You will need to make space for Ubuntu.
--Shrink one of the NTFS data partition, say the 6th partition of 294GB and make space for Ubuntu. 30GB of for Ubuntu is a recommended minimum.
After Shrinking you will leave the space as 'unallocated space'. But before you Shrink the NTFS partition run 'defragmentation' a couple of times on the paritition.
--Then run 'chkdsk' on the Windows Partitions... this will take care of the filesystem errors, if any.
--Reboot a couple of times to make sure there are no errors.
--Boot with Ubuntu DVD/USB and 'Try Ubuntu (Without Installing). Test Ubuntu on your machine. Check internet, wifi and check all the hardware you plug in to the machine and see if they all work with Ubuntu.
**Some Graphic Cards can cause 'black Screen'. As a temporary workaround you need to append 'NOMODESET' option to the kernel line to boot Ubuntu in a 'failsafe graphics mode'.
--Install Ubuntu from desktop.
--Follow the Install Wizard. When you reach the 'Installation Type' dialog choose either:
1. Install alongside Windows - the installer will setup Ubuntu in the 'unallocated space' we created earlier.. and continue with installation.
2. 'Something Else' option to manually create partitions from the 'unallocated space'.
Select the 'unallocated space' and make two partitions from it (asuming you have 30Gb space):
28Gb for Ubuntu '/' and set it up with
Use As= Ext4 Journaling system
Use As= Linux SWAP
continue with installaiton.
