Hello everyone, I’ve been running Bazzite as my primary OS for about 7 months now and love it. I used to have my primary 2TB SSD running Windows 11, my secondary 2TB SSD running Bazzite (main boot for 7 months) and then I recently bought a 1TB SSD so that I can keep a small Windows install for the few things I need Windows for.

I finally bit the bullet and backed up all my important Windows files and wiped my primary 2TB SSD and installed CachyOS on it, and now I can’t install Windows 11 on my 1TB SSD. Bazzite uses GRUB as the default boot launcher, and I can boot into either Bazzite or CachyOS just fine, but no matter what I do I can’t install Windows onto my new 1TB SSD.

I’ve tried multiple options to wipe the 1TB SSD, including using KDE partition manager to wipe everything off of the 1TB SSD, booting into the Windows live installation off of a USB and using the command prompt (diskpart) to wipe the 1TB SSD and format it into NTFS, and deleting the partitions manually in the Windows 11 installer, but no matter what I do, the Windows 11 installer always pops up at the end with a “failed to install Windows 11”.

I have 3 seperate SSDs, two seperate 2TB SSDs, and a 1TB SSD. My main boot is one of my 2TB SSDs that’s running Bazzite, what used to be my Windows 11 installation has been recently deleted and overwritten with CachyOS, and I’m trying to install Windows 11 onto my 1TB SSD. No matter how I format the 1TB, the Windows 11 install fails when I try to install it onto my 1TB SSD. My 1TB SSD is wiped clean yet Windows always fails to install on it.

I can see both Bazzite and CachyOS in GRUB but Windows 11 always fails to install. What do I need to do to be able to install Windows 11 on my 1TB SSD? I still need Windows for certain things and I’m getting frustrated with not being able to install Windows onto this SSD no matter what I do. I’ve tried searching and have come up empty handed, although that may be a skill issue.

Any help would be greatly appreciated!
