The recovery image, winre.wim, is typically between 250-300MB, depending on what drivers, languages, and customizations you add.

A minimum of 52 MB is required but 250 MB is recommended, to accomodate future updates, especially with custom partition layouts.

The Windows Recovery Environment (Windows RE) tools require additional free space:

The Windows partition must have 16 GB of free space after the user has completed the Out Of Box Experience (OOBE) and Automatic Maintenance has completed.The Windows partition must be formatted using the NTFS file format.The partition must have at least 20 gigabytes (GB) of drive space for 64-bit versions, or 16 GB for 32-bit versions.In the list of drives and partitions, confirm that the system and utility partitions are present and are not assigned a drive letter.The list of available drives and partitions appears. Click Start, right-click This PC, and then click Manage.

To verify that system and utility partitions exist For more information, see the MSDN topic: PARTITION_INFORMATION_GPT structure.

When you're deploying Windows by using DiskPart, use the attributes volume set GPT_ATTRIBUTE_PLATFORM_REQUIRED command after you create the partition to identify the partition as a utility partition.

This prevents these partitions from appearing in File Explorer. Protect end users from accidentally modifying utility partitions by identifying them using a GPT attribute. This allows end users to perform actions such as resizing the Windows partition without affecting system utilities. Other utility partitionsР”Р„ny other utility partitions not managed by Windows must be located before the Windows, data, and recovery image partitions. The MSR is a reserved partition that does not receive a partition ID. In WindowsР’В 10, the size of the MSR is 16 MB.Р”Р„dd an MSR to each GPT drive to help with partition management. 512 bytes x 65527 = 32 MB, which is less than the 100 MB minimum size for this partition. The minimum partition size of FAT32 drives is calculated as sector size (4KB) x 65527 = 256 MB.Р”Р„dvanced Format 512e drives are not affected by this limitation, because their emulated sector size is 512 bytes. This partition is managed by the operating system, and should not contain any other files, including Windows RE tools.Р”Р‡or Advanced Format 4K Native drives (4-KB-per-sector) drives, the minimum size is 260 MB, due to a limitation of the FAT32 file format. The minimum size of this partition is 100 MB, and must be formatted using the FAT32 file format. This partition is usually stored on the primary hard drive. On GPT drives, this is known as the EFI System Partition, or the ESP. The device must contain a system partition. Additional drives may use either the GPT or the master boot record (MBR) file format.Р”Р„ GPT drive may have up to 128 partitions.Р”В®ach partition can have a maximum of 18 exabytes (~18.8 million terabytes) of space. When you deploy Windows to a UEFI-based device, you must format the hard drive that includes the Windows partition by using a GUID partition table (GPT) file system.

If you use a custom partition layout on WindowsР’В 10 or Windows 11 for desktop editions (Home, Pro, Enterprise, and Education), update the push-button recovery script so the recovery tools can recreate the custom partition layout when needed.
