Duh moment - I right-clicked on my C-drive properties, and selected 'compress drive to save space', and it actually did it! Yes, even the Boot Manager. Now I try to boot up, and only get a DOS prompt that says 'BOOTMGR is compressed - Press Ctrl+Alt+Del to restart'. I can't boot to my W7 disk. Not sure what to do now - any ideas, my genious friends?
Thank you in advance,
