Thank you for your time. I just installed a second SSD (Samsung 860 EVO) internally on my TC-885-UA92. It shows up in BIOS. However, on the Boot Menu neither of the SSD's (WD NVMe that it came with nor the Samsung SATA) are displayed to choose from. Only Window Boot Manager is displayed, then Optical Drive, etc.
How do I change between SSD's for testing and dual booting?
