ok lets start from the beginning.
like everything to do with pc's there is usually always more than 1 way to do the exact same thing, including start the factory restore process.
it sounds like you've created a backup lenovo install stick (your only allowed to make 1 backup copy for legal reasons i believe, but there are ways around that if you needed to make it again for some reason.) that can be used to do a clean install of everything onto a new hard drive if the drive failed, keep it handy and safe.
personally i prefer to make that copy onto dvd's because i think they are a better medium for storing data onto that you may not need for years, than using a flash stick that may lose that data over a shorter time period. (won't go into details of why it loses data even when not used, just to say all storage media does and why the data needs to be refreshed/renewed every so often)
now what do you want to do?
factory restore windows 7? if yes we'll work on doing that first.
remove ubuntu? i've already told you how to do that but can explain again if needed.
install leap in a dual boot system?
choose one to concentrate on and we'll figure it out together.
