Question HDD doesn't get detected in BIOS but can access it if I boot from SSD

[Socratides]

Hello everyone.

So, I bought a new PC yesterday which came with an SSD (128 gb) and a HDD (1 tb). I have an old HDD (500 gb) so I went ahead and installed it. Booted up PC and pressed F12 to access BIOS menu. In the boot sequence menu, only the SSD is showing up. Booted SSD and went to check if HDD is showing up as a drive. It was there as the E:\ drive. I can access its files easily but I wanted to try to boot it since I'll be installing ubuntu on it. Any response is appreciated.

Thank you.
