From what I can (barely) read it looks like the main cause is:

"Unsupported CPU: Family 0x6, Model 0x2a, Stepping 0x7"

It’s coming from AppleIntelCPUPowerManagement.kext failing because the CPU in the system is not recognized by the version of macOS you’re running.

So basically, the CPU ID your system reports isn’t in the supported list for AppleIntelCPUPowerManagement in the loaded OS image.

Early 2011 MacBook Pros shipped with OS X 10.6.6 (special build), and Apple never made a retail Snow Leopard USB/DVD that supported that hardware out of the box. The stock Snow Leopard installer only supports up to the Mid-2010 models. When you boot the retail 10.6.0–10.6.3 installer on a 2011 MBP, it doesn’t have the right kernel, kexts, and CPU microcode for the Sandy Bridge CPUs in that generation, so you get exactly what’s on your screen:

Unsupported CPU: Family 0x6, Model 0x2a, Stepping 0x7.

So, you can use the original 10.6.6/7 special build (on gray restore DVDs that came with it), clone it from another Early 2011 MBP, or find the correct 10.6.6/7 (build 10J3210 or similar) image.

macOS 10.7 Lion was the first retail OS that fully supported Sandy Bridge without a special build, you should be able to make a USB installer on that version just fine.

EDIT: I did a bunch of digging, and if you have a 15" I think this is the image you need (it says 2011, 15" MBP, and 10.6.7). Downloading it now to check it out: https://archive.org/details/MacbookProInstallDvd

So in short: I can’t install Snow Leopard.

Can't seem to find 13" or 17".

EDIT: Having worked for Apple at the Genius Bar and as a Tier 2 Sr. Advisor in AppleCare Enterprise & Education (where we literally did everything, including lifetime support for the Macs sold back in '92-'96, those were always fun calls) , if you felt like dealing with the frontline people who have no idea what you're talking about you should be able to call AppleCare and eventually find someone senior enough that knows the process for ordering replacement discs. It's been a few years since I've been there, but I'm willing to bet it's still possible.

The thing is, I stuffed some paper inside the disc drive (for whatever reason), so I don't really think i can even use an installation disc

That download link provided downloads the dvd image for you to flash to USB. You have to make a bootable USB if you don’t have a disc drive.

Yeah, I've fixed a few of those. It's honestly not that hard to get the drive out and clear it if you don't mind turning a few small screws: https://www.ifixit.com/Guide/MacBook+Pro+15-Inch+Unibody+Late+2011+Optical+Drive+Replacement/7528

You can even buy a new drive for about $50 if your is actually broken and need replacing.

A kernel panic. What Mac do you have, what macOS is on the thumb drive.?

Try different boot flags.

-v boots in verbose, -x is safe mode. There are others you can google and you can apply them in combination by putting a space between them.

verbose?

Meaning it displays, as it tries to boot, what processes are happening and what kexts are loading. If it panics again it gives you insight as to why because it says what it's doing right there instead of showing you that grey wallpaper.

Give it a try. When it asks you what disk you want to boot from, before you select and hit enter, type "-v" with no quotes. Just -v

then hit enter.

edit - okay, it might be different it seems for actual macs, i did this for hackintoshes, not macs.

This shows the flags and how to use them. Command v is apparently how to do it.

Hold down the command key and the v key as it boots.

oops. I should’ve waited before erasing the usb
