Acer Spin 5 SP513-52N, dual-boot with Windows 10
I installed Ubuntu 20.04 yesterday, and it worked well, but after a restart today, there was a black screen and the following information:
/dev/sda6: clean, nnn/nnn files, nnn/nnn blocks
I waited for several hours, but there was no progression from the screen.
After searching for similar questions, I tried the following (mostly from the step-by-step from @heynnema in "dev/sda1: clean, ..." This message appears after I startup my laptop, then it won't continue booting):
sudo fsck -f / /dev/sda6 is mounted. e2fsck: Cannot continue, aborting. sudo mount -o ro, remount / mount: /: mount point is busy.
sudo blkid sudo cat /etc/fstab reboot
In Windows 10, unchecked
fast start, in the command prompt window typed
powercfg /h offwhich gave me
Unable to perform operation. An unexpected error (0x65b) has occurred: Function failed during execution.
sudo apt-get purge nvidia*
I got several lines of:
Package 'nvida-xxxx-xxx' is not installed, so not removed The following packages were automatically installed and are no longer required: libllvm9 python3-click python3-colorama Use 'sudo apt autoremove' to remove them. 0 upgraded, 0 newly installed, 0 to remove and 14 not upgraded. sudo ubuntu-drivers autoinstall No drivers found for installation
For the last attempt, I'm not sure if it's because of the wifi disconnecting problem that I had before this. Windows 10 did not have the wifi disconnecting problem.
There were suggestions on using Ctrl+Alt+F2 or F3, but I couldn't figure out when to press that (before GRUB menu? After selecting Ubuntu to boot?).
Edit: Boot-info URL: paste.ubuntu.com/p/N7p5kmgvGG/
Edit 2: Updated UEFI from latest Acer update. Selected shimx64.efi as trusted (from list of fwupx64, grubx64, shimx64, mmx64). Laptop booted directly to Windows10 but GRUB menu didn't appear at all. A check of the partitions showed that Ubuntu was still there (something was taking up the space anyway), then it restarted into Preparing Automatic Repair and stayed there.
Tried several hard shut downs, but still got the automatic repair. Unable to boot into recovery mode using Shift/Esc.
