Factory reset my Lenovo Legion Y520, lost recovery partition

Hello community,

I recently factory reset my Lenovo Legion Y520 - 15IKBN and I lost my recovery drive that usually sits in My Computer. Before I used to see Local Disk (C: ) and LENOVO (D: ) but now after the factory reset I only see Local Disk (C: ). What does this mean? Does that mean I lost my recovery drive? How do I get back LENOVO (D: )? Thank you.

Re: Factory reset my Lenovo Legion Y520, lost recovery partition

Hi Green_phantom


Welcome to the Community Forums.


I believe the D drive is not necessarily a recovery partition on your model as discussed here on this post.

From the example shown on the new Y520 with 1 TB hard drive, C -117 GB and D 931 GB.


About partitioning

The larger drive known as the D drive which is ready for storing your personal data files such as videos, music, pictures etc. Both the C and D drives are visible in Windows but the D drive is MUCH larger to hold all your personal data. 


This model may not have the traditional OKR software that reset PC using One Key Recovery from initial backup, but instead "Reset this PC" is a built-in recovery tool that enables users to restore their operating system to its original state. This preserves their data and important customizations, without the need to back up their data in advance (reference to user manual page 17)


"What does this mean?"

After reset, try checking on the total space of the actual drive as this should maximize the C drive as single partition.

You can use disk management tool for verification (Win+R  and type Diskmgmt.msc).


If you would like to recreate a D drive to separate as a repository for your data files, you can go to disk management to shrink current drive C: then create the unallocated space for a new D partition.


Before doing it, it would be better to create your recovery drive first as discussed here (start with the video clip for interactive details).


Hope this helps answer your query.
