I’ve made a copy of all windows partition.
I can access to my windows partition with uefi/bios (windows boot loader).
and grub load EOS when I boot on the disk in uefi/bios.
I cannot see the windows partition doing
sudo grub-mkconfig -o /boot/grub/grub.cfg
despite I’ve do a frech install.
May I reinstall windows ? and EOS after. How to repair grub-loader ? Do you think tools like rEFIned help me in this case ?
Tell me what information do you need.
If BIOS and if this is a new install, backup your personal data and reinstall in UEFI mode. Make sure that you disable CSM in your firmware settings. That is, you should only have UEFI boot mode enabled.
