Windows 7: Bootmgr.exe missing... mpio.sys missing or corrupted. Unable to boot

23 Dec 2013   #11

Windows 7 Ultimate x64

Some BIOS have where you set CD/DVD order, then another section to set HDD Boot Order, and there you then select CD/DVD first.

I am not sure what else to tell you. Try removing the Battery for 1 minute and then load up again.

Insert the CD/DVD, then reboot your computer. During boot, keeping tapping F12....a boot menu should pop-up giving you options from which device to boot.
