Vista - Vista Recovery Disc Hangs

I am getting an error when booting my computer. It says "BOOTMGR is
missing pres CTRL+ALT+DEL to restart." I read online that to fix this
problem I need to boot off the CD/DVD and select Startup Repair. I am
unable to do this b/c whenever I boot off the CD it goes to the screen
where it says "Select a Language", but then it just hangs. I cannot
use neither the mouse or the keyboard to select next. I only have a
Windows Vista Home Premium Express Upgrade disc, so I do not think I
can completly re-format (which I'd actually rather do).

Some quick background of the computer to help evalute the problem:
When I got the Windows Vista Express Upgrade CD, I was running Windows
Media Center on my 35GB WD Raptor Drive. Due to space problems I
installed the new OS (Vista) onto my other 250GB Seagate drive. After
I had Vista up and running I completly reformated my 35GB WD Raptor
Drive b/c all it had on it was the old OS (XP) features and files.
Thats when my Vista problems started. I got the error above and have
been trying to resolve it.

Can anyone help me with this issue?
