Problems with my Dual Boot after Installation
Hey erverybody, i switched from Nobara to Bazzite to couple of days ago.
I have Bazzite on my NVME and have a Win10 Installation on a Old SSD in my Case.
With nobara i always had the option to boot in nobara or in win10. now this option just disappeared.
Bazzite sees the device, but i cant start from it.

Open the terminal and run
ujust regenerate-grub and see if it picks up your Windows install. If it does, your next reboot will give you the option to boot Windows or Bazzitei did it, restarted my system but it doesnt changed anything.
is it possible that i messed up with something while installing bazzite? i cleared my whole nvme, just to have a fresh restart
Are you able to boot into Windows from the BIOS? Might be worth running
sudo fdisk -l and seeing is you can see all your Windows partitions
My setup looks like this, I have a shared EFI and I can see the Windows partitions in /dev/nvme0n1p2 and /dev/nvme0n1p3.
no, thats the thing that confuses me most. in the past i could push F11 and choose the disk i wanna boot from.
now i realized i just can see the disk in the partionsmanager, but not in my fileexplorer.
i probably deleted more than i should have. i just copy this disk and reinstall windows after the holidays.
even with fdisk the device isnt there
oh, sorry. fdisk shows the device like this:

i have this option, but the system wont boot.
i have no idea, when i booted it the last time. maybe the problem exists a long time and the installation of bazzite wasnt the tipping point. i have no idea.
i take the ssd out and put it in a case. so i dont lose the data. after my christmas holiday i will buy a second NVME and put windows there.
but before i start such a thing: should i install bazzite, or windows first?
i would like to have a boot loader, to choose which one a wanna start. but the standard option should be bazzite.
I usually run
ujust regenerate-grub and then I can select between Bazzite and Windows from the grub boot menu. In your setup with both on different disks, you can install either one first. However, when you install Windows, unplug all other drives, as Windows likes to put it's EFI partition on the first drive that it finds rather than the drive that you install it on. Do the same with Bazzite and unplug the other drive. That way you are guaranteed to not have a shared EFI partition or either install messing with the other install. Have much less issues this wayok, thanks. so i will install both with only one connected. sound like a solid idea to stop anyone from messing around with the other one.
and i change my bios to uefi again?
Yeah when you do the installation, make sure that you only allow EFI boot. That will also save you from ending up with Windows or Bazzite installed with CSM
okay. thanks a lot for the help.
i will try this in the new year. when i ran into problems i will come by again.
have a good time with christmas and hopefully not to much family trouble
Thank you! You too 🙂
