Why is Grub-mkconfig not finding my partition?
For some reason, grub-mkconfig -o /boot/grub/grub.cfg is not finding my windows partition. I have my UEFI partition mounted to /boot. I have installed grub with grub-install –target=x86_64-efi –efi-directory=/boot. I can see /boot/EFI/gentoo along with the windows directory. Any ideas how to make grub-mkconfig see my windows 10 partition?
Can you use GRUB2 to detect other operating systems?
In most instances, this will enable GRUB2 to automatically detect other operating systems including Windows 7, 8.1, 10, other distributions of Linux, etc. root The GRUB2 (and optionally sys-boot/os-prober) installations do not automatically enable the boot loader.
Why does GRUB2 not install the boot loader?
The GRUB2 (and optionally sys-boot/os-prober) installations do not automatically enable the boot loader. These only install the software on the operating system, but to install the boot loader to the system itself (so that it is used when booting the system), additional steps need to be taken, which are covered in the Configuration section.
Why is grub not able to find windows?
Grub searches for EFI entries, not BIOS entries. But, there are none. So Grub can’t find Windows. Alright awesome thanks. My understanding of boot loading is pretty poor so I appreciate you laying that out for me. So basically what I am gathering here is that something needs to be reinstalled…
What to do if Grub does not detect Windows?
There is a Windows tool: mbr2gpt which can convert your MBR to GPT. After doing so (and booting via UEFI) os-prober and finally update-grub was able to find my Windows installation and added it to the boot options of grub. Follow these steps if os-prober shows Windows, but GRUB does not. # Disable os-prober by default due to security reasons.
Why does Grub boot Linux but not win 10?
After the installation GRUB only offered to boot Linux but not Windows. I found the video solution for windows 10 missing from grub menu and the forum thread Grub not recognizing Win10 after Update/Repair, but unfortunately neither worked for me so I used a combination of these two to resolve my problem.
Where does the boot folder go in Grub?
If you didn’t specify a –boot-directory some_path (not –efi-directory) option, it would be under /boot, otherwise it would be under some_path. But where exactly /boot or some_path refers to can vary.
