it solv my problem....
Excellent AAAAAAA +++++++++++++. Work Perfect
I fixed this issue when I realised I had set a passoword many months ago when I was in Windows 8.1
If you found that your BIOS is locked, use a password you've used for other 'important' things.
I have an Acer Aspire E1-571
I'm having the same problem - however when I press F2 it goes to a blue security box saying: Enter Current Password:
I don't have a password. It was set by the factory, I bought it new. How do I get around this.
The last hard drive is trapped - I can't fix it, even with Microsoft's chat help when they accessed my computer remotely.
I bought a new hard drive, and have the Windows 7 Professional DVD in the drive - but it can't access it under the current Security Settings - only to find it has a Password - thus my visit to this forum today.
Any help you can offer would be gratefully accepted.
What Occurs - Step by Step
1. Reinstalled OS from CD, purchased from ACER
2. Install complete, removed CD, system auto rebooted after the countdown.
3. When system restarted after auto reboot, I get "Windows Boot Manager has been blocked by the current security policy, Click OK
4. Get a message that states
"Default Boot Device Missing of Boot Failed. Insert Recovery Media and Hit any key. Then Select Boot Managere to choose a new Boot Device or to Boot Recovery Media"
5. Attempting the above takes me back to the initial "Windows Boot manager has been blocked..." message.
6. Power on + F2 and I am prompted for an Admin Password which I've never set.
Did you get any anwere to your problem. I have the same problem with my E1-571. Got new recovery CD from ACER but still cant get pass all this messages.
Worked perfectly for me ! Thx
