@petrob Welcome to the Rockstor community.
Well done.
Quite possibly. Take a look at @twermann recent thread/post here here:
where the following may help:
This relates to a Gen10 HP Microserver but may help in your case.
Re:
The current installer will install just fine to a bios boot mode system is that is how the installer was booted. But it will install in UEFI mode if it was booted in that mode. That is my understanding anyway. We use the kiwi-ng system to create our installer.
I’m about to embark on creating a Leap 15.3 profile for our installer so hopefully that will be a more forward looking option. But althought I hope to get this done very soon it’s potentially non trivial with 15.3 only being in beta currently; but I’m hopeful. I’ll report back here once it’s done. Also the Leap 15.1 profile and underlying OS is now deprecated and will be removed shortly as Leap 15.1 is now out of support.
If you could do a legacy boot mode install on another machine, or switch the Gen7 N54L to UEFI, then you can always just move the successfully installed Rockstor 4 USB system disk over to the Gen7 and boot from that. You will end up with the donor install hardware Appliance ID but it’s a start.
Hope that helps.
