Windows 10: Need some help creating a new EFI Systeam Partition

Current OS: Windows 10
Currently my windows has a 100 MB efi system partition, however, I would like to create a bigger one instead (550 MB) so that when I install Archlinux as a dual boot, I could utilize systemd-boot as a simple way of booting both operating systems. However, because doing it this way, a minimum size of 550 MB is recommended for the EFI system partition because arch's linux kernel as well as initrd will be put onto the partition as well.

so far i have created a new efi system partition of 550 mb by using diskpart in windows, and it's properly formated as fat32, however while browsing the web for the next step, i came across two methods found in another thread.
Moving / recreating EFI partition - Page 2 - Windows 10 Forums

in which one guy said to use bcdboot X:\windows /s S:
(where X is the volume letter where window OS resides, and S: is where the newly created efi system partition just created)

whereas, another person said to use xcopy to copy the stuff from the old efi system partition to the newly created efi system partition

do they both work? which would you guys recommend? and furthermore, say i've properly managed to create this new efi system partition and delete the old one, is there even any way to reclaim that 100 MB that was used for the old efi system partition?

or should i use easyuefi? it seems to have the ability to move efi system partition, but without knowing whether it works or not and how reliable it is, i'm afraid to use it.

here is a picture showing window's Disk Management:




80.00 GB is what i allocated for archlinux
the 550 MB EFI system partition is the newly created
100 MB is the old EFI system partition
C: 151.75 GB is where my windows OS resides

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..

Blank EFI Partition

I have an ASUS R558UR.

I had windows 10 installed on my laptop and I decided to again have a clean install of windows 10. I booted from USB and cleaned windows partition i.e. C drive and also cleaned EFI partition. I reformatted Drive and it had also created EFI partition of 100
MB. I installed windows on laptop and setted that up. After installing windows my laptop it started taking a long time to boot about 90 seconds but earlier it took only 7-10 seconds. After analysing everything I found that my EFI partition is blank.

Please suggest me how to write back EFI partition so as to reduce boot times.

Thanks in Advace.

 

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that
