Hi I have tried everythin with this I am trying to install another os on my laptop which has both uefi and legacy.I get the error cannot install because of gpt.
I go into bios turn off secure boot, keep uefi , and try to add option for dvd drive because no option is there for it since I am using a dvd. No matter what, no dvd option is made or comes up.
Should I just convert the whole disk to mbr? Will i lose anything?
Is there a fix for the dvd bootup problem? Thks

Is it an internal or external DVD?
There is no way to convert GPT to MBR without losing the data but un can image the disk and restore files from it later.

Are you going to install in uefi or in legacy?
If the disk is gpt (uefi)
I can not install legacy
To install legacy you should clean the disk with
The diskpart command (search in google)
or vice versa

There's no need to convert the whole structure to mbr only to be able to access boot entry from a DVD. Did you try making ISO from DVD and then burn that ISO to USB using Rufus?
Note : converting from MBR to GPT and GPT to MBR shouldn't lead to data loss if done properly.
