install windows 7 64 bit from usb 3 stick

If you simple want to make a bootable install USB
(Without autoanswering and etc)
There's a free tool called Rufus.
You'll need the ISO of the disk - Rufus will turn your USB drive to a bootable version of said disk

david - that is not the problem
1 -i know rufus, and have used it also
2-now the question is about the diskpart method
3-i have the same with sticks made with Yumi

waiting for "to the pôint"' answers

May I ask why you even use diskpart? MS offers the so called Usb download tool , why not use it?

If you'd like to stick to your method, describe it.

What kind of computer is it?  Usually when you see that it means you have secure boot enabled.  Disable it in the Bios.

i used diskpart because its fast, and easy to use. How?  see: http://www.dell.com/support/article/be/nl/bebsdt1/SLN153364/EN?c=be&l=nl&s=bsd&cs=bebsdt1
then i copy the dvd contents to it

***note that the install starts correct - lets me choose region, and setup  - and only then asks for drivers - - - >>even whent he usb 3 stick is connected to usb 2 port
****if i do the same with an USB 2 stick -  it works

pedrag that does not solve the usb 3 stick issue here

****if i do the same with an USB 2 stick -  it works

That's new, all drives for windows installation are USB 2, and I also used diskpart to create those.

***note that the install starts correct - lets me choose region, and setup  - and only then asks for drivers - - -

That's my case that I experienced with USB 2 drives (all my install drives are USB 2) - it works in around 98-99%, only now and then some devices show the same symptoms as you described. With that percentage of success I don't blame USB drive.
No help from me how to solve it, just description that the same issue is happening with USB drives also.
Try to use that same drive on different PC to check if it works there.

you need to copy the usb3 and hard disk subsystem drivers to the USB stick and then use the F6 install drivers option.all you need are the .inf/.cat/.sys files. When you start the boot from usb the control goes from the bios to the winpe in the boot.wim. the boot.wim doesn't have the drivers.

Dism /Mount-Image /ImageFile:C:\test\images\install.wim /Name:"Windows Drive" /MountDir:C:\test\offline
Dism /Image:C:\test\offline /Add-Driver /Driver:c:\drivers /Recurse
Dism /Unmount-Image /MountDir:C:\test\offline /Commit

Select allOpen in new window

i believe dism does not work with windows 7
also - kindly suggest what drivers specifically " usb3 and hard disk subsystem drivers " is general
i already installed the usb 3 renesas driver to a folder on an usb 2 stick - and it recognised several devices - but did not continue
the usb stick is a kingstaon data traveller 16 GB USB3, model 100G3

i used diskpart because its fast, and easy to use

Clearly it's not.

I would suggest you use the other Microsoft tool intended for this - I install it on every laptop and all my desktops so this is not a problem.  If you TRULY want fast and easy, then I would suggest:
https://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool
(Direct download link: http://wudt.codeplex.com/ )

The above tool has worked for me for EVERY version of Windows Vista and later.

Lee , it is fast, easy, and works well i have used it many times with usb 2 sticks
also, the windows tool is for putting iso files on the stick, i have the DVD contents to copy on it, and when i make an iso file from it with img burner, it also does not work
i tried making the stick with Yumi also -  same story
to all - try what i say - and report back
it looks like nobody ever tried this  - and i want to understand it, and solve it if possible

To convert an USB stick to an bootable ISO you have to add the boot files. the same way that a hard drive requires a mbr that points to the boot files.

as for the dism injecting of files you can use imagex instead

imagex /mountrw WinPE.wim 1 c:\winpe_x86\mount\

Select allOpen in new window

Add the .inf file to the base image by using the peimg /inf command. For example:

peimg /inf=<path> c:\winpe_x86\mount\Windows

Select allOpen in new window

David - it does boot fine - that's no problem; and tx for pointing to the imagex
but that is only for a wim file -right? i have the dvd - and its contents copied to the usb stick, as i have shown
and adding the inf  file  -  what inf file - for what ?  the usb stick, the usb controller orr what ?

I will try it in a few hours (just to empty my USB3 flash) and do diskpart with copying files.
inf file should be for controller
:)

fine - hope to see some results

noxcho
1-yes, i have 4 sticks no problems; note that it does work ok on a usb2 stick
2-no - but i tried disabling xhci
3-that is only for iso files

Pedrag, you confirm it is not the usb stick - but something else

i found onliune that the windows start a winPE, and that does not have usb3 - or whatever drivers it needs at this point
question to solve is : what drivers ???

i have already tested it on different pc's, and with different usb3 sticks
1pc with uefi bios, other with the older bios

My guess is that integration of chipset drivers into Windows installation should solve problem, but since it is small % of devices, and I found workaround I did never test that hypothesis.

that's a possibility, but apparently nobody knows the cause, nor the solution?
i'm a bit flabbergasted by this...
and noxcho -  i reread your Q - and also you did not have a solutiuon, other than a workaround

ok guys - found the solution
i don't know if it was my fault or not, but i redid everything from the  start, on an 8 GB Sony USB 2 and also on the 16 Gb Data Traveller USB3 sticks
during this process, i noted that apparently not all files from the dvd were copied
so by recopying them  - the problem was gone

sorry to have wasted your time - apologies for that

since there was no real solution - B grade, but i did learn in the process
