Go to the page I gave you ( http://support.acer-euro.com/empowering_technology/utility2.html ) download this and install it first then the erecovery and it should let you make a recovery disk with all the drivers and it will be stock just like when you bought it.
First: Acer Empowering Technology Framework Version 2.03.2015 (install this utility first)
Second:Acer eRecovery Management Version 2.0.2021
Edit: If the recovery partition is still there this should work!!!!
