The Acer D2D Erecovery 101


Disclaimer: First, back up your system before you embark on a dangerous operation, some of the upcoming operations may result in data loss. Any modification and / or damage to your laptop will be your responsibility.

As you now know, Acer laptops and those of other manufacturers are now shipped with a recovery system installed in a hidden partition (PQservice for Acer) on your computer. Hard disk. Normally, this system starts by pressing the ALT + F10 keys simultaneously, but sometimes it does not work.

What is the problem?

There are many possible causes, but the most common are:

A The D2D function has been disabled in the bios.

Solution: ] Activate the function by pressing F2 during startup to access the bios menu and change the setting, then restart and press the ALT + F10 keys when starting the system. laptop.

Note: For all that follow The solutions take into account the Max tips, I quote Max now, a contributor on my site "But I want to mention the way I've settled the thing because it is very rarely mentioned on the web. All the methods to repair the Alt + F10 D2D are well informed and intelligent, but all forget to say something fundamental:

First of all you have to rebuild with a soft partition the empty partition D: Acerdata FAT32 that almost everyone removes cause is usually empty. Just doing it, everything went well and the recovery worked perfectly.

Yes, many restore attempts fail because of this condition.

B Another common problem: the Master Boot Boot Record) is damaged or replaced by the MBR of another system. You can reinstall the Acer MBR if the PQservice partition is present or if you can access the necessary files.



On a Functional Windows FAT32 System the partition table values ​​are OC or OB for installable FAT32 system files and 12 or 1B for the hidden FAT32 partition, for an NTFS system the known values ​​of the partition table are O7 for the installable NTFS file system and 27 for the NTFS partition

1. Go to the BIOS and disable the D2D recovery option.

2. Download partedit32.

3. Identify the PQservice partition by its size (there is an information box at the bottom of the partedit window) that is the small partition size of 4 to 9 GB. Once made change the type of your partition in 0C (FAT32) or 07 (NTFS) and save. Restart and now you should be able to navigate through the PQservice partition.

Look for these two files:



(The name of these two files may sometimes be different)

When located, open a prompt window of command as an administrator and enter this command "mbrwrdos.exe install rtmbr.bin", to install the MBR of Acer. Close the command prompt, reboot your laptop again, re-enable D2D recovery in the BIOS. Now ALT + F10 should work and launch the Acer Erecovery when the laptop will start


Someone who has tried to follow the first method but n & nbsp; Failed to find the 2 files found another solution restore the partition.

Use partedit32 to locate the pqservice partition (on aspire 5920g, its largest 9gb partition)

Change the partition type to 07 (NTFS installable), reboot.

After rebooting, go to the Windows computer management and mark the PQservice partition as active then reboot again.

Here it is !! You can now proceed to recovery


On a non-functional Windows system.

Download CD Ultimate Boot (UBCD) run it choose in the menu:

– File System Tools

-Boot Managers

-For me GAG worked fine but you can choose any other bootloader, you will recognize the PQservice by its type (hidden).

Simply install a bootloader and use it to start the Erecovery restore process in the PQservice

C Last problem: You have replaced your hard drive (in this case, PQservice n & # 39; is no longer present) or your partition has been erased or damaged.

Solution: I hope you have burned the Acer Restore CD / DVD when asked when you first use it, because if you do not have the Have not Previously make a backup of your laptop by making a disk image, it will not be possible to use the Acer Erecovery.

Let us give the last words to Max:

"Sorted problem Alan. And you're right to say that an external drive for data backup is important. Yes I have it and saved my data before starting to screw up … "
