Not enough storage for imaging?

Not enough storage for imaging?

USB Boot media...

When I try to create an image it shows not enought storage on the repository....

Real free space on server is 236GB, If I uncheck WINRETOOLS & DELLSUPPORT partitions it works (I assume beacuse total image is around 2GB smaller)

but ┬┐It calculates the needs based on total size or used size? Because client system to image is only used around 80GB of 235GB total size
