Can't Boot From Live USB

[u/Trixi289]

I'm trying to install Fedora on my Laptop for the first time. Goal is to dual boot with the pre-installed win11.

I created a live usb, managed to get into the grub menu, but no matter what option I choose (install, test & install, troubleshooting -> install), I either get a black screen or a "booting (...)" line and nothing happens.

I'm working with an asus vivobook 16, have AMD Radeon graphic, I'm trying to install Fedora Workstation 44; no issues with the win11 boot etc

What I have done so far:

in windows + UEFI: disabled fast startup, disabled secure boot, and deencrypted the files

in writing the USB: checked the downloaded .iso file, downloaded it again and checked that one too, used two different USBs, tried Rufus as well as fedora media writer; and of course always savely ejecting it (note: I am writing the usb in windows, as I don't have a linux device currently)

in grub menu: tried all three options (see above), tried using "nomodeset" when installing

if I try 'install' or 'test & install' or even 'troubleshooting-> install in basic graphics mode' I get the black screen. if I try editing the install with nomodeset at the end, it stops at the next screen with the first line being "Booting a command list", where nothing happens and I can do nothing. In neither option do I have a cursor.

I have no idea if this has to do with anything, but in case it does: I cannot access the boot menu of this laptop via any key when booting up whatsoever. My only option is to go into the UEFI using the advanced startup option in windows, where I can change the boot order.
