Hello and thank you for your question. I look forward to assisting you today. Can you tell me please what repair process you tried?
Was this from the repair menu when you first start the computer?
Did you receive an error message or how did the recovery fail?
Did you try a repair or restore?
When you restarted, did you press the F10 key to enter the recovery menu?
Okay, give me a minute please.
What you will need to do is either download the recovery media from Acer or order the CD. Go to this LINK and enter the required information on the page to see if you can download the recovery media.
How are you doing?
Let me know if you need further assistance.
