First: Backup your data from Windows 8 partition if needed.

Don't worry. Windows 7 will be intact if you take care while installing Ubuntu.

To remove Windows 8 refer to this and this.

If not not deleted the Windows 8 partition then from your Windows 7 OS, delete the Windows 8 partition through Disk Management, which can be brought up by right-clicking the My Computer icon. Reboot to see and confirm the changes.

Now with a live CD or live USB flash drive of Ubuntu 12.04, you are ready to go.

  1. Boot from the live CD or live USB drive. Use the Try before Install option, or if you want to install directly then choose Install option.

  2. Proceed with installation steps. Select the first default option Install Ubuntu alongside Windows 7 for ease of installation. (sorry for the wrong optioned screenshot).

enter image description here

Then at the Partition table, select the Free space or Unallocated space.

--Select the Add option and then allocate the desired Space for root / and swap partitions in ext4 format [search or refer to Ubuntu Guide for the minimum and your RAM based swap space requirement, or you can also select the Something else option for manual partitioning. If you want different partitions for /home, /boot, etc. you can allocate them in the same way.

-- Then select the appropriate drive at the Grub Bootloader Installation option, if there's only a single hard drive then most probably it will be sda . And it's done.

You can refer further to the Official Windows Dual Boot wiki.

Its possible.

  • First thing you need to do is to backup all your important data if you have any from Windows 8. Then go to your Windows 7 disk management utility and format the partition containing Windows 8. I assume here that you have installed win7 and win8 in different partitions.
  • Now, once you are done with formatting that partition with NTFS. Install a software called as daemon-tools or PowerISO, they emaluate ISO such that you will be able to run your Ubuntu 12.04 iso file without burning a CD.
  • Then all you need to do is to use WUBI, its a installer of Ubuntu inside windows(means it won't modify or format your hard drive and there is no risk of data loss).Using that you can install Ubuntu 12.04 easily.

Also Here is a link of how you can use WUBI. Using Wubi

If you are a beginner i will suggest you go this way, it will give you least troubles.
