Factory restore Lenovo
boot into windows PE
partition magic
find the Lenovo_part partition and change type from 12(Compaq) to 7(ntfs)
add a drive letter and mount
copy the contents somewhere
put the partition back to 7
clear out your windows partition you want to replace (in my case it was e:), so delete all content
navigate to your copy of the Lenovo_part\okrbackup\factory
extract all contents of os.okr using 7zip into cleared out windows dir
then reboot
fingers crossed
Hope this was help full
