Package: os-prober Version: 1.74 Tags: patch Veracrypt system encryption for Windows 7/8/10 on UEFI is working by creating an additional efi program on the EFI partition. If this efi program is added to the GRUB menu, then I can successfully boot my system encrypted Windows system from GRUB.
Since in Debian, GRUB uses os-prober to get the additional menu items to present for additional OSes, adding the attached file to /usr/lib/os-probes/mounted/efi/15veracrypt results in a correctly working Veracrypt GRUB menu item. Tested on Windows 10 Home, have no idea about other editions or versions, but most probably this will work for them. Note, that this is only for UEFI, I have no idea how to add Veracrypt to the GRUB menu on MBR systems. Note, that most of this is a copy-paste and customization of the 20microsoft script.
