OS not booting in VirtualBox

[firenice03]

@catgrep
While in the VM (captured) hitting ESC while booting will display LL boot process - Hitting ESC again display the grayed/ circle loading screen --- this is after boot options/grub (could be very quick to this point)

If you didnt  see the grub screen = Close the window, dont save state - power off... Then boot again Grub should display...
Ubuntu is likely the top option - Choose Advanced Options for Ubuntu --- Could say Linux Lite vs Ubuntu and hit ENTER
You will have various Kernels and Recovery to choose from ...

Try the upper most Recovery see how it fairs - else try the previous (2nd most current) kernel version (non recovery) this should be the state it last booted, prior to updates.

 Post back success or not...

Check disk etc etc.. you can try rerunning updates and see where it crash....


This is a RECOVERY option
Snapshot is within VirtualBox - if you created one..
or are you referring to TimeShift? - within LL --- you would need access to terminal/tty

Hi!
Can you be more specific?

I hadn't run my Linux Lite VM [...]

What you mean by Linux Lite VM?
Are you running Linux Lite as a guest OS, or as a host OS?
Or, maybe both of them?
In the last case, which OS hangs? The host? The guest?

[...] I installed all the updates and rebooted, now I get a black screen and a blinking cursor before it loads the logon screen and will go no further.

Again, be more specific: what OS did you update? The one you are running VirtualBox on (the Host)? Or the installation you made IN VirtualBox (the Guest)?

[...]Is there a keyboard shortcut to show the bootloader menu or enter a safe/recovery mode so I can restore from a snapshot?  [...]

Keyboard shortcut
Yes, there is. Read the Manual. It's either SHIFT (BIOS) OR ESC (UEFI)
Specifically, read this:
https://askubuntu.com/questions/16042/how-to-get-to-the-grub-menu-at-boot-time

Snapshot
Again, it is very confusing... What snapshot of what OS?
Please, post more details, then we can figure out what is happening and mostly, where precisely.

[...]this catastrophe[...]

What catastrophe?
Nothing is a real catastrophe, as long as the machine is OK and the storage media works as expected.
We'll find a fix!

Best regards!

Don't have VirtualBox myself, so guessing but my first thought would be lack of resource (maybe disk space).

Did the updates complete ok ?

Can you provide a bit more information about what happens when you say it

will go no further

please ?

If you get a login screen, can you try pressing Ctl Alt F2 to see if TTY access works?

I hadn't run my LinuxLite VM in several months, so when I booted up, there were a lot of updates.  I installed all the updates and rebooted, now I get a black screen and a blinking cursor before it loads the logon screen and will go no further.

Is there a keyboard shortcut to show the bootloader menu or enter a safe/recovery mode so I can restore from a snapshot?  Any help recovering from this catastrophe is greatly appreciated.
