[Solved] Grub configuration (grub.cfg) no Windows 8 menuentry

Hi! How should one generage grub.cfg for Windows 8 on old hardware? A PC is over 4 years old. Grub-mkconfig gives nothing for a ntfs partition with Windows 8.

Re: [Solved] Grub configuration (grub.cfg) no Windows 8 menuentry

I ran grub-mkconfig on a system with Windows 10 installed on it today and it successfully detected and provided a menu entry for it (albeit identified as "Windows 7").

Did you install GRUB to your MBR?

# grub-install --target=i386-pc --recheck /dev/sda

https://wiki.archlinux.org/index.php/Be … guide#GRUB

If you have done this already, please post the output of:

# parted -l

EDIT: I'm presuming you're using a non-EFI system.

Not an Installation issue, moving to NC...

You do not have the main Windows partition on your system, just the boot partition.
There should be a second ntfs partition with no boot flag...

EDIT: I think so anyway -- that's how my Windows partitions show up on an MBR BIOS system.

Got it solved, my gratitudes. I guess os-prober installation helped here.
