Hello, I am a Computer Support Technician student and have been experimenting with many distributions of Linux. I'm not a complete novice but I am very far from an expert and I'm hoping I can get some help with this very furstrating problem I've run into.
So I recently decided to try out Solus, mostly because I wanted to try out the Budgie desktop environment and just to try out a new distro. So I downloaded the latest version ISO, burned it to a USB flash drive, used that to boot into the live version and proceeded to install it, replacing a Linux Mint installation I was already running. Everything seemed to go fine during the installation, but when I tried to boot up after, I got an error saying it couldn't find an operating system. I made sure the everything was correct in the boot order, and it was.
So next I booted into an old drive with an old version of Ubuntu on it and tried to use that to format the other drive with Solus on it, but it was an old drive and I didn't know the root password needed to perform the formatting. So I decided to go ahead and try installing Solus on this old drive, figuring it was a problem trying to install it over Mint or something, I didn't think it through much. I ended up with the same exact situation, can't boot, system can't find operating system.
So then I figured the problem was Solus, so I tried installing Ubuntu with Budgie on the first drive, everything seemed to go fine, same problem.
So then I tried to using the USB boot stick with Ubuntu with Budgie on it to use Boot Repair, thinking it was a problem with the GRUB loader. No success there either.
Thinking maybe, somehow, it was Budgie, I tried installing lubuntu (Ubuntu with LXDE) on the first drive and still the same problem.
So that's where I am at the moment, I really hope someone can help me figure this out, this problem has been tedious and frustrating.
Thank you for any help you can give.
