Hi I have a imac 2017 with a pcie ssd 256Gb installed and a 1Tb hdd

This seems to be a non-standard disk configuration. Was the original Apple SSD (normally 120Gb) replaced?

I was wondering wether its possible to do a bootcamp with w10 on the pcie ssd?

If your Mac is supposed to have a Fusion drive, Bootcamp Assistant will use the 'slower' drive to install Windows.

using hdd for storage

You have two different issues to address....

• Check if your model is listed in https://eshop.macsales.com/Service/Knowledgebase/Article/12/776/Aura-Pro-X2-SSDs-Boot-Camp-Compatibility and if it has the X2.
• You need to have a Fusion drive since you have two physical disks, and BC Assistant will not support installing Windows in a split Fusion configuration.

Are you planning to use a HDD or an SSD? BC Assistant can run into issues if it is an SSD. Samsung EVOs are problematic when installing Windows on such a configuration.
