Windows 7: bootmgr missing error, became bootmgr MISSING.

03 Jul 2011   #1

Windows 7 Ultimate 64 bit
bootmgr missing error, became bootmgr MISSING.

I compressed my entire C drive. When I rebooted I got the error "Bootmgr is compressed"

I don't have a optical drive, so I made a bootable USB drive using YUMI 0.2.3 and added the windows 7 recovery ISO. The USB drive boots and I can enter the recovery console, etc.

It couldn't auto-repair the problem so I tried enterinng the following in the command prompt code:

expand bootmgr temp
attrib bootmgr –s –r –h
del bootmgr
ren temp bootmgr
attrib bootmgr –a +s +h +r

I guess "ren" didn't work or something, because now the error is "Bootmgr is MISSING".

Still, the recovery disk cannot auto-repair.

i tried entering the following in the command prompt (from bootable USB):
bootrec /fixboot

It said the operation has completed successfully. I took the USB drive out and rebooted. bootmgr is still missing.

I also tried:
bootrec /rebuildbcd

Total identified windows installations: 1
Add installation to boot list? yes<y>no<n>all<a>

I selected yes, it said "The requested system device cannot be found".

On that note, I am stuck. How can I restore bootmgr?

If you now have the drive uncompressed.

Boot up using the Startup disk CD or Windows 7 DVD. (not the OEM manufacturer's Recovery Disk) If you have a Netbook, needs to be on USB Pendrive.

Do a Strartup Repair:
Startup Repair
Note: You may need to do startup repair 3 to 4 times.
