gparted can't see ntfs partitions of new win7 install

hi,

so i installed win7 ultimate on a 2TB HD and was hoping to dual-boot it with meerkat, i did a standard install and shrunk the partition using win7 disk management to leave 500GB for ubuntu.

problem is ubuntu can't detect the existing win7 install, when selecting advanced setup it just shows one big unallocated partition.

i went back into win7 and extended the partition again, then booted into ubuntu live cd to see if maybe gparted would do the trick. gparted also cannot detect the existing win7 install and just displays unallocated 1.82TB.

in terminal if i do 'sudo parted /dev/sda print' i get this message:

Warning: /dev/sda contains GPT signatures, indicating that it has a GPT table.
However, it does not have a valid fake msdos partition table, as it should.
Perhaps it was corrupted -- possibly by a program that doesn't understand GPT
partition tables. Or perhaps you deleted the GPT table, and are now using an
msdos partition table. Is this a GPT partition table?
Yes/No? ^C

wasn't sure what to write there so i just breaked out of it.

anyone experienced this before?

thanks.

Is this on a MAC? It seems you have a GPT setup rather than the normal MBR. This is likely to be your problem with Gparted.
I don't have a link I'm afraid, but if you do a search for GPT or GUID Partition Table you will surely come across posts by srs5694. He has helped several people in your situation. That's the best I can do for you, but somebody else may be more able than me to advise you.
