Beware when re-installing Linux in dual boot system!

[Dookus]

There is a plethora of free imaging programs available for download, some are even cross platform, I use Macrium Reflect free for Windows, If anyone does not own, or has not made recovery disks for their Payware OS, whether via the program that ships with your Machine or via a third party option, it "is" a very good idea to so so, installing Linux as with any duel booting scenario may leave you with a broken system.

Tasks such as moving your OS to a new HDD, upgrading to a SSD, any time you may need to replace or install a new piece of hardware, making registry changes in Windows or making sure you don't have to re-install every program and make every tweak or change in Linux or other OS, again these programs will save your ass!
