how to hide 100MB system reserved partition?

Simply Remove the "Drive Letter" of system reserved partition. :)

2. Should I ignore the message when trying to change the "Drive Letter"???
3. YES!~ ignore it and restart the windows > Log Off > Restart :)
Got the foldrs back after a restart, then did it Tanvir247's way. It worked!! THANKS Tanvir247 & Sasha.
