Unable to select the boot priority sequence in the ASUS TUF Gaming B550M-E WIFI BIOS
Unable to select the boot priority sequence in the ASUS TUF Gaming B550M-E WIFI BIOS
At the bios I cannot set the boot priority order. Even when I turn on CSM and choose my main drive as first boot, it still starts from the old backup drive that was used before. It always shows the previous PC drive as the Windows installer manager. I cannot adjust this setting.
I need to turn off CSM so the system boots automatically into my main drive. After enabling CSM and switching to view legacy and UEFI drives, only two drives appear in the boot priority list even though all four are detected by the bios. I’m unsure if there’s a solution to fix this. I want to set the boot priority as it happens, because my motherboard sometimes boots into a faulty second drive without a post.

Oh dear, I need to change the format of the entire disk? I've already looked into it. It's a GPT partition. UEFI only works with GPT. That drive is already set to UEFI mode.
