[standalone OSD2 boot up in PXE is failed]

Hello,

I'm working on deploy PXE to my lab enviroment, I'm using pxelinux as PXE server, and TFTPD.exe as TFTP service in a Windows2008 server. The server installed AIK for win7 as well.

I have two OSD2 images which is ISO format, image A is 153MB, image B is 3.99GB.

Since OSD2 is using WINPE v2, the boot up process is different with WINPE v1, so I'm using following script to translate the ISO image to WIM:

Step1, decompress the ISO to folder "winpe_x86", then mount the WIM file in winpe_x86\SOURCES folder:

"C:\Program Files\Windows AIK\Tools\x86\imagex.exe" /mountrw C:\winpe_x86\SOURCES\BOOT.WIM 1 c:\winpe_x86\mount
xcopy /s /y c:\winpe_x86\SMS\DATA c:\winpe_x86\mount\SMS\Data\
xcopy /s /y c:\winpe_x86\SMS\PKG c:\winpe_x86\mount\SMS\PKG\

Note the last line, it's copy PKG folder to mounted SMS folder since image B is a standalone image, all software is stored in SMS\PKG.

Step2, commit image and unmount it:

"C:\Program Files\Windows AIK\Tools\x86\imagex.exe" /commit c:\winpe_x86\mount
copy c:\winpe_x86\mount\Windows\Boot\PXE\pxeboot.n12  C:\PXEServer\TFTPRoot\boot\
copy c:\winpe_x86\mount\Windows\Boot\PXE\pxeboot.n12  C:\PXEServer\TFTPRoot\boot\
"C:\Program Files\Windows AIK\Tools\x86\imagex.exe" /unmount c:\winpe_x86\mount
copy c:\winpe_x86\boot\boot.sdi C:\PXEServer\TFTPRoot\boot
REM copy c:\winpe_x86\Sources\BOOT.WIM C:\PXEServer\TFTPRoot\boot\winpe_x86.wim

Step3, edit BCD file:

set BCD-File=c:\PXEServer\Tftproot\Boot\BCD 
del %BCD-File%
Bcdedit /createstore %BCD-File%
Bcdedit /store %BCD-File% /create {ramdiskoptions} /d "Ramdisk options" 
Bcdedit /store %BCD-File% /set {ramdiskoptions} ramdisksdidevice  boot
Bcdedit /store %BCD-File% /set {ramdiskoptions} ramdisksdipath  \boot\boot.sdi
for /f "tokens=1-3" %%a in ('Bcdedit /store %BCD-File% /create /d "WinPE x86" /application osloader') do set guid1=%%c
Bcdedit /store %BCD-File% /set %guid1% systemroot \Windows
Bcdedit /store %BCD-File% /set %guid1% detecthal Yes
Bcdedit /store %BCD-File% /set %guid1% winpe Yes
Bcdedit /store %BCD-File% /set %guid1% osdevice ramdisk=[boot]\Boot\winpe_x86.wim,{ramdiskoptions}
Bcdedit /store %BCD-File% /set %guid1% device ramdisk=[boot]\Boot\winpe_x86.wim,{ramdiskoptions}

Bcdedit /store %BCD-File% /create {bootmgr} /d "Windows Vista BootManager"  
Bcdedit /store %BCD-File% /set {bootmgr} timeout 30 
Bcdedit /store %BCD-File% /set {bootmgr} displayorder %guid1%
Bcdedit /store %BCD-File% /enum all
pause

According to the process above, ISO file is translated to WIM, the WIM of image A is around 147MB, it's can boot up and work fine, the WIM of image B is 3.24GB, it's cannot be booted up and show the error ( see attachment ).

I also did a testing, image B is worked if I just copied few file to SMS\PKG folder, looks like 2GB or 1GB WIM can be booted up via PXE, but it's not support 3 or 4GB.

Does anyone have any idea about this issue? Do I have another choice if PXE really can not support big image file?

Thanks in advance!

[Hello MSFN!]

I'm glad to join this forum, I'm working on a PXE project and facing some issue during deploy images, I found this forum when I tried google something, it's really a technical board, I learn a lot of knowledge from MSFN. I'll post something to this forum to discuss with you guys, hopefully we could exchange skill in MSFN!
