Hi. I've tried to install Fedora 29 in a 2011's Macbook Pro, which has its main GPU damaged, so I need to use the secondary Intel based GPU. I've Googled quite a lot about this, and I've managed to find information on how to install Ubuntu, and tried it, and it works for Ubuntu. The "trick" is passing some parameters to grub, and hense to the kernel at boot time... ok... when I try to do the same with Fedora, I'm not able to apply those paramater changes, because I need to type a key stroke combination, that for some strange reason it's not accepted/received by grub (on Fedora, but it's possible in Ubuntu). My question is: is there a way to change the grub config file directly into the instalation media (usb drive)?

What key combination? I'm curios, as do not remember any key combination modify your boot kernel parameters

you need to find the equivalent on your mac keyboard for "CRTL"

on the boot screen highlight the entry you want to boot (up/down key)


Key e   for edit

move the cursor just under the line containing initrd (something)

use left-cursor-key to get behind the last entries (rhgb quiet -sort-a). You may remove "rhgb quiet" to see more boot messages.

key in your parameter and double check what was written


CTRL + x

to boot with your parameter.
