No. Don’t worry.
Since it is crashing right at the Boot Splash, this suggests a graphics conflict during boot. You have several options available for how to access your default grub file.
Option 1.) Boot as normal but hold down the Left Shift key during boot up to pull up the Grub Menu. Once you see the menu

hit the ‘e’ key. This will open the Editor mode for grub.
This screen should look like:

You see the line that says
linux /boot/vmlinuz-2…496a ro quiet splash
Use your arrow keys to navigate the cursor to the end of “splash” on that line and add “nomodeset”.
So it should then look like
linux /boot/vmlinuz-2…496a ro quiet splash nomodeset
Once done and no typos made:
Hit ctrl+x to start the boot process. You MAY need to try rebooting a couple times. If this does not work, please report your findings.
