How To Create a System Repair USB Tool for Windows 7

November 2016


Most larger computers and laptops come with a system recovery CD that you can use in the event that you need repair your device. However, netbooks often don't have a CD/DVD drive and, therefore, can't be fixed with this type of disk.

To make up for this deficit, you can use this trick to make a system repair USB key, which can be used on netbooks without CD/DVD drives and PCs alike.

Create a System Repair USB Key on Windows 7

In order to complete this process, you will need a bootable USB key with over 165 MB of free space.

Preparing the USB Key

To open the command prompt, go to Run > CMD.

Next, enter DISKPART > list disk open the DISKPART tool.

Look for the number assigned to your USB key from the list that appears, then enter select disk [number of USB key] > clean.

This will delete this partition. To create a new one, enter create partition primary > active.

This will make your partition active (bootable). Continue the process by entering format fs=fat32 quick > assign.

To exit DISKPART and, then, the command prompt, enter exit twice in the field.

Display Hidden Files and Folders

Go to Start > Computer.

Click Organize > Folder Options and Search > View tab.

Fill in the check box next to View hidden files, folders and drives, and empty the check box next to Hide extensions for files whose type is known and Hide protected files of the operating system.

Creating Directories and Copying the Necessary Files

Create a folder on your desktop called Win7. Open the folder, and create two folders titled Sources and Boot:


Copy the C:WindowsBootPCATbootmgr file in the Win7 directory.

In the boot directory, copy the C:WindowsBootDVDPCATboot.sdi, C:WindowsBootDVDPCATBCD, and C:WindowsBootDVDPCATfr-FRbootfix.bin files.

In the source directory, copy the C:Recovery486aab42-cf02-11de-be22-c44fb1debe9dwinre.wim file.


Copy the contents of the Win7 folder to the USB key. Rename the BCD file to bcd and the winre.wim to boot.wim on your USB flash drive.
