I have downloaded ubuntu 16.04 from the official website and tried to install it alongside Windows 7.

The following are the steps i have followed:

  • My C: drive is partitioned with 100GB and I have unallocated 40GB of space to install ubuntu in the C: drive.
  • While installing I don't see the Install ubuntu alongside Windows 7 option, so i have chosen "something else" option.
  • The 40GB unallocated space is shown as unused space, it didn't let me use this 40GB space, so I chose other partitions space and set 4GB for swap and the rest to root
  • In the end I selected Windows load manager and continued the installation
  • The installation successful message was displayed and upon restaring the system neither was Windows 7 on my drive nor Ubuntu.

I have tried to search some solution for this but couldn't find any.

How can I dual-boot my system correctly?
