Steps to Ubuntu Desktop 17.4 LIVE Boot Using ISO in CentOS 7

Ubuntu Desktop 16.4 LIVE Boot Using ISO - CentOS 7

Step 1:

Download Ubuntu From "http://releases.ubuntu.com"

  



 U14 - http://releases.ubuntu.com/14.04/ubuntu-14.04.5-desktop-amd64.iso

   U16 - http://releases.ubuntu.com/16.04/ubuntu-16.04.3-desktop-amd64.iso    

   U17 - http://releases.ubuntu.com/17.04/ubuntu-17.04-desktop-amd64.iso

Download: ubuntu 16.4

   mkdir /live

  

   cd /live

   

   wget http://releases.ubuntu.com/16.04/ubuntu-16.04.3-desktop-amd64.iso

   mv ubuntu-16.04.3-desktop-amd64.iso /boot/ubuntu17.iso

Step 2:

Add Menuentry on grub.cfg

Loopback Explantion :

The loopback line must reflect the actual location of the ISO file. In the example, the ISO file is stored in the / directory

X is the drive number, starting with 0;

Y is the partition number, starting with 1

sda5 would be designated as (hd0,5); disk 1 partition no 5

sdb1 would be (hd1,1); disk 2 partition no 1

Other Location Examples:

(hd0,5) /boot/$isofile , Located in the system's normal /boot partition on sda5

(hd0,6)/$isofile : Located in a separate boot partition on sda6

(hd0,7)/username/Downloads/$isofile  : Located in a separate home partition on sda7

(hd1,2)/iso/$isofile :  Located in the /iso folder of the sdb2 / partition

df -f

Here is ISO file path is /live on /sda2 , disk 1 & partatin no 2

  

vi /boot/grub2/grub.cfg
