Problem.

I've been attempting to boot from the DVD with no success. I've set the boot order( as shown in the attachment, which I hope you can see). When the PC boots up I'm shown " hit any key to boot from CD/DVD". When key hit is shows Windows Loading Files?. Once completed, it shows Windows Loading (with what appears to be three colored dots). Then the system freezes. If key not hit it goes into Windows as normal.Obviously something/somewhere is not properly set,but what?
I've backed up this system using Macrium Reflect and have been trying to boot from the rescue disk.
I've also tried the Paragon rescue disk with the same results.

I backed up my other systems XP and Vista without any hiccups, but no joy with 8.

Any help would be much appreciated.overthehill

Update.

After resetting start-up to default(which is to boot to HD 1st) and resetting boot order to boot from CD/DVD 1st , now when I boot up I'm shown a message(in red box) that states.

Secure Boot Violation.
Invalid Signature Detected
Check Secure Boot Policy in Setup.

I went to Authentication on same screen and it's set as follows.

System Boot State ---  User
System Boot Mode State --- Enabled


Secure Boot ---{Enabled}
Secure Boot Mode --- {Standard}
Default Key Provisioning ---{Enabled}

Any idea if any of this should be changed or any other ideas would sure be appreciated. overthehill

Since you have come this far here's how to disable it::

    Enter the computer's firmware utility by pressing Del during the initial stages of the boot process (before any boot loader appears). Some computers use other keys for this purpose; examine your early boot-time messages or read your computer's manual to learn what to use.
    If you're configured to boot in EZ Mode, press F7 to enter Advanced Mode.
    Click the Boot tab.
    Click Security Boot Parameters near the bottom-left of the screen. (It's conceivable you'll need to scroll down to see this on some systems.)
    Change OS Type from Windows 8 UEFI to Other Legacy & UEFI. The Secure Boot Mode and Key Management options should disappear.
    Press the F10 key to save your changes and reboot the computer.

It can be re-enabled after you have finished your tasks.

Thks, patio for responding. I get into setup pressing the delete tab. (Now here's where I'm lost.) Whether or not it's configured to EZ Mode I don't know? Pressing F7 doesn't work. When in setup I see Advanced on the same line (up top) as Boot Options. Is that the Advanced Mode? If it is there are no options as you have described below(Click Security Boot Parameters etc.etc.)

Update: 
Being brand new to Win 8 I did some Googling and found an "Advanced Start up" option.
This states; "Start up from a device or disc(such as USB or DVD), change your PC's firmware settings,change Windows start up settings, or restore Windows from a system image".
This will restart your PC.  RESTART NOW !

Is this an option? Having no real back up for this PC I'm leery of clicking that button. Need your guidance. Thks., overthehill

Problem solved but see no"Solved" option.

1) "Disabled" Secure Boot
2) Launch CSM to "Always"

Now I can set boot order out of the BIOS. overthehill
