Hi I have a Dell Latitude E6510 laptop. I removed the hard drive and put it into my custom desktop. As soon as I did that I tried to boot it (on the desktop) and it wouldnt boot. So I moved it back to the original laptop. When I try to boot from there, using both Legacy and UEFI, it does not boot. It says it is not bootable. I suspect it is a missing boot flag but I do not know how to change that. I have also booted my laptop with Kali Linux, and in the file explorer all the files on the drive are accessible and working just like a normal drive. I think inserting the drive into my desktop could have changed some boot settings somewhere. Please help!
