I am trying to install Ubuntu 10.04 as a second OS on a laptop that has Windows 7. In Windows, I have created the below partitions:
C: -> NTFS - 225GB (Windows installation) D: -> recovery partition F: -> NTFS - 175GB User Data G: -> NTFS - 50GB This is where I want to install Ubuntu on.
In the Ubuntu Install/Setup process (using a 10.04 live CD) , the last partition (on G:) is not shown separately, but seems to be grouped together with the other NTFS partition. I therefore can't choose the 50GB partition as the Linux installation root.
I tried leaving the partition as unallocated space (unformatted without any file system written on it) but Ubuntu still did not recognize it during installation.
How can I format this 50GB partition in Windows (either using Windows Disk Manager or some other disk partitioning tool) so that Ubuntu setup can see this partition as a distinct one and allow me to install Linux on it?
Can formatting this 50GB partition as ext2/3/4 help? If yes, what tool on Windows can allow me to do that?
What other solutions do I have to install Ubuntu, whilst maintaining my Windows 7 partitions?
I read online that there is a limitation that hard drives can have 3 partitions and 1 extended partition. The extented partition cannot have any OS (bootable) so you can't use that for Linux. How can I make one of the existing partitions extended? My thoughts are I could try making one of the NTFS partitions (only used for data storage, no OS) extended, then be able to use the 50GB partition for Linux.
