I installed KDE neon today, i had an error telling me that the installation couldn't be finished, so i left KDE neon by click on shutdown option and just power on my pc to boot on Windows, but my pc boot on KDE neon it worked well, but when I wanted to restart my computer to go on Windows, it wasn't there in the boot options.
So I tried to repair GRUB but it did anything, so I went to uefi settings when I booted so I could change the boot option and boot on Windows. So here I am asking help because i'm Lost with that.
Should I try to delete KDE neon partition and delete the boot option and try reinstall it ?
Thank you for your help.
