Mbrwrdos.exe for acer travelmate

Hi, thx for your help on my problem. However it is no good for me since I can't even get to the point where I can tap F8. I need to rewrite the MBR from DOS and the only file I have is to rewrite the MBR from Windows, which I can't boot.

SOURCE: I really NEED mbrwrdos.exe for my Acer!

Have you tried booting in safe mode? Repeatedly tap F8 while booting and you will beprompted asking if you want to enter safe mode then allow it to load;

Furthermore you could remove the Hard Drive and put it into another computer providing it is a matching connection with the other machine e.g. Sata - In the event it is a Hard Drive failure which by the description you have given is a distinct possibility you can send it to the manufacturer for data recovery.

I hope this was of some help ;)

The error message says fatal system error.


Hi. The STOP 0xC000021A error occurs when either Winlogon.exe or Csrss.exe fails. When the Windows NT kernel detects that either of these processes has stopped, it stops the system and raises the STOP 0xC000021A error. This error may have several causes. Among them are the following:
  • Mismatched system files have been installed.
  • A Service Pack installation has failed.
  • A backup program that is used to restore a hard disk did not correctly restore files that may have been in use.
  • An incompatible third-party program has been installed.
Booting the computer to its Last known good configuration will resolved the issue. Please see procedure below:

Turn of the computer
Keep on tapping F8 key the moment you press the power button
You should be getting a advanced boot screen
Select Last known good configuration from the selections then hit enter
Computer should be booting up by now to windows

All the best!

D2d recovery


Hello Sir / Madam,

Many Acer systems come with the ability to press ALT+F10 to kick off the Acer Recovery applications from a special hidden recovery partition. Sometimes this won’t work and there can be a number of reasons.
1. D2D Recovery is “Disabled” in the BIOS (Main menu).
FIX: Enabled it and try pressing ALT+F10 again as the computer boots.
2. The Acer hidden recovery partition (PQSERVICE) has been removed or damaged. If the disk drive is a replacement drive then you won’t have this partition.
FIX: Unless you have previously imaged the PQSERVICE partition it will not be possible to use D2D recovery. You will need to restore from the Acer Recovery CD/DVD.
3. You have converted the FAT32 partition on the hard drives into NTFS. Acer D2D recovery won’t be available if you perform this conversion. Ironic that NTFS is a more desirable disk format to use but Acer won’t support this in their systems!
FIX: Restore your system from the recovery CD/DVD media.
4. The special Acer Master Boot Record (MBR) has become corrupt or has been overwritten with an non Acer MBR. As long as the PQSERVICE partition is there or you can get your hands on a couple of Acer service files for your model, then you can remake the special Acer MBR. Let’s cover how this is done.
  1. Disable D2D recovery in the BIOS. Can be found in the “Main” menu section. Save the BIOS settings and exit.
  2. Log into Windows with an “administrator” level account.
  3. Download ParTEDIT32.ZIP (registration required for download).
  4. Extract PTEDIT32.EXE from the zip archive and run it.
  5. Identify the PQSERVICE partition by its type or size. It is likely to be 12 or another custom value and is likely to be reasonably small in comparison to the other normal partitions - see the example below from a working factory default Acer. Click the Link below see the image full size. http://www.roundtripsolutions.com/blog/wp-content/uploads/
  6. 2007/10/AcerDiskRecoveryBroken_F031/hidden.jpg
    Change the type to “07′ (Installable File System NTFS, HPFS) and “Save Changes”.
  7. Reboot the computer and login with an “administrator” level account.
  8. You should then be able to open up a command prompt and navigate to the PQSERVICE drive.
  9. Enter the following command at the command prompt:
    mbrwrdos.exe install rtmbr.bin
    - You may have to search for these files and change into the relevant directory.
    Note: This step writes the Acer MBR, with mbrwrdos.exe and rtmbr.bin being the special service files.
  10. Close the command prompt window and reboot.
  11. Go into the BIOS again and enable D2D Recovery. Save the BIOS settings and exit.
  12. ALT+F10 should now start Acer Recovery as the computer starts.
  13. The Acer MBR ensures the PQSERVICE partition is hidden therefore there is no need to reset the partition type back to 07 - well there shouldn’t be if all has gone well. If you need to manually reset it then run PTEDIT32.EXE again, set the partition to 12, or whatever the original value was, and save the changes to complete the process. Reboot and it should now be hidden.
If Windows is unbootable, due to whatever issue, you can always use the Ultimate Boot CD for Windows (UBCD4Win) along with a copy of PTEDIT32.EXE to achieve the same results. Likewise, use UBCD4Win along with PTEDIT32.EXE if the PQSERVICE partition is being changed back to a hidden one by the existing MBR. We’ll leave that as an exercise for those who need to do it! It has been pointed out in the comments that UBCD4Win already has an application that will do partition maintenance, so checkout TestDisc if you go down that road.
If this is a new drive or someone has completely wiped the drive, including the hidden partitions, it may be necessary to use partitioning software to recreate the partitions that the Acer Recovery system is expecting! You’ll also need to restore an image of the recovery partition from a previously made backup, so it is worth making that backup image straight away while the laptop is still new and shiny, and certainly well in advance of any problem.
A final word or two of caution: take great caution when playing around with partitions on an Acer system… you have been warned… and remember to make the backup media disks as soon as you fire the computer up for the first time!


Thanks
Good Luck
