If you own a Lenovo laptop that came with windows 8 and you happend to change the partition size so you could dual-boot windows/linux or accidentally wiped the drive ; by now you must have realized that your one-key-recovery is no longer working.
OKR8 is Lenovo's propritary install image that autocreates the lenovo paritions. You will need this in order to make one-key-recovery work again.
Hope it helps
