I want to install Ubuntu 12.10 64 bit alongside Windows 8, so I created some free space in Windows 8.

When I try to install Ubuntu using a Live USB, the free space created is not visible and the partitions shown are completely different.

But when I click the option "Try Ubuntu", I am able to use my Windows partitions.

@Takkat Does free space belong to dynamic disk?If so, what is the solution for this? –  sabarish Jan 24 at 13:10

@Takkat Ya. You were right. Dynamic disks were the problem.I installed AOMEI Partition manager to change disks to basic.Then the problem solved.If anyone has a similar problem,install AOMEI partition manager and change.Thank you for your valuable comments –  sabarish Jan 26 at 14:07

Ubuntu does not support Windows-specific "dynamic" disks. This may be one reason for partitions not showing up on installing Ubuntu or when partitioning a drive from Ubuntu.

Before we partition a drive on Ubuntu we therefore have to change the partitions type from "dynamic" to "basic".

Obviously this can only be done from Windows (see Window Server Support and Microsoft Technet), e.g. with a partitioning tool (e.g. AOMEI Partition Assistant).
