Windows or EOS can't be used

General system
1

Hello.

Since a few months i’m using Windows stand alone. Yesterday i wanted to add EOS again, but failed. The Boot Option should be available, but isn’t. So i setup the whole entire sYstem fresh. First Windows then EOS. Windows alone works fine and Boot Option is windows. But after installation of endeavourOS the boot option is only Linux. Did chose install alongside.

Same procedure other way. First Linux then Windows. Same Problem.

Do i have to use efibootmgr?

Thanks

Thanks for answer, but it doesn’t work.

I added GRUB_DISABLE_OS_PROBER=false to the grub file and regenerate it through command. Reboot the system and nothing changed.

Please post the output of the following commands:

sudo parted -l

sudo os-prober

efibootmgr -v

Install os-prober

sudo pacman -S os-prober

and regenerate your grub.cfg (update your grub) again:

sudo grub-mkconfig -o /boot/grub/grub.cfg

You can’t use Efi on that machine.
