There are a number of possible causes for BOOTMGR errors, including the most common "BOOTMGR is missing" error message.

The most common reasons for BOOTMGR errors include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors an outdated BIOS and damaged or loose IDE cables

Anothe reason you might see BOOTMGR errors is if your PC is trying to boott from a hard drive or flash drive that is not properly configured to be booted from. In other words, it's trying to boot from a non-bootable source. This also would apply to media on an optical drive or floppy drive that you're trying to boot from. make sure there are no disks in cd floppy usb drives Test all power and data leads that attach to your hard drive IDE,SATA the leads from your ((MOTHERBOARD TO YOUR HARD DRIVE)) make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty if its a flat ribbon 40 pin IDE it will be the fist to fail Make sure all power and data leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty a computer needs Data and Power to travel through every working device and to continue its cycle and to have an end so any faulty leads will end up with a computer error. also make sure you have set it boot from you hard drive in BIOS Restart your computer and enter BIOS mode. On most computers this is done by pressing the Delete ot F2 key but will vary depending on your computers bios other keys Acer: - Ctrl+Alt+Esc , ALR PC: (F2) or (Ctrl)(Alt)Esc) , Award BIOS: (Del) or (Ctrl)(Alt)(Esc).

Scroll over to the "Hard Drives" tab, and make sure your computer has the hard drive assigned to be on. Often during BIOS you can select auto-detect or change options with your hard drive to make sure Windows can recognize it. Once you've selected your desired options, continue to boot. or The solutions might be very simply... remove your hard-disk and attached to other PC or laptop as an external hard-disk. When it is detected, go to my computer, right-click, untick that (stupid) option, immediately you see the message uncompressing and its done. Put your hard-disk back in to your machine its ready.. w7 insert your OS CD
go to DOS window and type in your OS driver (usualy C:/

type in bootrec /FixMbr
then type in bootrec /fixboot

then type in bootrec /rebuildbcd
then type in exit

restart your computer
it will work 100% only if you prompt at the same order Hope this helps. BOOTMGR Is Compressed b> 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. http://windows.microsoft.com/en-US/windows7/What-are-the-system-recovery-options-in-Windows-7 http://msdn.microsoft.com/en-us/library/aa364219(v=vs.85).aspx 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

Boot mgr is missing


Boot Manager is missing If the boot partition no longer can be found, then Vista will display the following error: BOOTMGR is missing. Press Ctrl+Alt+Del to restart
The Windows Boot Configuration Data file is missing required information
More Info MS KB 919529 More Info MS KB 927391 Check points for fixing missing boot-manager: Check that your boot device is configured properly Boot into Windows Recovery Environment (WinRE) and perform a "Startup Repair". 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 OR maybe try this first. 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: compact /U C:\bootmgr compact /U C:\ntldr If you for some strange reason have lost your Vista DVD, then you can also use a Windows 2000 / XP install CD and enter the recovery console instead and execute the following commands: attrib -c c:\bootmgr attrib -c c:\ntldr


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.

Help my toshiba showing me bootmgr is compressed


Hello.

Your system files are corrupted.

Boot your system to Safe Mode (press F8 repeatedly). Go to System Restore and choose a date when your system worked OK. Note: with System Restore, everything, including your documents and other files you saved on the hard drive, will roll back to that date.

Hope this helps.
