ok i can now succesfully boot up into windows 10

kernel nfs://${fog-ip}:/images/os/mswindows/wimboot
initrd nfs://${fog-ip}:/images/os/mswindows/10-21h1/boot/bcd bcd
initrd nfs://${fog-ip}:/images/os/mswindows/10-21h1/boot/boot.sdi boot.sdi
initrd nfs://${fog-ip}:/images/os/mswindows/10-21h1/sources/boot.wim boot.wim
boot

but now its says i have no device drivers, i guess i have to slip stream them in here

/images/os/mswindows/10-21h1/

is that right?

thanks,
rob

This WILL boot the windows iso image into memory. The problem as I mentioned before is that this installer expects/demands the install files be on a local drive (dvd/usb) and not dispatched over the network. That is why in my tutorial I tell the reader to install the files on a CIFS file share then create their own winpe image to boot up to the network then connect to the CIFS share and run the windows setup program from there. That way you can install over the network using a network file share.

@george1421 can I alter the boot.wim from the existing windows 10 installation file or do I have to do it via winpe boot.wim file

I can’t answer that. I’ve never used the default microsoft one. I’ve always created a custom winpe image. That way in the batch file I use to do the winpeinit I can mount the CIFS share as Z:. Change to Z: and run the winsetup.exe program.

But again I don’t go about installing windows 10 from dvd any more. I use MDT to create the golden image and then use FOG to deploy the golden image. There are valid use cases for doing it the way you proposed, so it not wrong. We’ve just decided to take a different approach. FWIW, you can pxe boot into MDT too using the same process as you have here, since it is a winpe image.

@george1421

the wimboot is the latest one of there website
and at the bottom ive added the ISO

but when it start up it doesnt initialize the windows installer

i did add the net use command and point it to my cifs share where the windows install dvd is but it looks like its deleted those lines

i can run the command manually but i get permission denied

am i doing something wrong ?

thanks,
rob

There is version 2.7 but I noticed that its not posted as the main one. https://github.com/ipxe/wimboot/blob/master/wimboot

and at the bottom ive added the ISO

The ISO doesn’t matter its not used and just taking up RAM.

i did add the net use command and point it to my cifs share where the windows install dvd is but it looks like its deleted those lines

This is from my secret sauce cookbook

i can run the command manually but i get permission denied

This is an interesting one. Maybe doe the file exist? I wonder if this system is hosted on SAMBA it needs the linux execute permissions set? Or is WinPE stopping you from executing random programs? I can only guess here.

@george1421 so if i dont need the ISO what lines do i add in the menu, just the WinPE lines?

set tftp-path tftp://${fog-ip}
set pe-path ${tftp-path}/os/winpe
kernel ${tftp-path}/wimboot gui
imgfetch --name BCD ${pe-path}/BCD BCD
imgfetch --name boot.sdi ${pe-path}/boot.sdi boot.sdi
imgfetch --name boot.wim ${pe-path}/boot.wim boot.wim
boot || goto MENU

as atm for my windows 21h1 menu i have appended the iso line to it ie

initrd nfs://${fog-ip}:/images/os/mswindows/10-21h1/WinPE_amd64.iso

Yes this is all you need to boot the winpe image. Your winpe complete environment is in the boot.wim virtual hard drive. If you look on the iso that same boot.wim file is on the iso image.

[robertkwild]

@george1421 lol OK I’m being a donut

So I take that new boot wim from the winpe iso and put it in the same place Ie overwrite my normal boot wim in my windows 10 dvd folder that I have saved in the smb share?

[robertkwild]

@george1421 thank you so much george, if i could see you i would buy you a beer mate!!!

set tftp-path tftp://${fog-ip}
set pe-path ${tftp-path}/os/winpe
kernel ${tftp-path}/wimboot gui
imgfetch --name BCD ${pe-path}/BCD BCD
imgfetch --name boot.sdi ${pe-path}/boot.sdi boot.sdi
imgfetch --name boot.wim tftp://${fog-ip}/os/mswindows/boot.wim boot.wim
boot || goto MENU

basically i made the winpe, mounted it, slipstreamed the drivers, edited the startnet.cmd, unmounted it and comitted

in

C:\WinPE_amd64\media\sources\boot.wim

i copied it over to the above and now it all works lovely

again, thank you so much george!!!

[robertkwild]

dont think my cifs share can handle the setup over the network as it gets stuck sometimes after mounting the smb share where my windows 10 install is

after this it should pop up with the setup.exe, sometimes it works, sometimes it doesnt, so im pretty sure my smb share cant handle it

[robertkwild]

@robertkwild scrap this it works and when it runs the setup eventually its quick like a normal install
