I just burned the GParted Live on CD to start the installation of Windows on IBM laptop operating on Ubuntu 12.04 LTS.

What are the elementary basics to boot CD on laptop?

For example, what is the step by step process (i.e. changing BIOS to recognize CD when booting)? Are there any specific screens, commands in this process?

You should not use GParted to install Ubuntu, please use the installer included with the CD! –  Braiam Aug 1 '13 at 23:00
Braiam, Ubuntu is already installed on laptop. I'm attempting to install Windows OS as a 2nd O/S. –  user179586 Aug 1 '13 at 23:08

Ok, first of all, DO A BACKUP of your system! Once you have done this, you can continue reading:

After you have done your backup

Prerequisites: A Ubuntu CD/USB. The GParted CD won't be useful since you can have gParted on Ubuntu, but without Ubuntu you cannot continue.

  1. Set your BIOS/UEFI to boot from the CD first.
  2. Insert the CD where you will use gParted. Boot your system.
  3. Open gParted, if it's not open.
  4. You should verify this:
    • You must not have more than 3 primary partitions.
    • You can't move the start of any partition.
    • You have a partition you can reduce the enough space to install windows.
    • If you have a /boot partition and where.
  5. Select a partition to resize and reduce until you have a No assigned space big enough to install Windows.
  6. Wait.
  7. Create an NTFS partition on this new space.
  8. Reboot.
  9. Insert your Windows DVD.
  10. Be sure to select your NTFS partition and install it.
  11. Wait till it ends.
  12. Shutdown Windows normally.
  13. Insert your Ubuntu CD and select boot repair.
  14. Click "recommended repair".

On other cases or if you don't have the "boot repair" option check https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows

Braiam, many thanks. I have to learn how to do the backup of system. I know this may appear extremely elementary, but up to a few weeks ago I've only worked with Windows and Mac OS. As far as a Ubuntu CD, I suppose I can download the OS from the web. –  user179586 Aug 2 '13 at 0:31

Your question isn't very related to Ubuntu, though your steps should most likely be:

  1. Enter your BIOS setup - via some key advised at the black & white screen immediately after you turn on your computer (like F10 on a HP notebook).

  2. In the BIOS menu look for a "Boot order" or similar, then select your CD drive as the first medium for your computer to load operating system from.

  3. Put the Gparted to the CD drive, Save the changes in BIOS setting and your computer will restart and should launch (=boot) from the CD.

  4. When you'll run gparted, you'll see your hard drive and the partitions on it. If there is none "unallocated", you have to take some space of an existing partition. Select one, right click and select "resire/move" command. Make the partition smaller and an "unallocated" partion will appear. Make sure it will be large enough to install the Windows OS.

  5. Turn of your computer and place the installation CD of Windows into the drive. Then ...hope for your best. (Sorry I just realized I'm not sure about the way to make the things working the way you'd like.)

Hugo, thanks. The laptop is an old IBM Thinkpad; I'll have to figure out how to get to BIOS menu screen. –  user179586 Aug 1 '13 at 23:49
