Hardware Problem. "Missing Operating System"

[Boost]

I've found an article to help you out. Let me know if you need any sections of it explained.

I've read that article. Tried everything. I tried booting a Hiren'sBoot on every disk separately and it worked.. Both disks won't work together at the same time and it has something related to my PSU or my Motherboard.. Tbh, I've been seeing some random behavior from my PC often which made me reach a conclusion of the PSU Theory so, umm... I'll update this once I get a new PSU and check if it's a PSU error or not, if not I'll just mail my PC to my father and let him fix it instead cuz I'm tired of thinking tbh

So, yeah... PSU problems are extremely rare. Every year I do an upgrade to 1 hardware to my computer, luckily last year I got 3 items upgraded, which are my processor, my motherboard, and my power supply. the power supply just came along idk y or how but I didn't really care and I got everything assembled giving no attention to the quality of the PSU nor the motherboard. By time I realized that my motherboard is really unique as well as my processor but they really do not matter atm, what matters is my PSU since it's been low voltage to my hard drives, supposedly, so I'm going to replace that PSU with my previous one (( Searching in my room for something is like a treasure )) Hopefully, this article helps someday. I'mma update this post and tell the results once I do it.
((FYI: The pic up I uploaded is for someone else who had nearly the same problem, not me. LOL))

Think about it like this: whatever you give the first hard drive, you'll need double that to fuel the second hard drive. If you don't, your motherboard will hopelessly try to split the power between the two and neither of them would work. I initially thought this was the PSU theory you had in mind. Best of luck fixing it.

Someone lock this and archive it... It's a hard disk error, bad sectors in my second hard disk it appeared to be... Not a PSU error.. FML.
ROFL wasted my freaking time on installing another PSU realizing eventually it's a bad sector caused by my files on the second disk... Meh.. I'm so pissed rn..
