Running Qubes from external usb ssd

Is it possible to install qubes on hdd partition (all data be encrypted), but boot it only if a special usb drive is inserted? And still be able to use sys-usb? And remaining space on hdd be used for windows 10?

Yes, this is possible. See here:

Verified boot on Qubes -- a lofty dream?

Purism are developing Pureboot, complete secured boot process, for their devices. I am not sure how well it works with Qubes OS, but I also hope to use it some day. There is a discussion on their forums about it, but it did not progress very far yet. Upd: Here, they say it works fine already: Librem V4, Qubes, Heads and Librem Key - Librem Key - Purism community. Upd2: Discussion of the Purism company was shifted to a separate topic: Discussion on Purism.
