Is it possible to see bcd options within WinPE. I use the WinPE3 from the windows7 WAIK.
I can't find them in the registry or through wmic.

My example bcd is:


I want to use one PE image and choose its behaviour during bcd boot menu.

I am not sure what you are asking.

The BCD is a "Registry" type of file, but it is NOT part of the Registry.

Have you tried opening the BCD with rawreg:

Or are you asking something else?

I'll try to explain it by the procedure:
1. pxeboot
2. in the bcdboot menu choose one of the following options
- unattended firmware update
- start winpe
- autostart recovery application
3. start always the same boot.wim
4. after starting PE discover what menu option was used to start the image.
5. do as requested....

Do you understand my "wish" now?

So if I get it right, you are already past 1., 2. and 3.

And you presume that the chosen option in BCD is somehow "sticky" and detectable after PE has booted?

I don't think that it is "sticky".

There may be a workaround using different BOOTMGR's/BCD's and make the choice via grub4dos, with menu.lst entries that also log to a file (outside the .WIM).

One workaround I could think of:

copy \windows\system32\boot\winload.exe to \windows\system32\boot\winload_auto.exe inside the wim.
and change a bcd path to "path \windows\system32\boot\winload_auto.exe"

Not so nice but it could work. Probably need to copy the winload.mui as well then.

But I don't see how that (the chosen option) would be "visible" once booted.

With grub4dos you could use several Vista boot floppy images:
http://www.multibooters.co.uk/floppy.html
one for each "choice", then either parse the grub4dos "default" file or use either grub4dos "dd" or "write" to change/write something to any file.

jaclaz

the chain would be: PXE -> memdisk -> grub4dos -> boot.wim

how would I load the network available boot.wim from a floppy?

Why not PXE->grub4dos>(directory or disk image containing)boot.wim ?

I don't think there is a specific guide around, the most "similar" is this one AFAIK:
http://sysadminman.net/blog/2007/pxe-boot-...he-pxe-server-8

You'll have to experiment a bit, but the (pd) device should be available and so it should be the .wim in it.

Or maybe adding grub4dos and the floppy images inside the .wim?

hello ,
in windows 7 PE made by going to systen and security in control pannel
and choosing make recovery CD from the left of that dialog box.

to get network ability
type
STARTNET
on the command line
this will run the winpeini
and get wired networking started.
also microsoft menu starts in a file called winpeshl.ini
in which one line refers to it
X:\sources\recovery\recenv.exe
this CD is also got a driver store folder which is only 22MB large

you can put Bbart menu(nu2mnu) in system32 after mounting it with imagex /mountRW
and build on that using waik tools

What has this to do with the thread?
