Not long ago i clean installed windows 7 on ,y laptop. I then installed Antergos for dual-booting. Then windows chould not boot so i used boot-repair to fix it. When i now go in to grub to boot windows 7, I usualy get a blue/purple screen full of horizontal lines and it gets stuck there. But some times, when have not tried in a while, it randomly boots in to windows when i select it in grub (Antergos boots just fine btw).
Does anybody have a solution?
