MikroTik provides , a tool that sends the RouterOS image via Ethernet (PXE-like). This also bypasses the CD-ROM error because it does not use optical media.
When you boot from the MikroTik ISO image, the installer loads a small Linux-based kernel to handle the installation onto your hard drive. If this kernel cannot locate the source media (the virtual or physical CD-ROM drive) after loading, it stops and displays the fatal error. This usually happens because:
The error is a ghost of computing past—a legacy kernel expecting an IDE CD-ROM in a world of NVMe and AHCI. You now have three complete solutions: fatal error no cd rom found mikrotik full

Add an empty optical drive to the IDE Controller, then mount your RouterOS ISO file to it. For Proxmox VE Select your RouterOS VM and go to the tab. If this kernel cannot locate the source media
When SATA controllers are set to AHCI mode in BIOS, RouterOS may not recognize the CD-ROM drive.
The standalone x86 installer for RouterOS relies on legacy Linux kernel baselines. Modern AHCI, SATA, or NVMe storage configurations often cannot be read natively by older installation environments during the secondary boot stage.
Use tools like Rufus to burn the ISO file. Ensure the partition scheme is set to MBR and the target system is BIOS (or UEFI-CSM) .
