Post by pinneriteI cannot get into the grub menu in order to boot on an earlier kernel.
I have holding down Esc or Shift while booting up but it goes straight
to the BIOS screen.
I left a crie de coeur on the Linux Mint forum but I wanted to try for
the earliest answer.
TIA
How about the Boot Repair CD ?

"2. To get to the grub menu, which we will use to boot into recovery mode,
you must press a particular key during start-up.
For most people, you must continually press the ESC key on your keyboard during start-up [UEFI]
If you are running an older, non-UEFI system, you must instead press the SHIFT key continually.
Once you are certain of the key you need to press, turn your Ubuntu device back on and begin
pressing the correct key. If you see the Ubuntu splash screen, you must try again.
"
The difference being, that SHIFT is a modifier key.
Whereas <esc> is a regular matrix key press, which means
you might have to fiddle/hammer it.
Also, not in this particular case, but I've run into
instructions to press a particular key, and the particular key if
pressed too early, is judged to be a BIOS-modification key. This
means your timing has to be good to extremely-good to get the
actual proper response.
The shortest design window I've seen
for a "key-press", is a timing window only one second wide,
on an Insyde-branded BIOS. I can never nail that on the first
try, and it takes a minimum of two tries.
It would be nice, if a visual indicator indicated "start of timing window"
and "end of timing window", so the user can learn the timing needed.
But where would the fun be, if they made it too easy.
