For ISOs based on Windows XP, try a file extension of .isofira or .isomemF01. You can also try the .isowinvh and .isoHW file extensions.
Tip: If QRUN.g4b suggests an alternate file extension, enter A for Ask.
WinPE (Vista/7/8/10) non-WinBuilder ISOs
Try the .isoWinvh or .isoHW file extension.
For some PE ISOs you can also try .ISOPE or .ISOPE01, but these need a removable E2B USB flash drive or E2B HDD+WinHelper flash drive.
Alternatively, convert the ISO to a FAT32 .imgPTN file (works for E2B HDDs and Removable Flash drives too).
Note: You can make .imgPTNpartition image files from each ISO file and you don't need to 'fiddle' with INI files, etc., however the contents of the E2B partition will not be accessible once booted to WinPE. But, if you use the .imgPTNLBAa23 file extension, then partitions 2 and 3 of a E2B USB hard disk will be accessible from WinPE.
WinBuilder ISOs (Gandalf, ChrisR PEs, etc.)
Please update to E2B v1.90 or later.
E2B will automatically update the .INI files in the root of the E2B drive if a WinBuilder ISO is detected.
You must keep the filename extension as .ISO and the filename must not contain any spaces.
Most WinBuilder-based ISOs will load the ISO file as drive Y: when the Desktop loads.
To do this, WinPE needs to be told where the ISO file is, so they usually look for a .INI file in the root of a drive and which contains the location of the ISO file.
Most WinBuilder WinPE ISO files based on Vista/7/8/10 also require the use of the WinBuilder .ini file so that all the Desktop icons and programs are available. This .ini file (e.g. \Win7PESE.ini) is usually written together with the .iso file in the WinBuilder ISO build folder by the WinBuilder make scripts when the ISO is made.
WinBuilder ISOs boot like this...
ISO boots to WinPE
Internal script looks for a specific .ini file using MountPEMedia.exe + MountPEMedia.ini - e.g. \WIN10PESE.ini (or drive with \CdUsb.Y file)
Win10PESE.ini file contains path of where to find the ISO file
Internal script loads the ISO file as virtual CD drive Y: (usually needs a .iso file extension and no spaces in name to work)
Desktop icons + applications will now run correctly from Y:
Hint: A tell-tale sign of a WinBuilder ISO is that it will usually contain a \CdUsb.Y file in the root of the ISO.
IMPORTANT: WinBuilder ISO file names must contain no spaces.
The ISO may not be loaded as Y: if the filename contains spaces!
The file name must end with a .iso file extension or else it may not be loaded as the virtual CD Y: drive correctly.
Do not use .isodefault or .isodef or any other file extension as it may not work - you can use a .mnu file (see below).
See this page for how to suppress the auto-suggest text.
# .MNU file for WinBuilder ISOs - Check if CPU is 64-bit and boot without E2B messages
iftitle [checkrange 2,3 is64bit] Win10PESE_x64.ISO\n Boot silently and quickly
set redir=> nul
call /%grub%/QRUN.g4b $HOME$/Win10PESE_x64.ISO
How to tell if it has worked correctly
Many WinBuilder PE's will display a yellow warning triangle with an exclamation mark icon on the Desktop if it fails to load all the desktop icons (see screenshot below). If you double-click on the yellow triangle Desktop icon, and search the text file that is loaded, look for an ExternalIniFileName= entry (e.g. WIN10PESE.ini). This is the specific name of the .ini file that WinPE is looking for.
You must check to see if you have a Y: virtual CD drive present in Explorer (even if you do not get a Yellow warning triangle).
The yellow triangle icon indicates that some programs/features failed to load due to no .ini file being found.
For example, if you have a WinBuilder PE .ISO file from a Win7SE project build, the X:\Windows\system32\mountpemedia.ini file will specify an external INI file name of \Win7PESE.ini, so we need a file in the root of the E2B drive called Win7PESE.ini with the path and filename of the ISO you are using -
The filename of the .ini file used by the WinBulder PE ISO may vary depending on what PE build you are using. The filename must not contain spaces and must end with .iso (do not use .isodefault or any other file extension).
However, this will only work as long as you have just one WinBuilder PE ISO of each type (e.g. Win7PESE) on your E2B drive because, for example, you can only have one Win7PESE.ini file and thus only boot to one WinBuilder Win7PESE type of ISO file. See below for how to have multiple WinBuilder ISOs.
How to find the correct name of the .ini file for each ISO
Boot as a .ISO file and then double-click the yellow Desktop icon (see screenshot above) to find the ExternalIniFileName= entry.
Most WinBuilder PE builds have the file X:\Windows\system32\mountpemedia.ini built into the boot.wim file when WinBuilder makes the image. You can look at this file once the WinBuilder PE has booted, to see what it contains (see below). This file tells WinPE what the name and location of the PE ISO is, so that it can load it as drive Y:. However, this file also specifies an external INI file which WinPE will also look for. It is this external INI file that we need to provide on the E2B USB drive, but it must be of the same name that is specified by the mountpemedia.ini file - so check the X:\Windows\system32\mountpemedia.ini file if PE fails to load all Desktop icons.
Example X:\Windows\system32\mountpemedia.ini file showing where the external INI filename is specified.
ExternalIniFileName=Win7PESE.ini <<<<<< name of ini file used by WinBuilder ISO
Line1=CdUSB.Y or ISO NOT found !
The X:\Windows\system32\mountpemedia.ini file specifies an ISO file - in this case the WinBuilder PE ISO will look for \Win7PE_x86.ISO and so it will not find it. However, it also specifies the name of an external INI file which it expects to find at \Win7PESE.ini. We therefore need to ensure that this file is present on the root of the E2B USB drive and that it contains the true location of our ISO file.
Tip: If the WinPE ISO prompts you to 'Press ENTER to boot from CD\DVD', you can permanently fix this by changing the file extension to .isoBF (BF='Boot fix') - then boot to the ISO - then quit and rename the ISO file back to it's original file extension. This will patch the ISO file.
E2B + Multiple WinBuilder ISOs (Removable and Fixed-disk drives)
E2B v1.90+ will automatically detect if a .ISO file contains WinBuilder and will modify the \Win7PESE.ini, \Win8PESE.ini and \Win10PESE.ini files in the root of the E2B drive. The .ISO file should then be correctly loaded as Y:.
This works for MediCat, WinPEYol and most other WinBuilder ISOs that use these .INI files.
If you change the file extension from .iso, it may not work!
If you don't want to see any boot text, do not use a .isodefault file extension - instead use a .iso file with a .mnu file (see below) or define the redir variable in MyE2B.cfg to suppress the auto-suggestion feature of E2B and reduce informational messages (not recommended).
Using a .mnu file for non-standard .ini files (E2B v1.90+)
If your WinBuilder ISO does not use any of the .INI files already present in E2B, you must create the a blank .INI file in the root of the E2B drive and use a .mnu file.
Place the .iso and .mnu file in a 3rd-level folder (e.g. \_ISO\WINPE\MNU) so that only the .mnu file appears in the E2B menu.
# WinBuilder sample .mnu file - example for Gandalf x86 64-bit WinPE 2016-11 version (requires E2B v1.90 or later)
# click on the Desktop Yellow Warning Triangle to find .ini file name for each WinBuilder ISO
# ISO filename must not contain spaces or it won't be loaded as Y: virtual CD!!!
# You must create the \WIN10PESE.ini file in root of E2B drive and fill it with 1000 characters of random junk
title Gandalf PE 64-bit WinBuilder ISO\n Boot a WinBuilder ISO
if not exist $HOME$/%ISOFN% echo ERROR: $HOME$/%ISOFN% NOT FOUND! && pause
if exist $HOME$/%ISOFN% call /%grub%/QRUN.g4b force.isoWB $HOME$/%ISOFN%
Using a .isoWB and WB folder (old, more complicated method!)
If you have several ISOs that have been created by the same WinBuilder project (for instance you have Win10PESE_x86 and Win10PESE_x64), you can use the .isoWB file extension for each ISO as described below (E2B v1.30 and later):
1. Copy the .INI file used by your WinBuilder ISO (or make one) to the root of the E2B USB drive - this file is usually found in the same folder as the ISO when made by WinBuilder. e.g. \Win7PESE.ini. The contents of the file are not important, but the file name is critical and must not be changed - it must be the same name that is looked for by the WinBuilder ISO.
2. Add extra spaces to the .ini file using NotePad to make a larger file (e.g. by adding 100 spaces to the end of it).
The .INI file MUST be at least as big as the .WB file that you are going to create.
3. Copy your WinBuilder PE .ISO file to the desired menu folder (e.g. \_ISO\MAINMENU or \_ISO\WINPE) - do NOT uses any spaces in the filename.
Use an ISO filename of less than 20 characters with no spaces - e.g. Gandalf_WinPE_x64.isoWB is 17 characters.
4. Rename the ISO file extension to .isoWB (e.g. \_ISO\MAINMENU\WBPE.isoWB)
5. Make a subfolder called WB (e.g. \_ISO\MAINMENU\WB) - the sub-folder MUST be named WB - this cannot be changed.
6. Create a text file in the WB folder with the same name as the .isoWB file but with a .WB file extension - e.g. \_ISO\MAINMENU\WB\WBPE.WB)
The contents of the .WB file should contain two lines (the text in red should be changed to match the name of the .INI file used by your WinBuilder ISO (the one you made in the root of the E2B drive in Step 1), make sure you keep the case of the word IniName the same, don't use ININAME or ininame - only IniName will work!):
7. (optional) Create a .txt file for the .isoWB file so that the menu entry is not just displayed as the filename, e.g.
title My WinPE ISO\n Boot the ISO using Easy2Boot
Example File Structure for ChrisR's Win10PESE project (must use a WB sub-folder)
\Win10PESE.ini <-- must be over 1KB (any contents inside - it is overwritten by E2B) \_ISO\WINPE\Win10PESE_x86.isoWB <-- WinBuilder PE ISO renamed to .isoWB \_ISO\WINPE\WB\Win10PESE_x86.WB <-- text file containing the name of the INI file used by the PE ISO (see step 6 above). Filename must match the .ISO filename.
For another example using WinPE-Yol.iso - see my blog article here.
Use a .mnu file for multiple WinBuilder ISOs (older method - even more complicated!)
If you prefer, you can instead use the .mnu file in the \_ISO\docs\Sample mnu files\WinBuilder_PE_Multiple_ISOs folder (v1.30 and later) for each WinBuilder PE ISO file.
Details are inside the ReadMe.txt file.
Note: The .WB file goes in the same folder as the .iso file when using a .mnu file.
Please note, if using pre-v.1.71 E2B versions, the INI file needs to be about 1000 bytes or larger if your E2B USB drive is an NTFS volume.
An alternative way to boot WinBuilder or WinPE ISOs
Note: For this method, all the WinBulder .ISO files need to be in the root of the E2B drive. They must not be renamed. No INI file is required.
1. Ensure there is no \Win7PESE.ini file (or whatever is used by the PE ISO) or \CdUSB.y file in the root of any drive. Delete them if they exist
2. Copy your WinPE ISO file to the root of you E2B drive - e.g. U:\ - do NOT rename the ISO file
3. Copy the WinBuilder_ISO.mnu file to an E2B menu folder (e.g. U:\_ISO\MAINMENU\MNU)
4. Rename and edit the .mnu file (any name xxxxxxx.mnu will work!) to contain the correct ISO name of your WinBuilder PE ISO. Delete the menu entry that is not required .from the example below
title WinBuilder ISO \n Use for most WinBuilder PE ISOs
/%grub%/qrun.g4b force.iso01 /%ISO%
title WinBuilder ISO + Load ISO as new drive letter \n Use for WinBuilder PE ISOs\n which don't auto-load the ISO as Y:
/%grub%/qrun.g4b force.isope01 /%ISO%
Repeat these steps for each WinBuilder ISO. Note that the second menu requires an E2B USB Flash drive (or an E2B USB HDD+USB Flash 'Helper' drive).
If you are using WinFE (see here for how to make a WinFE ISO), in order to get PStart to work correctly, you will need to Mount the E2B USB drive using the WinFE Write Protect Tool that will automatically run on startup (it can be mounted as ReadOnly or Read\Write).
If you want the ISOs to be located in \_ISO\MAINMENU\MNU then you will need to specify the path in the WinBuilder - Finals - Create ISO parameters before you click on the Play arrow, as shown below:
The ISO (WinFESS.ISO in this case) must be placed in the \_ISO\MAINMENU\MNU
The path in the .mnu file must also be changed.
This can be added to E2B as a FAT32 .imgPTN file (details as in previous blog here).
Another way to boot it, is to rename the ISO to it's original WinBuilder name of \WIN10PESE_x64.ISO (for the 64-bit version) and place it in the root of the E2B drive. Then copy the "\_ISO\docs\Sample mnu files\Windows\WinBuilderPE_ISO.mnu" to a suitable menu folder (e.g. \_ISO\WIN) and then edit it with the correct ISO name.
title Gandalf 10 x64\n Boot to Gandalf PE
/%grub%/qrun.g4b force.iso01 /%ISO%
Note that this only allows you to have one ISO on the E2B USB drive of that name, so you cannot add more, similar WinBuilder ISOs unless you use the E2B .isoWB file extension.
For 'vanilla' PE ISOs which don't use Y:
E2B recognises a special file extension of .isoPE and .isoPE01. These can be used for WinPE v2 (Vista), v3 (Win7) and v4 (Win8/10) based .iso files.
If you use the .isoPE file extension AND the E2B boot drive is a Removable USB Flash drive (or you have an E2B 'Helper' USB flash drive connected) then, when wpeinit runs to initialise the network when the WinPE ISO boots, the WinPE ISO file will be mounted as a virtual DVD drive and given the letter Y: by default. This means that for WinPE (e.g. WinBuilder) projects, you can boot directly from a .isoPE file and the auxilliary files which the WinPE environment expects to find on the Y: DVD drive, will be present on the Y: drive. Thus the PStart menu items, etc. should work as if it had booted from a DVD.
If you wish to have the ISO load as a different drive letter, then you need to make a new file with the same filename as the ISO but with a .cmd file extension (in the same folder as the .isoPE file).
e.g. \_ISO\MAINMENU\PE3x86.cmd if the iso was at \_ISO\MAINMENU\PE3x86.isoPE01
The .cmd file should contain a line similar to the one below:
In this way, you do not need to remember what drive letter each different ISO uses, once you have made the .cmd files for each of your WinPE ISO files.
Note: E2B v1.91+ supports the use of ISOLETTER=B: which can be used if you must have a \sources folder on the E2B USB drive but want Setup to find the ISO file's Sources folder on drive B: first.
Run your own .cmd file
If you require a .cmd file to run some operations after the ISO has been mounted but before PE has fully loaded (e.g. to copy files, etc.), you can define a POSTCMD variable, e.g. if the ISO was called \_ISO\WINPE\Winpe\123.iso, then here are 4 different examples of what could be in your 123.cmd file:
REM run \_ISO\WINPE\Winpe\123_Custom.cmd after the ISO file has been loaded as a virtual drive
set POSTCMD= %~pn0_Custom.cmd
REM run \_ISO\WINPE\Winpe\xyz.cmd after the ISO file has been loaded as a virtual drive
set POSTCMD= %~p0xyz.cmd
REM Run a cmd file from the E2B USB drive after the ISO file has been loaded as a virtual drive
REM Run a cmd file from the ISO after the ISO file has been loaded as a virtual drive
For WinBuilder PE ISOs, you can force it to load the Desktop icons by having a .cmd file on the E2B drive containing the correct commands - e.g.
The .isoPE01 file extension has the same affect as the .isoPE extension, except that it swaps over the USB boot drive 0 with drive 1 (the internal HDD) before booting to the ISO (BIOS swap only). This may be useful for running WinPE ISOs that normally contain recovery software which expects HD0 to be the 'system' HDD.
Example .cmd file to replace an existing CD-ROM drive letter with that of the ISO
for /f "skip=1 delims=" %%i in ('wmic cdrom get drive') do set letter=%%i && goto :end
Thanks to (NF) for this example.
Note: If you also add a .txt file for each ISO, then you can change the menu text displayed for each file.
