Windows 10: Reboot and Select proper Boot Device or Insert Boot Media in the selected device and press a key
I think I installed a piece of old software and it messed up some of my W10 system files. Its school related software, I promise (Gene Runner) >.<
Symptoms: Locking up, computer becomes unresponsive. When attempt to reboot, I get that message above, right after BIOS screen. I can boot into regular W10 by pressing F12 during boot menu and select Windows Boot Manager. Once thats done, it'll boot s l o o o w l y into W10.
When W10 fully loads, it'll be unresponsive again. Some times, my hard drive will disappear from BIOS.
No weird noises from hhd (2 tb), it is not hot to touch, I hope it is ok.
Before computer fully loads and slips into coma, I can click on Windows logo... Restart (shift click) and run to Safe mode. From there, I ran chkdsk and tell it to fix; I also defragged my c drive and manually removed offending software (W10 can't uninstall it).
After chkdsk, computer seems to be ok. Whatever the errors, chkdsk fixed it. Computer is as responsive as before. However... when I reboot, it'll show that friendly Boot message again. I had to press F12 at boot menu and select Windows Boot Manager to get into my normal Windows desktop.
*Yes, I did opened up the case to make sure dust isn't an issue, no loose wires.
My Q is... how do I fix it?
I didn't have latest back up or restore point. Wiping out hhd is a pain... I like to avoid that if I can. I would like to put a SSD in it (clean install W10)... but unsure how to transfer my current OEM key (originally shipped with W8) to new disk and activate W10 with that. Any help is appreciated.
