I tried changing drive letters with the newly purchased Acronis Disk Director Suite and now my pc won't even boot!!!! the main operating system (Windows)was on the L drive and the boot (system) file was for some strange reason on the C drive after I had to reinstall windows about 20 days ago. So I decided to make the L drive C and the C, L. Acronis rebooted the system twice before supposedly changing the drive letters and now I'm stuck with the welcome screen to windows (The blue one) but no way to log on!!! HELP!!!!!! I need my pc!!
