this is "normal" I install "windows 7" first ;). but the problem with the
wrong GPT Table Message I have also on a Raid10 with "Intel Matrix

OK you didn't answer my question about what mdadm metadata version your md
RAID is using. If it's 1.0 instead of 1.2 that could be the culprit.

The Question is, work parted correct with Raid GPT Table?

Thank you for the answer.

excuse ;).

OK.

I have 
mdadm-3.2.5-3.7.1
parted 2.4.-24.2.2

on the computer.
 

Could be a bug in parted 2.3, which is old. Try using parted 3.0.

I will search ;)

Another question is, do you really think it's a good idea to be mixing
different RAID implementations on the same physical devices, which also
appear to contain boot volumes?

My installing is, win7 on the Raid1 GPT EFI the Raid1 have Partitions, 5 for 
NTFS and one ext4 for the "/Home" Direktory

My Linux is on a SSD, SSD is also GPT EFI formated.

I think one of your RAID implementations is stepping on the GPT secondary
header. I've seen this before in a BIOS "fakeraid" implementation. So I
would look at all of your RAID implementations, make sure they're using the
latest versions.

Yes, it is a Intel Matrix Storage System, the Board is a DX58SO2 with last 
Bios & Firmware for the "fakeraid" ;)

my question is,  win can work with no Problem on the "Fakeraid" and a GPT 
Table. Could it be, that the kernel or / and parted have a Problem with the 
GPT Table on a Raid1 or a Raid10 Fakeraid ?

I have this Problem on all my three Systems (Intel), also on my Small 19" 
Intel Server.
