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

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

How to install Win10 when the Recovery & EFI partitions were deleted?

There are a couple of issues with the above sequence. First, @drpeppercan stated that they already deleted the EFI system and recovery partition. So why is there a select part 1 and delete part override in the command sequence? What is being deleted? The Microsoft System Reserved partition? Hopefully there is an MSR partition there because if partition 1 is the Windows OS partition, then you just deleted Windows. And if there is an MSR partition there, why delete it?

Second, without a size specified when creating the EFI System Partition, it is just going to fill all available free space at the beginning of the drive. If there was a recovery partition, EFI System Partition and MSR partition, that free space is likely to be 600 MB is size, so you just created a 600 MB EFI System Partition that only needs to be 100 MB in size.

Without seeing the layout of the disk with: select disk 0, detail disk, list part you can't really suggest an accurate list of commands to rebuild the EFI system partition. It's only guessing.
