I have an HP Z840 running Ubuntu 18.04. I recently rebooted the machine after having some issues writing to the main HD and now I get a “BootDevice not found” and hard drive 3F0 error. I tried to boot with a USB and a Ubuntu iso image so that I can at least try to recover some files, but that just leads me to a black screen with a blinking underscore.
I suspect that the machine has some issue with a HD, but that shouldn't prevent me from booting with a USB, right?
At this point, I'm kind of stuck so any help would be greatly appreciated!
SOLVED::::: I also had the same problem and managed to fix it. It has nothing to do with electricity in your computer. Just make sure the boot options match with the ones on your computers boot options.
On my case i had booted ubuntu in GPT with UEFI without CSM but on the computer my boot options were set to UEFI with CSM. The solution was for me to change my settings to UEFI without CSM in my computer
To do: power off your computer then power it on then press (f10) to go to bios settings and go to bios options and scroll down untill you find the legacy,UEFI WITHOUT CSM AND UEFI WITH CSM..switch to UEFI without CSM and restart your computer and it will be okay.

RE: USB boot, HPs are very finnicky with getting booted. Your disk needs to be in the right format and you have to get a boot menu to select the drive proper to boot too. I had this problem trying to boot Ubuntu on a stick, and ended up going old school with a DVD drive.
RE: The Hard Drive
If you're getting read/write problems, unfortunately you are hosed. The drive is already dying.
The best bet is to try to access the drive from a live env and try and recover what you can, then replace the hard drive in the system. Hard drives die for all sorts of reasons, and there's no way to really diagnose it or repair a dying drive.
Same problem here. Installed 18.4.4 at an old HP prebook, via USB, to a brand new SSD and replaced the original Windows HDD. HP won't boot from the SSD. Had to change boot option from "UEFI with CSM" to UEFI without CSM". Moreover, while booting the laptop keep flashing black screen, had to press "ESC" key until it shows a menu that can select "F9 Boot Device Option", in there there is a "ubuntu" option, then everything works boot from there. Unfortunately every time reboot had to press esc go into boot device option to select. But it kind of works.
All other advices from YT/Google about bad cable, bad SSD, boot order change, Legacy support, etc. are not matter.
Pretty sure it's HP's BIOS issue, but anyhow it's a workaround.
