2.2. Making Minimal Boot Media
- to boot the system to install Red Hat Enterprise Linux over a network
- to boot the system to install Red Hat Enterprise Linux from a hard drive
- to use a kickstart file during installation (refer to Section 32.9.1, “Creating Kickstart Boot Media”
- to commence a network or hard-drive installation or to use an anaconda update or a kickstart file with a DVD installation.
- Download the ISO image file named
rhel-variant-version-architecture-boot.isothat is available at the same location as the images of the Red Hat Enterprise Linux 6.9 installation DVD — refer to Chapter 1, Obtaining Red Hat Enterprise Linux.
- Burn the
.isofile to a blank CD or DVD using the same procedure detailed in Section 2.1, “Making an Installation DVD” for the installation disc.
.isofile to a USB device with the dd command. As the
.isofile is only around 200 MB in size, you do not need an especially large USB flash drive.
2.2.1. Minimal USB Boot Media for BIOS-based Systems
- Plug in your USB flash drive.
- Find the flash drive's device name. If the media has a volume name, use it to look up the device name in
/dev/disk/by-label, or use the
findfs LABEL=MyLabelIf the media does not have a volume name or you do not know it, you can also use the
dmesgcommand shortly after connecting the media to your computer. After running the command, the device name (such as
sdc) should appear in several lines towards the end of the output.
- Become root:
- Use the
ddcommand to transfer the boot ISO image to the USB device:
# dd if=path/image_name.iso of=/dev/devicewhere path/image_name.iso is the boot ISO image file that you downloaded and
deviceis the device name for the USB flash drive. Ensure you specify the device name (such as
sdc), not the partition name (such as
sdc1). For example:
# dd if=~/Downloads/RHEL6.9-Server-x86_64-boot.iso of=/dev/sdc
