    Migrating Win7 HomePrem 64bit from a BIOS to an UEFI PC ?


    Peace!

    Just bought me a Win7 Home Premium to replace my trusted (hmm!) old Windows 2000 Prof.

    My current ironware is an Intel Core Duo E6300 (1.86GHz) w 2GB DDR2 from spring 2007.
    I'm planning to upgrade my workstation to at least 4GB RAM letting me comfortably run Virtualbox, Sandboxie and maybe also a compressible RAM disk.

    Now with Intel Sandy Bridge LGA1155 motherboards coming out in January and Asus, Gigabyte et al probably skipping legacy BIOS for UEFI I was thinking if you forumistas recommend me postponing installing Win7/64bit until I've received my fortcoming LGA1155 board. Or does anyone know if it's possible to perform a migration from a BIOS PC to an UEFI based one by, for example, using Win7's own image backup and then creating a System Repair disc then to be used for the UEFI migration reinstall?

    I can't seem to find any answers to such a kind of hardware migration...

    Bump!

    Is there still no one who has migrated their Windows 7 (Home Premium 64-bit in my case) from a legacy BIOS PC to an UEFI mobo w/o having to reinstall ?!?

    (I'm eagerly awaiting for my Asrock H67M-ITX to be released here and will be plugging an i5-2500K into the mobo.

    And after that first migration - if possible of course - there waits another one a few weeks later: from my old Samsung 160GB T166 hard drive to an OCZ Vertex 3 SSD!)

    While most people would recommend doing a clean installation of Win7 with new hardware, it's not absolutely required.

    I've swapped the OS disk from an X58 (BIOS) machine to a P67 (uEFI) one. There appeared to be no difference from swapping bewteen two BIOS equipped systems. I'm not aware of any differences, as long as the boot disk uses an MBR (rather than GPT).

    So - if I get this right - you have an UEFI capable BIOS in your new (Asus?) P67 motherboard but have chosen to run the P67 in legacy BIOS/MBR mode in order to avoid a reinstall of your Windows 7/64bit for UEFI/GPT mode. Is this correct?
    (See for example Installing Windows 7 x64 in UEFI mode? - [H]ard|Forum)

    But maybe one could do a dummy install of Win7 in UEFI mode on an empty hard drive (or empty SSD) and thereafter restore an OS image copy of the "old" Win7/64bit (legacy BIOS mode) to the new GPT OS partition and finally execute a Win7 DVD boot repair (http://pcsupport.about.com/od/toolso...tup-repair.htm) ?! Worth investigating ...


    PS!
    If there's any understimulated Windows 7 MVPs out there please feel free to crash this thread!

    Legacy BIOS mode? What's that?

    The boot drive was configured with an MBR. A uEFI is supposed to permit a GPT drive to be used as a boot drive under Win7, but it doesn't require GPT.

    Perhaps I'm displaying my own ignorance, but you seem to have an exaggerated idea about the significance of uEFI.

    As the Z68 chipset boards is not coming before middle of May I haven't a PC to try this
    Change the booting style of Windows Vista or 7 x86_64 versions from BIOS-MBR mode to UEFI-GPT mode without formatting or reinstalling - InsanelyMac Forum
    on. But hopefully it will work out as written in that forum post.

    That is if you want to change the partition style.

    If you are planning to keep mbr style - should be fine to restore an image.
