Acer aspire 5515 erecovery manager does not work. i can see three options restore from factory or user disc or exit the only one i can choose is exit

You will loose all data you have put on the computer. When you turn it on right at the beginning there is a black screen and there are a few f key options.
They will flash up with the option when you turned it on, before windows kicks in. Take a look at the user manual to find out for sure.
Press the correct f key before windows starts up, then go through the menus in setup (it will look all crappy and dos like) and find restore factory settings (or something like that) and click yes.
It's a great feature, and will completely kill any virus or **** problems you have had and couldn't get rid of.
Hope this helps. I would appreciate your feed back as I do this for fun not pay.

Acer eRecovery Management
Acer eRecovery Management is a tool to quickly backup and restore the system.
You can create and save a backup of the current system configuration to hard
disk, CD or DVD. You can also backup/restore the factory default image, and
reinstall applications and drivers.

Acer eRecovery Management consists of the following functions:

1 Create backup
2 Burn backup disc
3 Restore and recovery

This chapter will guide you through each process.
Note: This feature is only available on certain models. For systems
that do not have a built-in optical disc burner, plug in an external
optical disc burner before entering Acer eRecovery Management
for optical disc-related tasks.

When using Acer eRecovery Management, you may be prompted to enter the
Empowering Technology password to proceed. The Empowering Technology
password is set using the Empowering Technology toolbar or when first running
Acer eLock Management or Acer eRecovery Management.

Create backup

You can easily create full and fast (incremental) backup images of your system
configuration to hard disk from the main Acer eRecovery Management screen.
Note: Fast (incremental) Backup is only available after a Full
Backup is made.

1 Press <Alt> + <F10> or select Acer eRecovery Management from the
Empowering Technology toolbar to start Acer eRecovery Management.
2 In the Acer eRecovery Management window, select the type of backup you
want to create using Full or Fast.
3 Follow the instructions on screen to complete the process.

Burn backup disc
Using the Burn Disc page of Acer eRecovery Management, you can burn the
factory default image, a user backup image, the current system configuration,
or an application backup image to CD or DVD.
1 Press <Alt> + <F10> or select Acer eRecovery Management from the
Empowering Technology toolbar to start Acer eRecovery Management.
2 Switch to the Burn Disc page by selecting the Burn Disc button.
3 Select the type of backup (factory default, user, current system,
application) you would like to burn to disc. Choosing to burn a user backup
will burn your most recently created backup image to disc.
4 Follow the instructions on screen to complete the process.
Note: Create a factory default image when you want to burn a
bootable disc that contains your computer's entire operating
system as it was delivered to you from the factory. If you wish to
have a disc that will allow you to browse the contents and install
selected drivers and applications, create an application backup
image instead — this disc will not be bootable.

Restore and recovery

The restore and recovery features allow you to restore or recover the system
from a factory default image, from a user created image, or from previously
created CD and DVD backups. You can also reinstall applications and drivers for
your Acer system.
1 Press <Alt> + <F10> or select Acer eRecovery Management from the
Empowering Technology toolbar to start Acer eRecovery Management.
2 Switch to the restore and recovery page by selecting the Restore button.

previously created CD/DVD or reinstall applications and drivers.
4 Follow the instructions on screen to complete the process.

You can launch Acer eRecovery Management in a number of ways:
• By pressing the hotkey <Alt> + <F10> during the boot-up process, or at any
time when you are running Microsoft® Windows®.
This will open the Acer eRecovery Management main page.
Password
Acer eRecovery Management requires a password to activate. The default
password is six zeros (0s).
Note: If an incorrect password is entered three times, Acer
eRecovery Management closes and returns to Windows®
automatically.
System recovery
Step 1: Click on “Recovery actions”.
Step 2: You are presented with a list of available options
CHOOSE-->Recover system from CD/DVD backup
If you choose to restore from an image on an optical disk, the BIOS will be
changed to boot from the optical drive. If no backup disk is found, you are
prompted to insert the disk.
Reinstall
IF THOSE DISKS DONT WORK , YOU CAN ALWAYS RESTORE TO FACTORY SPEC FROM THE HIDDEN PARTITION ON YOUR HARDDRIVE.
Hope this helps you out .. Regards
