[I DON'T NEED A ANSWER ANYMORE.. I DELETED MY WINDOWS VOLUME AND IT WORKS TO INSTALL NOW BUT PLEASE READ THE REPLIES]
So I'm installing ubuntu 20.04.3LTS right now off a USB stick i flashed with balena etcher on windows 10. but the installer been hanging for like a hour now.. when I try to quit it doesn't give me the option to quit its just a blank white screen and idk if it's safe to just kill the task im not going to.
So can I reboot or will that mess up my system or what? I can't go back in the installer either to disable the download updates while installing (which seems to cause alot of problems with other people , maybe could be my problem to but I can't go back)
FYI I'm on the installation type page and I'm dual boot windows 10 and ubuntu. Used to have pop os on here now I want to switch to ubuntu, overwriting that pop os drive. It says on the page here "This computer has multiple operating systems on it. What would you like to do?" when I click 'something else' , nothing happens and I don't have the option to go back or to continue. The only option that's not greyed out is quit - in which it doesn't respond its just a white window "Quit the installation?" with nothing else
Can I reboot during an install or will that corrupt some files or etc, as i can't proceed or go back OR QUIT in the installer. Btw, i deleted the pop os partitions
