Bootmgr control atl del (vista recovery won't boot)

I purchased the Vista recovery disk, I have made a disk that is usable on other computers, I changed my boot options to cd/dvd to boot first. I uploaded a copy to my external hard drive and a Sandisk memory stick. Nothing is working, I have followed all the directions from other forums and I am becoming so frustrated. Every time I turn my laptop on the disk will not boot and the dreadful BOOTMGR thing comes on, the computer will turn off after about 5 mins on its own. When I tried to boot from the external hard drive it shuts off. I can't boot in safe mode because some function keys are not responding. I have taken the battery out, unplugged and held the power button several times and no luck. I have an Hp pavilion 2945se. Any ideas? thank you
