Hi Guys,
Any update on UEFI boot solution on Dell PowerEdge T420?
I have similar issue. The UEFI boot with Unraid gave me "booting kernel failed: bad file number".
I am actually trying to test Unraid on my old Dell server running EXSi. I was not able to boot up USB Unraid automatically via UEFI mode.
When I set the boot setting into the BIOS Boot (Instead of UEFI mode) and manually select the Unraid USB drive. It boot up nicely.
However when I tried to boot up automatically, the server boot into Hard Drive C (EXSi installation) instead of Unraid USB drive even with higher Drive sequence order. I will double check again if Drive sequence order was set correctly. I was not to sure.
I notice there is option to Disable Hard drive C. I am not sure if this should be disabled. What I want is first boot into USB when fail go to Hard drive C (EXSi).
This way I can switch between Unraid and EXSi as needed without meddling with BIOS setting again. With UEFI mode this is possible.
