Vista - Vista Dual Boot Turned Missing BootMGR Turned Complete Horror

My services were offered by my father to a guy to install a dual boot on his system. I have done this procedure before so I felt fairly comfortable doing it on a system belonging to a business. However, mid dual boot procedure I start recieving BootMGR Missing Press Ctrl + Alt + Del to reboot. Immediatly I hit google; however, all given solutions prove to be negative in fixing.
The gentalman was supposed to have backed up his system for me, the words out of his mouth are "I'm doing as we speak". Vista came preinstalled so I have no Vista Home Premium x64 disks. So, I call up the guy and he says somethings came up and he couldn't make them but what ever I do make sure I get vista working again, don't lose his stuff.
Now it's forget the dual boot just get vista back, but this damn BootMGR won't stop popping up. I'm at a loss of things to do.

Hello Aaon, and welcome to Vista Forums.

You might see if running a Startup Repair on the drive Vista is on to see if it can repair the boot MBR file for it.

Hope this helps,
Shawn

Sadly I have tried this as well as going through the console and trying to repair it manually.

have you done this at the command prompt when you boot from the disc bootrec.exe/fixmbr and bootrec.exe/fixboot

yes and yes
