Windows 10: How to extend EFI Partition from 100MB to 1GB

I have a 100MB EFI Partition on my laptop with Windows originaly, I want to dual boot a linux os as I need it for work, however, It come up with EFI Partition not enough. I prepared 900MB unassigned free space and want to merge with the original 100MB to from a 1GB EFI Partition by using the Windows partition tool.When I tried to extend the EFI partition, it do not work, there is not an option of extendHow to extend EFI Partition? I do not tried to use diskpart command before because I am worry that I will distroy the system

Expanding EFI partition and moving MSR partition.

I would like to install Mac Os on this device. However I am limited by the size of the EFI partition. Mac Os requires at least 200mb. I have only 100mb. So I resized the Windows partition to leave 100mb unallocated. However I can't extend the EFI partition
because there is a MSR partition in the way. https://puu.sh/rFbsz/e52c847706.png

I know both the EFI and MSR partition and very much required partitions for proper functioning and it is better to not mess with it. But I have to get the EFI to 200mb. So how to move the MSR partition. I am pretty familiar with DISKPART or other GUI based
partition managers.

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..

Efi partition between two partitions

Hi,

I have an asus tuf fx55dt laptop with a 256gb ssd that has windows installed on it and a 1 tb hard drive as well.

I am going to list the series of events that took place :

1) I installed ubuntu by creating a 300gb partition on my hdd.

2) ubuntu was not booting up without my charger connected so i decided to remove it.

3)ubuntu was installed in a 292gb parttion and a 500 mb efi partiton was also made on my hdd.

4) i deleted the ubuntu partition and an unallocated space of 292gb was made.

Then i tried to extend my 640gb partition in order to have my full hdd space back. But my 640gb partition did not extend to take up the 292gb unallocated space because the 500 mb efi partition is in between the two major partitions. Also my 640 gb partition
turned into a simple volume from a primary one.

So now i have a c drive(ssd) with my windows installed and having a seperate efi partition of its own and a d drive(hdd) that has no os on it but has a 500 mb efi partition in between my major partitions.

Also i think my booting still takes place through the d drive efi partiton becuase whenever i boot into my pc first grub shows up followed by the windows bootloader.

I need to get my hdd space back. Please help.
