If I have my UML295 plugged into the computer when I try and boot it up, it wont start. If I unplug it and start it it works fine. I can even have it plugged in and when it hangs up unplug it and sometimes I can get it to boot up then. Is there anyone else having this issue?
You may have a strange boot priority setting in your BIOS that is telling your PC to try to boot from USB instead of from disk. If you are savvy looking around BIOS it might be worth a shot to check out your settings or even disable boot from USB.
