I have my bootable USB, my secure boot turned off, and have managed to boot into 'trying ubuntu' and begin the install process.
however when I reach the tab that asks how i would like to install for example erase everyting and install, something else, etc. It says that no other OS is detected on the computer.
My worry is that if i proceed with something else and install anyway GRUB wont allow me to boot into windows 8.1.
Anyone encountered this?
