What To Do
To boot from external medium you will need to have the following in place;
- CDROM or USB Device set to boot first in BIOS
To allow continue booting from external medium at POA, you will need to have the following policy (option) item set:
- ~ Authentication (Access): User May only boot from the hard disk = No.
Once you have logged on past the POA, you should now be able to boot from external medium.
Please note: It is possible that all these items are correct, and the BIOS still will not allow hand off from the HDD (the POA effectively) to the CDROM or USB Device.
The option to boot from an external media after POA has been removed as of version 6.10.
