While I haven't used Veracrypt, Windows Bitlocker should also work. It can be setup to ask for a password on boot. Also, Linux can read and write using either dislocker or the newest cryptsetup, which I have not tested yet. I am using dislocker successfully to read and write to a bitlocker NTFS partition.
