Good afternoon from Singapore,
I need SERIOUS help on GRUB in CentOS 7.5 1804.
Please refer to my installation notes at http://lists.linuxfromscratch.org/pipermail/lfs-chat/2018-October/028964.htm...
According to Petros' instructions, I need GRUB Legacy 0.97 for my Extremely Simple Linux. But GRUB Legacy 0.97 has been deprecated in CentOS 7.5. GRUB2 is installed by default on CentOS 7.5.
So I defied Petros' instructions and used GRUB2 for my Extremely Simple Linux compilation, with the end result that I do not see any operating system selection menu on GRUB2. What I get is a grub prompt and I need to enter the following GRUB2 commands:
grub> linux /boot/vmlinuz-4.18.12 root=/dev/sda1 ro quiet grub> boot
(1) If I seriously want to use GRUB2 for my Extremely Simple Linux, I would need to modify /boot/grub/grub.cfg to suit GRUB2. Because Petros' /boot/grub/grub.cfg is meant for GRUB Legacy. Am I right? I am no expert on GRUB.
(2) If I want to use GRUB Legacy for my Extremely Simple Linux, I would need to use CentOS 6 instead of CentOS 7?
(3) If I insist on using CentOS 7.5, is there any way of getting rid of GRUB2 and installing GRUB Legacy instead?
If you watch my short 2-min YouTube video at https://www.youtube.com/watch?v=YrJADssqaQU , I am not getting any operating system selection menu on GRUB2. I am getting a grub> prompt only.
Please advise.
Thank you.

Now I will need to learn how to implement GRUB2 for my Extremely Simple Linux.
Thank you.

Using Windows 10 to run CentOS 6 under Virtual Box, using Putty to log into CentOS (what?) and rebuilding a bunch of programmes from source isn't "Extremely Simple".
