Problem trying to add Windows 7 Pro on a 256GB SSD with Windows 8.1 preinstalled RRS feed

  • Question

  • I shrunk the SSD down leaving about 100 GB for Win 8.1 and formatted the remaining space creating an NTFS partition for the Windows 7 (DVD) install. I disabled quick boot and changed the boot order so the optical drive is first. When I attempt to boot from the disk, it freezes before i get to the screen to choose which partition to install to.

    So i then changed the bios from UEFI to CSM, and now i make it as far as the screen to choose the partition, but it won't let me install on the newly created SSD partition, with the message: "windows cannot be installed to this disk. The selected disk is of the GPT partition style", greying out the install button when trying to select this partition. However, when I select one of the 1.5 TB HD's, the install button becomes active. But I really want to install Windows 7 on the SSD.

    My machine is a Toshiba Qosmio X70 with 32GB ram, two 1.5 TB HD's and a 256 GB SSD

  • Hi,

    For the issue,please let us know your Windows 7 version.64bit or 32bit?

    Booting from GPT is only supported for 64 bit editions of Windows 7 on UEFI based systems.

  • My suggestion:  Clear the whole thing and just install Windows 7 on it.

    If you feel you really might want to get back to 8.1, do a System Image backup to an external USB drive that you can potentially restore at a later time.

    Trying to dual boot two different versions of Windows is fraught with peril.  It can be managed but you really need to know what you're doing.  It's better to choose one operating system and just optimize it to do all you need to do.

  • While running Windows 8.1, go into Disk Management and delete that partition, create a new partition, format it NTFS, then reboot to install Windows 7 on that partition.

    What I need is a reply from someone who knows what they're talking about. Not someone telling me to just "clear the whole thing". If I was willing to do that, I wouldn't have bothered making the post. As I already indicated, I was able to install Win7 on the HDD, which is not what I want to do. For starters, learn how to read before you try to "help" someone in the future.

    That's what I did originally. That partition WAS created in Windows 8.1.

  • Charming.

    You may not be "willing", but you may find it "necessary". 

    Here's another suggestion you may find irritating, but also based on experience:  Perhaps you could consider installing a virtualization system, such as VMware (or even use Windows 8's HyperVisor), and install your Windows 7 system as a virtual machine that you can run concurrently with Windows 8.1.

    I wish you the best of luck.

  • No, the loss of speed and performance due to virtualization defeats the purpose of wanting to use the SSD in the first place. I might as well just install the Windows 7 on a hard drive. But if I'm willing to do that, why did I spend an extra $300 or so on a machine with 256 MB of SSD.

    I've actually received some good suggestions from people in another forum.

  • Have you solved your problem? In positive case could you tell me how please? I cannot install any VM over win 8. I' use the PATRAN and ABAQUS and I can't update them for newer versions every year!! Thank you very much by your reply...
