Failed to craete EFI Boot variable entry: Invalid argument

Hi,

trying to install VE 8.0 on a QNAP TS-251+ : 2 x 4 TB disks ZFS Raid-1 via USB stick UEFI boot

At the end on installing the boot loader it errors out with:

Failed to craete EFI Boot variable entry: Invalid argument
bootloader setup errors:
unable to init ESP and install proxmox-boot loader on /dev/sda2

Thanks

Seems an issue with the BIOS, QNAP tags TS-251+ as legacy and not UEFI, although the BIOS show UEFI-Boot.

Based on testing, ZFS-RAID-1 on root also supports on legacy boot the boot loader on both devices? Though its only available with UEFI?

Thanks

Same Problem with TS-251+

Have you found a way to solve the problem?

Played around with the BIOS settings and at the end it installed fine.

 

[Chrischi]

Could you tell me your BIOS settings and also which version of BIOS you are using?

at the end it was with high probability to boot from the Proxmox USB stick not in UEFI mode (Boot option #3)
