  1. Restoring efi SYSTEM partition


    Currently if I restore only one partition at a time with Acronis the efi SYSTEM partition is missing some data, side note restoring whole drive works however.But my question is:If I used bcdedit /export c:\bcd.bak first and latter on a blank formatted 260MB formatted fat32 partition did the following:bcdboot C:\windows /s G: /f UEFI // where G is the assigned drive letter for the efi partitionThen after that step run bcdedit /import c:\bcd.bakDoes that actually restore that partition to the correct STATE? Meaning any information that was there prior is now back.Or would it still be missin

  2. Restoring efi (SYSTEM) partition

    Currently if I restore only one partition at a time with Acronis the efi (SYSTEM) partition is missing some data, side note restoring whole drive works however.

    But my question is:

    If I used bcdedit /export c:\bcd.bak first and latter on a blank formatted 260MB formatted fat32 partition did the following:

    bcdboot C:\windows /s G: /f UEFI // where G is the assigned drive letter for the efi partition

    Then after that step run bcdedit /import c:\bcd.bak

    Does that actually restore that partition to the correct STATE? Meaning any information that was there prior is now back.

    Or would it still be missing some critical data that was there before?

    I have a support ticket at Acronis on this.

  3. Restoring efi (SYSTEM) partition

    No, the bcdedit /export C:\bcd.bak is done before any restore is attempted, maybe a month ago.

    Then with the blank formatted efi partition, during a restore I run

    bcdboot C:\Windows /s G: /f UEFI /// this restores the boot no problem

    bcdedit /import C:\bcd.bak //// this restores original bcd.

    All of this works. My concern is it enough to have the efi partition also recognize the Windows recovery partition? And anything else it is suppose to do?

    Or is there another command to run.

    Restoring efi SYSTEM partition

    Move EFI partition

    its to enable win 10 to update to its anniversary edition.. it cant do this due to lack of C drive space i have had a quick try with the trial version of easus.. it didnt seem to be able to do what i want..

    i am assuming i cant just delete the efi partition but maybe i could.. as yet i havnt even figured out how to get into the bios of the thing.. maybe that should be my next step.. *Smile Restoring efi SYSTEM partition :)

    diskpart could probably do it but figuring out how (it aint that user friendly) might be difficult without step by step instructions..
