NOTE – on 32-bit UEFI systems, references to the UEFI boot file boot圆4.efi will need to be replaced with \bootia32.efi.
The following paths (relative to the HTTP root directory) are used in the instructions below – This is a compressed archive containing the WinPE Operating System files. *.wim – Windows Image File (typically boot.wim or winpe.wim or winre.wim).This file (typically boot.sdi) is used to create the RAMDISK and filesystem used to mount the files in *.wim. A registry hive containing boot settings used to load the Windows NT6.* operating system – in this case WinPE. NOTE – for use on Client systems with UEFI Firmware. This file may be extracted by wimboot on the fly (from *.wim – see below). NOTE – for use on Client systems with BIOS Firmware, or on UEFI systems booting in CSM mode. You can disable this behaviour by using the rawbcd command-line option….”Īs a minimum, the following files are required for booting WinPE via wimboot – kernel wimboot rawbcd) – “…wimboot will automatically patch standard BIOS-compatible boot configuration data (BCD) files to allow them to be used on UEFI systems, by changing all occurrences of the string ”.exe” to ”.efi”. You can use the index= command-line option to select the image to be booted….”. kernel wimboot index=2) – “…A WIM file can contain multiple bootable images. This command may be useful for troubleshooting. kernel wimboot pause) – “…This will instruct wimboot to wait for a keypress before booting Windows, to give you a further opportunity to observe any messages that may be displayed. The wimboot page lists several commands that can be passed to wimboot (e.g. Windows Preinstallation Environment (WinPE) and file dependencies required for PXE booting WinPE are covered in detail in the WinPE page of this document – please read the WinPE page first, prior to this page.
wimboot allows you to use a single procedure and set of files to boot under both BIOS and UEFI environments…” With a Gigabit Ethernet network, a typical 200MB WinPE image should download in less than two seconds…. You can use wimboot with iPXE to boot Windows PE via HTTP. It enables you to boot a Windows PE (WinPE) environment from a RAM disk, without wasting the memory used for the RAM disk image. “…wimboot is a boot loader for Windows Imaging Format (.wim) files.
