"Bootmgr is 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: c: 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?
