Unfortunately the BIOS still doesn't recognize the RaspberryPi... I tried it with other hardware (a USB Armory) and it is recognized without any problems. I was also able to rule out the timing problem because the RaspberryPi is definitely on when the laptop starts.
On or booted? There is a difference. The gadgets won't be present for the laptop to detect until after the Pi has completed its boot.
However, I noticed that Windows only recognizes the drive from the RaspberryPi when it is connected to the usb-c port of the RaspberryPi... it does not recognize any device via the USB 3.0 ports...
Correct. The USB A ports on the 5B cannot act as USB devices (whether USB 2 or USB 3). Only A, A+, and 3A+ can do USB device mode on their USB A ports.
Power might also be an issue. If the Pi is solely powered by the laptop enough current may not be available. USB2 devices shouldn't draw more than 500mA (100mA before enumeration), USB3 devices without PD should draw no more than 900mA. 500mA is border line for a 4B let a lone a Pi5.
I use these to independently power a 4B/400/Pi5 without backpowering thr USB host.
If you share your exact configuration (config.txt, cmdline.txt, any other files you have modified) we may be able to help further.
