Hi all! I'm new to this forum so bear with me. Last night, I started to compress my c: in windows through the properties window, but then decided to cancel it about 15 seconds after the process began. There were no problems until I tried to boot windows this morning and got the following error message: RUSJO is compressed Press Ctrl+Alt+Del to restart I am running a dual operating system (Ubuntu 10.10/Windows 7). GRUB is in place and gives me the option to boot Ubuntu or Windows. I can boot Ubuntu just fine (I'm using it right now) but whenever I try to boot Windows, I get the error message above. I've tried searching for ways to uncompress the c: from within Ubuntu, but no luck. Any one think they can help me out here? Pretty please?
