Bootmgr is compressed

[kahlil88]

My friend decided to enable drive compression and after a reboot, the thing won't start because bootmgr is compressed. I have tried booting from the Win7 disc and running startup repair, as well as manually running bootrec with the fixmbr, fixboot and rebuildbcd options, the latter of which reports "0 windows installations found" although all three operations report being completed successfully. I also tried the "load driver" option just so I could browse the filesystem and disable compression, but it still stops with the same error on every boot.

The "base" windows files, BOOTMGR (and probably the BCD ) must be UNcompressed.

Anything you did had nothing to do with the compression of the file.

You need to UNcompress the BOOTMGR.

The COMPACT command should be available once you have booted from the Windows 7 install disk (which is a kind of PE):
