win 7 external boot bsod

[zug134zwang]

Apologies if this is the wrong subforum, or if this question has already been answered.

I recently created a bootable Windows 7 installation flashdrive and used it to successfully install Windows 7 on my internal hard disk. Subsequently, I swapped out the Windows 7 hard disk for an internal Fedora hard disk, moving the Windows 7 hard disk to an external usb docking station. When I try to boot the [docking station : Windows 7] hard disk via the F12 key, Windows starts, then a bsod flashes, then the screen goes dark.

I know the Win 7 hard disk is good because when it was internally connected I occassionally booted with it. I know the docking station is good because I have just used it to boot a Fedora 26 hard disk, via the F12 key.

I request help getting the Windows 7 hard disk to boot from the docking station.

Shown below is
1. My hardware
2. The procedure that I followed to create the installation flashdrive and then install Windows 7 to an internal hard disk.
3. My motivation

1. My hardware

    os         :  64 bit fedora 26 and 64 bit Windows 7 professional
               :  explained in the (3. My motivation) section
    cpu        :  Intel I5-4440 Processor BX80646I54440
    mobo       :  (64 bit) Gigabyte H97 SATA Express M.2 SSD UEFI DualBIOS DDR3
                  1600 LGA
    memory     :  32 gb : 2 x [G.Skill F3-1600C10D-16GAO Ares 16GB (2x8GB)
                               DDR3-1600Mhz Memory RAM]
    psu        :  corsair cx series 600 watt
    hdisk      :  1tb internal western digital wd10ezex sata
    video card :  none - I use mobo's onboard video at 1920x1080.

2. The procedure

a.  I placed my Fedora 26 hard disk in the external usb docking station and
    booted it via the F12 key.

    b.  Within Fedora 26 I configured the flashdrive:
        (1) I obtained a Windows 7 iso
        (2) I inserted a flashdrive into /dev/sdd
        (3) In bash, I executed :
            woeusb --device Windows_7_64-bit_Professional_x64.iso /dev/sdd

    b.  Within Fedora 26 I pre-configured the internal hard disk:
        (1) I verified that the hard drive was recognized as /dev/sdd (unmounted).
        (2) In bash, I used the parted command:
            mklabel msdos
            mkpart primary ntfs 1MiB 100%

    c.  I removed the (externally docked) Fedora 26 hard disk and used the F12
        key to boot with the flashdrive.  I then used the flashdrive to install
        Windows 7 to the internal hard disk.

    d.  I then removed the flashdrive and booted into Windows 7 via the external
        hard disk.  I have been using Windows 7 successfully about once a week.

3. My motivation

    Prolonged use of Fedora 26 (daily) via a docking station may make my Fedora
    hard disk go bad.  Instead, I want the Fedora 26 hard disk to be internal
    and use the docking station for the occasional Windows 7 boot.

Win7 doesn't boot natively from an external drive. A few registry changes are required.

Load the system hive for Controlset000 and Controlset001 and set PollBootPartitionTimeout to 30000 and
BootDriverFlags to 6

wow, thanks. if this works, you will have saved me a lot of trouble.

Load the system hive and give it name , e.g. SYS

Then try merging this reg file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYS]

[HKEY_LOCAL_MACHINE\SYS\ControlSet001]

[HKEY_LOCAL_MACHINE\SYS\ControlSet001\Control]
"BootDriverFlags"=dword:00000006

[HKEY_LOCAL_MACHINE\SYS\ControlSet001\Control\PnP]
"PollBootPartitionTimeout"=dword:00007530

[HKEY_LOCAL_MACHINE\SYS\ControlSet002]

[HKEY_LOCAL_MACHINE\SYS\ControlSet002\Control]
"BootDriverFlags"=dword:00000006

[HKEY_LOCAL_MACHINE\SYS\ControlSet002\Control\PnP]
"PollBootPartitionTimeout"=dword:00007530

Again thanks. On Sunday, I will temporarily swap the Windows hard disk back in, to make the registry changes. I am a programmer and I was planning on : 1) backing up the existing registry and 2) then editing the registry directly.

Based on your 2nd post, I will merge instead.

You will need to use usb3.0/3.1 connection. USB 2 is much too slow. So you also need to have the USB 3.0/3.1 drivers installed in win 7.

I assume you are using USB 3.0/3.1 ?

 

[zug134zwang]

i wasn't going to use usb 3, but i will now.

 

[SIW2]

USB 3 drivers will need to be installed.

dism++ should be able to install drivers to an offline OS.
Dism++ x86/x64
