Hey everyone! 😊 I'm trying to get my GRUB bootloader in CachyOS to recognize my installations of Bazzite and Windows 10. Here's my setup: I have an HP Z4 G4 workstation with a Xeon w-2145 processor and a 1080 Ti graphics card, featuring two NVMe SSDs in the motherboard and two more on a PCIe card. My first SSD is 1TB with Windows 10, and the second one is 2TB. Bazzite is installed on the 900GB partition of that SSD, and I later installed CachyOS on another 900GB partition there as well. The problem arises when I boot into CachyOS; its GRUB bootloader doesn't show Bazzite or Windows 10, unlike the bootloader for Bazzite, which shows all options when I boot into it. I really want to edit the CachyOS GRUB to include Bazzite and Windows. I've found some information online but am not sure how to apply it to my situation. Thanks for any help!

You can solve this pretty quickly! Boot into Bazzite and run `update-grub` in the terminal. This should automatically find and update the entries for Windows and CachyOS in GRUB. If you want to stick to the CachyOS version, make sure that the `os-prober` is enabled in its config. Just uncomment that option and run `update-grub` again!
Thanks for that tip! I also had issues with Fedora 42 based Bazzite, but running `just regenerate-grub` did the trick for me. It found both Windows and CachyOS and updated the GRUB entries. Now I can see all my OS options. Appreciate the guidance!
