Using a Windows Computer to Prepare the USB Flash Drive
To prepare the USB flash drive on a Windows PC, follow these steps:
Step 1 Transfer the software recovery files onto the Windows computer, noting the directory where they are
stored.
Step 2 Insert the USB flash drive into a USB port on the PC.
Step 3 Open My Computer.
Step 4 Right click on the Removable Disk (drive letter will vary with system) and select Format.
In the formatting tool, select FAT32 for the File System and check the Quick Format check box, and then
click Start. Click OK on the warning message. Close the formatting tool after the formatting is
complete.
Step 5 Double-click the Windows Unetbootin utility to run it.
Step 6 Select the Diskimage option and click the corresponding browse button (...) to select the
waas-rescue-cdrom-x.x.x.x-k9.iso image file.
Step 7 Ensure that USB Drive is selected in the Type pull-down list and that the correct drive letter is selected
for Drive.
Step 8 Click OK to install the bootable image on the USB flash drive. When the installation has completed,
click Exit.
Step 9 Drag copy the syslinux.cfg file onto the USB flash drive and confirm to replace. This file replaces the
existing file on the USB flash drive with one customized for your WAAS system.
Step 10 Remove the USB flash drive from the PC.
