2019-12-30 03:43:47 Alex Tu description There's a well know issue that BIOS raid is not be natively recognized by Ubuntu. So, we used to change it AHCI mode in BIOS setting before installation. But, if you have a windows machine which already created raid by BIOS, then only change it to AHCI mode in BIOS setting might not solve your problem. Because of BIOS wrote some header on your disk during creating raid. So, the storage is actually be treated as a disk which not existed partition table. There're 2 workarounds can be done to fix it. - re-create partition table on target disk. - destroy raid by BIOS setting. I create this ticket is to find some better solution guild people do that to improve user experience. There's a well know issue that BIOS raid is not be natively recognized by Ubuntu.
