I am proceeding under the assumption that you have access to another computer (with you posting on this site), and that you have admin/install rights on it. You also never stated what OS you were using so ill provide links for both Vista and Win 7.
First you will need to go to one of these two sites and download your appropriate OS recovery ISO (you will need to determine whether you have 32bit or 64bit OS)VistaWindows 7
Next you will need to burn the ISO image to a disk. For that you will need ImgBurn, and you can download that here
After you have downloaded the appropriate ISO and installed ImgBurn (make sure you do not install any toolbars while installing this program, I believe it will give you that option), you need to start ImgBurn. Once started you need to click on the Write image file to disk
button. At the top of the page it will ask you for a source (which is the ISO you downloaded). Click on the small folder button to the right and it will open another window so you can point it to the location where you downloaded the file. After you have indicated the appropriate file insert a disk, make sure you put a check mark in the Verify
box, then press the Write
button at the bottom.
Once the disk finishes burning you can use it to boot from a external CD/DVD drive that you attach to the netbook. I hope this is of help to you.
