Enable Fast Boot, SATA support, Hardware Fast Boot, Launch CSM.
Boot Device Control: UEFI and Legacy.
Boot from any devices: Legacy OPROM first.
SATA configuration: AHCI.
Disable Hot Plug on all ports except those set for eSATA.
Enable Hardware Prefetcher, adjacent cache line prefetch, Dynamic Storage Accelerator
Boot performance mode: Turbo
I also disabled Network Stack because the bios does not have any web interface nor update, which is really outdated.
Apart from the default bios settings which you should keep as they are, make sure you enable iGPU Multi-Monitor, all virtualization features and all bios password.
If still having troubles, reboot more than once into Safe Mode and uninstall any SSD utilities.
