T470 with Windows 7?

We just received our first T470 laptop and it came with Nvme drive THNSF5256GPUK. I'm having a hard time install windows 7 on it. I'm able to create a bootable windows 7 with Usb 3.0 drives but when I go to select hard drive, there is no hard drive listed there. Anyone else had this issue? Were you able to sucessfully install windows 7 on T470? I did install the KB2990941 to the boot.wim and install.wim.


Thank you

Re: T470 with Windows 7?

Try this, boot up to the Windows Installation USB, and then at the welcome screen  press Shift + F10 and it should open a command window.

 

  • In the command window type:   diskpart
  • At the DISKPART> prompt, type:  list disk

 

You should get a display showing the available disks, most likely the SSD will be Disk 0 if the only drive install, but if not note the Disk number of the SSD and replace the x in the command with that number.

 

  • Type: select disk x     which should return "Disk x is now the selected disk"
  • Type: clean

 

Close the command window and proceed with the installation and see if it will complete normally.

 

Good Luck,

I followed the instructions on MSFT website (see Method 1):  https://support.microsoft.com/en-us/help/2990941/update-to-add-native-driver-support-in-nvm-express-...

 

Then I booted the ISO on ThinkPad T470 with Toshiba NVMe SSD.  There was no problem to install Win7 on that drive.

Re: T470 with Windows 7?

Did you have to insert Toshiba drivers or any intel rapid storage driver to the iso? I assume you burnt the iso to a dvd?

No, you don't need any Toshiba driver.  The MSFT hotfix is good enough, for any NVMe SSD.

You don't need any Intel rapid storage driver either.  That driver is only for SATA SSD, not for NVMe SSD.

I "burnt" the ISO I created to USB key using UltraISO.  But in the past I also burnt it to physical DVD and that works as well.

I burnt the dvd after following the instructions and when load from dvd and click on install now, I get an error A required CD/Dvd drive device driver is missing.....? I'm using a usb dvd drive to install this. Did you use Legacy mode or UEFI?

Re: T470 with Windows 7?

I have done both legacy and UEFI, but how did you build the ISO?  Step 10 from the MSFT document describes 2 different ways to build the ISO depending on legacy vs UEFI.  Do you intend to deploy Win7 in legacy mode or UEFI mode?  What are your BIOS settings on the Startup screen of BIOS Setup?

 

UEFI/Legacy Boot

UEFI/Legacy Boot Priority

CSM Support

Re: T470 with Windows 7?

In step 10 from MSFT I choose Legacy version of the ISO and burnt it to a dvd.

In Bios I have 

 

UEFI/Legacy Boot set to [Legacy Only]

- CSM Support set to [Yes]


What do you have your bios set to and which ISO did you use?

Re: T470 with Windows 7?

I have built both ISOs and tested all the different BIOS settings.  Why don't you try using my ISO?

EDIT:  removed link

 

(let me know as soon as you finish downloading that, so I can remove the link)

Re: T470 with Windows 7?

Thank you so much for this! Is this Legacy ISO? Also is this win7pro? If so, would you mind sharing the UEFI version as well.
