I have a Gigabyte p35x laptop it came with 1 SSD, 1HDD, and i can replace the optical drive with another HDD. It has Windows 10 installed on the SSD. So i removed my HDD(having windows 7) from a previous laptop, and replaced the optical drive with that. Now how can i boot on the second HDD(windows7) ? when i try from the bios to choose the booting device, i have only one option which is the SSD (NVMe)
Any idea how i can set dual boot ? so that i can choose between Windows 10 or 7 when it boots ?
