There are many reasons to clean install windows especially for Lenovo y510p users. Straight to the topic, to perform a clean install you need a windows 8.1 Single Language iso file which can be downloaded from torrent sites. In my opinion it's not illegal to download the iso file since Windows includes in your laptop price. I'm not posting the torrent link here but you can check this hash in google to find the iso file " DFDE67503F4E625EF6E7FED43DA8A5766F3D2B3E ". I recommend downloading it from " piratebay " but beware of torrent sites. Once you download the iso, you have two options:
1 - Burn it to a DVD & install (or)
2 - Burn it to a USB drive & install
Download Windows 7 USB/DVD Download tool & install it.
Download from Softpedia
Select Browse & select the iso file where its located
Click next
If you want to burn it to a DVD, select DVD or if you want to burn it to an USB drive select USB
Select begin copying & wait untill the process finishes.
If you are planning to install through USB , shutdown the laptop & press the novo button
Select BIOS setup, go the BOOT tab & Enable USB Boot.
Reboot the laptop, press f12 once you see the Lenovo logo to enter into the boot menu & select the USB device .
That's it now you can install windows with this product key " Y9NXP-XT8MV-PT9TG-97CT3-9D6TC "
Once the installation process finishes, Run the command prompt as an administrator and type
slmgr /upk to remove the product key & type SLMGR /IPK XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
where XXXXX-XXXXX-XXXXX-XXXXX-XXXXX is your product key

Run it. Click on the ACPI Table button at the top. After that click on the MSDM tab. Your BIOS's product key is at the bottom.
that's it.
