Cannot boot to the Active@ Boot Disk for Windows CD-ROM. The error CDBOOT: Couldn't Find BOOTMGR appears.

Suggestions: Try changing the disk controller in BIOS from AHCI to ATA - see if that helps.

Since we recommend changing a BIOS setting please note: if you changed the BIOS setting, you will probably need to change it back when you are finished with boot disk in order for the computer to boot into a regular Windows boot.
