Remove Windows from Dual Boot Setup?

I ran into an issue on Bazzite that’s temporarily put my Windows-removal plans on hold. Twice now, when trying to log on to USAA on Bazzite in Brave, all I’d get is a popup saying:

We are unable to complete your request.
Our system is currently unavailable.
Please try again later.

It then happens with my other browsers and in a Windows container under WinBoat. If I boot into real windows, I can log in without problem. At that point, when I go back to Bazzite and try it there, it works just fine. So, until I can find a way to clear that problem from within Bazzite, I’ve decided to keep my Windows dual-boot setup.

BUT, I did recover most of my Windows disk space and give it to Bazzite by:

  1. Booting into Windows,
  2. Moving all my Windows special folders from where I put them on the D: drive back to their default position on the C: drive,
  3. Shrinking the C: drive down to a smaller size,
  4. Booting into the Bazzite Live ISO,
  5. Running GParted,
  6. Deleting the old Windows data (D:) drive,
  7. Moving all the remaining partitions to the left and resizing the Bazzite partion to use all the free space.

Everything seems to be working fine.
