Re: Error when installing ubuntu 12.04
Are you trying to install to a PC that has Windows installed -- and is hibernated? In that case, it would most likely be using sda1 and won't let you access it.
Otherwise, do you have some other OS running using sda1 that is hibernated or in sleep state?
Or, is sda1 a partition that was in use and you simply powered down without gracefully shutting down?
Ubuntu 16.04 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
