Creating a bootable Win7PE using Winbuilder.          Updated: 2014-05-13



Building this Win7PE boot disk will require a Windows7 source!

Building host: Windows XP/Vista/7.

Hard drive space:  2 GB of free space.

RAM:  Host and target system: 2 GB or more!

General tips:

1. Turn off ALL other programs (including antivirus) running in background before using Winbuilder.

2. Only use Winbuilder after a fresh reboot!

3. Turn off  UAC (User Account Control) in Windows7/Vista/8.

4. Run Winbuilder.exe as "Administrator"!

Step 1:

To avoid any "issues", download & use this Windows 7 ISO as source (2.4GB)

It is recommended to use a download manager (FlashGet, Free Download Manager, WellGet, Fresh Download, etc) if you're downloading large files.

Extract the contents of the Windows7 ISO to a drive/folder of your choice on the hard drive, for example to D:\Windows7

Step 2:

Download the light 45MB Win7PE building project with 50 application scripts here

Password: aljo.

Unzip the Win7pe package to, for example, C:\Win7pe or D:\Win7pe

Note: Donate here to get the full 300MB package with 100 extra new app scripts including AntiVirus, Partitioning, Imaging + a lot more.

Or/and send a "no donate" request here.

Step 3:

Open folder C:\Win7pe  & start WinBuilder by executing WinBuilder.exe.

In Vista/Windows7/8, right click WinBuilder.exe and choose "Run As Administrator".

Point to the source in the main screen as showing in the picture below. In this case: D:\Windows7 and click the blue “Play” button.

The ISO file will now be made in about 5-10 minutes!

Note: “Special” Lan/Wlan drivers can be added to the PE, using this guide.

The ISO file can now be burned to CD/DVD by using a CD/DVD burner application capable of burning ISO files.

Recommended software: Imgburn


Step 4:

Create the Win7PE boot disk as an USB Flash Drive (UFD) using Rufus.

Download Rufus here. Rufus homepage is here.

Start Rufus.exe and

1. Select your UFD device

2. Choose NTFS format

3. Select your 7peavir.ISO

4. Click start

Now the ISO files is copied to the UFD:


The bootable Win7PE is now ready to be used from USB.
