System doesn't detect /dev/sda1 partition, even though /dev/sda5 is detected
by RCRalph from LinuxQuestions.org on (#5PQFN)
Hello everyone,
I've been using Pop!_OS 21.04 only for around three days, this is my first distro and I'm having trouble with accessing my sda1 partition on my drive.
When I run the sudo fdisk -l command, it outputs the following:

I've already installed Pop!_OS on the sda1 partition and I've been using it for a bit of time, until I shut down my computer.
When I turned it back on again, I couldn't get my system to boot.
I only saw a black screen.
When I pressed the escape key, nothing showed up, except:
Code:mdadm no arrays found in config file or automaticallyWhen I go into file browser using the system on my pendrive, it detects the sda5 partition, but it doesn't detect sda1.
What should I do to be able to boot from my sda1 partition again?
Thanks for your attention :)
