windows 7 ultimate 64
Boot mgr is missing press ctrl +alt+del to restart

i am a newbie as far as computer hardware is concerned. after struggling for days to install windows 7 onto my new pc which came without and 0s installed,
specs are:

hp pavillion elite
amd phenom 9500 quad core
4gb ram
1tb hard drive ( comprised of 2 500gb hard drives)
note 1 of them i made a partition of 30gb where i installed the win 7 OS the rest of the 465 used as storage for my files.

the other 500gb i left untouced which on disk management is unused incase i do decide to dual boot a mac os on that one.

i was using my computer for almost 2 days installing all my files and softwares etc when suddenly it shut down on me and when i tried turning it on it said

Disk boot error please insert system disk and press enter

i tried changing the boot order in the BIos
open the cpu casing unplugging blowing and re plugging the cables to the hard drives in.
however on the bios both hard drives are listed and wen i check status says that they both okay

i tried booting using the installation disc trying start up repair no luck with that
went into command prompt option
tried typing in
diskpart (enter)
lis vol (enter)
it list the 465 which i use for storage but the 30gb where the 0s is installed dosent show. surely if the hard drive had a problem the 465gb wouldnt show as it an te 30gb makes up te 500gb?

i tried
selecting the 465 volume enter and then exiting diskpart
then it says


so basiclly i have read almost all forums concerning this and followed most of the steps listed above for however mine says boot manager missing or corrupt, wen ever i run start up repair its says

start up repair cannot repair this computer automatically.
sending more information can help microsoft create solutions.

please do help me out as i have seen that almost everyone you helped so fars problem has been solved.
