    BIOS MB & UEFI MB Installation


    I have an SSD System Drive which contains Win 7 64bit Professional OS and all of my Programs, which was built on a GB BIOS MB, so has MBR Boot Sector.
    I wish to transfer this SSD, complete as is, to a new GB MB which has UEFI Boot Sector and then install Chipset Drivers.
    a) Is this idea sound.
    b) Are there any associated issues doing it this way.
    c) Recommended Best Procedures, if my idea is wrong.

    Experts advice please.

    You can use the SSD as is, you don't have to use the UEFI "GPT" drive format.

    However, is the Win 7 64 bit Professional you have an "OEM" version or a full license version? If its an OEM version legally it is only licensed for the original PC (motherboard) it was installed on. Its iffy on whether Microsoft will activate an OEM on a different system. If its a full version there shouldn't be any problem activating it on the new motherboard.

    Thank you for this info.

    Which is more beneficial to me:
    a) As you have quoted: SSD as is as BIOS MBR Drive.
    or
    b) Format SSD as GPT and install W7 as UEFI on GPT.
    c) What are the pitfalls of (b), if any.

    Once you`re in windows you won`t see any difference.

    I always use Legacy Bios and MBR, never have any issues :)

    If you have less than a perfect Clean Reinstall Windows 7 as compiled in the blue link, then I'd consider reinstalling and use UEFI so you can try the extra features of a UEFI BIOS. My impression is they may be a bit more stable after using one for several years now on my laptop. But of course the SSD will cover the faster boot.

    If you want to transfer your present install it may require Adjust Win7 to boot on new hardware with Paragon Adaptive Restore CD which makes this so easy we have preserved it for others' from the earliest days of these forums.
