Increase Size of Recovery Partition

The procedure below assumes a standard Windows 10 | 11 installation where the Recovery Partition immediately follows the Windows OS partition

1. Run Command Prompt as administrator

2. Check the Recovery partition is enabled

reagentc /info

If the Recovery partition is enabled disable it

reagentc /disable

3. Shrink the Windows OS partition by 250MB so as to increase the Recovery partition by the same amount

diskpart
list disk
sel disk [OS disk index]
list part
sel part [OS partition]
shrink desired=250 minimum=250
sel part [Recovery partition]
delete partition override

4. Create a new Recovery Partition.

Depending on whether the partition style is GPT or MBR they have different commands. In the results of “list disk” command if there’s an asterisk * in the OS disk row it’s GPT otherwise it’s MBR

GPT

create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
gpt attributes =0x8000000000000001

MBR

create partition primary id=27
format quick fs=ntfs label= “Windows RE tools”

5. List partitions to check increased Recovery Partition size and Exit Diskpart

list part
exit

6. Enable WinRE and check its correctly enabled

reagent /enable
reagent /info
