Create a System Rescue USB drive (Note: An alternative to the spyware-laden Daemon-tools for mounting the ISO file as a virtual CD-ROM is Virtual CloneDrive). If you have trouble with the System Rescue CD, you can try some other distros.
Reboot the netbook and go into the Acer BIOS settings. Change the boot settings to check USB first. Plug in your System Rescue stick, and restart the netbook.
Run “wizard”, and launch gtparted (icon towards the lower-left of the screen).
Delete partition 2, create a new one, then reformat it as NTFS
Mark partition 1 as bootable (right-click, edit flags). Remove USB drive.
Reboot into the Acer System Restore software. Choose to restore the system.
Plug the System Rescue USB drive back into the Acer netbook.
Reboot into the System Rescue CD/USB, go back into gparted, and flag the restored partition 2 as bootable.
