I have a Lenovo Legion Y570 G50 with an i7@2.2 Ghz., 32GB of RAM, and a 1TB SATA hard drive. I just recently upgraded the operating system from Windows 10 to Windows 11 Pro. The problem is that the installation process gets stuck at the 61% mark. Also, the upgrade process seems to proceed at a turtle's pace! Can anyone give me at least a hint as to what the problem is and how to correct it? Thanks in advance!
