1 year ago if you use fedora silverblue, you might need to modify _99brunch with:
replace [your path to chromeos].img with /home/[youruser]/path to chromeos img

**************************************************************replace [your path to chromeos].img with /home/[youruser]/path to chromeos img
but from experience .. install Brunch as main OS and use LinuxLoops .. https://github.com/sebanc/linuxloops and more exact link https://github.com/sebanc/linuxloops/blob/main/Install-with-brunch.md#1st-method-using-brunch-grub
at least for me it's much better.. better performance. on both .. linux and chromeOS
i followed dualboot guide to create chromeos.img and added /etc/grub.d/99_brunch but grub says unknown file system while booting. on trying grub cmdline cannot access (loop,gpt7) or ROOT-C partition via grub its chrome-os file system any way to fix it . can we make ROOT-C partition ext4 instead of chrome os root partition type
