    Raid 0 - 4 TB setup - Windows 7 install


    I can get all the hardware specs in a moment, I wanted to throw this question out and see if I get a quick solution.

    Don't ask me why, I have a specific purpose to my setup. I just need help installing Windows 7 - 64 bit.

    Just built a computer. I made two 2TB harddrives Raid 0 (don't ask). When I go into windows I get errors from "can't install windows here." Is there something simple I am overlooking?

    Unless you have a new EFI based motherboard, I don't think you can boot from a drive greater than 2TB in size.

    Hi abelltx and welcome to W7 Forums

    W7 cannot install on a disk that is greater than 2TB in capacity, unless such disks are set up as EFI. A BIOS based system does not support EFI.

    ASUS M5A97 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS

    HGST Deskstar H3IK20003272SP (0S02861) 2TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive x2

    I just checked and I do have EFI...

    I guess what I am confused now is diskpart, I have never seen it before. How should I setup the partitions for 4TB?

    Real fast. I don't care to have a 4TB partition, if I could just create a boot partition of 500 GBs and then have 3.5TB to work with on a RAID 0. I would be happy.

    Okay, so I think I got everything figured out. But now when Windows install has a restart it just sits there blinking with a white cursor.

    Drives (or RAID arrays) larger than 2GB have to be set up as GPT. A GPT drive (or array) can only boot Windows 7 if the PC uses EFI rather than a traditional BIOS.

    (I'm not sure this is the best advice if you need custom partitions, but it may help.)

    Do you need to install RAID drivers during the Windows installation? (Not a rhetorical question.)
