I have a Dell Inspiron 15 7559. Last night, I added a V-NAND SSD 850 EVO with a 500GB capacity, where I planned to clone my current 1TB (with only 264GB used) HDD.

I plugged it, and booted normally. When trying to clone it with Samsung's cloning software, the app became unresponsive and then exited by itself without issuing an error. As I wasn't sure if it had been cloned, I tried to reboot.

Since the, I can't boot with my SSD plugged in, even if I try to boot from the HDD. I tried adding new boot options, but they won't work.

The HDD alone boots just fine. As soon as I try to boot with the SSD connected, it will start the Auto repair.

BIOS sees both disks, and if I go to the command prompt and issue the diskpart command, I see both disks, with the SSD being empty.

How can I do to boot with both drives connected, so I can clone it again?

Thanks in advance :)

Well, after a while, I noticed that the SSD was not "GPT". I entered into command prompt and with diskpart I converted it into GPT, and also created EFI and MSR partitions (not sure if that was necessary, but I did it anyways).

After that, I could boot from my HDD normally and give the cloning a new try
