@chill3er Hey ! Another day and another answer to my question hehe
So, first of all in my case i didn’t know but my windows drive (sda) was MBR and not GPT (which is weird cause my mobo is UEFI) so thats why i didn’t have any EFI partition made by windows and thats also why i couldn’t manage to add windows to grub’s menu (i think so).
I completly uninstalled Antergos, cleaned my SSD with diskpart on windows, then i downloaded a software called AOMEI Partition Assistant to convert my MBR disk to GPT without losing any data. (theres also a free tool called gptgen, but i didn’t want to mess up with it). Basically it rebooted my PC converted the disk then created the EFI partition.
After then, i reinstalled Antergos, pointed /boot/efi on the correct fat32 EFI partition made by windows, did the usual home,swap,root and installed grub2 on windows disk. Rebooted after installation, i had the usual bug with my nvidia card so i followed the instructions from got-it-man’s post above, rebooted again and I was on Antergos’s desktop !
Now the next step was to add Windows 10 to grub’s bootloader. I ran a shell, used:
which gave me :
/dev/[email protected]/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
then I did:
sudo grub-mkconfig -o /boot/grub/grub.cfg
It found the windows bootmanager and added it to the grub menu
Now i’ve got a working dual boot with windows 10 & Antergos ! Hope this helps someone else !
yep thats what i did, but do not format it during antergos installation do not check format for that part otherwise it will screw up your boot files for windows.
edit: also i think grub-update won’t work with antergos because its based on arch linux the right cmd is : grub-mkconfig
