I recently dual booted linux mint on my laptop, and I came across the infinite squashfs error (an infinite amount of "SQUASHFS error: Unable to read page" and "SQUASHFS error: Unable to read data counting up, I think because I took out the usb and pressed enter too quickly) I couldn't do anything, so I shut down and restarted, upon restart, its running fine? No corruption.
Edit: I reinstalled and waited a while after unplugging before and enter did not work, I hit escape and this happened again, though text is bigger and slower
I had this or a similar issue right after installation many times. I force rebooted and everything was fine. I wouldn't worry about it too much
