---- This has worked with Beta2 so far : ---
First here a reference:
One needs the file USBSTOR.SYS, which only final driver installation of the
USB of drive assembly inclusive after complete installation is in System32 \
DRIVERS \.
No notion where the file before is. I it to me from a finished installation
pulled.
Beyond that the external non removable disk must be selectable in the BIOS
also as boat drive assembly.
One has this file is now some preparations to be met. First must Vista the
installation image on a DVD be burned.
An installation from a current Windows is not possibly written functioned,
there the installation files on the wrong non removable disk and also the
MBR (master boat record) on the wrong non removable disk is changed.
After now the DVD blank is burned, one can again start the system now (with
the installation DVD in the drive assembly).
IMPORTANTLY: The external non removable disk must be adjusted now as the
first boat non removable disk in the BIOS before the installation, otherwise
the MBR is written on the wrong non removable disk.
Now the installation can loose-go. Up to the first restart of the
installation everything runs according to used kind.
Keys enter, plate select, format and starting from the post office.
Now the special comes.
After the restart first times the old Windows must be started now (in the
BIOS boat sequence to change).
Copy the file USBSTOR.SYS on the Vista non removable disk after windows \
system32 in the old Windows now \ DRIVERS.
Now the Registry editor open, click on HKEY_LOCALE_MACHINE and select then
in file the menu "structure shop. ".
In the following go to file dialogue on the Windows Vista non removable
disk and you find config under windows \ system32 \ the file "SYSTEM
"without any file dung.
This öffen. In the following input windows the whole one any name give (for
the sake of simplicity I recommend "VISTAUSB ") and' S. continues to go.
In this new structure tree (you through click on "+ the "symbol open)
finds your ControlSet001, ControlSet002 and further things, which are not
important here.
In the guidance it is located that one must make the changes only at one of
the two trees (the active one, which in all rule the ControlSet001 is).
Since I do not trust the whole, I recommend to make the changes at both
trees.
Thus. Now we open the tree ControlSet001 and the tree contained in it "for
services ".
Now have you a quite long list before you. Scrollt now downward, until your
USB finds. Here now some values must be changed, so that the USB driver is
in former times loaded, so that that becomes possible boats of the USB non
removable disk.
The following changes must be made: DWORD "start "the value "3 "in "0
"change STRINGER "Group "the value "cousin "into the value "system Reserved
"change.
With the following keys: - usbccgp - usbehci - usbhub - usbohci -
usbuhci
In the C' t stands that it gives in the Registry either usbohci or usbuhci.
With me both keys were nevertheless represented. With the key "USBSTOR
"must be changed also the DWORD "for start "of "3 "on "0 "and the stringer
"Group "with the value "system Reserved "must again be put on.
All changes made you (with ControlSet001 and ControlSet002), you click on
the structure "VISTAUSB "or however your that called and in file the menu on
"structure removing. ".
IMPORTANTLY: With do not right-click on the structure and then deletion. If
you that makes, can you the installation from the front begin.
Since changed the attitudes now and also copied the file, can you the
computer again start now (and in the BIOS the boat sequence again to the USB
plate changing), and the installation to continue, up to the next restart.
With the automatic driver recognition and installation almost all changes of
Windows are made again retrogressive (however no fear, only this one times).
Thus the whole procedure again, weils was so beautiful with the boat drive
assembly changes and then in the Registry work, as described above.
Afterwards the remainder of the installation problem-free runs off and it
can you make happy, now an boat-able Windows Vista on an external USB non
removable disk have.
