My computer was freezing randomly for around 20-30 seconds and it was a faulty SSD. I cloned the contents to a new one. When I disconnected the old one I could boot from the new one and the freezing problems had stopped. But when I try to boot again I get 'Reboot and Select proper device or Insert Boot Media in selected Boot device and press a key'. I reconnected the old SSD and booted, then disconnected it again and booted into bios where I could select the Windows Boot Manager. But it disappeared again the next time I wanted to boot. So I can only boot once after I disconnect the faulty SSD.

I cloned the SSDs with Macrium Reflect. The SSDs are the same size so I just dragged the four partitions that appeared to the new drive. The partitions are:
1 - Recovery NTFS Primary, 2 - NO NAME FAT32 (LBA) Primary, 3 - Unformatted Primary, 4 - (C) NTFS Primary.

So why can't I boot from the new SSD?
