Hey guys, I'm trying to install BT4 using the guide posted in the HowTo section and I've run into an issue. I formatted my drive and everything runs ok up until I get to the command

root@bt:~# cp --preserve -R /{bin,dev,home,pentest,root,usr,boot,etc,lib,opt,sb in,var} /mnt/bt/

It runs for a bit and then freezes. Sometimes it throws an input/output error on the program icons for Crystal, and sometimes it just freezes.

How can I make sure that this command executes successfully?
