I've looked for a recent answer I can understand (absolute novice) but nothing seemed to address my specific problem.
My system is set to boot Ubuntu first (see setup screen image). The second boot is Windows 11 home, fully updated as of 2024/09/21.
Each time I switch on I get the following:
Failed to open \EFI\UBUNTU\grubx64.efi - Not Found
Failed to load image __: Not Found
start_image() returned Not Found, falling back to default loader
Failed to open \EFI\UBUNTU\grubx64.efi - Not Found
Failed to load image __: Not Found
start_image() returned Not Found
It then boots into Windows.
Please explain like I'm a kid, how I can make my laptop boot into Ubuntu again?
I should add that I bought it a while back as-is, and I have no install disk for either Windows or Ubuntu.
