Hello All As a prelude, I am reaching capacity on my internal 256GB SSD and so am wanting to utilize the 1TB SSD I have. I'm running Ubuntu Mint on an ASUS 15" laptop, version 20.04. I successfully cloned my 256GB SSD to a 1TB SSD. I used the entire space as one partition. When I check with GParted I see that is actually the fact. However when I boot the laptop with the 1TB SSD as a USB drive the machine boots from that drive automatically. When I check the BIOS on booting I only see the 1TB SSD as a Boot option if it's connected as a USB drive, not the still installed 256GB SSD. If I unplug the 1TB drive the laptop boots from the internal drive. In the BIOS I can see in each instance the specific drive (the 1TB USB drive or the internal 256GB drive) as the only option to boot as opposed to seeing the external 1TB drive and the internal drive and being able to choose. Why the machine boots automatically from the plugged in 1TB USB drive is an unknown to me. At least the drive is cloned and will boot. Before I replace the internal drive I'd like to have that full 1TB available. If I can make that happen then I can upgrade the distro and replace the internal drive with it. Any ideas on how to get those almost 750GB on the 1TB drive to be accessible? Thanks for any help! --
