Hi Junayeed, "grub-mkconfig" operates on the files in "/etc/grub.d", as per the following: https://wiki.archlinux.org/index.php/GRUB#Windows_installed_in_BIOS-MBR_mode and the idea of a "menuentry" is further discussed in: https://www.gnu.org/software/grub/manual/grub.html#Multi_002dboot-manual-config But I can't say if GRUB is the best way for you to multiboot. It could be useful for you to explore the difference between GRUB and syslinux. According to the documentation, either should work for dual booting with windows: https://wiki.archlinux.org/index.php/Dual_boot_with_Windows But the documentation does not make any suggestion as to which works better. That is probably a matter of personal preference anyways. And also, be careful, if you start asking too many questions, I'm sure someone will call you a "help vampire".
