Note: I am still a novice with computers.
I have an Acer Aspire E5, with Windows 10.
I just installed Ubuntu from a USB (somewhat) successfully. Had a hell of a time, I think it is because I did not properly boot my computer before installing? It kept taking me back to the black screen upon restart. Nonetheless, I do now have Ubuntu running properly.. I am able to use it with all of its full features, my data and settings continue to be saved, all of that good stuff.
Yet, every time I restart my machine, it takes me back to the original black screen asking me if I want to try Ubuntu, Install Ubuntu, etc. or says "cannot find bootable device" if my thumbdrive isn't in.
When I go back to the boot menu from this black screen, I can select my own hard drive rather than USB.. from which it will take me straight to my log in screen for Ubuntu, when I log in all of my files and settings still in tact as it should be.
Why does the black screen come up still when I restart, if the system (in some form) is still running properly?
I really appreciate any help here. What is the problem, and how can I fix it? Thanks.
