By default only first step is enabled. Once choice is made in first step, next step will enable automatically.

Step1: - Wizard scans and lists all attached USB drives in first drop down field. Select the USB drive which you want to use for this process.

Do not check the option “Show All Drives”. Selecting this option will display all drives including hard disk partitions in drop down list which increases the chances of selecting wrong drive. To minimize the chances of selecting hard disk partition, keep this option unchecked. If wizard is not displaying attached USB drive in drop down list, remove and attach the USB drive again in system. If wizard still does not display the USB drive, try replacing and formatting the drive.

Once USB drive is selected from list, wizard will show the format options in right side. Although wizard can format pen drive with NTFS file system, but it should not be used for installation purpose.

NTFS is not supported by all OS. Unless you are going to store a file larger than 4GB in this pen drive, there is no need to use NTFS file system here.

Select Fat32 Format
