I have a Z585 and created a onekey backup on an external harrdrive. The problem is, I accidentally deleted the onekey recovery partition. How do I get my system back from there?
uff. You might want to obtain a recovery DVD from Lenovo support. Once you successfully factory restored your laptop with it, you can hopefully use OKR once again for backup.
You can try running Easus partition manager and try to recover the deleted parition.
