I have a dual boot with Windows 10. I was unable to boot Ubuntu from disk. I have a bootable USB stick and that worked. I booted from the USB and then booted a recovery Ubuntu option in Grub. Then, I was able to get into my Ubuntu partition. I was updating my system when the machine just shut down. After which, I ran Boot-Repair.

Now, I can boot from my Ubuntu partition, but once I enter my password, the screen is all messed up and I can not Login. It doesn't seem to recognize my password. Also, now, I can not boot from my USB Ubuntu Stick. I made a brand new Ubuntu ISO image and that will not boot either. (A reinstall previously fixed the screen problem.)

I have tried changing the boot order in the BIOS. That does not help.

The link to the Boot-Repair log is above. Any help would be greatly appreciated.

    Any abnormal shutdown corrupts system. You need to run fsck on any ext4 partitions and may need chkdsk on NTFS partitions from a Windows repair disk. askubuntu.com/questions/642504/… And then if in middle of updates you need to boot recovery mode and finish updates or chroot into system to finish updates. askubuntu.com/questions/253243/…

I can't explain what happened exactly. I was studying my machines operation and at one point, while trying to login, I got the same messed up screen but, after a while I did get into my machine. The icons (like the wifi icon) were blanked out and I could not access my Windows drive but, I was able to run an update. After the update, the system seems to be working fine; I can boot from my USB stick and; access my Windows drive from my Linux partition. But, I still cannot boot Ubuntu from my DVD.
