So let's continue our practice after our break and pretty cup of tea or coffee.
I have a multi-boot platform which consists of two Active, Primary SATA HDD. One of them has two Windows OS: Win XP and Win 10 ver, 1607.
The another one has Linux CentOS, which I have just installed.
So, my next step will be to make settings of Grub2
At first, I checked if os-prober would be installed in this system. Yep, I have done it.
Next: grub2-mkconfig -o /boot/grub2/grub.conf
Grub2 found Windows OS.
To work effectively, I decide to set X-Windows system and DE. My favorite DE is Mate at this moment.
So, I ran it: yum -y groupinstall "Mate Desktop"
Next:
systemctl set-default graphical.target (it's equal previous init 5 mode)
systemctl enable lightdm
rm '/etc/systemd/system/display-manager.service'
ln -s '/usr/lib/systemd/system/lightdm.service '/etc/systemd/system/display-manager.service'
