Setup/Goal:
I have two SSDs, one which has Windows 10 on it and one which runs Ubuntu. Previously, I set my boot order to go to my Windows SSD first, which would run Windows without a Grub screen. When I needed to use Ubuntu, I would switch the boot order and a Grub screen would appear where I could choose either Ubuntu or Windows. These are the settings I would like to return to.
Backstory:
I deleted my Ubuntu partitions with the intent to reinstall (I now understand that was my grave mistake). I deleted Grub and the computer was left unable to boot. I ran the boot-repair tool and the result was that my Windows drive would boot to:
error: no such device: (series of letters and numbers).
error: unknown filesystem.
Entering rescue mode...
grub rescue>
and my Ubuntu drive would once again boot to Grub with both OS's.
I tried to run the boot repair again (likely another mistake) to fix my Windows drive, which leads me to my current problem.
Problem:
When I boot to either drive, I am presented with a Grub screen that does not contain an option to boot to Windows 10. When I start up Ubuntu I can login, but the entire system freezes a second or two after loading the desktop. I have researched a bit and found this. When I run
sudo apt-get install nvidia-current
I am given a bunch of failed to fetch statements along with
Unable to fetch some archives, try running apt-get update or apt-get --fix-missing
Running
sudo apt-get update
returns a bunch of problem unlinking and failed to fetch statements.
sudo apt-get --fix-missing
returns a list of commands for apt-get.
My graphics card is a nVidia GTX 970, and I believe I need to update the drivers, then fix the boot issues.
