    No - you can boot from any dvd that is UEFI secure boot compliant - eg Windows 8 dvds, some linux dvds, many image backup tools eg Macrium Reflect etc.

    I tried turning secure boot off in the bios, but it is still the same.

    You have to turn off Secure Boot, and enable CSM mode to Boot older BIOS type boot media.

    Try booting using (F8). Select your DVD/CD player. Start your computer and start tapping the (F8) key until you get the boot selection.
    Sometimes that is the only way to boot a bootable CD/DVD.

    This did the trick :)
    thanks a lot everyone...

    Now i got an other issue, i cant boot from the older BIOS type media, and still see my GPT partitions, or use keyboard or mouse when i do it.

    Im not sure if i should start a new help thread for this, but...

    The real issue is that my "older" pc fried 2 gfx cards, so i got a new computer as i wont risk another gfx card on finding the defect hardware. but i need access to data on my old harddisks, but they are GPT locked, and my new computer cant access them.

    I tried converting the disk back to MBR with EaseUS partition master, but it sees it as MBR, but it is GPT..

    PC cant read bootabe CDs except for the Windows 10-easeus.png

    So now i tried with several other ones, and AOMEI Partition Assistant Standard sees it as GPT and have the option to convert it into MBR, but when i start the process im getting

    - error code 4 (
    Failed to lock the volume, please reboot and retry.) or

    - error code
    6 (The partition table on the disk failed to update as other programs locked the partition table, please close other programs and retry.)

    I tried to follow the instructions but with no luck.

    Deleting the partition is not an option as i need the data on it...
