Step 8: I cant create new partition , All option is not visible . I cant able to click the new option and create new partition.
If the laptop's HDD has been set up with an MBR partition rather than GPT, then the maximum number of primary partitions will be 4. It could be that the drive already has 2 other partitions, one of which could be used for storing a backup of the OS for rescue purposes. Also, Windows 7 usually has a small (~100MB) partition at the beginning of the drive.
Try creating one primary partition and one extended partition. Then create two logical drives in the extended partition.
