compressed boot manager in windows 7 (problem and solution )

by rohitjainnasik / May 12, 2010 11:46 PM PDT


when we compress the disk space entirely by going to my computer --> right click on the c:\ drive icon ---> properties ---> compress disk drive, the compression utility in win 7 accidently may compress the boot manager files that include the file bootsect.bak and the \ boot folder also . when the computer is restarted the machine hangs up and says "boot manager is compressed " and shuts down .


sadly the startup repair option or any other repair option in windows 7 startup recovery failed to solve this problem. this can be solved by

reboot your pc

select the repair your computer option

command prompt

at the prompt type notepad (since the recovery option boots from a seperate wim image it has notepad built into it )

press ctrl + o which invokes the open file dialog

go to the open file field (ALT+N) and type c:\boot and also see for the c:\bootmgr
file. right click it and deselect the option of "compress files to save disk space"

when we apply the boot manager is again decompressed. also if someone finds this harder we can directly deselect the compression option by reversing the process used to compress the drive

thats it . we are done

Fastest solution - fixed in 15min

1. Download Active@ Boot Disc, and burn iso file to the disc.
2. Run Active@ Boot Disc
3. Open My Computer > Properties >> Untick - compress this drive to save disc space
4. Remove Active@ Boot Disc
5. Reboot normally.

Once you've done that, reboot after removing active boot disc cd.
Your computer will boot normally.

That's it. ENJOY
