Did that on Friday. I created a single NTFS partition on an MBR mode SSD and installed Windows 11 there. It worked. Apart from some M.2 SSDs that you cannot install Windows in MBR mode, they boot only in UEFI mode, I don't know of any other device that would not work in a legacy installation. Please explain.

    Legacy MBR installation, no TPM, no Secure Boot, no WDDM 2.0 graphics drivers, no SSE4.2, cannot get more unsupported ;) This is only my test laptop. I had installed Windows 11 here before upgrading my main PC. For my main PC I use everyday see my 2nd system specs.
