Asguardian says to Ubuntu 台灣社群I need help. I have dual boot windows and ubuntu. I want to expand the EFI System partition and reinstall windows, not going to touch installed ubuntu at all . So, my question if I just delete Windows, reserved(of windows) partition and expand the EFI then everything will be fine like already installed ubuntu? Or I have to something else too? And How can I backup EFI partition and files of it using ubuntu? Thanks.at Mon, Dec 16, 2019 7:51 PM
