Dual-booting VeraCrypt Windows and Zorin on LUKS

Hi,

I recently migrated (or tried to) from a dual-boot VeraCrypt Windows + LUKS Linux Mint to the equivalent with LUKS Zorin instead, but Windows screen is all scrambled even before I VeraEncrypt the Windows partition.

I followed the same process for Zorin that what worked with Linux Mint:
1. Install Windows as the only OS
2. Shrink the main Windows partition to the desired size (64 GB in my case), using the Windows disk manager. Check that Windows still work properly.
3. Boot with the Linux distro, use the manual partitioning, create an EXT4 /boot partition of 512MB, and use the rest of the disk as a LUKS container.
4. Mount the uncrypted LUKS container as /
5. Complete the installation of the Linux distro.
6. Encrypt the Windows partition with VeraCrypt with the multi-boot option in VeraCrypt
With Linux Mint, these steps created uncrypted boot partitions for both Windows and Linux (as well as unencrypted grub and Windows recovery partitions) but allowed encrypted OS partitions for both Windows and Linux OSes and user documents.

With Zorin, when I tried to boot Windows after step 5, the login screen appeared all scrambled (like a CRT screen with a wrong sync, but with diagonal lines) and remain scrambled after I guessed how to login blindly. This was just after installing Zorin on LUKS, before I was supposed to VeraEncrypt the Windows partition - step 6).

Is there a different process to dual-boot Zorin on LUKS with VeraCrypt Windows that what worked with Mint?

As far as I can remeber, the default for Mint on LUKS did not use LVM. When I installed Zorin, LVM was checked by default so I left it as is. Can it be the source of the problem? (Since my only dual-boot install is on a laptop with a single SSD port, LVM as no real value for me for the dual boot installation).

Alternatively, a solution to authenticate an OEM Windows in a VM would work for me too. The only reason I dual-boot is because the OEM Windows version that came with my laptop will not authenticate in a VirtualBox VM so far (which would be my preferred solution) and I'd rather dual-boot than spend 100$ to save a few seconds when switching between OSes (I definitely need Windows for a couple of work-related software that do not work with Wine).

Thanks in advance,



Vincent

Hi, Sorry been long in replying - not something I personally bother with. Best I could find was this thread?:

(Zorin is based on ubuntu, just themed to look like Windows 7 for migrators for ease of transition)
