FAQ's
Q: What if I cannot switch between Legacy and UEFI or if switching does not help?
A: If you cannot manage to switch between UEFI and Legacy or it does not work, just skip that step and continue with the rest of the steps seen here in this updated video: [ Ссылка ]. What was the result of the Dell diagnostic scan?

Q: It says I can’t enable the legacy option ROMS with PTT enabled
A: Go into the Security Tab and try to Disable PTT Security. If that does not work, then skip that step, and continue with the rest of the steps seen here in this updated video: [ Ссылка ]. What was the result of the Diagnostic Scan?

Q: What key do you press to access the diagnostic test?
A: F12

Q: What if the factory reset does not work?
A: Newer computers are starting up so fast these days that the Factory Reset from the Startup menu is becoming more and more obsolete. In that case, skip that step and continue with the new install of Windows 10; [ Ссылка ]

Q: What if the Hard Drive fails the test?
A: If your Hard Drive fails the test, you will have to replace it. Then you would need to install Windows to the new drive as seen here;

You can make your own Install Media Free from Microsoft as seen here; [ Ссылка ]. If you cant create your own, you may have to purchase it. You can see an example of a good install media USB in the Repair Tools list here; [ Ссылка ].

Q: What if the test says the hard drive is not installed or not available?
A: That means its either bad or loose. I would first try 'reseating' the Hard Drive as seen here in this updated video: [ Ссылка ]. 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 examples of HDDs or SSDs you can purchase here in the Computer Component List: [ Ссылка ]
FYI: SSDs are faster and break less often :)
You would also then need to install an operating system onto the new one as seen here;

Q: What if changing the settings in BIOS didn't help and the scan passes everything?
A: If changing the settings in BIOS did not help, and the diagnostic scan showed all components to be healthy, then its most likely an issue with your operating system. Can you find any Restore or Repair options in BIOS? Or perhaps an option to Uninstall Last Update? If not, your last resort would be to reinstall the Operating System.

Q: The test says the battery is almost dead. Is that my issue?
A: If the test says your battery is dying, I would definitely replace it asap. However, that's most likely not the cause of your boot loop. To make sure, remove the battery and try to turn the computer on with only the power adapter plugged in. What happens then?
