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
