He's just guessing.  Try

    sudo mount -o remount,rw /dev/sda1

Almost certainly not.  You do not need to be able to write to a disk
to run a program from a file on that disk, for one thing.  For
another, since (under Knoppix, I guess?) it's mounted rw, you probably
don't have hardware problems that prevent mounting rw under your
HDD-based installation, either.  You won't be able to find that out
until you successfully boot that system, though.

The problem is that somehow /bin/sh -> /bin/dash has been either
trashed or set to non-executable, and the kernel refuses to load and
execute it.  You need to su and reset those permissions on dash:

chmod 0755 /bin/dash

The question is how to su.  Several suggestions were given.  Have you
tried those?  What was the result, including error messages?
