It want boot from USB or the DVD drive.
I can play DVD’s or CD’s, so the drive is OK.
I don’t know what could have changed my boot sequence.
I found this article online but have not tried it yet.
How to change the boot sequence
efibootmgr -v
This will display all boot devices on your computer, and resemble something
like:
BootCurrent: 0000
Timeout: 2 seconds
BootOrder: 0000,0004,0005,0003
Boot0000* ubuntu HD(...)/File(\EFI\UBUNTU\SHIMX64.EFI)
Boot0003* Hard Drive BBS(...)
Boot0004* UEFI: JetFlashTranscend 32GB 1100 ...
Boot0005* UEFI: JetFlashTranscend 32GB 1100, Partition 1...
The first line shows the current device that was booted from, the third line
shows the computer's current boot sequence, and the following lines list each
bootable device.
Take note of the numbers such as 000, 003, etc. In this example, we can see the
current boot sequence is the Ubuntu installation, followed by the hard drive,
and the two different partitions on a 32GB USB drive.
Change Boot Sequence
Choose your new boot sequence by the device numbers, and change your boot
sequence with the command:
sudo efibootmgr -o 5,0,4,3
Using the above example, that command would change the boot sequence to try the
USB drive first, followed by the main Ubuntu installation.
It's that simple, and you can now change the boot sequence on any Linux
computer via terminal without scrambling to get into the BIOS when first
powering on the computer.
This assumes that you have a non-legacy BIOS! :)
