If you’re using a new computer with Nvidia graphics, expect that to be a pain point. I’ve also had issues with the grub bootloader though within weeks I had a mitigation flow. Just remember to have a second computer around to use the internet to troubleshoot, and put important info you need that you work on on the PC on an attached thumbdrive also. This way you don’t have to worry about losing data. Makes the migration a lot more peaceful.
