From a failed HDD to me forgetting to unplug my USB drive or left a CD in the tray.
Start with easy stuff. Open the DVD drive and unplug all USB things.
Running windows 10 on dell desktop. After my computer sits awhile. A screen comes up that says no boot device available. press enter key to retry. I push enter and same thing keep popping up? The busy light stays on all the time. I have to shut off the power and start over again. Any suggestions? Thank Yoiu
