I owned as my Primary computer a HP a6119h, Today I went and bought a MSi NF750-G55. A AMD Phenom II 955 Black 3.20Ghz and 3Gb Patriot DDR3 12800 Memory 3x1Gb.
When I boot up I get a "BOTTMGR is missing. Press Ctrl+Alt+Del to restart"
Since it was from a HP PC I don't have a Windows Install CD, wheat do I have to do to boot to windows?
--> Could not check to see if this was valid hope the file is still there.
You need a program called bootsect which is on the Vista installation DVD which you don't have. That specifically puts BOOTMGR back onto your Hard Drive without touching anything else. However to run that you need to boot into some kind of Microsoft operating system.
Here's the bootsect tool from Windows 7 RC1, it's the same as the vista one http://rapidshare.com/files/269611722/bo… to use it type "bootsect /nt60 SYS /force" into a administrative command prompt.
