HAOS not booting past Slot A

Hi Everyone,

I am trying to install HAOS on my rather old Lenovo Thinkpad T530. I have tried flashing the hard drive directly using balena etcher with HAOS 10.1 but without success. I also tried installing Ubuntu and flashing the hard drive through that but came down to the same results.

Now to the the problem, I am not getting past the boot screen showing “Slot A (OK=0 TRY=0)”. I have disabled secure boot and UEFI Only mode is enabled. I’ve tried almost all settings in BIOS without any success.

I have also tried to flashing older versions of HAOS on my drive, 9.5 and 10.0 with the same results.

Please see this album of images with my BIOS settings and my results in trying to boot. Appreciate all the help i can get.
