Not long ago i clean installed Windows 7 on my laptop and the installed Antergos for dual-booting. The hole install-process went by without any problems, but when i tried to boot into windows usig grub, the screen just showed a bunch of horizontal, purple/blue lines and got stuck there. Some times (not often) windows manages to boot through grub but one once. If i restart and try again, i get the same dreadfull screen. When i now read dual-boot toturials, i see that some of them are saying that i should have put the /boot/efi on the ESP-marked partition that were generated by Windows. I did not do this… I only created a swap and a root partition, not a /boot partition. Antergos runs just fine, and when Windows boots, it also works just fine.
My question is now: did that mistake create the problem i now have, or are there some other reason?
In advance, Thanks!
