Explanation
Windows 7 installation media is distributed on DVD, not CD. The Windows 7 installation files are too large to fit on a CD (which holds ~700MB), so a DVD-ROM drive is the minimum optical drive required to read the installation disc. A DVD-ROM drive can only read DVDs (not write), but that is sufficient for installation purposes. DVD-RW can also work but it is not the minimum - a read-only DVD-ROM is sufficient and less expensive. Blu-ray is more than capable but unnecessary and far beyond the minimum requirement. A CD-ROM drive cannot read DVDs and would be unable to boot or read the Windows 7 installation disc.
