I bought a second hand Dell Wyse 5070 to install HAOS on.
I noticed the 5070 has an embedded installed Windows 10 Enterprice version on a onboard 32Gb storage.
I have ordered a M2 sata flash drive to install Home Assistant on it.
Currently the unit boots directly to Windows 10.
I connected a usb stick into one of the usb ports that contains a bootable Ubuntu image To follow the method 1 Generic HAOS installation. I have switched off Secure boot and UEFI enabled in the bios.
Startiing the 5070 with the usb stick connected and pressing F2 to go into the bios I tried to change the boot sequence to usb however this option is not shown. Also pressing F12 does not give the usb boot option.
How can I get HAOS installed and how to bypass Windows booting up?
Would like to totally erase the embedded Windows but not sure this is feasible or even necessary when having the M2 flash ssd drive installed.
USB boot might be disabled in the BIOS. Try go and set it to factory default and reboot then again with the USB key installed. Also in the BIOS you will have the Data Wipe option - that will allow you to nuke the Windows installation and will prevent issues once you have to install the bootloader, so I’d do that by default.
Do I need to do a BIOS factory reset first and see after reboot the usb stick is detected? If not detected, do a Data Wipe?
By doing the Data Wipe option in the BIOS will this erase the Windows 10 completely? When running Windows I see it is installed on drive C with 32Gb storage and also see a drive Z used by Dell. I guess both will be erased by the Data Wipe.
Can the 32Gb storage be used later on or is it completely invisible then?
The data-wipe is unrelated to the USB key troubleshooting - it’s just a handy way of getting rid of Windows - unless you want to retain it.
Do the BIOS factory reset and then see if you can enable boot from USB.
