Ubuntu dual system does not have a bootable device solution

After installing dual systems with Ubuntu, the boot prompts the error no bootable device found, no bootable device. Obviously this is because the boot settings of UEFI are destroyed during the installation process, so it is necessary to fix the boot device of Ubuntu. Here is a solution to the problem that Ubuntu dual system has no bootable device.

Step

and enter the boot off the power settings. I need to quickly press Fn+F2 on the Acer R13. If you use a solid state drive, you have to press it very fast because the SSD starts up very quickly. It depends on your manufacturer, you may want to use Del or F10 or F12.

Step 2

In the boot settings, make sure Secure Boot is enabled. It is in the Boot tab.

Step 3

Go to the Security tab and find "Select an UEFI file as trusted for executing" & rdquo; and hit enter .
Fixing No Bootable Device Errors

Deliberately, this step is to add a UEFI settings file (generated when Ubuntu is installed) to your device to a trusted UEFI boot. If you remember, the main purpose of UEFI boot is to provide security. Since (possibly) Secure Boot is not disabled, the device will not attempt to boot from the newly installed operating system. Adding it to a whitelist-like trusted list will cause the device to boot from the Ubuntu UEFI file. Previous123Next page Total 3 pages
