Adding Windows 7/8/10 which have large >4GB Install.wim/Install.esd files
In this case, you can just drag-and-drop the Windows ISO onto the MPI_FAT32 shortcut to make a .imgPTN file. The special instructions below do not need to be followed. You can then use the FAT32 .imgPTN file to MBR or UEFI-boot.
Your E2B USB drive must be formatted as NTFS (or possibly exFAT) in order to hold files of a size greater than 4GB.
Switch_E2B.exe will not work with ExFAT drives, so I recommend using NTFS for the E2B USB drive.
Fixes-disk E2B drives
- Place ISOs in \_ISO\WINDOWS\xxx folders (MBR booting only - needs a Helper Flash drive)
- Make FAT32 .imgPTN files using MakePartImage and place them in the \_ISO\MAINMENU or \_ISO\WIN folder (supports UEFI and MBR booting)
- Place ISOs in \_ISO\WINDOWS\xxx folders (MBR booting only - needs a Helper Flash drive if using a USB HDD) - E2B drive must be formatted as NTFS
- Split the install.wim file and make a FAT32 .imgPTN file (see Method 1 below) (supports UEFI and MBR booting)
- Make two image files, one FAT32 and the other NTFS (see Methods 2/3/4 below) (supports UEFI and MBR booting)
- Add a second FAT32 partition to your E2B USB drive and use one NTFS .imgPTN file (Method 5)
You can UEFI-boot directly from the MBR\CSM menu by using the Clover boot option in the CSM menu - no need to reboot and select the 'BIOS' UEFI USB boot option. However, some systems may crash when loading Clover.
Use WinNTSetup instead?
UEFI booting - How to add Windows 7/8/10 installers with >4GB install.wim files
Note: Methods 1, 4 and 5 can be used if E2B is on a Removable USB Flash drive or Fixed Disk type.
Methods 2 and 3 are for Fixed Disk USB drives only because the 2nd partition will not be accessible to Windows.
Method 5 requires you to add a 2nd FAT32 partition to your E2B USB drive - Removable or Fixed Disk type (it can be used for file storage or other purposes at the same time)
Please note: Many UEFI systems will not list the E2B drive in the UEFI boot list if it contains more than one partition, therefore using two partition images (Methods 2-5) may not work on every type of system!
Method 1 - FAT32 single-partition using split wim files (Fixed or Removable - *recommended)
- Download Split_WinISO and extract it to the MPI Folder.
- Then run Split_WinISO.exe from the MPI folder and click on the ISO button to select a Windows Installer ISO file.
- Check that at least one WIM or ESD file is listed and then click on the CONVERT button.
- Answer the questions.
if you experience problems (if it prompts for Product Key or 'license' error, it will be because the EI.cfg file contents are not correct or the wrong Product Key.)
If you have a install.esd file, you can convert it to a .WIM file and then split the WIM file.
See here for a script that will convert the .esd file to a single large .wim file using DISM (all images inside the .esd are converted).Use WinToolKit or DISM to split the file - DISM /Split-Image /ImageFile:d:\temp\sources\install.wim /SWMFile:d:\temp\sources\install.swm /FileSize:30001. Extract all files from ISO to empty temp folder2. Convert install.esd to install.wim using script3. Split install.wim to install.swm and install2.swm (choose 3GB max size)4. Replace install.esd with install.swm and install2.swm (in same folder)5. Drag-and-drop temp folder onto MPI_FAT32 shortcut to make .imgPTN file
Method 2 - using two partitions (Fixed-disk UFD only)
- Can UEFI boot via BIOS
- Can UEFI boot via Clover
- Can MBR boot via BIOS
Method 3 - using two partitions and Clover (1st Ptn = FAT32) (Fixed-disk USB only)
- Can UEFI boot via system firmware to UEFI files on 1st ptn only (if any EFI files present instead of EFI_TOGO_V2 - e.g. memtest86)
- Can UEFI boot via MBR and Clover to 32-bit and 64-bit NTFS partition
- Can boot via UEFI firmware to EFI boot files NTFS partition if EFI_TOGO_V2 used on FAT32 partition.
- Can MBR boot to 1st ptn payload
- Can MBR boot to bootmgr and Windows installer on 2nd ptn
Method 4 - using NTFS+FAT32 partitions and Clover (NTFS Fixed or Removable drive) UEFI-boot, Clover and MBR boot
EFI_TOGO_V2 can be also downloaded from the E2B Alternate Download - Other files area. It supports 32-bit and 64-bit UEFI systems.If you use an empty folder instead of the EFI_TOGO_V2 folder for the FAT32 partition, then it will not be capable of booting via a UEFI system (only by MBR booting + Clover -> UEFI Windows).An alternative is to use E2B_UEFI_BOOT_ADDON_NTFS64 - this boots to rEFInd UEFI boot manager + NTFS driver - from there you can boot to any EFI boot file present on the disk via rEFInd icon menu (press ENTER if 'map error') - 64-bit UEFI only.
- for MBR-booting - boot to the NTFS partition directly
- for UEFI-booting via Clover - MBR boot to the CSM menu and run Clover which will then UEFI-boot
- for UEFI-booting from system firmware - pick the UEFI boot option (if your UEFI BIOS lists your drive in the boot list - not all do!)
Note however that Windows 8.1 ToGo and Win10ToGo do not boot from a removable drive (unless you use a VHD file to hold the image).
Method 5 - Add a 2nd FAT32 partition to your E2B drive (Fixed or Removable - may not work on all systems)
WARNING: The big disadvantage with this method, is that you may not be able to MBR-boot to the E2B or CSM menu on some systems! This is because some systems will just give a UEFI boot option if a valid UEFI boot file is present and will not present you with an MBR boot option. If this happens, I suggest you temporarily rename the \EFI folder in order to be able to boot to E2B on that system.
PTN1: NTFS E2B
PTN2: FAT32 300MB or larger (it can be FAT instead of FAT32 if you want it to be smaller)
You can use Easeus Home Paritition Master (be careful to avoid the extra PUPs when you install it!) for this (it can make mulltiple partitions on Removable USB drives).
2. Copy Pete Batard's UEFI:NTFS files to the FAT32 partition (can be downloaded as EFI_TO GO_V2).
There should be a \EFI folder in the root.
Once made, we have an E2B NTFS volume in PTN1 to which we can now add large Windows Install AIO files as follows:
1. Drag-and-drop the source ISO or folder onto the MPI_NTFS Desktop shortcut to make a .imgPTN file.
2. Copy the .imgPTN file to the E2B USB drive (e.g. the \_ISO\WINDOWS\WIN8 folder or \_ISO\MAINMENU, etc.)
3. Rename the file to use a .imgPTNLBAa23 file extension.
Now you can switch to the .imgPTNLBAa23 file (using the E2B menu or Switch_E2B) and then MBR or UEFI-boot.
We don't need to use two .imgPTN files and the last partition will always be the UEFI boot file partition so we have no 'partition order' problem.
