Hello,

I am trying to install ubuntu 11.04 on my dell laptop (N5010).
I have the following partitions:

1) OEM (39 MB)
2) System (100 MB)
3) C (windows intallation) (100 GB)
4) D (150 GB)
5) E (~220 GB)

I shrank my C drive 10 GBs to make space for ubuntu but during installation of ubuntu it shows only the first 3 partitions (OEM, system, C (reduced)) and all the rest as one chunk of unusable hard disk space).
In windows I can see this chunk as three distinct partitions.
Please Help.

Welcome to the forums.

Did you create these partitions in Windows? Windows does not use the standard extended partition for extra partition but converts to a proprietary LVM - logical volume manager.

Dynamic volume is a Microsoft proprietary format developed together with Veritas (now acquired by Symantec) for logical volumes.

Post a screen shot from windows to see if partitions are still basic or converted to dynamic. Per windows it is a one way conversion and the only way to unconvert is to back up entire drive and repartition. Some third party tools may do it without losing data, but I would still have backups if you want to try that.
