Hi all, 

 

I'm an Acer board newbie, but have years of PC experience :-)   Not that it's helped me on this issue...

 

I managed to overwrite the Acer provided MBR record on partition 1 yesterday during use of a Porteus (portable Linux) USB disk MBR writing tool.  Oops.  System still boots to Windows 7 luckily but I cannot use Alt F10 keystroke to launch the eRecovery software.  I tried using a boot loader to force a boot from the recovery partition, and it attempts to boot Porteus instead of the Acer eRecovery tool. The current partition layout was not changed and is:

 

1 PQSERVICE recovery partition (intact with corrupt MBR)

2 Windows 7 system reserved

3 Windows 7

 

I read articles online about using an EXE file to rewrite the recovery partition boot sector, using MBRWDOS.EXE. I can view the PQSERVICE partition contents if I boot in Windows 7 recovery mode (F8) but I have not found anything useful on the recovery parition like MBRWDOS.EXE or anything else for that matter. 

 

I do have the recovery DVD's I wrote but I'm wondering if I could get my system back to bootable from the recovery partition using Alt F10 via some black magic?

 

Cheers,

 

Paul

    Hello Paul,

     

    Your laptop worked under Windows Vista (PQ SERVICE) before it?

    Hi,

     

    No, my laptop was shipped with Windows 7 Home Premium.  Never had Windows Vista on it.

    Hello Paul,

     

    Have you checked in the bios setup utility if D2D is enabled?

    Yes, D2D is enabled in BIOS.

     

    I'm quite sure it's related to the MBR/boot sector.  If I use a bootloader (such as PLOP) from a Porteus Linux boot, the Acer eRecovery loads.  But otherwise it won't fly.  I definitely corrupted it.

     

    Is there no software/tool to repair it?
