Alright so I bought myself the Samsung 860 EVO M.2 ssd drive and I cloned my old hdd into it. I had to initialize it and make a partition before everything. The task manager and manual boot from F12 recognize the disk , as well as it is recognized by the bios . The problem is,  after freaking out a lot I can t make it appear in the boot priority list. It just doesn t appear there and I cant make the system run the Os from the SSD. I also disconnected the old hdd and the system eventually used the ssd automatically but as I could observe , it took a while because it seems it looked for it.

The latest BIOS for the alienware 17 r2 is the A10. The thing is , there isn t any hdd or disk list shown there either.

I don t know what to do , Im quite handy with computers but this is too much. Im either going to quit and boot it every time manually or trying to look for more answers.
