A while back I posted a tutorial on installing Windows from inside Linux.
Mind you, the versions have changed since, so it will be wise to get the new version instead of the now outdated one. I’ll be doing a video on that too.
Per your C and D drives, your Zorin installation can normally see them in your File Manager, under the “Other Locations”. Naturally, they’re not named C and D, so you’ll have to open them to see which folders you’ll need. In the Windows installation one, your required folders are under Users (and your login username).
In order to utilize those folders under the VM, you will need to add them as shared - or simply connect them only to the VM as devices, provided the device you connect does not have Zorin installed (even in another partition).
You are very welcome @AT100,
There is an easy method to do this. Boot normally into your Zorin and start Disks (or Gnome Disks - as they are the same app). Then select your big drive and follow the steps of the images below.
First, make a folder you want the drive to mount on:
Then, go to Disks and follow the images below (select your big drive and then the bar as shown on the image):
Important: Replace the “your_username” in the picture above with your actual username folder, found in the /home directory - otherwise it will not automatically mount.
After that, your D drive should mount automatically on the designated folder after every reboot. To mount it during your current session, look at the first picture attached and click the “Play” button that will exist left of the gear icon I highlighted. If it’s already mounted, there will be a “Stop” (square) button. Hit it and then the button will turn into a Play one (Triangle). Hit it so that it mounts on the new location.
