It was a bad usb installation from Microsoft. I created my own installation USB drive and it works fine. For some reason the Microsoft drive will work with a pic with windows already on it. But not a fresh install. My issue is fixed]]> Sat, 05 Jan 2019 09:52:45 +0000 https://forum.asrock.com/forum_posts.asp?TID=10583&PID=59675&title=cant-load-win-10-usb#59675 https://forum.asrock.com/forum_posts.asp?TID=10583&PID=59572&title=cant-load-win-10-usb#59572 Author: RLGL

I have updated the bios to 1.80. CSM is enabled and Secure Boot is enabled. SATA Controller is Enabled. SATA Mode Selection is set to AHCI as I only have 1 M.2 drive. I have tried Advanced > USB Configuration > Legacy USB Support Enabled, UEFI Setup Only, and Disabled. I turned it back to legacy enabled.

I am using a USB drive windows 10 pro 32/64 bit bought from Microsoft. I inserted this drive into another PC and it works. I just can get my bios settings right to get this USB to boot. ]]> Wed, 02 Jan 2019 10:45:35 +0000 https://forum.asrock.com/forum_posts.asp?TID=10583&PID=59552&title=cant-load-win-10-usb#59552 https://forum.asrock.com/forum_posts.asp?TID=10583&PID=59546&title=cant-load-win-10-usb#59546 Author: Foesaken

Hi all.

I'm having issues trying to load windows 10 pro 64 bit on my new setup. This is my first time loading windows from a USB and first time trying to load windows onto an m.2 drive. Every time I try to load from usb I get a screen that says:

An operating system wasn't found. Try disconnecting the drives that don't contain an operating system. Press any key to restart.

Here is my setup:
Asrock Taichung ultimate z390
i9 9900k CPU
Evga RTX 2070
Samsung 970 NVMe 2TB
Evga 1000 G3
Corsair 2x 16GB 3200 ddr4 ram

In bios I get code a6 from dr debug and when I try to load from usb I get code a3
