Hello & welcome to LQ!
Take it slow, and discover concepts as you proceed.
I'm guessing you were able to boot some 'distro';
commands like fdisk will give you status info.
IF you can get 'live' distro to access LQ (firefox),
you can easily post any&all diagnostic info!
Or just
cli (no gui but network):
Code:
sudo lsblk -o NAME,FSTYPE,SIZE,FSUSED | nc termbin.com 9999
Try some web-searches to see what to look for.
(You could post the search keywords you used, for feedback here)
More details are always useful: model, distro, specifics on what you did, ...
(and even your goals: would VirtualBox.org & OSboxes.org be useful?)
Tons of LQ'ers will be happy to help (so let them enjoy helping you)!
