Windows uses its own system (fast Startup) to speed up the boot process.
And fast boot, really doesn't have any function anymore.
A2 would indicate that a SATA device is not found.
For Fast boot, Windows must be installed in UEFI (GPT) Mode, and your graphics card (don't know if you use a graphics card?) Must support GOP, only then Fast boot can work.
But it is not a motherboard issue, but more likey a partitioning issue]]> Thu, 09 Mar 2023 22:43:20 +0000 https://forum.asrock.com/forum_posts.asp?TID=25521&PID=103909&title=ultra-fastboot-does-not-work#103909 https://forum.asrock.com/forum_posts.asp?TID=25521&PID=103621&title=ultra-fastboot-does-not-work#103621 Author: Fernosty

I have the configuration:
Motherboard: Asrock B760M PRO RS/D4
CPU: i5 12400
SSD: M.2 Kingston FURY Renegade Drive [SFR/1000G]
RAM: x2 GEIL 16GB PC4-19200 CL17-17-17-39 (Overclocked to 3200)
OS: Windows 11
Bios mode: UEFI

When I turn on the fast boot function, I have an error code A2, if I turn off this function, the system boots without problems.

I tried to remove RAM overclocking, update the bios to the latest version 2.05, completely reset the bios. Maybe someone has encountered a similar error?]]> Thu, 23 Feb 2023 17:18:14 +0000 https://forum.asrock.com/forum_posts.asp?TID=25521&PID=103621&title=ultra-fastboot-does-not-work#103621
