Current setup is A dual bootable system with Windows 7 on a SSD with Win XP on secondary 500gb WD drive ( that has 300GB of backup files) I also have all my games on 3rd 500gb WD drive (currently 150GB used). Now what I am intending and would like some input on is this: I am Installing windows 10 and want to have a tri-bootable system but I am currently unsure if I want my SSD to host Win 7 or 10. My main usage will be through Windows 7 as most of my gaming and work related programs currently are not fully compatible with Windows 10 but I do not want to have to clone and swap drives at a later date when Windows 10 is more well supported by my job. Any ideas and advice would be appreciated.
