Step 1)   Download Ubuntu 18.04 LTS ISO File

Since Ubuntu 18.04 LTS only comes in a 64-bit edition, so you can install it on a system that supports 64-bit architecture.

Step 2) Create a Bootable Disk

Once the ISO file is downloaded then next step is to burn the downloaded ISO image into the USB/DVD or flash drive to boot the computer from that drive.

Also make sure you change the boot sequence so that system boots using the bootable CD/DVD or flash drive.

Use LVM with the new Ubuntu installation – Choose this option if you want to use LVM based file systems.

  1. burned a dvd from a windows 10 laptop and did an install on a windows 7 laptop. Windows 7 would never burn the dvd. The install never asked to run trial or install, no language screen, no keyboard layout screen. no installation type, no partitioning. It just did an install on it’s own parameters that I didn’t choose, Ubuntu did launch, mouse works, keyboard doesn’t. Small wonder. What am i missing?

  2. My laptop told me to disable iRST, I have 1 TB SSD and no HDD. can I install ubuntu? or is it not possible/safe to create partitions in SSD?
