"Boot Device Not Found (Hard Disk 3F0)" on HP Laptop – Any Fixes?
Quote from AlexR on January 14, 2026, 2:39 pmHey, hoping someone here can help.
I’ve got an HP Pavilion Gaming 15 laptop and I’m getting this message on boot: “Boot Device Not Found Hard Disk 3F0”
Now it won’t boot into Windows. Just goes straight to that black screen with the error. I haven’t dropped it or anything and I haven’t opened it up either. Not realy sure what I did wrong. I’m freaking out a little because I’ve got some important class projects saved on there 😓
Can anyone explain what this means and if there’s any fix? Do I need to take it to service or is it something i can troubleshoot myself?

Quote from DataNerd on January 14, 2026, 3:21 pmThat hard disk 3f0 boot device not found error on HP laptops is pretty broad, and no, it doesn’t always mean your computer is dead. Most of the time it’s one of these:
-The SSD/HDD has failed.
-The connector to the drive got loose somehow (common in thin laptops).
-There’s a fault on the board, not as common, but happens.
Easiest thing to check first: get into BIOS and see if the drive is even showing up.
Power it on and start tapping F10 to enter BIOS then poke around under Storage or Boot Options or wherever it shows your drives.

On this model you should hit ESC firstt after powering it on not just F10. That brings up the startup menu and only from there you can press F10 to enter BIOS/UEFI.
Heres a video that shows the exact steps https://www.youtube.com/watch?v=O4NL0a4fbwE
I had the same boot device not found hard disk 3f0 error issue on my HP laptop and what fixed it for me was going into BIOS, changing the boot system from UEFI to Legacy, then restarting. That solved it. Try that.

Quote from em_on_pc on January 14, 2026, 4:24 pmDataNerd is right that boot device not found error can happen for a bunch of reasons and it’s sometimes hard to pin down. But if I were you I wouldn’t rush to take it to a repair shop unless you’ve got money to burn. I had a similar issue a while back and in my case the drive wasn’t dead but got corrupted.
What I ended up doing:
- Pulled the drive out of the laptop
- Hooked it up to my PC as a secondary drive
- Used Disk Drill to scan it and recover the files I needed (it didn’t show up in File Explorer so I couldn't just copy/paste my way out)
- After that I just reinstalled a fresh copy of Windows 11 on the same drive and copied my files back. Been using it ever since with no issues.
Not saying your case is exactly the same, but just know this is something you CAN do yourself if you’re comfortable opening the laptop.

Quote from AlexR on January 14, 2026, 4:43 pmThanks for the video @bryan . I followed it and switched to Legacy Boot just like you said. Got into BIOS fine. But unfortunately still no luck. Windows won’t start, and I’m still getting the same hp boot device not found 3f0 message on every boot. Maybe I'm doing something wrong,.

Quote from AlexR on January 14, 2026, 4:45 pm@em_on_pc thanks for the breakdown. That actually does sound doable, but I’ll need to find another computer to use first since this is my only laptop. Kinda hoping it’s not some major HP laptop hard drive problem, but if I can just get the files off it and do a clean Windows install like you did I’d be okay with that too.

Quote from bryan on January 14, 2026, 4:49 pm@alexr Hmm okay. Try to go back into BIOS and look for boot priority list to change the boot order. Make sure your internal drive is actually at the top.
Sometimes after switching from UEFI to Legacy, the boot order defaults to network boot or something useless. That can cause the black screen on boot or that 3F0 error to stick around.
If your BIOS not detecting hard drive at all then yeah… we might be looking at a dead (or maybe just disconnected) drive. But if it IS listed try bumping it to the top of the list, save changes, and reboot.

Quote from DataNerd on January 15, 2026, 11:13 am@bryan, my bad. haven’t touched HP laptops in a while. HP’s been a mess lately, especially with their gaming lineup. I don’t know what they’re doing over there. Half the time it’s weird BIOS behavior, the other half it’s overheating or SSDs dying young. I’ve seen way too many HP Pavilion and Victus systems come in with either boot issues or thermal problems.

Quote from OhioTom on January 15, 2026, 11:16 amI’ve got a HP Envy x360 and I’m dealing with the same kind of weirdness. Laptop works fine at first no issues at all but then about 10 minutes in I get the boot device not found on hp hard disk 3f0 error out of nowhere. I shut it off -> power it back on and it works again like nothing happened.
I tried getting into the UEFI/Legacy settings to change boot options but now the laptop stuck in BIOS. Is there some kind of BIOS reset I can try without pulling the whole thing apart ???

Especially that it works for 10 mins and THEN throws the hp boot device not found hard disk 3f0 error. Sounds like the SSD might be flaking out when it heats up(?)
As for the BIOS thing you can try a reset without opening it up. I’ve done this on a few HPs:
- Turn off the laptop completely
- Unplug the charger (this is important!)
- Hold power + F6 fo at least 30 seconds
- Then just power it back on
That combo basically clears out weird firmware states (HP doesn’t talk about it much but it does works) might at least get you out of the BIOS loop.

Quote from DataRecoverExpert on January 26, 2026, 2:55 pmJust adding this for anyone dealing with the same issue. Our team sees this boot device not found error pop up a lot, and these are the most common causes we’ve run into:
- Your BIOS might be trying to boot from the wrong drive. If the Windows drive isn’t first in the list, the system won’t find an OS and throws the error. Easy fix: check your boot sequence in BIOS and move the correct drive to the top.
- Corrupt boot sector or partition table. Even if your files are fine, if the bootloader is broken the system can’t start. Tools like bootrec or bcdboot can usually repair this from a recovery USB.
- Physical damage/loose connection. Sometimes it’s as simple as a loose SATA or NVMe connection. Other times the drive is starting to fail. If your BIOS can’t see the drive, this is a good place to look.
- Sometimes your PC doesn’t boot simply because the partition with Windows isn’t marked as “active”. Not super common, but it can happen after messing with partitions. This can be fixed using the diskpart command from a recovery environment.
We go over all of these (plus more) in our full step-by-step guide here, with screenshots and tips to walk you through each fix. Worth checking out if you're stuck in BIOS or seeing black screen on boot.
There’s also a video version of the guide right at the top of that page if you don’t feel like reading too much.

Quote from Ryan404 on January 26, 2026, 3:10 pmIf your drive still shows up in BIOS, that usually means the bootloader's messed up. You can fix it with the bootrec utility, but you're gonna need a flash drive first.
Just grab another PC and create a Windows 10/11 installer USB. Microsoft has an official tool that makes it easy, here's the guide and download link straight from them: https://support.microsoft.com/en-us/windows/create-installation-media-for-windows-99a58364-8c02-206f-aa6f-40c3b507420d
Once you’ve got that USB set up, plug it into your laptop, boot from it, go to Repair your computer > Troubleshoot >Command Prompt and run this lis of commands:
- bootrec /fixmbr
- bootrec /fixboot
- bootrec /scanos
- bootrec /rebuildbcd

Quote from AlexR on January 26, 2026, 4:05 pm@bryan dude… YES, that actually did it!!!!🙏
No idea how, but after I followed your steps exactly: shut it down, unplugged everything, held down power + F6 for a good 40-60 seconds… turned it back on and no more error!! It just booted straight into Windows like nothing happend.
I was stuck all day and had basically accepted that I was gonna need to take it to a repair shop. Huge thanks. I’m gonna copy all my important stuff to Google Drive now just in case, but for the moment it’s running totally fine.
Appreciate the help more than you know You might’ve just saved my **ss 😅😅😅
