."

Does anyone have any idea how to solve this?

Right after POST have him hit F8 until he gets into the boot menu and try the "Repair Your Computer" option.

This won't work as the BIOS cannot find the operating system to begin with. –  DragonLord Oct 6 '12 at 23:46
    
Good point, throw the Windows 7 disk in the drive and boot to the System Recovery options. Try the Startup Repair from there. –  Mitch Oct 6 '12 at 23:49
    
windows 7 came with his laptop, he has no disk –  8BitSensei Oct 7 '12 at 19:22
    
Can he borrow one? –  Mitch Oct 8 '12 at 0:46
