    Win 8.1 installation disc for UEFI

    I am going to build an 8.1 UEFI desktop with an EFI partition. Can I do this with any Win 8.1 installation disc? Do you need a special version of 8.1 to create a UEFI computer?

    No you don't - any will work. You will need the correct version (x64 unless you have a reason not to). You'll need your key as well of course.

    Btw, only 64 versions support UEFI and SecureBoot. Make sure to buy a x64 version of either 'Windows 8.1 Single Language" or "Windows 8.1 Pro" edition.

    Why would anyone buy single language? Up till now 32 bit windows has not been able to boot under efi.

    Vista x64 and 7 x64 support it.

    Efi has a lot of limitations and annoyances, but that isn't one of them. It is a windows limitation.

    Hi there

    UEFI is fine -- it's usually Protected / secure boot that cause all the hassles and people often think UEFI means secure boot -- IT DOESN'T.

    Protected boot is some HORRIBLE system kludged up by Ms (who else could devise such a stupid system) that locks the Windows install keys in the BIOS. It also disables booting any "Non registered" OS. So the first thing is to DISABLE this and if your computer allows it enable LEGACY boot in the BIOS.

    Now you can boot UEFI or Non UEFI systems at will. There's nothing wrong with UEFI -- by having a GPT disk you are freed from the stupid restriction of a maximum of 4 primary partitions on your HDD -- with large HDD's (4TB one's are increasingly common) you might want a more flexible partitioning arrangement which UEFI does.

    If you are creating Portable systems then its best to go for a NON UEFI version -but remember if you use Virtual machines you can actually create a UEFI virtual machine even if its running on a non UEFI computer.
