I installed the linux lite ISO on my notebook since my HD had a problem
Did you re-use the HD with the problem for the linux lite install ?
If you re-used the disk, can you tell us
What OS was on it before it had a problem?
What was the problem with the HD ?
but every time I turn off my notebook it looks like I had formatted it, like using it for the first time.
Did the LL installation appear to be ok ?
Can you tell us what you see when you re-boot after the install ?
If the HD really looks like it has been formatted that would mean the BIOS is saying something like 'please install a bootable OS'.
