@Patio Well for me there is reason to delete the windows 10 os,some reasons are because i dont like windows os because i only use linux and finally because windows os is not secure and doesn't have privacy. Reasons why i dont want to have an operating system installed on my computer because im only going only use bootable operating systems like mx,puppy,tails not just tails and the reasons for this is for security reasons for example if my laptop gets stolen my information wont get lost because ill have my bootable usb os's on my necklace and its also my preference :/ @Salmon Trout Yes thats exactly what im saying. How do you install Gparted on tails?
