Windows 10: I am stuck in EFI System Partition at 266MB. I have 57GB and have only used 13GB. Windows 11.

I am stuck in EFI partition at 266MB. I have 57GB and have only used 13GB. Windows 11.I've tried a few 3rd party disk management programs with no luck. unable to use the 57GB partition.

:)

 

My EFI System and Recovery Partitions are on the wrong disk (Windows 10)

Please boot into WinRE and do the following:

1. Delete the EFI partition on disk 0
   
2. Re-run the bcdboot command suggested earlier. Be sure to use the correct drive letter. You can determine the OS partition's drive-letter by running diskpart & list volume commands.
   

Edit:

"Volume Z" gave you two more options. If you don't mind having the EFI on disk 0, then all you need to do is delete the unwanted boot entries using msconfig.

OTOH, if you want to have the EFI partition on Disk 2, then delete the EFI partition on Disk 0 and run the bcdboot command.

I wish I could handle your problem, however, analyzing issues related to MBR2GPT requires deeper knowledge of the underlying workings of the MBR2GPT tool, which is beyond our technical reserves.

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..
