"BootMGR is Missing" after restore Factory Settings attempt

Try to install from the recovery partition like this:

Restart your PC and press ALT+F10 when you get the first splash screen - or check on that screen whether they want you to press something else. That gets you to the installation wizard that will guide you.

You run it the same way you ran it when it go botched.

In your 1st post you said you ran factory recovery, didn`t you ?

As WHS says, you look for the appropriate key to start the recovery process during 1st boot. It will tell you at the bottom of the screen.

When you see the ACER screen press Alt then F10 with Alt still depressed (ALT+F10) then release and fairly rapidly repeat the process. I have found on ACER you may need to try a few times.
The BIOS POST runs its course before the ALT F10 interrupt occurs.

Excellent, if you are done, please mark the thread solved.

Ok! ALT+F10 was the key. The Acer splash screen doesn't list it, it just says press F2 to enter Setup. I got it to return to factory settings this time.

The way I ran factory recovery when it got botched was through control panel.

Thanks everyone! I thought all was lost.

I am glad you got it sorted and that we could help.
