What's the minimum reserved space

[Josh65-2201]

I'm trying to make a 15GB boot file area on my storage drive that's 2TB. When entering 2032 GB in reserved space it says it's invalid it also does it with 2020GB

Most 2TB drives are less than 2000GiB in size
Note that manufacturers use '1TB' = 1,000,000,000,000 bytes
whereas 1TiB = 1024 x 1024 x 1024 x 1024 = 1 099 511 627 776 bytes

Just try a smaller size for the reserved space and see what you end up with.

It doesn't seem to be a conversion issue since I can put in 1500GB and it preservers it at that, same with any other accepted value.

Edit: Never mind i was not reading maximum windows stated. I instead used ventoy reported max size of the drive.
