After flashing the BIOS on my DZ77BH-55K my USB flash drive containing VMware ESXi does not automatically boot anylonger. I have verified that USB boot and USB boot first is checked in the BIOS. I have tried setting the device as the first device to boot in the boot order. I can boot without issue if I use the F10 to boot the device manually on boot, so I know the USB device is bootable and working.
Anyone else with this same issue?
I understand that after you updated to BIOS version 0085 you are not able to boot automatically from your flash drive.
In regards to your report, we don't have any other reports like yours, try creating another USB device bootable to check if it will boot directly from it.
