Do your screwing around with live CDs. 
If you don't mount hard drive partitions, 
then when you screw up, you're only a reboot away from where you were. 

The use of live CDs is a recurring theme. 

Ubuntu has one https://help.ubuntu.com/community/LiveCD
Knoppix is the granddaddy of live CDs. 
Knoppix disks belongs in your bag of tools.
