    EFI System Partition Curiousity


    I'm preparing to upgrade a laptop from HDD to SSD. It had a second Recovery Partition in the beginning of the disk, which we know can be deleted from v2004 on.
    Because I plan to transfer everything by Disk Image restore I thought I would clean up the disk beforehand and delete the extra Recovery Partition. While I was at it I figured I could also move everything remaining to the left to use up the unallocated space, so I did the job using MiniTool Partition Wizard 9.1 on CD.

    Deleting the partition was normal, but when I went to move the EFI System Partition I saw that the size - instead of being the 100MB shown in Disk Management - was showing up as 234MB in PW before doing anything. Moving the slider to the left just made it bigger, of course.
    Since this was odd, and in the end not really an important or useful task, I aborted and left it as is- just deleted the extra Recovery Partition. It will all be moot when I switch out the HDD.

    But now I am curious: why would Partition Wizard be showing this 100MB partition as 234MB?
    Any ideas?

    The disk before doing anything:

    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 EFI System Partition Curiousity :)

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

    EFI System Partition

    So, an EFI system partition is perfectly normal on a Windows 10 disk (I assumed you've done an internet search and discovered that this partition is for booting your system).

    Are you trying to backup the contents of this partition?.... if so, what software are you using?
