I ran Partition Magic 8.0 to resize a partition on my computer. When it was done with the process an error message appeared and below it was the instruction "click any key to reboot". I clicked and the system now will not reboot. It goes to a dos screen that gives me the option to boot normally, last known good config, safe mode, etc. No matter which option I try the system brings me back to that page. It happens when I powerdown and unplug the system as well. How do I get my computer to reboot? Thanks for the help!
