Can't see SSD in Windows 7 installation OR diskpart

I've seen posts from others with this problem, but I haven't found a solution. Hopefully someone here can point me in the right direction.

I have an HP Z820 Workstation. I'm attempting to install Windows 7 Pro onto a 256Gb Samsung 830 SSD. The BIOS can see the drive, but the Windows 7 install can't see anything. (It's the only drive hooked up.) So I dug around and saw it suggested that I go into diskpart, but diskpart cannot see the drive either.

I'm not sure what needs to be done. I stuck the drive in this machine (HP Z800) and did a Quick Format to NTFS. The Z800 sees the drive fine as an added device. But still nothing happening on the Z820 Windows install.

  1. It is rare but sometimes they need a quick format. Install your older drive if you have one and boot up with it and your SSD in another sata port. It should show up in Computer Management. Use the Disk Management function and do a quick format. Never do a full format on an SSD. You probably should put the older HDD in tha same port it was in previously and boot into windows. It makes a difference with some MBs.

    Then try again and windows should see the drive when you install windows.
  2. Thanks for the response. I did a quick format on the drive. Still nothing. So then I grabbed a HDD to make sure this is actually a problem with the SSD and not something more general. Turns out I can't see the HDD either. So I can't get any drives to show up for the Windows Installer. Again, they appear to be visible to the BIOS, but Windows Installer and diskpart can't see a thing. The only think diskpart can see is the thumb drive I'm using to install Windows.

    Does that turn on a light bulb for anyone?
  3. Burn the windows iso file to a disk and try an install. The win7 iso file is available for download on-line too. I downloaded a copy of win7 HP 64-Bit a while ago and burned it to a disk. You will need your own activation numbers to activate windows.

    Could be a BIOS problem. Is your sata interface set to AHCI or IDE?
