I have decided in the end to use the recovery partition.
It's an Acer Aspire so I Rebooted and used Alt+F10 at the first screen (recover partition is enabled in BIOS by the way) but it wouldn't load the recovery tool.
I then found out that you can use the recovery partition by going to windows>All Programs>Acer>Empowering technology>Acer ereovery tool
BUT... the erecovery tool is not there.
I have confirmed that the recovery partition exists on the laptop by looking at disk management (there is a 10gb partition put there by ACER).
So. I downloaded the erecovery tool directly from ACER (the correct one for the model number) and tried to install...
The install hangs at the part where it says "Acer erecovery management setup is preparing install shield wizard"
It just stops there and doesn't install, the only way I can get out is Task Manager...
