AB350M PRO 4 - no disks while ultra fast boot

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi, i have problem. If i turn on "Ultra Fast Boot" option on my AB350M Pro 4, the disks are not detected. When I turn on my PC, the blue screen pops up saying that needed device isn't plugged and screen is freezed so i cant access UEFI by pressing F2.
Furthermore, when i have CSM turned off my disks aren't detected in BIOS but the system boots normally.
(Sry for my English)
How can I make ultra fast boot option working? SSD is of course on GPT filesystem and windows is installed in UEFI mode.

	Problem SOLVED. The EFI system partition was somehow installed on my 2nd non-system disk - HDD. After creating EFI system partition on my SSD and using bcdboot, setting the "SSD" EFI system partition to 1st boot option, deleting the HDD EFI system partition ultra fast boot option worked.
