I just unboxed a Dell Inspiron 7777 on Thursday. I added 8 GB of memory on Friday. I added a 500 GB Crucial SSD on Saturday (today) and cloned the original HD to it using Acronis. It is my intention to use the SSD for the Windows 10 OS and applications and the OEM 1 TB spinner for data. Crucial's only answer for making your system default to their SSD is to physically remove the HDD from the system. That's nuts. Having said that, I cannot for the life of me figure out how to get this system to default to the SSD on boot any other way. I have accessed the bios and their are no drives listed there. Option One is Windows Boot Manager. I feel like an idiot but have already wasted hours trying to figure this out for myself. Please help!
