Installing Win7 through USB Type C

Modifying boot.wim 7

5 Modifying boot.wim

Using the command prompt as Administrator, enter

the following commands:

1. Type the following command to get the WIM index information.

Dism /Get-WimInfo /WimFile:<boot_wim_file>

NOTE: <boot_wim_file> is the path to the boot.wim (usually d:\sources\boot.wim).

An index or name value is required for most operations that specify a WIM file. Note the index number of the

windows version you are installing.

2. Create a directory to mount the windows image.

MD <mount_directory1>

EXAMPLE: MD C:\temp\bootw7

3. Mount boot.wim to the directory created in step 2.

DISM /Mount-Wim /WimFile: <boot_wim_file> /index:2 /MountDir:<mount_directo

4. Inject the downloaded USB 3.1 drivers (see USB 3.1 driver on page 4).

Dism /Image:<mount_directory1> /Add-Driver /Driver:<driver_folder> /Recurse

/forceunsigned

<driver_folder> is the location of the USB 3.1 drivers on the flash drive (see Procedure overview on page

5).

5. Unmount the boot.wim.

Dism /Unmount-Wim /MountDir:<mount_directory2> /Commit
