I have a dual booted windows 10 and ubuntu 16.04, Asus republic of gamers, GL753V, one of the best gaming laptops, Windows OS is installed on SSD.
After selecting windows from grub menu, I see loading spinner on black screen. This thing for the past week or two is lasting between or 15 minutes from shutdown, and around a minute from hibernate I think.
In other words, if I were to shutdown or restart windows, then it would take longer to get to the login screen than windows XP on pentium 3, for real.
Once I get to the login screen, everything becomes extremely fast, how to know why getting to login screen is getting so long?
I have only 3 programs running on startup, Logitech mouse drivers, Avast and windows defender which has low impact since it's not doing anything. Very few programs are installed too on this pc.
I disabled fastboot, the problem is the same, I also trying restarting and shutting down again, the same problem, I also did full scan using avast free version and malwarebytes premium version, No malware found, the problem still exists.
