I don't think there is enough free disk space to install Ubuntu on this
machine.

* I deleted the last partition E, so there was free space @158 Gb for
ubuntu installation.

* If I am not clear, I would like to explain my problem once again without
hijacking the thread.

I am having a Dell Laptop Inspiron 17  Model 3721 with Window 7 64 bit
pre-installed. The configuration are i5 /6gb/ 750gb HDD.

The HDD is having 5 following partitions as per windows disk manager.
1, OEM partion 39mb (Shown as primary)
2, Recovery partition 29 Gb (Shown as primary)
3. C: Primary partition 352 Gb (Primary)
4. D: Logical  partition 166 Gb
5, E: Logical partition 158 Gb

In the laptop bios, legacy boot is enabled and secure boot is disabled. My
intention was to install Grub boot loader in the /boot partition and use
the default Windows boot loader by appropriately modifying the entries
using Easy BCD (to overcome any unforeseen problem while the nagging
upgrade to Windows 10 happens). Though I can use Ubuntu, still I need to
keep windows.

To Install Ubuntu 14.04 LTS booted from the DVD, deleted the last partition
E to create free space. As I am already having 3 primary and 1 logical
partitions in the HDD, I created /boot and /root partition as logical
without any problem. When I proceed to create /home partition that too
logical the system was busy for more than 3 hrs and nothing happened. So I
shutdown the system and rebooted to Windows.

To find a solution for this problem, I googled a bit and came across the
following:

The 4-partition limit no longer exists with disks that use the GUID
Partition Table (GPT). 
GPT supports up to 128 partitions by default and does not include the
concepts of primary, extended, or logical partitions (although many tools
refer to all GPT partitions as "primary partitions," simply because those
tools were written with the older MBR system in mind).

Intel-based Macs, the vast majority of computers that shipped with Windows
8, and some computers that shipped with Windows 7 (particularly beginning
in mid-2011) all use GPT. Most PCs sold before mid-2011 use the older Master
Boot Record (MBR)  system,
which is limited to four primary partitions, one of which may be an
extended partition that can hold an earbitrary number of logical
partitions. Thus, increasing numbers of readers of this question are likely
to find that there is no problem; if the disk is partitioned using GPT, the
4-partition limit simply doesn't exist.

After reading the above, my questions are whether is it possible to install
Ubuntu by creating all the partitions as logical?
Is it mandatory to have all the Linux partition as primary? If not all,
what partitions should be created as primary?
How to ascertain GUID Partition Table (GPT) is used in a computer ( My
laptop was shilled in 2013)?
Is it possible to change windows primary partition into logical (except C:
the boot partition) using Ubuntu partition utility while installing?

Thank to Arun Khan and others for patiently reading my post and suggestions.

Regards

Good suggestion but ...

I suggest that OP report the output from a Live Boot session.  It will
give a priori information about how the disks are partitioned by the
vendor for the OEM OS.

Let me thank members who responded to my mail.

#1 Why are you creating logical partitions? You can create up to four
primary partitions.

The Windows HDD is having 5 following partitions
1, OEM 39mb OEM partion (Not sure logical or primary)
2, Recovery partition 29 Gb (Not sure logical or primary)
3. C: Primary partition 352 Gb
4. D: Logical  partition 166 Gb
5, E: Logical partition 158 Gb (In this partition I wanted to Install
Ubuntu 14.04 LTS)

As I am not sure whether the first two partitions or primary or logical, I
preferred to create linux partitions as logical to overcome the limitation
of not exceeding four primary partitions in a HDD.

#2 You do not need 1 GB for /boot. Try installing with separate /,
/home and swap primary partitions.

Of course, I can reduce the /boot partition size to 500 mb. I preferred a
/boot partition to install boot loader there to use windows  boot loader
instead of Grub 2 to avoid issues when upgrade to windows 10.

#3 Can you also check if there are no other primary partitions on the
hard drive?

There is one known primary partition C: and two more; OEM and Recovery
partitions of Windows 7 (logical?).

As somebody suggested, I can also wait for the release of Ubuntu 16.04 LTS.

[Ilugc] Ubuntu 14.04 LTS dual booting with Window 7 Partition problem

2016-01-26 Thread Dhanagopal R 
Hi

I attempted to install Ubuntu 14.04 LTS 64bit in my Dell laptop (Inspiron
17 3721  i5/ 6gb / 750 gb HDD / Windows 7 pro) to dual boot. In the laptop
legacy bios was enabled and secure boot disabled. I booted the system using
the downloaded ISO DVD and  did the following steps:

1. Deleted the empty 170 gb Windows NTFS partition to create free space.
2. Selected the free space using the Ubuntu partition utility
3. Created 1gb /boot logical partition ext4 - no problem
3. Then created a 30 gb / root logical  partition ext4 - no problem
4. Then created a 130 gb /home logical partition ext4 - There was problem.
I could not proceed to create /swap partition.

After clicking OK, home partition did not get created. It was showing busy
icon for more than two hours. Then I clicked the cancel button. There was
no response for another one more hour. Only the busy icon was displayed.
Then I am forced to shutdown the system, removed the DVD. Rebooted into
Windows and checked the disk partition, all the partitions including the
deleted one remained intact as NTFS.

Earlier I had installed different versions of Ubuntu in many laptops and
desktops (dual booting). I find this problem strange and also googled a
bit. Some people have reported similar issue i.e. Ubuntu partition utility
taking longer time to create ext4 file system.

I shall be thankful if someone from ilugc suggest me a solution.

Not sure how new your laptop is i.e. chipset.   Suggest you try 15.10.

I have installed 15.10 on a newer Dell laptop (last summer) and things
installed w/o any issues.  I did not have to tinker with drivers; all
devices (including keyboard back light, touch screen) are working out
of the box!  I plan to upgrade the OS when 16.04.1 LTS is released by
summer 2016.
