Windows 7: Bootmgr is compressed

03 Oct 2012   #1

Win7 starter
Bootmgr is compressed

Hello, dear members

So, i've got a big problem. Yesterday, I tried to reinstall my windows 7 starter on my Acer Aspyre One AOA 150. I wanted to delete everything from HDD, but after, when I trying to restart, I meet this nice characters: BootMgr is compressed.

I read a lot of informations in this forum, but I can't solved this problem.

I prepared a bootable HDD from my TOSHIBA, and I changed the first boot to the USB HDD ( I don't know why can't I boot from SDD card.. ). When the boot is starting, it took a few seconds, and BootMgr is compressed, press ctrl alt blabla...

Without bootable HDD, the Windows Boot Mgr wrote: The windows boot configuration data file does not contain a valid os entry.

What can I do in this situation?

Hello Gotenson, and welcome to Seven Forums.

What's likely happening is that your external HD installer like the SD card installer rarely works well for installing Win7, so it is not booting and instead trying to boot your failed Win7 installation. Do you still need to access Win7 to rescue files or for any other reason?

If not I would write the Starter ISO to USB flash stick using Universal USB Installer with Win7 in dropdown menu.

Then boot it to wipe the HD with Diskpart Clean Command accessing the Command Line at first screen by pressing Shift + F10. After Clean command completes, close Command Box and proceed to Clean Install Windows 7
