Insert this hard drive/CF card into the final router hardware. Summary Checklist for Troubleshooting Primary Solution Change CD-ROM controller from SCSI/SATA to IDE . Physical PC Switch BIOS to Legacy/CSM Mode . Physical/Virtual Use Install Image (.img) + physdiskwrite instead of ISO. All Ensure the ISO/Image is not corrupted (verify MD5). fatal error no cd rom found mikrotik full

Change the SATA controller mode from to IDE or Compatibility mode. This trick often allows the installer to "see" the drive as a standard IDE CD-ROM. 2. Use the "Install Image" Instead of the ISO If you are installing via USB, do not use the ISO. Instead:

Boot your device into "Etherboot" mode (usually by holding the Reset button while powering on). Map SATA Mode to IDE 2

RouterOS is picky about how it is "burned" to a flash drive. Do not simply copy-paste the file. Use a tool like or Rufus .

Sometimes the partition table is corrupted, making the disk look like a "non-disk" to the installer. Direct dd to Target Disk 1

Ensure the CD/DVD drive is set to IDE . If it is set to SCSI, the installer often fails to find it. VirtualBox: Use the PIIX4 controller for the storage tree. Connection at Power On

This is one of the most common hurdles when moving from standard Linux distributions to MikroTik’s proprietary installation environment. It usually happens when the installer cannot locate the installation media it expects, or when the underlying hardware detection fails.

Despite the seeming contradiction, burning the RouterOS ISO to an actual CD or DVD rather than using USB media sometimes resolves the issue.

The most straightforward fix is adjusting how your motherboard handles storage: Enter your BIOS/UEFI settings. Disable and switch to Legacy or CSM mode.
