Hi all

 My old PC has no USB on the Bios and the CD drive is not working. I have "Bootmgr is compressed". Can I put the HDD concerned into another PC running XP and not win 7, and repair the fault with the Win 7 CD ? I also have a seperate enclosure on my XP PC.

Hi

 

A " BOOTMGR is compressed " message is usually caused by a combination of the below reasons.

 

1. There is no hidden 100 MB "System Reserved" partition in the machine. If it exists, Windows will always use it as the "Active" partition and store critical boot file in it. Usually this small partition is only created if you do a clean install of Win 7 - re-partitioning the disk. If the disk is already partitioned in an earlier version of Windows, installer will simply installs the "Bootmgr" to "C:".

 

2. You compressed "C:" which in turn compressed all files including "Bootmgr". The bootstrap code which is used to start Windows don't have the capability of decompressing  files. As a result the bootstrap code will present you the error message.

 

Please try the below steps.

 

:step1: Connect the HDD as a slave drive ( USB enclosure/direct connection ) .

 

:step2: Identify the drive letter of slave drive's Windows partition. For our example , "E:".

 

:step3: Open a command prompt and type the below commands one by one.

 

      attrib -s -h e:\bootmgr

 

      compact /u e:\bootmgr

 

If the above steps shows any error messages, post the exact messages or screenshots with next reply. Also a screenshot of "Disk management" window will be helpful.

Before I attempt this Anshad, do I type in the first command and enter. Or type in both commands then enter?

Hi

 

You should type the first command and press "Enter" key to execute it. Then run the second command.

Hi Anshad

Thanks for prompt reply. Just getting "access denied" at the moment. Could that have something to do with me being administrator?

Hi

 

If you are doing this from a Vista or "Win 7" machine, you should enter the commands from an elevated command prompt.

If OS is "Win XP" and you are getting the "Access Denied" message, you should decompress the drive. To do that, deselect the option to compress in drive's properties.

thanks for anshad.just running the disk on XP for error checking. so you say that simply unchecking the compress box will automatically decompress the disk?

Yes, in most cases. Decompressing the drive will hopefully decompress all boot critical files. After successfully decompressing, refit the HDD to your laptop and try to boot.

Disk is in enclosure. Opened properties and unchecked compress, clicked apply and nothing happens.Yet if I click compress then apply, I get the window with options for compressing f: or all. Its almost as if f: isn't compressed at all.
