I'm new to these forums and I think this thread is in the correct category, if not please direct me to the appropriate category.

Okay so regrettably I compressed both partitions of my HDD (Including Recovery) only to be extremely shocked by the message "Bootmgr is compressed, press CTR + ALT + DEL to restart" I have never come across this issue before so I decided to do some research, I believe in order to resolve this problem I needed to decompress the HDD however I do not have the Windows 7 installation disk nor the iso files for it + for some strange reason I was unable to download it. I have tried several Windows 7 repair disks, booting from both DVD and USB with no success, the screen simply goes blank with what appears to be a flashing underscore, after several minutes of reading the disk/USB it will revert to the previous "Bootmgr is compressed" message (Note: I am using Windows 7 32 bit Home Premium and had the appropriate recovery disks). While this is all happening no other options/messages appear.

Any help will be greatly appreciated, thanks in advance!

Hello Whoppaahh, and welcome to Seven Forums.

You might see if this may be able to help. Step 2 would apply to you since it's not booting from the DVD or USB normally.

Thanks for such a quick reply. Regardless of whether or not HDD,USB or DVD are the highest priority in BIOS, repair my system is not an option, it simply is not displayed. When attempting to boot from either DVD or USB a flashing underscore appears for several minutes and then the bootmgr is compress error is displayed once again.

Were you able to boot to your boot menu (ex: F11 and not BIOS) to select to temporarily boot from the DVD or USB instead?

Yes, I believe it's F12 on my laptop if that matters. Although I'm able to access it, selecting DVD or USB has the same outcome as booting from them in the BIOS.

I eventually managed to solve this by copying the WinRE files from another PC running Windows 7 64 bit to a bootable USB. Although the repair my computer wasn't compatible with my 32 bit, I was able to select the option Load Drivers and decompress the HDD that way.
