Question

is it possbile to make a hard disk img and have write protection but it resets to default on each boot/restart ? example: i install windows 95,drivers and a game and have a checkpoint. i make changes to the system or install something and on each boot/reset it revers to the checkpoint. i tried with "Note: You can write-protect a disk image by putting a leading colon (:) before the image file name in the default setting." but running windows gives errors at boot.

Have you checked that no similar question(s) exist?

I think you don't want write-protection (not least because Windows wants to write to the HDD), but you want all changes to be discarded at the end of the session (like RAMdisk).

It seems that mounting a host folder as HDD in guest OS lacks the capability to actually commit-to-disk the writes, so that missing feature may help for your case? (e.g. if somebody plans to implement the missing feature they should make it optional)

A differencing VHD image may meet your requirements. I don't use it so I can't give you practical advises, but anyway u can try.
