Ubuntu will not try to boot

ru flag

Running Ubuntu 20.04 on a Ryzen 1700, while booting, after the BIOS message it will sit there without loading, there is no loading circle or Ubuntu logo. I am not running dual boot, I have only been able to get into GRUB once and haven’t been able to since

Please follow these steps to try to boot from another kernel: (keep in mind that it is not the final solution but a step to dig into the problem)

  1. Boot from live usb (try ubuntu)
  2. Open a terminal and as root (sudo -s) mount your boot partition in /mnt
    example: "mount /dev/sdax /mnt".
  3. execute chroot /mnt
    When you do chroot now your / starts from what was mounted in /mnt.
  4. edit your grub settings
    the suggested way to do this is by modifying /etc/default/grub on this file change this line to "GRUB_TIMEOUT=15" (this will allow you to see grub menu)
  5. execute update-grub
  6. reboot

After reboot in Grub menu choose advanced options for Ubuntu and try another Kernel (let say 5.8.x)

Whit this step will be able to dig on the next steps.

Also, I recommend you to install grub customizer and set the boot option to previously booted. This can also be achieved by replacing the line

GRUB_DEFAULT="saved"

in the grub configuration.

Good luck.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
