Hello, I have a Toshiba laptop (Satellite C55-B5270) running Windows 8.1 and cannot boot from the CD/DVD drive. The 8.1 is OEM. I have disabled Secure Boot and changed the boot order to this drive. The CD is recognized by Windows 8.1 and I can read all the files on it. However, when I load the CD and start the laptop, it goes into Win 8.1 instead of using the boot CD. I have verified that the changes to UEFI were made and saved. 1st boot is the CD/DVD drive. Secure Boot is disabled.
Also, I have used this CD on my Windows 7 laptop and, after changing the boot order, I was able to boot from the CD and run a utility program. The creators of the CD stated that it had been tested and should run on Win 8.1.
I have researched and tried everything, but have hit a wall. All help would be greatly appreciated.
