Windows 7: Corrupt Boot File

Hello Everyone,I am a new member.\

I have Vista Home Premium 64 Bit and Windows 7 64 Bit. As you see I am dual booting. I had Vista installed first.I installed Win 7 later.Everything was fine.
I installed cuipid a program that monitors,memory,CPU,etc. on Win 7. I used the PC aftyer that for a couple of hours.I shut doem,the next day I booted up went in to Windows 7(set as Default). It was fine.I resarted and arrowed to Vista to boot into Vista.
I got a Black sctreen saying: Windows failed to start. Hardware or software change may be the problem. I went into 7 and restored the system back to before I installed Cuipid,No Luck.
The screen that comes up when I try to boot into Vista says:
1 Insert windows Disk and restart.
2.Choose your choose your language and click next.
3. Click repair your PC./

I tried a repair on Vista and &.

On the page I also get error: File/windows/system/32/Winload exe.
Status: Qxc000000F
thenselected entry could not be loaded because the application is missing or corrupt.

I know thetre is a way to restore the Boot managwer from Cmd??

I would appreciate it if anyone could advise me how to restore the Boot Sector.

I have 2 hard drives both partioned.

Thank You in advance for any help.

You could try to open the cmd prompt and try these:
bootrec /fixMBR
bootrec /fixBoot
bootrec /rebuildBCD
bootrec /scanOS

Or you could try EasyBCD it easy for you to define start-up settings and edit boot entries on the new Windows manager.
Hope this helped
