HP Pavilion stuck in BIOS update loop
Yes unplug the USB devices for now. The system will automatically search USB devices for BIOS updates and diagnostics, so I would recommend unplugging so nothing can interfere with the regular process.
You might be able to get it to go into Windows by pressing F9 when turning it on. If you get a menu when doing this, choose Windows Boot Manager and it should start up. Not sure if this will work, but it’s worth a shot.
Failing that... it might be better to just load the update manually. Seems like it may not have downloaded properly and is now stuck.
What is your model number or product number? You can find both on the bottom of the computer. Model looks like Pavilion 15-0000xx (may vary), and product number looks like ABC12DE#ABA (7 characters + sometimes # and 3 letters). Do not post serial number (which is 10 characters long).
You can look up any of those three on HP.con (model or product in search, serial on the support page) and probably find the BIOS update, but if you’re not absolutely certain, then post the model or product number so I can double check. I mention this because the wrong BIOS can permanently damage the system.
Depending on whether you were able to get into Windows, you can do the update from there, or if not, you can use a USB stick to do it (you’ll need a blank one, size doesnt matter)

Before I start describing my problem, I'm not exactly the most tech savvy person so I might ask a lot of questions. Also I'm on mobile, so apologies for formatting.
Basically, tonight I hit update on the Pavilion and it said it was running through an important system update on the HP logo screen, after which it flashed the whole HP BIOS update screen, and then failed with a message of 'bios image file specified did not pass validation'. Then the screen turned black, and opened up to the screen with the HP logo, saying that it was installing an important system update again. It then went to the BIOS update screen, failed, and went back to the HP loading screen. This process happened one more time before I started panicking, and the next time it came to the BIOS update screen, I hit 'postpone update'.
When I hit postpone, the screen turned black. Then it went back to the HP logo screen. Then it went back to the BIOS screen and failed. The next time, I chose cancel update. It looped again. Even choosing to apply the update loops it. It's been looping like this for god knows how many times. Now, whenever it reaches the HP screen with the system update message, it turns black and makes a noise like screeching metal, then a groaning sound, then it opens up this black screen with a blinking white dash and goes back to the BIOS screen.
If it helps, it always makes that groaning noise whenever I have to force shut it down with the power button. Also, my laptop's done this whole BIOS update fail before, only previously it looped twice before resolving itself and just shutting off. It's also been faulty since the beginning- everytime I updated it, it would always be really slow and now this. I rely on this laptop for everything, especially for school, so any help would be greatly appreciated. Thank you very much in advance.
EDIT: More details if it helps but I have a USB cable splitter and another moniter plugged in to it at the moment, should I unplug those?
UPDATE: Left it for the night and woke up to the HP screen, interrupted periodically by the laptop shutting itself off and turning on again to the same screen. Is it at least safe to shut off?
