This guide will help you fix failed to detect and mount CD-ROM problem when installing the latest edition of Kali Linux.
Step 1: Use Rufus to Create Your Bootable Kali USB
For this to work, you must use Rufus to create your bootable Kali USB. You can download it here: rufus.akeo.ie . When prompted, select ‘DD Image Mode’. Using ‘ISO Image Mode’ will not work!!
Step 2: Detect and Mount CD-ROM
a. When you get to this point where it says ‘your installation CD-Rom couldn’t be mounted, unplug the USB from your computer drive and wait 30 seconds before plugging it back in, b. After plugging the USB back into the drive, wait another 30 seconds then click ‘yes’ to retry mounting the CD-ROM
Step 3: Missing Firmware
During installation you may get a message that indicates you’re missing firmware or some other package, I typically just ignore them and continue on with the installation. I’ve never had any issues. But if you’re insist…. When you get to the part where it notifies you that you’re missing firmware, visit the following link and download it onto a different USB device. packages.debian.org/wheezy/all/firmware-realtek/download. (Kali Linux is based on Debian Wheezy)
Choose which ever mirror closest to you
Step 4: Install Missing Firmware
Insert the USB you just downloaded the missing firmware onto into the computer you’re installing Kali on. Wait 30 seconds before clicking ‘yes’ to install the firmware from a removable device.
