Linux not seeing partitions

I currently have windows 7 install on my 256 SSD (partitioned into two 128)

when i go to install linux, I have tried ubuntu and mint linux now and it won't show my partitions just shows the whole drive as free space.

any help would be great.

Hmm, it might be an issue with Ubuntu taking their own route as usual and replaced a perfectly capable partitioning software (GParted) with their own.

You could check how the partitioning looks like in GParted live CD.

It could be a bug with the installer; I haven't used Ubuntu or a graphical installer in years so I'm not sure.

How about if you bring up a terminal and post the output of this:

$ fdisk -l

Right so this error comes from two things left over raid data or left over GTP data (data left over from when a drive is coverted back from a dyamic drive to a basic) this was my error.

First to find your partitions

sudo fdisk -l

thats a lower case L

For me it was /sda but it could be /sdb

*if you havent used raid skip this one*

So to clear raid data you need to use dmraid.

sudo dmraid -E -r /dev/sda

/dev/sda is the drive you cant see partitions of.

For left over gtp you use gdisk to clean out the data.

sudo sgdisk --zap /dev/sda

If you get an error use

sudo apt-get install gdisk

And run command again if you get am error just ignore it.

After the installer should be about to see all your partitions. Hope this helps anyone looking for it later on.
