Windows 7 cannot boot

[r3n3r4d3]

Hi all

I have a Gigabyte GA-MA770-UD3 rev. 1.0. My BIOS was version F4. I installed @BIOS, and updated the BIOS to F8 (Latest stable BIOS according to GIGABYTE). After BIOS finished updating, it prompt me to restart. So i did.

After i restart, the message "Missing BOOTMGR. Press CTRL/ALT/DEL to restart".

I tried to boot the windows 7 CD and used Startup Repair, but it cannot find any problems.

Can anyone teach me what to do please?

Thanks!
