I want to install Ubuntu 14.04 on my PC and remove Windows 8 without losing any previous partitions or data. I have booted my pendrive for installing Ubuntu 14.04 but I do not know how to install Ubuntu 14.04, remove Windows 8, and preserve all my data using the installer options.
This is how I will do it,
1.Make some free space/unallocated space ( about 50 GB ) by shrinking or deleting volume from current partitions ( using windows ).
2.boot ubuntu installation media.
3.now in the "installation type" select "something else".
4.add 3 partition -
i. select type > primary, allocate size > 20GB as ext3/4, mount point > /
ii. select type > logical, allocate size > 26GB as ext3/4, mount point > /home
iii. last of all 4GB as swap
That's all set for installation.
If you want to remove your windows partition just format/delete it after installing ubuntu ( after removing your needed files ).
NTFS file system can be mounted in linux using ntfs-3g & can be used natively.
Then run update-grub as root ( sudo update-grub ).
note: You can set your desired partition size according to your need or can expand it later.
