I bought a Toshiba laptop with two partitions: C: with Windows 7 and D: with my data. I want Ubuntu 12.04 be installed in D: but when I try the computer shows me C: divided in two parts. If I choose Something else and select /dev/sda3 a message appears: There is not a root file system. What can I do?

Follow the steps




  • Take backup every thing in D: drive. Because all data will be lost.

  • Boot with live usb

  • There will be screen asking for install options like install along with windows 7,install ubuntu as only OS etc. Choose Do something else option at the end.


  • Now partition tool will open. Delete the disk you want to install ubuntu to. You can see the unallocated space. Select that and then click on Add.


  • Now we will add SWAP partition. Give disk space value as 1024MB (1GB) or 2GB. If you have good amount of RAM (~2GB), 1GB swap space is enough. Select SWAP in file system dropdown.Press "OK".

  • Now again continue previous step for the rest free space (or whatever size you want for ubuntu installation). This time select filesytem as ext4 and mount point as /.

  • Check in partition tool window, grub installation location is same as your hard disk not your usb disk. (most likely bootloader location -> in sda ...)

  • Now go ahead and installation will finish in minutes.



Note: Don't enable downloading of 3rd party apps and update in previous screen. Better don't connect to internet while installing.Good luck. Let us know how it went.
