Windows 7: Bootmgr missing...

Bootmgr missing... [Solved]

I spent the day trying to fix my operating systems boot.
Earlier in the day i tried to install a MacOSX (I've formated the second hard-drive asoff now) on a seperate hard-drive (CRIVE AKA Windows 7 drive was unplugged). After i was done i decided to plug in the c drive because i wanted to get on windows to setup dualboot. But for some reason it said bootmgr missing...
I've tried bootrec /fixboot and the other ones.


I just checked my drive somehow Cdrive turned in to D drive would that be the problem? Could somebody please show me a way to change from D drive to C drive?

If this would help nail the problem. Also tried to boot the hard-drive from my laptop via esata. I get a different problem i get a blue screen during the Windows seven loading screen. Heres the stop code: 0x0000007b.

regards.

I don't know what you have done wrong. If you really had the drive unplugged while you messed with MacOSX, then nothing would have happened to it. Just put everything back the way it was and it should work.

but it seems like maybe you formatted your Windows drive or you set the wrong partition as active??

you can do it using the diskpart tool on the recovery disk

for example

diskpart

list disk
select disk 0
detail disk
select vol 1
active

Hi and welcome to sevenforums

The 0x0000007b can be caused by a missing driver, which I suspect. The bootmgr might not have been located on C: for example if you had another OS like XP on the drive and then installed win 7, win 7 installs a folder called boot onto the xp drive. when you reconnect the drive it might not be able to find the folder. Merely changing the drive letter isnt going to help.

Could you tell us about what was where and in what order it was setup

Thanks

1. Partioned drive D (2nd drive) to Fat32 inorder to install Mac OSX.
2. Shut down computer so i could unplug C drive (O/S drive)
3. Began installation process (MacOSX leopard).
4. After completed shutdown to plug C drive back in
5. booted computer the error was "SYSTEM BOOT FAILURE"
6. Put Windows 7 disc in repair > command prompt > Bootrec / commands except the first one on the list i think it was bootrec /MBR (read somewhere it corrupts drives).
7. Same problem
8. Used Diskpart tool because when i tried to repair disc could not detect O/S
9. Ill try retrace my tracks on the stuff the did on Diskpart. At this point bootmgr missing appeared instead of SYSTEM BOOT FAILURE.


Is there a faster way to acessing COMMAND PROMPT rather then waiting avout 4-5mins for the disc to load - System specs Q6600, Gigabyte P35-DS3, Nvidia 8800GT, 2x1gig 800 ddr2 ram and 2x500gigs Samsung / Seagate.

Just done diskpart > list disk says

DISK 0 online 465gb 0
Disk 1 online 465gb 0

Right now repair cannot detect O/S

I'm guessing the easiest way to fix this without reformating my system is to assign the hard-drive back to c and reinstall the operating system, wouldn't it?

Wow....this really isant my day. At the install screen my display decides to blank out...

you didn't finish the steps with diskpart

shift + F10 is a little bit faster to get to command prompt on the Windows 7 DVD.
