BIOS does not recognise my SSD with Operating System in UEFI Mode, only Legacy / CSM

I currently want to upgrade to Windows 11. However, my computer is unable to as I have not got Secure Boot enabled. This is because I cannot boot my PC in UEFI mode, as when in UEFI mode my SSD with Windows on does not appear, i.e. the computer does not recognise my SSD in UEFI boot mode. I have read that this is because Windows was installed in Legacy mode, but Windows was installed on this PC many, many years ago so I don't know. Is there a way to make the bios recognise my SSD in UEFI mode?

    Hello Sam, how are you?

    I understand that you would like to convert your installation from Legacy to UEFI, I suggest you check the thread below, but to be safe, always before taking any action, make a backup of the important files on your computer.

    It is very detailed and will be able to assist you in this process.

    When finished, enable safe boot and switch from Legacy to UEFI, and try updating again please..

    Hi

    The only problem here being is that this PC is very new in all its parts BUT the hard drive that the operating system is on!

    The SSD is perhaps, 9 years old. Everything else is under 2 years old - I have in the last 6 monts just upgraded again the GPU, CPU and Motherboard to good current versions. I also have an even older (maybe 12 year old?) HDD, and a much newer M.2 drive.

    As a result - I won't simply be 'getting a new PC' when this one dies, as the hope is it doesn't :)

    So even if it's painful - I do need to find a way to enable secure boot, whether its reinstalling Windows on my M.2 (ideal!) or otherwise - helpfully, I have nothing on this PC other than Games, so I don't really care if it's entirely wiped.

    If there is a way to enable secure boot / UEFI recognise my SSD or Window Operating System - I'd love to know!

    Yes.It will not be worth the bother to try to make it work though. It would require the hard drive to be formatted as ntfs. It is currently most likely formatted as a fat/32 drive. W10 is just fine on that PC, Just wait till that one dies and go to the W11+ when you get a new pc.
