Hi guys, a month back I rolled back to Win 7 due to some issues mainly slow boot. I upgraded back today and the issue still remains. I have tried many of the fixes given online but with little success. In BIOS settings, i enabled legacy boot only, after which I observed that the black screen stayed for only 45 seconds compared to the earlier 1 minute, but the loading time to desktop from login screen was the same i.e. 1 minute. Compared to this Windows 7 loaded to desktop from OEM logo in just a minute. What exactly happens in between the windows logo, the black screen, the login screen and then to desktop? I understand that a clean install may fix it, but until i do that, i wish to explore other options to try and find out what makes it boot slow to this extent.
