Like title said, I often heard stories that single boot Linux is better because : a) users want full Linux and b) dual boot often breaks due to Windows updates (forced updates I might say).
I am on a dual boot system myself using UEFI. Installed win 10 first, shrinked the disk, then install Linux along with grub.
I ask because I am thinking of purchasing laptopa with second hard drive. So Win 10 and Linux are on their own. For those going this route, again, does Win 10 updates break your grub?
