Hey there, Dheemant Palan!
I'd suggest you check if the SSD is in the boot priority in BIOS as well. I'd also advise you to try plugging it in the first available SATA port on the motherboard and see if that will get Windows Installation Setup to recognize it. If it still doesn't help, maybe you should try
resetting BIOS or checking your motherboard/PC manufacturer's website for any BIOS/firmware update available.
Good luck and keep us posted!
