How to Make a Hiren's Bootable USB
Hiren's Boot CD is a set of system-recovery and troubleshooting utilities. Typically the distribution would be burned to a CD-R, but with the lowered cost of USB pen drives it is often more convenient to make a bootable USB version of the utility. Using the free Unetbootin utility, which makes bootable USB pen drives, and a 256MB pen drive or larger, you can quickly create a bootable USB version of the Hiren's system utilities.
Download both Unetbootin and the latest ISO disc image of the Hiren's BootCD (see "Resources"). Install Unetbootin and launch the application from the shortcut in your programs menu.
Click the "Disk Image" radial option and select "ISO" from the drop-down box. Click the "..." button and select the Hiren's BootCD ISO file from your hard drive.
Click the "Type" drop-down box and choose "USB Drive" from the options. Click the "Drive" drop-down box and select your USB pen drive's letter from the list. Click "Ok" to create the Hiren's bootable USB.
