Hi Ian,
I changed the bcd file. But I see exact same behavior. After loading all files 
I see the windows "Loading files" scroolbar and then a blank screen.
Thanks
Amit

Ok, so what we know so far is the boot process has done this in terms of 
execution flow:


Power On -> BIOS -> iPXE -> wimboot -> bootmgr.


Somewhere at/after bootmgr things are failing. Now this could be because of 
issues with iPXE, wimboot, the BIOS, or something else, but at least we know 
bootmgr or something later in the boot process are executing when things break.



If you have a functional Windows 8/Server 2012 or newer machine, you can copy 
your BCD file over to it, open a command prompt, and run the bcdedit command: 
bcdedit /store <path to your bcd file> /set {default} bootmenupolicy legacy

Bcdedit will modify the BCD file to use the legacy boot menu policy, which for 
our purposes will change the visual boot flow to go from iPXE/wimboot -> two 
progress loading bars -> the Windows logo, and further narrow down where things 
go wrong.



If you don't have a Windows machine you can use, for this test you can also try 
using this BCD file I've applied the setting to: 
https://onedrive.live.com/redir?resid=1F9FB6FE110265E6!2126&authkey=!AN_v1cLMXND2bVM&ithint=file%2c


Let us know what you see on boot as a result of trying this change!

Hi Ian,

I have tried on a couple of physical servers (same types) and see same issue.

After commenting initrd for BCD I do see an error screen (Recovery screen 
complaining about missing BCD).

I am not sure how do I run bcdedit without OS being loaded. Can you explain ?

Thanks a lot for your help.

Amit

Does the problem only happen on that machine, or do other, different, physical 
machines have the same problem?


Also, let's try to narrow down where things are going wrong. If you comment out 
the initrd for the BCD, do you see an error after everything is downloaded? If 
so, we know we're making it that far.

If so, can you use bcdedit to enable the legacy menu: bcdedit /store <path to 
your bcd file> /set {default} bootmenupolicy legacy

That will cause a few loading bars before you should see the Windows logo 
(which we're not reaching). What do you see in this case?

Hi Ian,

The new wimboot did solve the issue with Server 2012 R2 of "bootmgr.exe not 
found". But even in this case I am left with a blank screen after all files 
finish loading. Also to re-iterate the same script works on a VM on xen but 
gives a blank screen on a physical server.

Thanks
Amit

Ok, great. This should be pretty straightforward then. There were some changes 
to how bootmgr.exe was stored in bootmgr and wimboot was recently updated to 
support this. Can you grab the latest version from here and see if it resolves 
your issue - https://git.ipxe.org/releases/wimboot/wimboot-latest.zip ?


If that does not work, please try directly using bootmgr.exe (thus avoiding 
wimboot extracting it) by grabbing the file from inside the winpe.wim file at 
Windows\Boot\PXE\bootmgr.exe

Server 2012. This is the script

#!ipxe

initrd ${base}/winpe.wim                        boot.wim

echo ======================================================================

boot


Server 2012 R2 doesn't work atall. I get an bootmgr.exe not found error. Is 
there any fix available for this ?

Thanks
Amit

Server 2012 or Server 2012 R2? Can you please share the wimboot portion of your 
ipxe script?

Thanks!

Hi,
I am trying to install Windows Server 2012 on physical servers. Followed the 
instructions here http://ipxe.org/wimboot. After loading all the files I see a 
blank screen. I found several posts with this issue but with no definitive 
solution.

http://forum.ipxe.org/showthread.php?tid=7085
http://forum.ipxe.org/showthread.php?tid=7121
http://lists.ipxe.org/pipermail/ipxe-devel/2013-January/002176.html

I added the missing font, made sure the bios is at latest, etc.

The same task works fine on a VM hosted on Xen but doesn't work on a physical 
servers. These are some hardware details

"bios_vendor":"HP",
"bios_version":"P58",
"bios_release_date":"05/02/2011",
"manufacturer":"HP",
"productname":"ProLiant DL360 G5",
"serialnumber":"USE839N9CA",
"uuid":"33393935-3234-5553-4538-33394E394341",
"type":"Rack Mount Chassis"

Are there any know issues ? Any help is appreciated.

Thanks
Amit
