That's the basic thing you need to open a command prompt where the python directory is installed hence it won't work.
I copy paste this whole line after changing the info with mines or do i need first to run --recover then --recover device=D etc?
No, you need to point it to where your
--recover size=50Gio
This is the size of the D device? So in your case it was a 50gb hard drive? The size of the btc hd is 153gb so should I put --recov_size=153Gio ?
Yes you need to use --recov_sie=153Gio if the size of the partition is 153GB
