This tutorial can also help to do it on other computer brands
Disclaimer: First of all you must be aware that some of the operations to come can cause irreversible change on your hard disk, I recommend to you and I will never make it enough make a backup of your system before launching you in any hazardous operation. Any damage and / or modification done on your system will be under your whole responsibility. The following procedures were done on a Acer Aspire 5102wlmi and some also functioned on a Dell Inspiron 9400/1705.
As you know, the Acer computers and those of other manufacturers are now delivered with a system of restoration installed in a hidden partition of your hard disk. This system launches out while pressing keys ALT + F10 simultaneously. And sometimes for various reasons this system ceases functioning.
The first cause often comes owing to the fact that function D2D Recovery is disable in the bios (menu principal).
The solution: enable the function and try to press keys ALT + F10 during the starting of the computer.
The second cause: in this case hidden partition PQSERVICE was erased or damaged, or you replaced the disc and in this case it is not present.
The solution: If you did not previously make a backup of your system by making an image disc. It will not be possible to use the D2D recovery. Your only hope will be to have in your possession Acer Recovery CD / DVD.
And the third causes: the Acer Master Boot Record (MBR) was damaged or replaced by non-Acer MBR. As long as partition PQSERVICE is present or that you can put the hand on the necessary Acer files you can reinstall the MBR of Acer.
The solution:
First method: on a functional Windows system :
1 disable the D2D recovery option of the bios.
2 open a Windows session with an account administrator.
3 Download, unzip and launch partedit32 (registration required for download).
4 Identify the Pqservice partition by its size (at the bottom of the partedit window there is a partition information box) it is a small sized partition approximately 2 to 6 Go.Once made change the type of your partition into 0C and save. Restart and open a session with an administrator account, you should be able to navigate to the PQservice partition. Seek these two files mbrwrdos.exe and rtmbr.bin once localised open a command prompt and launch this command mbrwrdos.exe install rtmbr.bin, this will install the Acer MBR. Close the command prompt window restart again Windows go into the bios and reactivate the D2D recovery. Now ALT + F10 should launch Acer recovery at the starting of the computer.
Second method: On a nonfunctional Windows system .
For that you must use a Linux distribution (for me Mandriva provided all the tools necessary).
1 Boot on the Mandriva install CD / DVD the boot menu will give you the possibility to repair or to restore the Windows boot loader.
2 If that is not enough launch an installation of linux (this will be an occasion to test this terrible OS) and choose LILO as boot loader (a boot menu that allow you to choose between several operating systems) once finished the installation. Restart your computer in the boot loader menu system you will have at least 2 Windows options the first generally point to PQservice choose it and you will boot directly into acer D2D recovery.
The last solution is the simplest one, just note that during the Linux installation you will have to resize your Windows partition to create a place for a new Linux partition it is the most perilous part because irreversible, therefore take your precautions at this time.
