B550 Tomahawk lacks RAID configuration options during startup.
B550 Tomahawk lacks RAID configuration options during startup.
During the first Windows setup, BIOS was configured to start from an AMD RAID controller using a pre-set array through just the M.2 port. Everything functioned properly initially. After installing Windows, I needed to set up my three 3x spinning drives in RAID 0 for the installation. Using BIOS settings, I removed the existing array and changed the boot controller selection. Now only the NVMe controller appears for booting, but the Windows installation remains on the AMD RAID setup via M.2. I haven’t saved the array configuration, so I can’t recreate it. The UEFI HDD is now showing instead of the AMD RAID. I’m stuck—can’t select the correct RAID controller for boot. I tried clearing CMOS, but it didn’t reset the settings from the RAID Xpert menu. They still reflect my incorrect configuration. Please help!
