I just bought a Acer 5V-131 and I would like to upgrade the OS to W7 Pro. The only problem is the HDD that came with the notebook has a reinstall partition on the hard drive. If I take out the HDD and install a clean HDD and then install W7 pro will the MB see the modem and let me set it up wireless. No disc were sent with the notebook so I am uncertian how a clean install will work with the notebook. I understand my deck top because it came with a install disk for the MB. The notebook does come with a program that lets you make backup disc, but would that hold the info on the MB and how would you find that info??
