Installation Section

To get started with the Red Hat Enterprise Linux 9 Beta, you’ll first need to download the ISO image. Once you have the image, you can burn it to a disc or create a bootable USB drive. If you choose to go the USB route, you’ll need a minimum of 4GB of storage space. Insert your USB stick into your computer and make sure you’re using an up-to-date version of Fedora LiveUSB Creator or another utility that can work with UEFI computers. After connecting your USB device, find out what device name is assigned to it by running the following command: lsblk -f You should see something like /dev/sdb listed as the USB device. In this case, we’ll use /dev/sdb1. Next, type mkdir followed by a directory location on your system. For example: mkdir /mnt/usbstick1/. Then type mount followed by the mount point and file system type. In this case, we’ll use mount /dev/sdb1 /mnt/usbstick1. Finally, run the dd if=imagefile.iso of=/dev/sdb1 bs=4M. That’s all there is to it!
