Well, that didn’t work.

You’re performing a fresh installation of Windows 7 on an older Windows XP Professional desktop PC, but the Windows 7 installation media won’t boot from the DVD-ROM drive and always boots Windows XP normally. The Windows 7 DVD-ROM boots properly on other computers in the office. What is the most likely cause of this issue?

A) Windows XP SP3 security features won’t allow booting of DVD-ROMs

B) The Windows 7 DVD-ROM is too new to be read by the DVD-ROM drive inside of the computer

C) The Windows 7 DVD-ROM is damaged

D) The BIOS is not configured to initially boot from the DVD-ROM

E) The computer is too tired to boot the DVD-ROM drive
