BootMGR is Compressed.
boot into Repair,
but after selecting the Windows 7-installation, press "Load Drivers" (Instead of "Next")
and use the mini Windows Explorer to right-click the boot-drive, select Properties,
deselect "Compress this Drive" and choose Apply to sub-folders and files.

Its very easy to fix bootmgr compressed error

Insert the windows 7 disc if you dont have original disc no problem borrow it from your friend. Now boot from your disc, When you see windows instalation "Start" screen see below a link for Repair your computer. Your computer will scan your hardisk for installed windows. Once it done click on "LOAD DRIVERS" and it will open up like explorer. Goto "My Computer" and search for BOOT hardisk partition. Check all drives property and see if they are compressed. Simply UNCLICK and press apply and ok. Once its done, restart yoir computer and eject your windows 7 disc. Problem is solved. :)
