You'll need to find out what drive letter the CD drive has. You can hard code a drive letter into your code like that ONLY when you can be relatively certain that it will be correct every time.

You can get a cmd at that screen with Shift+F10. Then you can find out what your CD drive is, and what is D: and/or if a D:\install.wim actually exists.

Or you can use imagex /apply and place the contents of install.wim onto c: drive.

Place imagex and other necessary files and install.wim on D-drive, then use imagex /apply to extract and write the contents of install.wim onto C-drive.

Then, you can use BCDBOOT command-

Bcdboot.exe <source> [/l <locale> ] [/s <volume-letter> ] [/v]

<source> is windows source folder

/l <locale> is locale (such as en-us)

/s <volume-letter> is the target drive

/v is verbose mode

So you should issue-

bcdboot C:\windows\ /l en-us /s C: /v

to create a bcdstore on C drive (based on windows source files extracted from install.wim onto c-drive). Make sure c drive is the active partition, and boot the system, and it should start windows setup.
