Hello, I'm getting "Input/Output error" when trying to load a customized wim file.

Steps to create wim file:

Code:

Installed Windows 2012 R2 onto physical server

Installed drivers and an application

booted server to winpe and captured partition with DSIM

The .wim file is just under 6Gb in size.

Here is the code in the .ipxe menu:

Code:

:VSS

imgfree

kernel ${boot-url}/iPXE/tools/winpe_64_VSS/wimboot gui

initrd ${boot-url}/iPXE/tools/winpe_64_VSS/media/Boot/BCD BCD

initrd ${boot-url}/iPXE/tools/winpe_64_VSS/media/Boot/Fonts/segmono_boot.ttf segmono_boot.ttf

initrd ${boot-url}/iPXE/tools/winpe_64_VSS/media/Boot/Fonts/segoe_slboot.ttf segoe_slboot.ttf

initrd ${boot-url}/iPXE/tools/winpe_64_VSS/media/Boot/Fonts/wgl4_boot.ttf    wgl4_boot.ttf

initrd ${boot-url}/iPXE/tools/winpe_64_VSS/media/Boot/boot.sdi boot.sdi

initrd ${boot-url}/iPXE/tools/winpe_64_VSS/media/sources/boot.wim boot.wim

boot || goto failed

I have tried booting to this with several different servers. They all have over 100Gb of RAM and a mix of Qlogic, Intel, and BCOM NIC cards.

Has anyone tried this or have any suggestions?

Follow the helpful link in the error message that iPXE gave you: http://ipxe.org/1d0c6239. Then track down and fix the problem with your web server that iPXE is reporting.

That's too large to load under BIOS. The whole image needs to fit below 2GB, due to hardcoded assumptions within the Windows kernel.

You will need to switch your system to a native UEFI boot in order to use a 6GB image. You should be able to use the same iPXE script and wimboot binary under UEFI.
