Eggsactly my point ...
I think I am stuck with burning 2 discs ...
Might want to make sure with Acer before you continue this plan. I know on HP hard drives, depending upon the model, that the version of Windows 7 that is restored is locked to that specific hard drive, and a deep level reformat (or a replacement of the hard drive) can prevent it from restoring the backup media onto the computer.
Personally, I think you're pretty mad to be doing this - hours spent reformatting the hard drive, an hour making the restore media, another hour restoring the computer from media, hours spent removing the bloatware, hours more trying to make a second restore disc, more time reformatting the hard drive again, then trying the restore disc that may not work..
Just buy a new (and likely better) hard drive to go in the computer and an OEM version of Windows 7. No bloatware, no having to reformat the world.
