Ubuntu 19.04 Freeze at loading DELL E6430 i5 - nomodeset didn't work well
Solution 1:
I found solution:
When GRUB is open click E and change from "quiet splash" to nothing, just delete. After that Ubuntu will open.
Open terminal and write "sudo nano /etc/deafult/grub"
on line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" delete "quiet splash". After that it looks like this GRUB_CMDLINE_LINUX_DEFAULT=
save this and write in terminal: "sudo update-grub"
Restart and after that it's ok. You can use windows and Ubuntu as well. You'll do't see any errors.
