[ipxe-devel] wimboot issue with server 2012 on physical servers

Wed Apr 30 16:20:50 UTC 2014

You can copy it out from inside of a WIM file. It will be located inside the WIM at Windows\Boot\PXE\bootmgr.exe. You can also try using this one here: https://onedrive.live.com/redir?resid=1F9FB6FE110265E6!2127&authkey=!AKCWPhnsiS0gJts&ithint=file%2c.exe (it is signed by Microsoft for what that's worth) 

Sorry we haven't been able to identify what is unique about this HP server that is causing trouble :/

Additional fonts didn’t work. I guess last thing to try is the bootmgr.exe. Ian, so how do I generate this file ? Are there any instructions ?
Thanks

Yeah, in terms of other ideas, trying to use additional fonts is a good one. I would also again suggest trying bootmgr.exe directly instead of 'bootmgr'.

Good to know it works via CD.. very strange.

Blank screen is mostly caused by an error occurring during the boot of your wim file while the fonts to display the error messages are missing.
If your build system created a ISO file you extracted the wim file from you can check if this is the cause for the blank screen.
1.    
Boot your server using a CD/DVD created with that very ISO and see, if this works.
2.    
If yes – check the folder “Boot\Fonts” on that CD/DVD. You will see the necessary fonts in there. Normally you don’t need the Japanese and Korean fonts. Then load the necessary
 fonts via iPXE and see if you get a readable error message. You can reduce the maximum set of fonts then to the necessary minimum and try to resolve the causing error after that.

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

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.

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

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

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
