Ophcrack

Tools used to create USB Ophcrack:

• Windows Computer (Windows XP is used here)
• 512 MB or larger portable device (USB stick)
• Ophcrack Live CD and usboph.zip

Creating bootable USB Ophcrack:

1. First, create a "New Directory" to house your work
2. Download Ophcrack Live CD to the new directory
3. Download and extract usboph.zip to the new directory
4. Click fixoph.bat and follow the onscreen instructions
5. Copy all the files from the Ophcrack directory to your USB device
6. From your USB device, click makeboot.bat and follow the instructions to make the drive bootable

If all goes well, you should be booting from the USB stick into a mini SLAX environment. Ophcrack is launched automatically after boot.

How to fix Could not find kernel image: linux error:

Use the following troubleshooting guide to assist in fixing the error.

1. Make sure that the syslinux.cfg file exists on the USB flash drive. Depending on which version of linux you have installed to your flash drive, the syslinux.cfg file should be found at the root of the drive or within the /boot/syslinux or /syslinux directory
2. If a file named isolinux.cfg exists and syslinux.cfg does not, rename isolinux.cfg to syslinux.cfg
3. If the syslinux.cfg file does exist and your still encountering the error, open the syslinux.cfg file with a text editor and make sure that the paths to your kernel and initrd files are correct.
