Get back Acer 3820TG eRecovery / D2D / Alt + F10
The first thing I did after unpacking my Acer laptop, was to wipe it and install a clean version of Windows. Little did I think of creating any restore DVDs; when would I ever need those?
Well, now I did. And after lots of searching I almost succumbed to Acer and order their rescue pack. Good thing I didn't though, since I've now found a solution.

Note: You should first verify that you have the restore partition intact before you proceed. Fire up some partition manager and look for a partition that is ~13 GB, and invisible in Windows Explorer.
- First you should make sure that D2D isn't just disabled in the BIOS. If it was, that might've been your problem.
- If it's not: Disable it.
- Boot into Windows, download and install Partedit32.
- Open Partedit32 and you will see a grid of input fields. Every row is a partition, putting the cursor in a text field should reveal the partition's size.
- You must now change file system identifier of the restore partition, so Windows recognize it. Locate the partition that is ~13 GB of size and has 27 in the first field. Change 27 to 07, save and reboot. A new drive should now be present in Windows Explorer.
- Open up Run, enter compmgmt.msc and press OK. Go to Disk Management, right click on the rescue drive and select Mark Partition as Active.
- Reboot. You should now be booted into Acer's restore mode.
