- If you are creating a custom copy of WinRE, you will need the Winre.wim file located in C:\Windows\System32\Recovery.
How to create space for the recovery partition
Many users encounter the message “There is not enough usable space for this operation” when trying to create a new partition. If this happens to you, you need to reduce the volume of an existing partition to free up space:

- Set the appropriate partition type: Depending on your disk type, you need to apply a specific ID or attribute:
- For MBR: use
set id=27from diskpart. - For GPT: applies
set id=de94bba4-06d1-4d40-a16a-bfd50179d6acygpt attributes=0x8000000000000001.
- For MBR: use
- Copy the Winre.wim file to the new partition using the appropriate command:
- For UEFI:
mkdir T:\Recovery\WindowsREyxcopy /h C:\Windows\System32\Recovery\Winre.wim T:\Recovery\WindowsRE(T is the letter of the recovery partition.) - To BIOS: use the letter S or the corresponding one.
- For UEFI:
- Record the recovery image with the command:
reagentc /setreimage /path T:\Recovery\WindowsRE /target C:\Windows(changing T for the created unit). - Activate Windows RE again with
reagentc /enable.

Troubleshooting common problems
During the process, it's common to encounter errors such as "Not enough disk space," problems copying Winre.wim, or problems with administrator permissions. The key is to follow each step carefully, verify that the partition is created correctly, and use the correct commands for each disk type (MBR or GPT).
