FAQ's:
Q: What are the buttons you press?
A: F2 - BIOS, F12 - Diagnostic Options

Q: What if I cannot seem to switch between Legacy and UEFI or switching does not work?
A: If you cannot locate the options to switch between or if switching does not work, then skip that step and continue with the rest of the video. What was the result of the diagnostic scan?

Q: It has an error saying 'legacy option cannot be enabled with PTT enable'
A: Disable PTT Security by going to the Security Tab, and selecting PTT Security. Uncheck the box. If you cannot locate the options to switch between or if switching does not work, then skip that step and continue with the rest of the steps in this updated version of this video: youtu.be/B2Umoh81QeI :) What was the result of the Diagnostic Scan?

Q: What if my diagnostic test shows the HDD as 'Not Installed"?
A: If the HDD is showing as 'Not Seen' or 'Not Installed' that means the hard drive is either loose or bad. I would 'Reseat' it (unplug it and plug it back in) as seen here in this updated video: youtu.be/B2Umoh81QeI. Try the scan again. If it still says that its not installed, then its most likely bad and needs to be replaced. You can see replacement and upgrade HDD's and SSD's here: amzn.to/430vkEz. To learn the difference between HDD's and various types of SSD's, view this video: youtu.be/KgDucEw7drA. Let me know if you would like any help with that :)

Q: My hard drive didn't pass the test. What do I do now?
A: If your HDD failed the test, then it needs to be replaced. You should then replace the hard drive as seen here; youtu.be/tNp5Kbo9uHg. You can see replacement and upgrade ideas here: amzn.to/430vkEz

Q: Changing the settings in BIOS didn't help and my HDD passed the test.
A: If changing the setting sin BIOS didn't identify the issue and your Hard Drive passed the test, then the issue is most likely Operating System related. Can you find any Repair or Recovery options in BIOS? If that did not help, I would next try to reinstall the operating system.

Q: I cant run the diagnostic scan. It wont complete or I cant access it.
A: If you cannot run the scan, we don't know for sure if the HDD is healthy or not. We will have to continue troubleshooting assuming it is for now. If its healthy, and if the issue is operating system related, I would then reinstall it.
