Hello Tn4Bama, and welcome to Seven Forums.
Yes, that DVD will allow you to do a clean install with it.
Clean Install Windows 7
Of course, to be able to install a 64-bit Windows 7, your computer will also need to meet at least the minimum requirements below:
- 1 GHz 64-bit processor
- 2 GB RAM for 64-bit Windows 7 (recommend at least 4 GB)
- 20 GB available hard disk space (recommend at least 60 GB)
It would also be a good idea to make sure that you have 64-bit Windows 7 drivers available for all of your devices, and to have them downloaded and ready to install after Windows is finished installing.
Hope this helps,
