Migration from Windows to Ubuntu

Asked by Faisal Javed on 2010-03-25

I had downloaded Ubuntu using windows OS (Win7). I wish to remove Windows from my system completely.
I wish to understand how I can do this and whether it will effect my system bootup or not?

I only want to use Ubuntu on my system, is this necessary to keep both OS as windows is my parent OS? If not how I can format my windows partition and remove Win7 from my system.

Thanks in advance.

Please look on http://www.ubuntu.com/getubuntu/download at step 2 "Burn your Ubuntu CD" or
https://help.ubuntu.com/community/Installation/FromUSBStick.
Then when you booting the live image from your media, there is a very nice wizard for installation on the hard disk.
The installation ask you what you want to do with partition table, partitions and MBR.

Thanks for your answer, much appreciable.
I actually downloaded Ubuntu in another partition of hard disk. I wanted to know can I format that partition of Hard disk in which I have Win7 and use Ubuntu without any hassle?

Regret, as I was unclear earlier.

Maybe Wubi is your solution.
"The Windows-based Ubuntu Installer (Wubi) allows you to install and uninstall Ubuntu from within Microsoft Windows. It lets a Microsoft Windows user try Ubuntu without risking any data loss due to disk formatting or partitioning. "
https://help.ubuntu.com/community/Wubi

Unfortunately I have not experience with Wubi.

I have had downloaded Ubuntu. Configured it to use and using it efficiently. Windows 7 is present there (30GB space) along with its component and softwares. I wish to remove all windows based softwares and Win7.

Can I do this using Ubuntu with destroying my data?

Hi Tuxar,

Just wanted to update you on the installation I have done:
I downloaded the wubi for Ubuntu 9.10 nad then did the installation using it.

and NOW THE MBR has 2 OS: Ubuntu and WIN 7.

My question is: HOw do I remove the WIN 7 and free up my disk? or in other words how do I remove the windows 7

Hi Faisal ,
Can you drop the output from the command?
fdisk -l or sudo fdisk -l

The output will be something like the below
user@host:~$fdisk -l

Disk /dev/sda: 21.4 GB, 21474836480 bytes
4 heads, 32 sectors/track, 327680 cylinders
Units = cylinders of 128 * 512 = 65536 bytes
Disk identifier: 0x0001edaa

   Device Boot Start End Blocks Id System
/dev/sda1 1 297546 19042928 83 Linux
/dev/sda2 297563 305176 487296 82 Linux swap / Solaris

Hi :)

The Wubi installs Ubuntu inside Windows and requires Windows systems to work and co-operate with Ubuntu. Effectively Win7 would be the parent and Ubuntu the child. This is not the route you want to go.

Please could you boot up your machine using the Ubuntu Cd as a boot Cd
https://help.ubuntu.com/community/LiveCD
and get to a command-line
https://help.ubuntu.com/community/UsingTheTerminal#Starting%20a%20Terminal
copy & paste, or type in this command

sudo fdisk -l

where " -l" is a lower-case " -L". Sudo may ask for your normal user password, not your SuperUser/Root one and it wont give any stars as you type. The output will hopefully be something like tuxar describes but will hopefully also have an ntfs partition with your Windows on it.

Note that we might need to do some tidying up to get your ubuntu onto its own space (partition) properly, so that it can be a parent too. Then we can explore about removing Win7 from your system. However, most of us keep a working Windows on a machine even if we never use it. Windows is such a pain to install that it's better to keep it dormant

Good luck and regards from
Tom :)

Hi again :)

It is worth knowing that Windows programs and malware don't affect Ubuntu at all once you have Ubuntu installed in a proper dual-boot. The first step to fixing your current system is to check that you can boot up a LiveCd session as noted in my previous post

Currently it seems that you probably have 2 installs of Ubuntu. One done properly & one inside Windows using the Wubi. I hope to help you
1. move the data from inside the Wubi onto your proper install
2. remove the wubi (or perhaps move it to its own partition outside Windows)
3. fix the mbr and booting confusions, this is "fix" as in horse racing as it is not broken
4. consider removing Win7

Good luck and regards from
Tom :)

Can you help with this problem?
