    Hello,
    My Bios v.217 hast lost CSM/Legacy Options and SecureBoot.
    Current situation: UEFI boot only, secureboot enabled, win10 installed on gpt disk.
    Win10 works normally, but impossible to boot a MBR usbstick, and for personal reason I want to go back to Win7 with MBR scheme. I tried to flash older bios without succes (forbidden by FastFlash). I also disassembled to remove CMOS battery (5 minutes, not enough maybe), no progress.
    May be I should remove the CMOS battery for 2,3 or 4 days to reset the bios completely??
    Is there any solution to recover those options (CMS, secureboot) ?
    Any help would be greatly appreciated
