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

I have found it sometimes helps to mount the "Microsoft Reserved" or "Microsoft System" partition before running grub-mkconfig. The os-prober package can be really dimwitted sometimes when it comes to doing scans on its own like that. On Tue, Jul 25, 2017 at 2:07 PM, Junayeed Ahnaf via arch-gene

Hello , I installed arch on my laptop which has 2 hard drives , one is ssd (linux is installed there, also grub), one is HDD(with windows). So, at boot time , I can select either hard disk or ssd and can get either windows or arch. Is there a way for grub to see both Linux and Windows? I tried
