I'm new to Linux. I started learning recently. I'm learning it my own by watching online videos in Udemy and YouTube. I installed Centos8 in VirtualBox. The lesson I'm learning that how to switch to "rescue.target" mode. I interrupted boot process and pressed "e" from keyboard and found out my screen is totally different then then video I'm watching. I can't see the if else section the whole section is missing for example the following line is not there.
"linux16 /vmlinuz-3.10.0-327.e17.x86_64 root=/dev/mapper/centos-root ........................."
I'm attaching both of the screenshots. Any idea why it is missing? or I did anything wrong? I'm also noticing that last few days it is taking more time to boot.
Thank you for you help.

Re: linux16 line is missing from boot screen
The video is from ancient CentOS Linux 7 system. The GRUB package has received some 90 updates between that and your CentOS 8.
It is the "linux" line that has kernel command line options "($root)/vmlinuz .. rhgb quiet". That is the line you add to/modify.
