Have an old BIostar A770E3. Which plays the role of server. Were formerly in the BIOS had CMOS Setup Utility, and today took out the ssd it came at Ubuntu 18.04, put back the CMOS Setup Utility -- 2011 or 2012 as there was instead some long time the default junk in the Bios Setup Utiliy 2006, which does not allow even to boot from SSD and whichever boot mode (ahci/ide/raid/ide->ahci and all the rest) I didn't choose -- always throws on Bio Flasher Utility.
What could be the problem? In what direction to look? Where to dig?
