Question 1

difference grub grub2, files and LVM support

Answer 1

Grub has two configuration files namely menu.lst and grub.conf whereas, Grub2 has only one main configuration file namely grub.cfg (/boot/grub/grub.cfg)

The /boot/grub/grub.cfg file is automatically generated by grub2-mkconfig using templates from /etc/grub.d and settings from /etc/default/grub

grub-install installs GRUB onto a device

/etc/grub2.cfg is a symbolic link to the grub.cfg

Grub uses physical and logical addresses to address the disk, it can’t even read from new paritions whereas, Grub2 uses UUID to identify a disk thus is more reliable. It supports LVM and RAID devices.
