July 7, 20179 yr Had hoped to make more progress than this before asking for help, but here I am. Attempting to install on an Asus STRIX z270h, have used 2 usb drives, each of which has a serial number (one Verbatim Executive metal 16gb, one Sandisk Relay 4gb). Both formatted to FAT32, renamed UNRAID, makeboot run successfully as admin on win10 machine multiple times, plugged into motherboard ports as opposed to front case ports. USB set to 1st boot device, even completely disconnected SATA windows drive. Nothing I have done results in booting to the usb drive. Also tried on an old Gateway laptop, didn't see the usb drive either. Has to be something simple, but I am out of ideas. Where do I start?
July 7, 20179 yr Community Expert Are you trying to boot in legacy mode or uefi? 6.3.5 only supports legacy, 6.4rc supports both.
July 7, 20179 yr 7 hours ago, btrcp2000 said: USB set to 1st boot device, This is ambiguous, as most BIOS's have USB Removable as an option in the boot order, but the flash drive is actually listed as a hard drive. If this is the case, hard drive should be the first (and only) option in your boot order, and under BBS Priorities you set the flash drive to be the first (and only) option (ideally, the non-UEFI version that's listed of the flash drive)
July 7, 20179 yr Author Thank you both. Great to know there is a reachable support community. Been about 8 years since I last homebuilt, but now I know what UEFI is. Fumbled my way through the Bios settings, and apparently up and running, just downloaded the trial key. Now it wants an "array". What's that?..... (j/k) Interestingly, it still doesn't like one of my flash drives, which is the same one I put in the old laptop that shouldn't have had UEFI issues. Grabbed another cheapo off the shelf that worked fine.
