I have an Ubuntu 20.10 system in a dualboot with Windows 10. It has been working for about the past 8 months, but suddenly today it no longer boots from Grub. Immediately after selecting Ubuntu from the drop down menu my laptop switches to an illuminated but black screen and sits there forever. My laptop is a Lenovo Yoga 720 15". The longest I let it sit without powering it off was 30 minutes. I tried to use boot-repair on a live-USB, but that did not fix anything. It gave me the following link: https://paste.ubuntu.com/p/QfkxbrnmNX/
In Grub I can select advanced options for Ubuntu. If I select Ubuntu, with Linux 5.8.0-59-generic only two lines display on the screen:
Loading Linux 5.8.0-59-generic ...
Loading initial ramdisk ...
The same result occurs when in advanced options if I select Linux 5.8.0-59-generic(recovery).
I can successfully boot the system only when using 5.8.0-55-generic.
Has anyone faced this issue before, or has any recommendations on how to fix it?
Any help is greatly appreciated!
Update #1: I am currently using this workaround. It means I have to press the return key twice on boot-up instead of just once, How can I boot with an older kernel version?, but it looks like I may have run across a bug.
Update #2: Running suggested comment and output:
