Windows 10: How can I safely increase the ESP partition?

The default 100MB ESP partition is not large enough for my needs, what's the safest way to increase the size of the partition while still being able to boot windows without needing a factory resetor other systems with a bootloader installed in the same esp partition

:)

 

Increasing Partition Size

You can't remove unallocated space, because it is, by definition, unallocated. Do what LX07 and Cereberus are suggesting and get the free Minitool. Best Free Partition Manager for Windows | MiniTool Partition Free You will be able to shrink "D" and expand "C" easily and safely. Download and install it, and someone here will walk you thru the few simple steps.

 

Lost EFI/ESP Partition | No Room Preceding OS Part | Options?

• Lost EFI/ESP Partition.
• After deleting MSR, on 17Mb is available (tutorial on woshub to re-add ESP + MSR, then copy *.efi files from %windir%)
• Diskpart shrink QUERYMAX tells me that I have 4gb, but wont let me free up (tried 228 [100efi + 128msr as well trying 116 after finding out win10 msr only 16mb).

1. Can I migrate / defreg files to back of disk, opening up more room b4 os part?
2. what about single partition windows installs, where x looks in windir for boot information? where x is ? EFI? BCD? i'm not sure, i got the impression that if no ESP part, windows looks in the %windir%

thanks =)

 

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
