Thank you for your help guys, i have resolved it finally bymyself
Right now i can boot from garuda grub menu endeavour os
steps which i did
In endeavour os in /boot directory, there was no vmlinuz-linux file, also missing were initramfs files.
- I have copied vmlinuz file from endeavour os
/usr/lib/modules/arch6-12/vmlinuzto/boot/vmlinuz-linux sudo pacman -S mkinitcpiohad to remove dracut package because it was in conflict,mkinitcpio -Psudo pacman -S linuxwhich generated all needed files- removed entry from
/etc/grub.d/40_custom - boot into garuda
update-grub
That resolved issues, and learned something new
