Vista won't start from DVD
I have successfully used my Vista installation DVD to backup and restore
Complete PC many times. But yesterday, it suddenly stopped booting and
no longer prompts me to "Press any key to boot Vista from the
installation CD/DVD". Other computers boot fine from this DVD, so it's
Apple MacBook Pro "Core 2 Duo" 2.33 GHz 3 GB RAM
Windows Vista Ultimate 32-bit
The only changes to the system configuration since the last successful
boot from the DVD (literally the night before):
1. Automatic Security Update for Microsoft XML Core Services 4.0
Service Pack 2 (KB936181)
2. Automatic Update for Windows Vista (KB947562)
3. Changed location of Documents, Videos, Music, Pictures to USB HDD,
and then reverted back to defaults.
What should I look into? Any help is appreciated.
