Download and install TotalMounter
We can only download TotalMounter as a free trial, but it is enough to create a System Repair Disc ISO.
The installation won’t attempt to install useless third-party programs or toolbars. It just needs to install a device driver for the virtual drive.
Create a System Repair Disc ISO
After the installation, we run TotalMounter and select Device -> Mount -> Virtual CD/DVD-RW.
On the “Mount Device” window we click on “Browse” and type the name of the ISO we want to create, in the example “System Repair Disc.iso.” Just make sure you have selected “All Files,” or else it will become “System Repair Disc.iso.img.”
We can save the file wherever we want, in our Documents folder, on the Desktop, anywhere.
After that, we click on Finish.
Now, the Computer will show a new drive, with the first available drive letter.
This new DVD-RW drive will also show up in the “System Repair Disc” creation utility.
We just need to click on Create disc. In a couple of seconds, we will have a System Repair Disc ISO.
Before closing TotalMounter, make sure you unmount the virtual drive.
After that, we can uninstall TotalMounter if we don’t want it anymore.
Create a System Repair USB
Unfortunately, most of them won’t work to create a System Repair USB. They will be able to create the USB, but when we try to run most of its tools, we will get weird error messages.
The solution to creating a proper System Repair USB is to download the trial version of PowerISO.
During the installation, we should remove all file associations – if we don’t intend to keep PowerISO – and uncheck the “Autostart on boot up” box.
After the installation, we right-click on the PowerISO icon, and select “Run as administrator.”
We choose to “Continue Unregistered.”
Then we go to Tools -> Create Bootable USB Drive.
At the Source Image File, we click the folder icon and select our System Repair Disc ISO…
…then we select the Destination USB Drive – any thumb drive 256MB or larger will do – click start and confirm that the procedure will rewrite any files already on the USB drive.
And that’s it. We can now use the System Repair USB to boot and troubleshoot our operating system.
What tools does the Windows 7 System Repair Disc contain?
After we set up the BIOS/UEFI to boot from DVD or USB, we will get a prompt to press any key, such as when we first install Windows.
By pressing any key, the System Repair Disc will load, with a screen that reminds us of Windows Vista.
Once it loads, we select a keyboard input method.
In most cases, if the operating system isn’t too damaged, the System Repair Disc will recognize it…
…and we will get five system recovery and diagnostic options, and several more options through the command prompt.
If this menu looks familiar, it is the same menu and the same tools we get when we select “Repair your Computer” on the Windows installation DVD.
