🙁 Didi the same thing to my Acer sadly, did a lot of searching on the web, but then I can across a site talking about a ISO Image that you can download from Acer. This will repartition your drive like when the computer was purchased, including the PQService partition, but if you want to rebuild PQService partition, you will need your Recovery disc (You would have one if you burned it before formatting PQService) if you don't have one though, do a Google search 'Acer RCD' and buy it from Acer (It only costs $19.95 for mine). To get the ISO image to repartition the drive, visit AcerPanAm.com, go to Drivers and Downloads (don't need to select a country), click the link at the top of the Drivers and Downloads Page 'Link to the Old Page', this will open a new window. Enter in your Computer info and at the bottom of the Drivers and Downloads page, you should see "Post Acer Disk Formatter CD ISO Image", download it. This is only 200MB, but remember, you will need your recovery disc for the PQService, because the PQService is like 5GB, and you can't get 5GB out of 200MB. Now i've never tried this, because i've just ordered my Recovery disc from Acer RCD, but I will try it asap, i can't wait, but from what I've read, this should save you that £70 (Whatever that is in $, not sure)
This should fix...
PQService partition
Not D2D system error when installing eRecovery
Format computer with Alt+F10
The "Repair my Computer" option when Pressing F8 while booting up computer
NOTE: This will require you to FORMAT YOUR WHOLE HDD. So backup everything on thumb drive or CD/DVD, don't even backup on your D: drive.
