Allow UEFI Boot

Yesterday i started with Unraid, bought the pro license, dont need it, but just to support the unraid team! read a lot in this subreddit, and watching youtube video for hours...spaceinvader one!

I build my new server pc, inserted usb stick, created with the unraid usb flash creator. But my server wont boot to unraid. I switched a lot of BIOS settings, but nothing helped.

Then i formatted my usb flash drive, but now marked "Allow UEFI Boot" in the flash creator, booted instantly! Why is this option not switched by default? or i'm i the only guy with this issue?

Most newer motherboards will only support UEFI. If it’s working great carry on

The preferred Unraid boot is using Legacy (non UEFI) boot. This is something you'll have to look for in your BIOS.

Just continue with your UEFI Boot..it's fine...but take note, if you experience VM/passthrough issues....you might want to dig DEEPER into your BIOS and find out if there really is an option you kissed on your motherboard to boot in Legacy (non UEFI) mode.

Hmmm, i'm want to use plex hw transcode (Intel Quicksync). I hope this will not break myy wishes..

I think i found the issue.. from the datasheet of my motherboard " No legacy OS support, no MBR installation (UEFI only due to Intel restrictions) "

Well, there ya go. Generally speaking, you should be fine. I just wanted to mention that it is a possibility. Just follow all the guides out there... especially SpaceInvaderOne YouTube guides

Followed the plex hw decoding tutorial, and it's working! :)
