Pop OS doesn't boot up because of pci-e bus error

So, today I downloaded the iso file of the new Pop OS 18.04 in order to try it out.

However, after I created a bootable usb, I opened my laptop, and chose to boot from usb, and suddenly I got a kind of loop that says “PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID)”

I got this error in the past, and I still get it every time I boot up Ubuntu, or Ubuntu based distros, but it stops after a moment. In this case, it doesn’t.

In theory, I could fix this problem, by adding “pci=noaer” to the grub file, but I can’t do the same thing here, because I can’t install the OS so I don’t even have a grub, or a way to access the terminal.

Is there any way I can fix this problem? Or maybe find the grub file on the USB?

EDIT: I am using a 6th generation intel cpu+hd graphics card. 8gb of ram, and 1TB of storage.
I have already asked a question about this error, and I have seen many others ask the same thing, so, adding the line above will fix the problem.
Also, my laptop uses BIOS and not UEFI

Thanks in advance ?
