Laptop doesn't recognized freshly cloned SSD

Hi,

I’m having a similar problem.

Upgrading laptop 500gb HDD to sandisk Ultra II 960gb SSD.

Clone went ok, no issues. Even appeared in Explorer after it finished as extra drives (it was connected via USB to do the clone) Shutdown and replaced the HDD with SSD. The laptop bios recognises the drive but not on the boot priority screen.

Needless to say it doesn’t boot either. Just tells me “no bootable device”

Went out on a limb and just decided to do a clean windows install and still the device cannot be selected as a boot drive.

Still appears in the bios though.

Any ideas? It almost as though the laptop needs very specific drivers to make the SSD work.

Thanks

Dave
