Cannot boot unRAID - Dell Precision 5520 (Laptop)

[flashcat666]

Hi everyone,

 

Before I move into the wonderful world that unRAID seems to be, I wanted to use my laptop to at least run unRAID and see how it looks, play a bit with the settings, etc., before I go and spend some money on actual dedicated hardware.

 

I have a Dell Precision 5520 (mobile workstation), nothing too fancy. I've followed all the instructions (moved from RAID to AHCI in the UEFI, disabled Fastboot, etc.). I can't disable USB3 or even 2, as that's not a possible option, and some setting seems to force me to use UEFI boot, as the Legacy Boot option is greyed out.

 

I downloaded the unRAID USB tool and installed on it (with the UEFI customization) on an 8GB USB 3.0 drive that I know is working. Booted the system: It hangs for 2-3 seconds after selecting the USB key and then goes straight to Dell's SupportAssist window that does a system scan (RAM, disk, etc.) as if there was a problem.

 

I tried a few times to make sure, same thing.

Grabbed a known working 2GB USB 2.0 drive, did the same install using the USB tool: Same exact behaviour.

 

I tried just downloading the package and manually running the batch file: Same behaviour on the two keys.

Tried it again but this time running `syslinux.exe -ma F:` to see if it did a difference: Nope.

 

Do I just happen to have an incompatible type of system/UEFI and it simply won't work, or I'm doing something wrong ?

 

Thanks in advance for the help!

Are you booting in legacy or UEFI mode?   If UEFI mode have you made sure that the EFI folder on the flash does not have a trailing ~ character (if so this needs removing to enable UEFI boot).
