I got a new Ideapad Y700 and i wanted to cleanly install a win10 pro edition.
Problem is i see a lot of partitions in disk managment and while i am experienced in formatting and reinstalling windows i wanted to ask for some clarifications.
So as you can see in the pic above there are 6 partitions total.
My guesses are:
1) Partition 6 (~20gb) is the OneKey recovery hidden recovery partition, with the factory shipped image (win 8.1).
2) Partition 1 and 5 are win 10 install partitions and will be created automatically in the new install i make
3) Partition 7 idk what it is, prolly some win 10 stuff also but idk
4) D: partition is a lenovo partitions with drivers
5) C: normal OS partition
Are my guesses right?
If i install new windows (delete all partitions and install there the new OS) will there be a problem?
Also, idk a lot about UEFI in win 10 as my old laptop was working with the old system and bios. I guess everything will be sorted out automatically when i fresh install windows?
Is there any reason to create an exact image of this system b4 formating? (warranty issues maybe, i dont have files i m afraid of losing)

Welcome to the Community Forums.
As discussed from this post by neokenchi:
In a UEFI/GPT lenovo machine, this is the usual layout of the partitions:
3.) LRS_ESP 1000MB OEM- The third partition is the EFI System partition which is used for data storage for the Extensible Firmware Interface (EFI) interface
4.) (blank) 128MB MSR - The fourth partition is the Microsoft Reserved Partitionwhich is also used for data storage for the Globally Unique Identifier (GUID).
5.) Windows8_OS 884.2GB Primary - Windows 8 OS
6.) LENOVO 25GB Primary - this contains the Application and Drivers that are preloaded on the OS (the drivers listed on this folder are also available on the lenovo website)
7.) PBR_DRV 20GB OEM - this is your recovery partition - you will need to press theOne Key Recovery button to activate this partition.
Above description details, each partition as most would be similar to your guess.
Deleting the factory image would make the One Key Recovery feature unusable and cannot be restored other than to send it to the factory for reimaging. Related software warranty can be voided with user opted changes but the hardware warranty would still remain active.
Cloning the image on another hard drive has been done by owners before undertaking such step to ensure themselves a fallback just in case things did not work out as they expect. Other simply use their preferred blank hard drive to image a new Windows operating system while the warranty is still available.
Hope this help answer your query.

Thank you for the answers.
One more question remains.
If i want to install fresh win 10 with UEFI i would go on about like this:
1) create a bootable USB flash drive with the install files
2) boot from it
3) delete all partitions and form them into one big partition
4) select that as windows install location
The rest should happen automatically right?
Or do i have to keep/recreate manually the GPT partitions needed for UEFI and just delete lenovo ones?

It would be prudent to make an image of what's originally on the drive. This way you can always go back to the factory preload. One great and free tool to do this is Aomei Backupper: (use another computer to make a UEFI WinPE USB stick and boot from it).
But if you're sure you won't be needing the original preload ever again, then just delete all the partitions in the Windows setup. Once the drive is empty, it will create the new partition layout automatically on its own, you don't have to do that manually.
Still, at the very least it might be a good idea to save the product key from the originally preloaded Windows installation. You can do it with the free NirSoft ProduKey: http://www.nirsoft.net/utils/product_cd_key_viewer.html
