Re: Unable to boot from internal hard disks on new PC

Hi, just a couple of thoughts from left field.  I've avoided UEFI and Secure Boot and come from another era, but FWIW I'll cherrypick a bit ..

Didn't you say you'd disabled that?  What does 'Custom' come to?

Is that 2 pairs of disks on 2 controllers, or what?

Main thing I've wondered: maybe it's expecting to boot off that, at least preferably?  Have you considered removing it to see if it then sees the SCSI disks?

That seems to only cater for net booting.  How did you get it to boot from the USB installer?

Maybe a slower boot might show more, or for longer, about what it's doing, or trying to do?

What's that about?

Again I wonder what that means, if not disabled?

Good luck, though you shouldn't need luck with that sort of kit ...
