Hi, I updated my Vista DVD by integrating 300+ hotfixes into the install.wim (using vista master udpate pack). I have burnt the DVD. I can see that DVD is bootable, files can be read from DVD and copied to HDD without errors. This DVD has only Vista + Hotfixes integrated (from master update pack) nothing else. However, when I insert the DVD and restart the system, after 5-10 seconds, the computer starts to BEEP. It does not boot into Vista Setup. The BIOS settings are proper and I am able to boot from other normal Bootable CDs/DVDs. My system is a 2.6 GHz Intel board with 512 MB Ram. What could be wrong? Pls help.
