Thanks roktnji
Alsp the links in your post are great.

Okay,

In Gparted there was an exclamation mark over /dev/sda2 and it wouldn't resize.

When I ran ntfsresize the first time it gave me a series of errors.

That was when I posted here.

I ran ntfsresize again and this time I got an error message which said "run chkdsk /f".

So I booted into Windows 7, agreed to the EULA and generally set up as Windows required me to do before it would proceed.

After that I ran chkdsk /f, restarted and booted with my livecd.

This time I WAS able to resize sda2, expand the logical partition and set up partitions prior to my linux installation.

Am currently installing!

Will report back on whether I can use Windows 7 as well.

Well, Windows booted up but no sign of Grub, so I can't access the new installation.

I'm going to have to chroot into it and try to fix it.

You marked thread as solved, can you post the solution for others who may have the same problem?

Sorry, Eddy, I thought I had.

Basically Gparted and ntfsresize wouldn't work because the partition was flagged (by Windows, I guess) as requiring chkdsk /f to be run.

Gparted just had an exclamation mark next to the partition and simply refused to resize.

However, when I ran ntfsresize a second time, it suggested that I run chkdsk /f from Windows.

Once I ran that, then the exclamation mark was no longer on the partition in Gparted and I was able to resize it.
