  • Was this your issue before reinstalling Windows with fewer primary partitions? http://askubuntu.com/questions/149821/my-laptop-already-has-4-primary-partitions-how-can-i-install-ubuntu – oldfred Aug 20 '15 at 03:41

I have installed win 7 normally, made 2 partition please make note its in MBR

  1. 100 mb system reserved

  2. 50 gigs for my win 7

  3. Left rest as unallocated

Now after the installation I rebooted the and booted with bootable ubuntu USB

I am not able to see option “alongside” so selected something else

Then coming on to Ubuntu partition (doesnt matter under GPT primary or logical. But if its MBR then strongly logical)

1.20gigs mounted to / (at least 10 gigs required)

2.20gigs mounted to /home ( at least 10 gigs required)

3.10 gigs swap (double of RAM preferred)

4.You may have to create a partion in ubuntu as Fat32 if you want to move files from ubuntu to windows or vice versa (size depends on you requirement and needs. ALSO ITS NOT A MANDATE DRIVE ITS OPTIONAL.)

Then install Ubuntu make sure the directory should be /dev/sda

Once installed reboot your laptop, after reboot it will boot with Ubuntu.

Now to make windows visible we have to update the file named Grub hosted under - /etc/default/grub

To update and make the change in a statement -

GRUB_TIMEOUT=10

And

GRUB_TIMEOUT_HIDDEN=10

For this go to terminal

Type GRUB_TIMEOUT=10 enter then

Type GRUB_TIMEOUT_HIDDEN=10 enter then

Type sudo update-grub enter

Restart the computer I am sure you will be able to see option to choose between windows and Ubuntu

Happy ubuntuing ……….. 

I am so glad finally I did it ……yayy
