Actually with that tip (that I discover before he posted it) you enter into "windows safe mode", it's a mode that charge the most basic drivers to give you access to do kinda of something (for that reason you see a black screen instead of your wallpaper).
I was able to copy my files from my laptop to an external hardrive from the funtion "Run" (if you type win+r it appears in a lower corner and you can click browse to see and search your files because in this mode explorer.exe or the file explorer does not
exist or doesn't run) just by clicking the browse button and copy folder by folder to the drive. Be pacient, it takes a while and it doesn't show you any visual feedback, just "the sand clock" that means thats is making a task and if you click many times it
will say "the program is not responding" for the same reason. When it finish the only thing you will notice is the new folder in your external device.
Take in mind that with this method you can only copy folders because how is from the funtion "Run", it is seafching for .exe archives and not regular ones so if you have some archive in particular that you want to extract, you need to copy the entire folder
that contains it.
The only problem that I have doing this is when it hits a big archive (in my case a game image that size 60GB) it says because of it size it cannot be copied (I guess it's because of the load of just the basic drivers) so that archives will be forever gone
or at least for now.
Hope I help you (specially the thesis guy) and you can now understand a little bit more of what's happening.
And yeah, for the record, stupid untested update haha :(
I think mine got a little different. Not in "windows safe mode". Actually, the computer is completely off and sometimes "Lenovo" flashes on the screen.
How do I get in this "windows safe mode"?
