I ran some code with little too many threads and my computer crashed. When I rebooted, I got the "Please select boot device" menu. I tried switching different booting options but nothing worked. I am now booted from USB. The disks application claims my disks are fine. I have some important work files I want to recover. How can I fix the boot thing since the disks are "fine" and how can I recover my files?

After some sniffing around I found my work files. The issue now is how to fix this.

I ran this answer. It ran successfully but nothing changed

Results from gparted :

    Personally, I don't understand your question or your answer. It's not clear from your description what you did that caused the problem, and your answer doesn't provide any details/instructions that someone could actually follow if they did need to fix that problem. It's always better to provide exact instructions instead of narrative descriptions that are ambiguous.

I fixed it. It seems likes after the crash the boot option for my SSD was void. I reset it to Ubuntu and it works now. I guess 100 threads were too many.
