Toshiba Satellite c55 D will not boot up, boot config data missing, HDD supposedly not recognized

Yesterday, I was using my laptop, when my brother jumped on the bed, and the laptop turned off abruptly. After trying to turn it on, it said: "Repairing disk Errors". I don't know what compelled me to foolishly turn of the laptop, but after booting it, it said: Error 0xc0000185. The boot configuration data for your pc is missing or contains errors.this is what it looked like

I got a little spooked, so I made Windows 10 installation media using MS' tool, and tried to boot from it. There were two options, repair, and install. I chose repair, and it brought me to the troubleshooting screen, where I had to fix the boot record using command prompt. That didn't work,* so I tried to install windows, but it showed that my HDD has 0 GB of storage. After rebooting, and letting it run for 13 hours, I decided to turn it off and go to bios. From there, it says that there is no HDD/SSD.

What should I do guys? I don't mind using Linux, but how do I break this cycle?
