This must be off for the RouterOS kernel to load correctly. 2. Use Netinstall (The Recommended Method)

: Temporarily connect the target hard drive to a different PC, install RouterOS using Netinstall , and then move the drive back to the original machine. Comparison of Installation Methods "FATAL ERROR: no CD-ROM found" during installation fatal error no cd rom found mikrotik

and a USB 2.0 drive. Modern USB 3.0 controllers sometimes lack drivers in the older RouterOS installer kernel. Re-create Boot Media Netinstall (Recommended) : Instead of an ISO, use the MikroTik Netinstall utility to write RouterOS directly to your target drive. : If on Linux or macOS, use the command to write the ISO to the USB drive as a raw image. Hardware Compatibility SATA vs. IDE This must be off for the RouterOS kernel to load correctly

This error typically stems from a mismatch between the RouterOS installer's limited driver set and your hardware configuration: Comparison of Installation Methods "FATAL ERROR: no CD-ROM

The MikroTik ISO kernel was compiled with drivers for legacy IDE CD-ROMs ( /dev/hdc or /dev/sr0 ). If your USB stick presents itself as a "USB Mass Storage Device" (SCSI emulation), the kernel's init script doesn't know where to mount the installation files. It searches for cdrom and fails.

Before diving into theory, here is the fastest way to bypass the error.

Use Netinstall . If Netinstall fails (no driver for your NIC), install a supported Intel PRO/1000 PCIe NIC temporarily.
