received HP-T730 today and having some issues installing Ubuntu and Proxmox on the m.2 SSD drive. When installing Ubuntu, I was only able to use it after the first reboot. If I shutdown and restart T730, I got No boot disk error. Then I tried to install Proxmox, at the end I got the error 'Unable to install the EFI boot loader on '/dev/sda'.
Was it a bad drive, or is some BIOS settings needed to install Ubuntu/Proxmox properly? I am on BIOS version 1.15
Update: In BIOS, the SSD drive is listed under 'Legacy Boot Order'. Is it possible to make it appear under 'UEFI Boot Order'?
Update 2: Defaulted the BIOS settings and the SSD drive now appears under UEFI, and proxmox installation was now working.
Update 3: Argh! After power off and on T730, I now get 'Boot Device Not Found' error. Press 'F9' to choose boot device and the SSD was not listed in the UEFI boot source. Press 'F10' into BIOS setup and the SSD is listed there. Did a disk diagnostic check and it passed 100%. BIOS Secure boot is turned off, Legacy Boot Source is turned off. Anyone encountered this issue?
