- I installed Ubuntu 20.04 in dual boot. I removed Windows 10. No problems.
- I installed Katoolin (no problems).
- After updating Ubuntu and rebooting the system this happened:
BIOS:
Kali GNU/LINUX
Advanced options for Kali GNU/Linux
UEFI Firmware Settings
If I choose Kali GNU/Linux, only appears the Ubuntu symbol.
If I choose others, it fail to start.
I can't have the privilege to modify anything If I choose the UEFI option.
When the recovery mode was working, I use this command:
Ctrl + Alt + F2
sudo apt-get reinstall ubuntu
Nothing changed.
Then:
sudo apt-get autoremove --purge
I used it to remove Ubuntu and Kali (a stupid mistake). At the time I thought that would be the solution from the boot order.
