installed Linux Lite - only get GNU prompt

[stevef]

If you can't boot the toshiba from the USB stick using the same method that worked before, then either the USB stick or the toshiba may have failed or changed in some way. Being able to boot the system from USB is likely to be important especially as your installation has failed.

Can you test the USB stick is able to boot in another system and try another bootable USB drive in the toshiba to work out where the problem is?

We can try to tell the system what to boot from the grub prompt.
Only follow these instructions if your system shows the line

Code:

root=hd0,gpt6

from running the set command.
If your system shows something different for 'root=' please provide us with the correct information.

These instructions assume an install of 7.0 as per your sign up information.
If the install is 6.x, 7.2 or 7.4, the kernel numbers will be different from this example.

At the grub> prompt type in

Code:

linux /boot/vmlinuz-

followed by the Tab key. The system should show possible completions for the kernels it finds.
As this is a new install, there may only be one valid kernel and the whole file name will be filled in followed by a space
After the space, continue the command with

Code:

root=/dev/sda6

At this point the 'linux' command should look something like this (though the number may vary)

Code:

linux /boot/vmlinuz-6.8.0-31-generic root=/dev/sda6

Press enter.

Now type in

Code:

initrd /boot/initrd.img-6.8.0-31-generic

It is important that the numbers match for both commands, you can use the Tab to autocomplete.
Once happy, press enter.

Provided both commands were accepted

Code:

boot

followed by enter
