The No ROM basic system halted error can be confusing, but generally means there are no bootable devices or ROM (read-only memory). The error can happen if there is no active partition defined in fdisk, hard drive not set up properly, corrupt MBR (master boot record), or the hard drive is bad.

Trying to boot from non-bootable media

If you are attempting to boot from the hard drive, make sure no floppy diskettes, CDs (compact disc), USB (universal serial bus) drives are in or connected to the computer. The computer may be attempting to boot from one of these and is causing the error.

Create active partition

After setting up your hard drive through fdisk, you may receive the error message "No ROM basic system halted." This error indicates the hard drive's active partition is not set correctly. To resolve the issue, boot from a bootable diskette and enter fdisk. Within fdisk, choose option 2 to set active partition and set the drive you want to be bootable as the active partition.

Verify hard drive properly set up in CMOS

Verify that the hard drive is properly set up in CMOS setup. If no hard drive is seen continue with the next steps.

Check cables

If creating an active partition does not resolve your issue or fdisk does not detect a hard drive, verify that the hard drive cables are connected correctly.

Replace drive

Finally, if none of the above solutions resolve this error, unfortunately the hard drive is most likely bad. We recommend contacting the manufacturer of the hard drive to have it replaced or purchasing a new hard drive.
