i have a laptop with only linux installed and use redo backup. have no problems. i will be purchasing a new laptop soon and am sure it will come preinstalled with win8. i am going to delete and install my linux using the redo. do i first have to reformat to ext4. or since i have the redo backup can i just install. or would it be better to download linux burn a cd and install and then update my new laptop with my most current redo backup. tks
