install ubuntu 12.04 with UEFI and windows 7 64 bit , getting message /dev/sda contains GPT signature

install ubuntu 12.04 with UEFI and windows 7 64 bit , getting message /dev/sda contains GPT signature

I have 2 options in bios Lagacy support (enable/dissable) . Its a recently purchased laptop and has UEFI option .
I enabled Lagacy support and installed windows7 64 bit successfully . Then if i try to boot Ubuntu 12.04 ( 32 bit) from USB and in live os i tried to install . When i tried it says /dev/sda contains GPT signature no fake msdos partion detected and if i select yes/No both are not showing the already existing partions.
So what i did is i tried linux mint latest version (64-bit , i guess there is not much difference because both are based on Debian / linux partions ) . And even in this 64 bit i get the same problem
Then i fromated the disk in live linux and linux installed successfully.
Now when i tried to install windows 7 (64 - bit) it gives error like windows cannot install since it do not have GPT partion .
please help me thanks in advance . I need dual boot windows 7 (64 bit because i have drivers only for it ) and ubunut or linux mint also (eaither 64 or 32 bit is ok )
