Disclaimer: First of all backup your system before launching into any dangerous operation, some of the operations to come can cause loss of data. Any modification and / or damage done on your laptop will be under your responsibility.
As you know now laptops Acer and those of other manufacturers are now delivered with a recovery system installed in a hidden partition (PQSERVICE for Acer) on your hard drive. Normally this system launches while pressing the ALT + F10 keys, but sometimes that does not work.
What is the problem?
There are many possible causes, but the most common are:
to , the D2D function has been disabled in the BIOS
. Solution: Activate the function by pressing F2 during boot to access the BIOS menu and change the setting, then reboot and press ALT + F10 while booting the laptop
. Note: For all of the following solutions take account of views Max, quote Max now, a contributor to my website "But I want to talk about the way I solved the thing, because it is very rarely mentioned on the web. All methods to fix the problem D2D Alt + F10 are knowledgeable and intelligent, but all of them forget to say something fundamental:
first of all you reconstruct a logical partition D: Acerdata empty FAT32 partition that almost all deletes cause is usually empty. Just do it, everything went well and recovery has worked perfectly. "
Yes, much of the effort to restore fail because of this condition.
B Another common problem Acer Master Boot Record (MBR) is damaged or replaced by another system MBR. You can reinstall the Acer MBR PQSERVICE if the partition is present, or if you can have access to the necessary files.
Solutions:
FIRST
On the values of a partition table functional Windows FAT32 system are OC or OB for FAT32 file system and installed 12 or 1B for hidden partition FAT32, NTFS system for the known values of the partition table are O7 for NTFS installable file system and 27 customized Acer hidden NTFS partition:
1. Go into the BIOS and disable the D2D recovery option.
2. Download partedit32.
3. Identify the PQSERVICE partition for its size (there is an information box at the bottom of Partedit window) it is the small size of the partition of about 4-9 Go.Once made of the type of change partition into 0C (FAT32) or 07 (NTFS) and save. . Reboot and now you should be able to navigate within the PQSERVICE partition
Search for these two files:
mbrwrdos.exe
rtmbr.bin
(the names of these two files can sometimes be different)
When localized open a Windows command rapids as an administrator and type the command "install mbrwrdos.exe rtmbr.bin", to install the Acer MBR . Close the command prompt, re-boot your laptop, reactivate the D2D recovery BIOS. Now ALT + F10 should work and run the Acer eRecovery when the beginning of the laptop.
SECOND
Someone who has tried to follow the first method, but can not find the 2 files found another solution to restore partition.
Use partedit32 to locate the PQSERVICE partition (on Aspire 5920G, its biggest of 9 GB) partition
Change the type to 07 (Installable NTFS), reboot the system.
After reboot, go to the Manage Windows computer and mark the partition as active PQSERVICE then restart again.
Voila !! You can now proceed to the road to recovery
THIRD
On a nonfunctional Windows system.
Download the Ultimate Boot CD (UBCD) run it choose in the menu:
-filesystem Tools
-boot Managers
-For me GAG worked well, but you can choose any of the other boot loader, you will recognize it PQSERVICE type (hidden).
Just install a boot loader and use it to start the PQSERVICE to start the restore process eRecovery.
C The last problem: it was replaced the hard drive (in this case PQSERVICE is no other) or the partition has been erased or damaged
Solution :. I hope you burned the Acer CD / DVD recovery when he had been asked of you at the time of first use, because if you did not previously make a backup of your laptop, making a disk image, you can not use Acer eRecovery.
we give the last words to Max:
"Problem Sorted Alan. And you're right that an external drive to back up data is all important. Yes, I have it and back up my data before starting to ruin ... "
