Creating A USB Drive

This appendix creates a bootable USB drive for installing Analytics.

Creating the USB Boot Drive

Copy the ISO image to the USB drive to make it a bootable disk to install the Analytics software from a USB drive. It is available in Windows, MacOS, or Linux.

Creating the USB Boot Drive with MacOS X

Complete the following steps to create a bootable USB drive on MacOS X

Insert the USB drive into a USB port on the Macintosh.
It automatically mounts the drive but must be unmounted to create a bootable disk.
Open a Mac OS terminal window.
Enter the diskutil command to list all the mounted disks, as in the following example:
```
diskutil list
```

MacOS Disk Utility

Use the MacOS Disk Utility GUI application (applications/utilities) to identify the mounted disks and unmount the USB drive.

Identify the /dev/disk<x> label for the inserted USB drive.
Unmount the USB drive (this is different than ejecting) using the following command.
```
diskutil unmountdisk /dev/disk<x>
```
Replace <x> with the unique numeric identifier assigned by the system.
Enter the sudo dd command in the terminal window to make the USB drive bootable.
```
sudo dd if=<path to iso image> of=/dev/rdisk<x> bs=1024m
```
Note: Using the dd command with the wrong disk name can erase the installed OS or other vital information.
Use this command to copy the appliance ISO image to the USB drive. Using /dev/rdisk makes the copying faster (rdisk stands for a raw disk).

Replace <x> with the drive identifier for the USB drive and replace <path to iso image> with the file name and path to the location where you downloaded the ISO image.
the following command copies the file bmf-service-node.dmg to disk2:
```
sudo dd if= bmf-service-node.iso of=/dev/rdisk2 bs=1024m
```
Copying the image to the USB drive can take up to ten minutes.

To monitor the progress of the write operation, enter the following command in a separate terminal window.
```
$ while sudo killall -INFO dd; do sleep 5; done
```
Eject the drive by entering the following command:
```
disk util eject
```
Alternatively, select Eject from the File menu.

Building the USB Boot Image with Linux

Complete the following steps to create a bootable USB drive using Linux.

Insert the USB drive into a USB port on the Linux workstation.
Enter the following command to identify the USB drive in a Linux terminal window.
```
disk -lu
```
On Linux, the USB drive is typically /dev/sdb.
Verify that the USB drive is not currently mounted, or unmount it if it is. Use the mount command to list the currently mounted devices.
Use the sudo dd command to make the USB drive bootable by copying the ISO image.
```
# sudo dd if=<path to iso image> of=/dev/sdb bs=4096
```
Note: Using the dd command with the wrong disk name can erase the installed OS or other vital information.
Replace <path to iso image> with the file name and path to the location where you downloaded the ISO image. For example, the following command copies bmf-service-node.iso to the USB drive:
```
# sudo dd if=bmf-service-node.iso of=/dev/sdb bs=4096
```
Copying the image to the USB drive can take up to ten minutes.
Eject the USB drive from the Linux workstation.

Creating a USB Boot Image Using Windows

Several Windows utilities can build a USB boot image from an ISO image. The following procedure uses the Rufus bootable image program.

To build a USB boot image using Windows, complete the following steps.

Download the Rufus utility from https://rufus.akeo.ie/.
After downloading the utility, double-click the rufus.exe file.
The system displays the following dialog box:

Figure 1. User Account Control
Click OK to allow the changes required for installation.
The system displays the following dialog box:

Figure 2. Rufus: Create an ISO Image Option
To create a bootable disk select ISO Image.

Figure 3. Rufus: Select ISO Image
Click the CD-ROM icon.
The system displays the following dialog box:

Figure 4. Open ISO Image File
Select the file to use and click Open.
Click Start to burn the ISO image to USB.

Figure 5. Rufus: Start

If an upgrade to syslinux is required, the system will display the following dialog box.

Figure 6. User Account Control
If this prompt appears, click Yes to continue.
When prompted to use DD mode or ISO mode, choose ISO.
The system displays a warning that the data on the USB drive will be destroyed, and a new image will be installed.
