From this, you’d better make a custom recovery partition after upgrading.
In general, Lenovo OneKey Recovery partition will only be there on the factory installed HDD and it won’t work on new hard drive even if you don’t make any changes. So, my question is: how do I make the OEM and recovery partitions, just after installing Windows 7 on a new HDD to facilitate the ‘OneKey Recovery’.
The only thing bothering me is the ‘OneKey Recovery’. 'I own a Lenovo IdeaPad Z570, and want to upgrade to a larger HDD(from 600GB to 1TB).
