Can't boot windows 7 on a formatted 3tb harddrive. Please help....

I'm having problems booting windows 7 ultimate sp1 on a GPT formatted 3tb harddrive with an asrocks z87 mother board. "Windows cannot be installed to this drive" the os tells me, it also says that my hardware may not support the harddrive.

Does the as rocks z87 mother board really not support drives over 2tb?

  1. is it a SATA drive or IDE/adapter. Do you have the BIOS settings set to AHCI mode? the drive is internal yeah?
  2. The BIOs is set to ACHI, and the drive has a SATA cable and the drive used to be an external drive but now I've removed the case, does this make a difference?
  3. the drive is formatted? into NTFS? so the drive is recognized..but windows doesnt want to install on it? i assume the SATA power cable is connected too? truth is externals have some parts integrated in some ways, whereas traditional internal HDD's are set up the same in terms of functionality and connectivity though a standard SATA port. (this has to do with connecting data and power through the same cable and making changes accordingly). Long story short, some externals are actually laptop hard drives in a casing, this would work fine. but other externals are different and wont work at all...the shelf life on something like a 500GB or 1TB Western Digital drive will be 40-80$ but they last longer and usually have long warranties too.
  4. at this point if you want to keep trying, i would try different SATA port on the motherboard. and also i would scour my BIOS settings for some sort of compatibility/legacy mode for the HDD (though im sure youve been through the BIOS already many times). really if it has a SATA inside the casing it should work, can you upload some pics of the naked external drive? preferably with the connectors on the back showing
  5. You need to setup the Partitions on the Drive. You are missing the EFI partition.

    The use the command prompt of recovery tool of Windows 7/8 Installation DVD is described or you can press shift + F10 at the first installer screen to take you to command prompt where you can run diskpart commands.

  6. Thanks Calvin and everyone else but it's still not working even with the partitions.
    Windows says "Windows cannot be installed to this disk. The selected disk is of the GPT portion style.

    Windows cannot be installed to this disk. This computers hardware may not support booting this disk. Ensure that the disks controller is enabled in the computers bios menu.
