restore original mbr in acer


I have an Acer 4315 that I will soon be selling. I kept the recovery partition on it and Vista, but was using Gentoo exclusively.

Now, I want to restore it to factory defaults (the Alt+F10 thing). I have no recovery CDs (thanks to Acer).

Everytime I booted into Vista and used Acer's eRecovery program to reset to factory settings, it would shutdown and restart. I think it was trying to boot to the recovery partition (label = PQSERVICE)(/dev/sda1), but instead, grub kept appearing and not using the default MBR.

This whole time Alt-F10 did not work.

I then shutdown windows before it could boot, which allowed me to access the Acer tool to check windows, etc - I entered their command prompt and typed:

MBRwrWin install RTMBR.bin

I had found that in many forums for reinstalling the original MBR.

Now, when I restart, I see the BIOS splash screen, it gets to the bootmanager stage and reboots. I was not seeing Grub or the Windows Bootmanager - it just continually cycled.

I then booted up SystemRescueCD and reinstalled Grub where it had been (hd0,6) so now I can boot into Gentoo (at least), but I still cannot boot into Windows (with the same menu.lst entry).

QTparted states the recovery partition is Fat32 (which agrees with what others have said), but in cfdisk, it is listed as unknown. I have tried making it bootable, but that did not work. It is not hidden. It is /dev/sda1 - so first partition, and as I understand it, the grub entry should be (hd0,0).

Any ideas?

If I can just replace back to the original MBR then the Alt-F10 (restore to factory defaults - D2D) should work.

may be if you can enter the windows boot partition to the grub it might . Or can you try with any of other Windows Bootable CD and boot from it. If you are sucessfull in that you can rewrite the MBR .

Generally all the bootable windows cd repairs the MBR by itself ,or you can try with fixboot command in XP or if it is Vista i am not sure .

Once if you have windows booted , there will be an option to create recovery disk from the partition ( you have to search in Acer settings or something )and that disc's will be specifically to your notebook.

You should have created the recovery disc when you have bought it ( leave it thats old story ).

Once you create the recovery disc, you have to boot from the recovery disc and restore original factory settings to your entire notebook , it repartitions the harddisk and also creats the recovery partition and then you can sell it.

If i am too abstract let me know on which part you want more description.

Good luck .

Thanks

You are right in that if I can get into Windows, esp if I had a bootable cd, I could likely fix it - but I have no CDs and, no I did not create any.

This is what was not working for me (it kept rebooting and starting grub/linux, not the recovery partition).

- Yes, but a large hassle as it would have been I think 9 CDs!

Thanks for your help though and your quick reply - I submitted an e-mail support question to Acer and will post their reply if helpful.

Are you sure , when you are trying to create a recovery disc the machine is getting reboot ?????

Do you think 9 CD's not worth for what you are suffering right now ?

Try any of other bootable windows CD , if you can get one just to boot.

I am not sure how ACER will help you in this. They ( most notebook provider ) don't prefer if you are installing other OS other than the original one to you notebook .
