So I've just finished messing up my computer beyond repair. I originally had a Windows 7 install on my 64GB SSD and all my data on my 1.5TB HDD. So I decided to install Windows 8 Consumer Preview. I tried to clone my 64GB SSD onto my HDD; but that didn't work either at first. I later learned that it wiped all my data off of it. Thank goodness for the cloud. So I retried the cloning after I realized that my data was gone, and I finished it. So I rebooted and got a cryptic error message: BOOTMGR is compressed. Press Ctrl+Alt+Del to restart.
So I did. Several times. I followed the instructions to rebuild the bootmanager from many websites, including HowToGeek, smallvoid.com, and more. None worked.
BTW, I've lost my Windows 7 Professional DVDs. All I have is my Windows 7 Home Premium DVD. It's the one I got with my laptop.
How can I get back to a working computer? I'm willing to wipe anything, as my data is all in the cloud.
