Use a separate Windows system to download the correct bios-update executable for your system from the HP support site. The solution is based on this HP support answer, the HP docs for creating a bios recovery drive, and a bit of trial-and-error with fingers crossed. Note that this does require another windows pc to open the bios-update executable, but there is no need to install windows on the target pc, nor do you need a windows recovery disk or windows-pe or any such thing. Here's what I did to update the bios on my HP x2 210 G2 running only Ubuntu 20.04 LTS. Reboot the computer and go into the BIOS (usually by pressing the Esc key soon after the computer is starting up).

(For me the BIOS file was called sp90164.exe)Įxtract the BIOS binary file which sudo apt-get install -y which mkdir cd 7z e sudo mkdir -p ls /boot/efi/EFI/HP/BIOS/New | wc sudo cp *.bin ls /boot/efi/EFI/HP/BIOS/New | wc the BIOS Than what is already installed on the computer. Check that the latest available BIOS version is newer.As operating system version select Window 10 (64-bit).In the web form copy and paste the previously detected HP serial number (XXXXXXXXXX) and search for it.dev/sda1 1,9G 23M 1,9G 2% the HP serial number sudo cat this example the HP serial number was replaced by XXXXXXXXXX)ĭetect the current BIOS version and date sudo cat /sys/class/dmi/id/bios_version df -h /boot/efi/įilesystem Size Used Avail Use% Mounted on To be able to store the BIOS binary file. UEFI is that there is enough disk space free under /boot/efi lsb_release -dĭescription: Ubuntu computers nowadays use UEFI if then echo UEFI is active fi This was done on an Ubuntu 18.10 computer. Method Detect information about your computer Maybe this method might work for other HP computer models too? Hardware: HP EliteDesk 800 G2 TWR (L1G77AV).Operating system: Ubuntu (installed in UEFI mode).I guess this method is not supported by HP, so I add this warning: a BIOS upgrade, if failed, can break your computer! Requirements This method worked fine on an HP EliteDesk 800 G2 TWR when I tested.
