C drive size?

I want to restore my Acer Aspire One 531h back to factory default. But I've come across a problem. When I try to use 'Acer eRecovery Management' and specifically the 'Completely Restore System to Factory Defaults' feature it tells me that 'Hard drive configuration is not set to the factory default. Restore aborted.'
I believe this is because I have partitioned my hard drive on various occasions and now the C drive is not the original size. What I want to find out is the exact size of the C drive on a factory default Acer Aspire One 531h (or similar) so that I can resize the partitions and therefore restore the system to factory default settings. The best thing for me to see would be a screenshot of Disk Management, so that I can see the exact size of all the partitions. Like this -

A big thanks goes to anyone who can resolve this or even just contributes.

Don't know how helpful this is, but you won't be able to run the factory restore with Windows 7 installed. From factory your hard drive will have a 12gb partition (recovery partition) and the rest of the drive is partitioned off for Windows.

But when you install Windows 7, (if you have removed the old XP partition) Windows 7 setup will create the 100Mb partition you see in your Drive Management screen. As far as I'm aware, this contains the boot loader among other things. If you remove this partition, Win7 will not be able to boot.

What I'd suggest, if you want to do a factory restore, is boot the Windows installation again and modify the partitions. Basically remove the 100Mb partition AND the Windows partition, leaving your 12Gb recovery partition untouched. Then, create one large partition out of the remaining available space. Your factory recovery should then go fine as the partitions should be the same as they originally were from factory.
