How To Fix Dell Boot Loop, Stuck on Diagnosing PC, Stuck on Loading Screen

Use this video to troubleshoot and repair why your Dell is in a Boot Loop situation, stuck diagnosing PC, stuck loading or repairing, or other boot up issues. Make sure these are happening AFTER the initial Logo Screen. Please note, this can also be caused by a loose HDD. Try unplugging it and plugging it back in! That is called 'Reseating' the HDD.

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'

Q: What if my diagnostic test shows the HDD as 'Not Installed"?

Q: My hard drive didn't pass the test. What do I do now?
You would also then need to install an operating system onto the new one.

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.

I'm trying to move the easier hardware stuff there so that I can focus on the more in depth troubleshooting and diagnostic videos here :)

Dear Sir, you are the kind of people that the world is craving for. Thank you so much.

Brother, my Dell laptop developed the same problem you described here. I took it to the experts at a couple of computer chain stores and not only were they unable to fix, I was told that my data was lost and it would require additional expertise and money to recover. I went home and on a last ditch effort came across this video. And after following step by step your clear instructions, I was able to access the computer files, saved them on an external hard drive and now I am watching your other videos to see if I can fix what’s causing the problem. Bottom line: YOU DA MAN! Thanks!

This really helped me, although my laptop says: Hard drive test was unsuccessful, I exited the scan and rebooted. It started up. Thank you so much. Don’t know why this happened, but it worked. Thanks again.

You helped me just fix a computer that I thought I had messed it up for good, thanks for the help !! Genuinely appreciate it

This video saved me a lot of time and aggravation. My PC came back from a Dell Repair in Secure Boot mode. Once I followed the steps and set the BIOS back to legacy mode, my PC booted up normally. Thank you!

Your video made me realized I haven’t installed my Internal HDD properly, you mentioned “make sure to put the HDD on top” made me look for my Internal HDD and have to plug it properly. Thanks!

Thank you so much, had been trying for months to fix my dell laptop stuck on dell logo for 15-20 min. each time I turned it on. Diagnostic found no problems. Did the F2 when restarting laptop. The time was correct. Went to boot sequence, my hardrive was in second place, put it in first place. Laptop has been booting within seconds now. So so happy.

[scottlytlesr.]

Thank you so much, I was ready to take my dead PC to a repair shop. Your instructions were very clear and helpful.

[mommylife]

You just dont know how you saved my laptop now. Thank you for this video 🙏

[andreahill]

I found u to be very thorough and not confusing. U broke things down so well that just from prescreening the video i could easily carryout the tasks without having to refer back to the video . Ill let u know how it goes

Was stuck in the diagnostic testing loop. I switched from UEFI to Legacy. Then rebooted. It still took me to diagnostic testing. Rebooted. Spammed F2. Switched back to UEFI. Rebooted. It worked.

Thanks!

[marksmith]

This video is so good that my computer started working as soon as I started watching it. Wow!

[wolfmonsteridk]

Thanks man I was trying to fix up a laptop. My uncle gave me when he passed so thanks

[richard]

Thanks for your quick response! I kept poking around after I posted my question and discovered the surprisingly mundane problem and fix. I tried starting with all periphials unplugged (I hadn't done that before) and it started! To cut to the chase, the problem was a stuck Control key on my keyboard. Pried it up with a knife to unstick it and all was fine.

You are the man! The boot sequence had gotten messed up, and your video helped me fix it! Thanks a ton!
