I've recently purchased a Lenovo B570 laptop and decided that I'd like to repartition it.
So I created a Windows disk image using the built in feature and booted the device using an Ubuntu live USB disk.
But after I checked the current partition scheme I noticed there are 2 hidden partitions. One is 200 MB and contains the boot data (e.g.
bootmgr, etc.) the other is 15 GB and after mounting it there was again the boot data and some other data such as
OneKeyRecovery backup files, a folder named
Factory_Process and etc.
Now I'm having second thoughts. What should I do here? I'd very much like to delete everything and start fresh. But would I lose some critical material which is needed for the proper functioning of the device?
Any help and insight is much appreciated.
