Hey everyone! I'm running into a frustrating problem with Linux. Right after selecting my OS in GRUB, my screen goes black and I lose video signal; nothing shows up on the monitor, not even the logo. This issue persists across various distributions including Linux Mint, Cachy OS, and Pop!_OS. I can boot normally when using the 'nomodeset' option, but without it, nothing works at all. This problem also occurs during installation, requiring the use of 'nomodeset' every time. I'm using an RX 550 4GB graphics card and an i5-3570 processor. I really want to install Linux on another SSD to get familiar with it, but this issue is driving me nuts!

Thanks for the tips! I actually tried a bunch of different solutions including some driver options, but here's the kicker: swapping cables and plugging into a different monitor input solved the issue completely! I had no idea my cables could be the problem, but it turns out they were faulty. Funny how something so simple can cause so much trouble, right?
The 'nomodeset' option is key here because it prevents the kernel from loading video drivers, relying instead on BIOS settings until the graphical interface (X) loads. This can cause issues if there’s a compatibility problem between your hardware and drivers, leading to that black screen. You might want to switch to command-line mode temporarily using TTY to troubleshoot further. You can do this by pressing CTRL + ALT + F1 to get to a terminal. Once there, you can try updating your video drivers or adjusting settings. There's a helpful guide on TTY you can check out for more details!
Have you tried disabling Secure Boot in your UEFI settings? Sometimes that can interfere with booting Linux, especially if you’re using certain GPUs. When you start your PC, press the key to enter your BIOS/UEFI settings and look for Secure Boot. Turning that off might help with your boot issues.
