@Karyonix
Very good, also. :loleverybody:

We must "decide" whether the appropriate "LoadOrderGroup" for each service is "Boot Bus Extender" or "System Bus Extender", compare with this:

I did a new experiment :

1) Booted the computer running the Intel cpu into Windows PE 3.0

2) mounted the VHD image located on the USB disk

3) copied the files inside the VHD image to \ of the USB disk using Total Commander

4) booted Windows 7 located on \ of the USB disk and it did not work :

BAD_SYSTEM_CONFIG_INFO

STOP: 0X00000074 (0X00000002,0X8B12FBA8,0X00000002,0XC0000003A)

I found the reason of this error : when I booted windows 7 there was the USB DVD player attached. I detached it and I booted again Windows 7 and it worked. As I said before,I think there is something wrong inside the usb file configurations.

Update: 2009.09.21
...
- If I disable IDE controller in BIOS, Windows 7 in USB disk will not be able to boot.

Important!
this can happen if disk.sys cannot connect to usbstor.

i guess generic hwid's for acpi,pci,usb?hci,usbhub are present in CriticalDeviceDatabase.
Did you also have gendisk and usbstor\disk in CriticalDeviceDatabase,
so disk.sys can attach to usb disks?

Control\CriticalDeviceDatabase\gendisk,"ClassGUID","{4D36E967-E325-11CE-BFC1-08002BE10318}"

Control\CriticalDeviceDatabase\gendisk,"Service","disk"

Control\CriticalDeviceDatabase\USBSTOR#Disk,"ClassGUID","{4D36E967-E325-11CE-BFC1-08002BE10318}"

Control\CriticalDeviceDatabase\USBSTOR#Disk,"Service","disk"

Edit:

please upload regfiles for

CurrentControlSet\Services,
CurrentControlSet\Control\Class,
CurrentControlSet\Control\CriticalDeviceDatabase,
CurrentControlSet\Control\GroupOrderList.

i will check.

@fxscrpt
I have gendisk but not USBSTOR#Disk in CriticalDeviceDatabase.
I think USBSTOR#Disk is not required.

IDE controller enabled, with IDE disk -> boot from USB success
IDE controller enabled, no IDE disk -> boot from USB success
IDE controller disabled in BIOS -> BSOD

I just pointed out what cdob said here:
http://www.911cd.net...o...=22473&st=4

The:

pci (Boot Bus Extender) - usb?hci (Boot Bus Extender) - usbhub (System Bus Extender) - usbstor (SCSI miniportSystem Bus Extender) - disk

is what he suggested,
the:

pci (Boot Bus Extender) - usb?hci (Boot Bus Extender) - usbhub (System Bus Extender) - usbstor (SCSI miniport System Bus Extender) - disk

you propose looks like nice, (and coherent with the other services) but what happens with the latter in Device Manager? B)

It makes a lot of sense if you write it down like this (where first number is "priority" in loading:
New karyonix:
1. pci (Boot Bus Extender)
1. usb?hci (Boot Bus Extender)
2. usbhub (System Bus Extender)
3. usbstor (SCSI miniport)
4. disk

It looks "better" than:
working cdob
1. pci (Boot Bus Extender)
1. usb?hci (Boot Bus Extender)
2. usbhub (System Bus Extender)
2. usbstor (System Bus Extender)
4. disk

Which looks "better" than:
original marv:
1. pci (Boot Bus Extender)
1. usb?hci (Boot Bus Extender)
1. usbhub (Boot Bus Extender)
1. usbstor (Boot Bus Extender)
4. disk

But really cannot say. :cheers:

ok...

Thank you

In your current config usbstor loads before other usb*.sys.
The order is
usbstor(tag:07)
usbuhci(tag:1f)
usbohci(tag:26)
usbehci(tag:27)
usbhub(tag:2b)

First please try 1.reg , if no success then 2.reg

2) I can't use Windows Virtual PC because I have no computers able to use the hardware virtualization

I am sorry my installation methods require special hardware. I didn't think about that.
For installation to VHD, there is another way ... by using Sun VirtualBox.
Use Disk Management or Diskpart to create VHD. Attach VHD to VirtualBox's Virtual Machine.
The rest is the same as using Windows Virtual PC.

1) if I put the SATA disk inside the USB SATA disk enclosure I will lose the warranty of my disk

There is another way.
Cloning Windows 7 from SATA disk to USB disk.
1. Get Sysinternal PsExec. Unzip PsExec.exe.
2. Create shortcut systemcmd.

@fxscrpt

your regfiles don't work because entries are restored as soon as I try to change them (I'm trying to import your files while Windows 7 is running...do you know a way to import regfiles while Windows is not active ?)

Anyway this is what happens when I attach/detach my USB DVD reader :

STOP: c000021a Fatal System Error
The Windows SubSystem system process terminated unexpectedly with a status of 0Xc0000006 (0x76d68001 0x008ef618)

or

STOP: c000021a Fatal System Error
The Session Manager Core Session failure system process terminated unexpectedly with a status of 0Xc000003a

they occurs when :

a) Windows 7 is active
b) I attach the USB DVD reader with a disk inside

instead :

BAD_SYSTEM_CONFIG_INFO
STOP: 0X00000074 (0X00000002,0X894E4BA8,0X00000002,0XC000003A)

occurs when :

a) Windows 7 is not yet started
b) I attach the USB DVD reader with a disk inside

in both cases,without a disk inside the USB DVD reader,these errors don't occur.

@Marietto2009
If you are running the USBootwatcher service, you need to edit it's .conf file:
http://www.911cd.net...showtopic=22473
with the changes fxscrpt suggested and/or with the other proposed ones.

I mean, if your .conf is all set to "Boot Bus Extender", sure you cannot change those, as they will be reset by USBootwatcher, after all it is what it was designed for. ;)

and then I imported 1.reg but problems related to the USB DVD reader aren't gone and then I tried to import 2.reg,but :

Hi,
please delete Tag value from USBSTOR key manually.

BTW: found very interesting article (Specifying Driver Load Order)

Edit:

If a boot device has child devices, those devices are enumerated. The child devices are configured and started if their drivers are also boot-start drivers. If a device's drivers are not all boot-start drivers, the PnP Manager creates a devnode for the device but does not start the device yet.

What about usbccgp/usbport?
usbccgp > "System Bus Extender" ;)

Marietto2009,
looks good. :(

c000021a is much better then 0000007b,
because the core system is up.
Csrss.exe crash 0xc000003a (STATUS_OBJECT_PATH_NOT_FOUND)
can have many reasons: hidden system partition, bad partition table, system disk not mounted, onother disk mounted as C:\ ...

please try USBSTOR > System Bus Extender.
This may have an effect on disk enumeration order.

:cheers:
Peter

Edit: Do you boot from vhd image?.
Maybe your usb disk is mounted as system disk (c:\) and vhd image as d:\ :)

STOP: c000021a Fatal System Error

The Session Manager Core Session failure system process terminated unexpectedly with a status of 0Xc000003a

they occurs when :

a) Windows 7 is active
:) I attach the USB DVD reader with a disk inside

1. When do these errors occur? When you attach and detach USB DVD drive while Windows 7 is running, does Windows crash immediately or after reboot ?
If it does not crash immediately, please check Start value of usbhub, usbstor service after you attach or detach USB DVD drive.

I don't have USB DVD drive.
2. Do you have the same problem if you attach/detach a new USB flash drive instead of DVD drive ?
3. Do you have the same problem if there is a DVD in IDE or SATA DVD drive while booting ?
4. Do you have the same problem if your VHD is in IDE/SATA disk ?

5. How about this BCD device and osdevice setting ?
Run these command from within VHD Windows.
bcdedit /copy {current} /d "whatever"
bcdedit /set {ID} device partition=C:
bcdedit /set {ID} osdevice partition=C:
Does this BCD setting have the same problem when/after you attach/detach DVD drive?

a) on computer running with AMD cpu,it crashes immediately :

FILE_SYSTEM : STOP:0X00000022

b) on computer running with INTEL cpu,it moves very slowly,it is almost frozen.

2. no

3. no

4. no

5. yes : STOP: C000021a ; status : 0x00000000 (0Xc000003a 0X00100400)

Is it possible that your USB ports can't provide enough electrical power for two drives (hard disk and DVD) at the same time ?

Today, I borrowed an external DVD drive from my workplace. It has its own power supply.
My Windows 7 RC in USB drive don't crash when I attach external DVD drive to USB port.

and then perhaps this is the reason...can you check carefully the values inside these USB configuration files and tell me how should be correct,because maybe they are not coherent with each other and I don't want that in circumstances that we don't know yet,they could be cause of errors :

usb.inf

[ControlFlags]
(; --> yes or not) BasicDriverOk=*
(; --> yes or not) ExcludeFromSelect=*

[SignatureAttributes.DRM]
(; --> yes or not) DRMLevel=1300

[StandardHub.AddReg.NT]
(; --> yes or not) HKLM,System\CurrentControlSet\Services\usbhub,BootFlags,0x00010003,4

usbstor.inf

[ControlFlags]
(; --> yes or not) ExcludeFromSelect = *
(; --> yes or not) BasicDriverOk=*

[USBSTOR.AddService]

(; --> yes or not) AddReg=DeviceSpecific

Thanks.

ExcludeFromSelect=*
This line prevent you from manually install legacy hardware from this INF. It does not affect plug and play hardware.
No problem from this line.

BasicDriverOk, DRMLevel, DeviceSpecific, BootFlags
I don't know.

In my setup, I did not modify any INF files.
Do you have any problem with original INF files from Microsoft ?

To clarify, I suggested to change usb.inf, usbport.inf and usbstor.inf for installation only.
Load the edited USB files at installation.
http://www.boot-land...?...ost&p=79325

This set boot friendly settings at current available USB drives.
Windows survive next boot. You may install to a VHD without mounting and editing the VHD file.
But there are original *.inf files still there. If you attach a new USB device,m PNP restore original *.inf settings.
Hence the need of USBBootWatcher or similar solution.

No idea about using this settings at regular windows.

Contrary editing windows source files may get nice results too.

Sorry for late answer.

This is what I did (on XP x64 host):

01] prepared usb disk for win7 boot: new partition, set partition active
02] installed win7 rtm in virtual pc
03] created new virtual box VM and booted this VM from vhd created in 2] and attached usb disk from step 1]
inside VM
04] assigned drive letter Z: to usb disk from step 1]
05] Copied Boot folder and bootmgr from boot partition > Z:
06] unassigned drive letter from boot partition (system reserved partition)
07] bootsect.exe /nt60 Z: /mbr
08] bcdedit /store Z:\Boot\BCD /copy {cureent} /d "boot from VHD"
09] bcdedit /store Z:\Boot\BCD /set {new GUID} device vhd=[Z:]\win7.vhd
10] bcdedit /store Z:\Boot\BCD /set {new GUID} osdevice vhd=[Z:]\win7.vhd
11] bcdedit /store Z:\Boot\BCD /set {new GUID} detecthal on
12] installed usbbootfix.bat (altered "goto :fix" > "goto fix")
13] shutdown VM
14] copied vhd file to usb disk.

successfully booted 3 intel and 2 amd pc's.
(with and without plextor usb dvd drive)

I don't think that usbccgp is involved:
http://msdn.microsof...y/ms801484.aspx

:)

jaclaz

you are right.
I thought in VMware there is USB hub > USB composite device > USB Hub device connection, but that's a mistake.

With the cdob solution (a little changed by me),I have no problems,but looking inside usb.inf,usbport.inf and usbstor.inf I seen settings that maybe are not coherents with each other (BasicDriverOk, DRMLevel, DeviceSpecific,BootFlags) and I would to know the reasons of these apparent incoherences.

@Marietto2009
you may try to alter only flags value in
