SOLVED Windows not installing

[CrayZE]

So, I'm trying to install windows off a USB iso. Problem is, whenever I try to boot to the drive, it says "BOOTMGR MISSING press CTRL ALT DEL to reboot" Am I doing something wrong? Please help.

MSI z97 Gaming 7 mobo
Kingston 120 GB SSD

RESOLVED - it was the software I was using to install the ISO. Its working just fine now.
