Disk Migration

2021-06-10, 5:36 AM

I recently lost my E480 and bought a P51 to replace it. I was hopping I could boot on my previous computer's HardDrive but Windows Boot Manager just looped. 

This previous HD was an M2 type and run windows 10.

Is there a way to recover my previous session or do I have to use my old HD as a secondary one?

Hi sam4747,



Welcome to the Community Forums.



The Thinkpad P51 supports the following:


  • Up to 3 drives (two M.2 SSD and one HDD), supports single sided M.2 2280 drives only


  1. Some: HDD / SATA 6.0Gb/s, 2.5" wide, 7mm high, Active Protection System
  2. Some: M.2 SSD / PCIe NVMe, PCIe 3.0 x 4, 32Gb/s


The P51 supports M.2 SSD's according to the specifications, so as long as you boot on the main drive for the P51, your device should be able to boot with the E480 as a secondary.


Please try to perform the settings below in an attempt to remedy the issue.


BIOS Load Default Settings.
- Press the power button to completely shut down the unit.
- Press the F1 or F2 (FN+F1 or F2) repeatedly on startup to enter BIOS.
- Navigate to the "Restart" tab
- Press "Load Default Settings"

- Navigate to the "Boot" tab and make sure the original HDD/SSD for the P51 is at the top of the boot order.
- Save & Exit changes or F10.


Boot up as usual for the original drive and proceed with recovering your files.


If you still face issues after this, then there could be a hardware fault with the SSD from the E480 that is preventing you from booting.


Hope this helps

From looking at the specs of the T480 and P51, it appears they use different generations of CPU hardware.   Since Windows is not a portable operating system, it is unlikely the older generation P51 will boot from the drive from the newer generation T480.

The best way to get things working as smoothly as possible would be to perform a clean installation of Windows 10 to the P51 using the downloadable factory recovery media, get it all updated and configured as you prefer, then connected the old drive using an external USB adapter and copy the data over to the new drive.
