I was given a Dell Inspiron 24 3455 all in one computer that was having issues. I factory reset it and it worked okay but disk was always at 100% so I decided to get a Samsung EVO 860 SSD. I went through the media creation tool and Rufus app deleted all partitions and allowed the OS to create new ones. After the install it did not boot. For no apparent reason I decided to try the SSD on my laptop a dell Inpiron 5521 and it booted up no problem. So I know the install was done correct but why would it work on one computer and not the other, especially the computer I used when installing the OS? Any help would be greatly appreciated.
