/bin/sh: bad interpreter
 

Hi,

After i did a frustated attemp to install bash in chapter 6(one of the partitions i made was too small), i tried to recompile, but found that now it was looking for the interpreter in /bin/sh instead of the interpreter in /tools/bin.

How do i return this to the normal value?

Which book are you following? I think there was a bug in in book 5, which didn't have the +h in the first chroot command. The last line of it should be

/tools/bin/bash --login +h

The +h stops the shell remembering where things are so it just searches the $PATH for the meaning of commands.
