Have you tried delete it instead of format already?

And yes, when you delete it, it will still show for you to select.

Windows setup will recreate and format it without you seeing it formatting.

Good luck

Thats a valid ISO(if you dont know that) been here for a month now, and yes been install by lots of users.
i guess your not among scene/torrent community.

Your guess is 100% correct -- I'm totally new at all this scene/torrenting stuff.
AND, I've never heard of, nor seen that particular iso on SevenForums.

Since this is a valid iso, used by the community with total success, the problem then seems to lie with your attempted installation.

Your photo shows 3 HDDs.
You said you formatted the drive with Vista on it.
The picture indicates that Disk_1, partition_2 was formatted as Primary, 48 GB.

The error message says "Setup was unable to use the existing system partition because it does contain the required free space."

I would interpret that as meaning:
In order to install Win 7 anywhere, Setup has to copy files from the iso
to begin the installation process.
My experience with all installs, is that he copies those files to (normally) C:\, the "System" drive.

Your "System" partition indicates only 5 MB free -- that's your "Disk_1 Partition_1:Lost".

So, I would guess that is what the problem is:
Insufficient space available on "Disk_1 Partition_1:Lost", for Setup to copy the installation files....

But, with a Total size of 109 MB, it looks like that won't happen.

i feared that but i didnt face this problem with Vista!
so the solution would be to add same 8Gigs to that drive enabling setup to save instillation files on it, but can i invert back the size hence will i need those files again.

i tried to merge those two drives but i get these error.

That's probably because you last had XP..
I never did Vista, but I think he's the reason for that weird 109 MB System partition.

I would think so, but the 109 MB is "special", giving you the new error message, on the Merge attempts.
AND, I think it's gonna have to be more than 8 GB..

but can i invert back the size hence will i need those files again.

I have absolutely NO Vista experience, and can't even venture an opinion on that.
Best that I drop off, and leave it to the forum's Vista gurus.
Good luck, I'm sure its "do-able", but needs a careful sequence-of-events to be followed.

that weird partition used to have XP on it and then i split it to 2 partitions and installed vista on 2nd before removing XP and resizing its partition. so basically that drive was primary hence system partition.
