I recently purchased a Lenovo P53 that comes with a factory-installed Windows operating system. However, I prefer to use Linux and do not need Windows. In the future, I may want to give this machine to someone who prefers Windows, so I want to have the option to put Windows back on it.

One option would be to swap the boot drive with an empty one and keep the Windows one, but this would be expensive as the boot disk is a large SSD. Another option is to use an external Windows installation disk, but I am not sure if this is a viable option.

I am also considering saving the current Windows installation, either by saving the partitions or the whole drive. I am wondering if the UEFI boot partition should also be saved, how to properly restore them on a new disk, and if the Windows partition can be shrunk before saving.

I am also wondering if using TRIM commands and compressing the drive will ensure a successful restoration on a different disk in the future. Lastly, I am considering keeping the recovery partition, which is a 1 GB partition labeled “OEM partition” and is about 60% full.

I am wondering if this is a recovery partition, if it can be saved and restored, and if it can be left on the machine to be used by the BIOS in the future.

Is this a recovery partition? Can I save/restore it? Can I just leave it there (1GB isn’t much) and hope that the BIOS can still use it?
