Errors when install Ubuntu on Gigabyte MB

[BennyBeat]

tried to Create a Dual Boot computer with Win10 + Ubuntu 20.04.2. Win10 install with no troubles. Ubuntu installed in EFI/Legacy Mode, Native IDE/AHCI/RAID Mode using several methods (USB with Yumi, Rufus and Ventoy; also burning a DVD) on SSD Crucial but problem persist. Same using other Debian x64 based distros, such as Xubuntu, Linux Minut, Elementary and ZorinOS...
