FAQ's:
Q: I cannot find the options to switch from Legacy to UEFI or switching them didn't help.
A: If you cannot find the options in BIOS to switch or if switching didn't help, move on and continue with the other steps in the video :) What was the result of the HP diagnostic scan?

Q: The test showed my hard drive to be healthy and none of the other fixes helped :(
A: If the diagnostic test showed your HDD to be healthy and none of the other fixes helped, you would now try to reinstall the operating system. You can see those links here;

Q: The diagnostic test says my HDD is not installed or to check cables?
A: If the diagnostic test shows your HDD to not be installed, that means your HDD may be loose or bad. Try 'Reseating' the HDD first as seen here in this video. Try the diagnostic test again. If it fails to change the scan, I would then replace the HDD and install an Operating System to the new one. You can see how to do that here;

Q: I cannot access the diagnostic test and the other steps didnt help.
A: If you cannot access the diagnostic test, then we dont know if your Hard Drive (HDD) is healthy. We can then proceed, assuming it is. If the other steps in this video do not help, I would then try to reinstall the Operating System (OS).

Dude! You are the greatest! Spent about a week trying to self diagnose my blue screen and didn’t even think about reseating the SSD.
Problem solved!
Thank you thank you!!!!

You’re a life saver. My work computer was doing this and it turned out the culprit was a wireless mouse USB. Once I removed and restarted, it worked perfectly.

You saved my almost went to a technician before I tried the 'seating' technique that worked for me.
Thanks

I keep my Windows 7 PC on usually but decided to reboot it for a "fresh start" But it would not boot but, kept coming back to the window where you either boot normally or : "Last known configuration that worked" (something like that). Couldn't even get into safe mode. I thought it was the hard drive, power supply or motherboard. It recognized my secondary hard drive that had an old install of Windows XP and, in my desperation, I tried to boot from that drive but, no dice. So, I disconnected the power from that drive but, it still didn't recognize the OS on my boot drive. I searched Youtube and found your video. When one of your tips was to check the time in the BIOS, I noticed it was off by 3 days so, I changed the CMOS battery and, it booted. Thanks so much for your help.
