GPT partition

[Popinjay]

Thanks guys.  Managed to get it to install with Jason's info.

Having a new problem now.  The dual booted partition will not allow me to write to it when I am booted in my original OS.  The folders seem to be marked "read only", but I can't change them.  I use a script to take ownership, but that doesn't seem to fix the problem.  I can write to the other partition of the same drive just fine.

When I try to change security permissions it doesn't allow me.  It simply gives me an error saying that access is denied when trying to apply the changes.

This is a home system and I am on as administrator of course.

You never mentioned the fact you were setting up a dual-boot scenario...
Now we're gonna need more info.

What would you like to know.

The two partitions are not on the same drive.  I added the drive and wanted to add windows to it.  Windows is now on it, but I can't write to it when booted to my original OS.

Normally I am not such a total noob at this stuff.  I built my own system, and usually can solve problems on my own by looking around the net, checking out manuals etc.  But from what I can see the security options should be allowing me to write.  THe take ownership script I have doesn't seem to work.  I can't change the read-only properties of the folders in the new OS drive.

So you now have 2 HDD's...with different OS's installed...and one cannot see the other ? ?

I actually have more than 2hd in the computer, and both OSes are Windows 7, but that is essentially correct---except that the old OS can "see" the partition the new OS is on, but it can not write anything to it.  Ideally I would like both OSes to be able to access all the drives.

Update: The situation is even weirder.  It turns out I can write into specific folders that already exist, like "windows" on the partition, but not into the base of the drive "eg G"

Did the OP ever confirm he is using 64 bit Windows 7?

 In the OP it is mentioned that they created GPT Partitions.

Since 32-bit Windows cannot create GPT partitions, they must have been using 64-bit.

jason2074, excellent reference in the link above.
Thanks. Hope the OP understands the implication.
When you have two Operating Systems using the same hard drive, you can have a permission conflict .

Thanks for the info.
