I have a acer aspire 5000 and when i turn it on it says bootmgr is compressed, press ctl+alt+del to restart but it wont restart

The Windows operating system allows you to compress the files on your drive to conserve disk space. In some situations, this compression process will compress files required for the operating system to boot. Files that are compressed must be decompressed prior to execution. Since the operating system has not loaded, boot files cannot yet be decompressed. In this case, the operating system will fail to load and a "BootMgr is compressed" message will appear. An easy way around this problem is to boot from the Windows DVD, and use the provided interface to access your drive properties and decompress it.

Turn on the computer, and insert your Windows DVD. Press a random key on your keyboard once you see the "Press any key..." message. This interrupts booting from the hard drive and forces a boot from the Windows DVD. Click the "Next" button at the bottom of the Windows 7 dialog, and then click the "Repair your Computer" link Below. File Compression and Decompression Select the "Load Drivers" button at the bottom of the "System Recovery Options" dialog, and click the "OK" button on the "Add Drivers" dialog. This opens a file browser on your screen. Click the "Computer" icon, which is located on the left hand side of the screen. This displays an icon for your disk drive. Right-click your hard drive, and click "Properties. " This opens a Local Disk Properties dialog. Click to deselect the "Compress this drive..." option at the bottom, and then click the "Apply" button. Select the "X" icon to close the file browser window. This takes you back to the Install Windows dialog. Press the "X" icon at the corner of the Install Windows dialog. This opens a cancellation dialog. Select the "Yes" button on this dialog to restart your computer. Hope this helps

You need to format your Laptop or you can try replacing the Boot files from another Laptop.
You can try repairing your OS by booting the original disc.

Boot manager compreessed

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

My computer is asking for a boot **** and i do not have one so it tells me to contact system admin

for a boot what? bootfile? Well the bootfile is either corrupt in your HDD or your trying to change the operating system with a bad CD that is missing the bootfile. Last possibilty is you have a bad hard drive. I am just guessing because you didnt say what u were doing when it happened and all it says is missing boot****

BOOTMGR is compressed press Ctrl+Alt+Del to restart

Insert Microsoft Windows Vista Installation Disc.
Press any key when it says "Press any key to boot from CD".

After that you should see "Windows is loading files..."
KEEP pressing F8/F9(can't rmb which, just press both alternately) while
the progress bar loads..... Dun let go until you reach "Advanced boot
information" where you should see Safe Mode, Safe Mode with Networking,
Last Good known configuration etc...., just select Safe Mode with
Networking(or Safe Mode/Safe Mode with Command Prompt) and press Enter.
Wait for the files to load and there should be "Safe Mode" on 4 corners
of your monitor.

Just be patient and wait. A windows would soon pop up and says "Install
Windows". Don't worry, click next. Now at the bottom of this window, you
should see "Repair Windows". Click on it, and there are several options
available here. For this case, which is "Bootmgr is compressed.", CHOOSE
THE LAST OPTION - "Start Command Prompt".

OK type these things (Only works if you have Firefox, can't think of
anything else) below and follow closely:

When Command Prompt is started, type the command below first to ensure
that C Drive or whichever drive which contains all your system files is


X:System> (The string on the left is what appears on command prompt,
may differ on other computers.)

Now TYPE "C:" or "D:", depending on the hard disc volume you are





If you get this, very good, continue with the steps below.

Now Type:

CDProgram FilesMozilla Firefox



C:>CDProgram FilesMozilla Firefox (Press ENTER)

C:Program FilesMozilla Firefox (<<<<< Result)

Now type "firefox".

wait for Firefox to launch now.
it doesn't matter if no internet is available.

Now on firefox, go to File > Open File

Double click "My Computer", and you should see your hard disc there,
but don't double click on the hard disc. Instead, click once on the hard
disc, RIGHT CLICK, and choose properties. AT THE BOTTOM, UNTICK, I
REPEAT, UNTICK THE BOX SAYING "Compress this drive to save space

Read-Only Box and Archive Box), UNTICK, I REPEAT, UNTICK the 3RD BOX
Which says "Compress contents to save disc space".

Click OK, Apply and close the folder/file properties.

Now close the box opened by firefox, close firefox, close command

Your computer should be able to start properly now smile.gif

Boot Manager is compressed
If by accident having compressed the entire boot partition, then Vista will display the following error:
BOOTMGR is compressed. Press Ctrl+Alt+Del to restart
Check points for fixing compressed boot-manager:
* Boot into Windows Recovery Environment (WinRE) and perform a “Startup Repair”.
* If the above doesn’t solve the problem then boot into WinRE again, but when selecting the Vista-installation, then press “Load Drivers” (Instead of “Next”) and use the mini Windows Explorer to right-click the boot-drive and deselect “Compress this Drive” and choose Apply to sub-folders and files.
* If that also fails then boot into WinRE again, and go to the “Command Prompt” and execute these commands:
o compact /U C:ootmgr
o compact /U C: tldr

Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.

You can find lots of items about this problem on Google. Without more information such as your operating system and what happened before the problem started, it's hard to say any more. Try this thread for several possible solutions.

Bootmanager is compresed and booting is not preformed

Hi their Rak,

Basically, never compress the entire c: drive, ie, don't just right click the c: drive choose properties then check the box that says Compress drive to save space - Really! DONT DO IT - EVER! Especially if running bootcamp.

If you compress the System Folder it will screw up your bootup in Bootcamp, or from Fusion or even Parallels Desktop. If you want to compress your drive (which is a good idea), be selective about it. Go into your c: drive and compress only your Docs&Settings folder and the ProgramFiles folder. Anything other than the Entire 'Windows' folder. If you want to compress any of the Windows folder, again be selective and do any folder other than the System and System32 folders. Leave all files in the root of the Windows folder uncompressed.

When it happened to me (yeah! That's how I know!! Oops) the only way I was able to rectify it was to create another windows boot file in Parallels and uncompress it from that. After that it worked fine. Hopefully others can benefit from my experience.

All the best to the best of you all
