You’ve been working on your NAS disks, or maybe you’ve been mucking around in your computer’s BIOS. You reboot your computer, and you get the message: “This is a NAS data disk and cannot boot system. System halted.” At this point, you’re not sure what to do. When did your system start thinking that the NAS data storage had something to do with booting? Have you done something wrong with your BIOS? Do you need to perform a NAS recovery? And why can’t you boot your system?
The Network Attached Storage Disk or NAS Array
The Network Attached Storage Array, or NAS array, is a type of storage system that is connected to the network and accessed by different computers. It is never intended to be a boot disk; instead, it has its own operating system (usually an altered version of Linux). The disks themselves are managed through the NAS cabinet.
Because a data NAS is used for data, it can’t house your operating system. Pulling out a NAS disk and hooking it up to your computer, Linux or not, isn’t a good idea, because the NAS cabinet handles the data and controls how the disk (or disks) have been arranged. If you are using a NAS disk and you have a Microsoft computer, chances are your computer won’t even recognize any of the data on the disk at all.
A Cryptic Message, but a Simple Problem for Your NAS Data Storage Device
The good news is that your boot error probably isn’t a huge problem. Although the message is somewhat cryptic, the situation is certainly easily remedied. One of two things may have happened. The first is if you’ve been working in the computer’s BIOS and changed the boot order (intentionally or inadvertently). When your computer says, “This is a NAS data disk and cannot boot system. System halted,” what is is really saying that you’re trying to boot the wrong disk–in this case, the NAS array–and it’s smart enough to know it can’t boot from it. Go back into the BIOS and change the boot order to your boot disk. That will solve the problem.
“This is a NAS data disk and cannot boot system”
The other potential cause is that you’re trying to intentionally use your NAS data storage as a boot disk, either by removing one of the disks and placing it in the boot drive’s slot, or by trying to create a bootable sector on the NAS data storage device which you’re planning to install your computer’s operating system to. Neither will work, so it’s important to keep your boot disk and point your computer’s BIOS to the correct hard disk drive.
NAS Recovery: But What if I Haven’t Changed the BIOS?
You can also get the “This is a NAS data disk and cannot boot system. System halted” message if the BIOS becomes confused over the boot order of devices connected to your computer. This can happen, oddly enough, when you move your system and the boot order gets rearranged. You can modify the BIOS, or if you remove all disks except the book disk and reboot, your computer may reshuffle the disks and you’ll be able to boot and add the NAS later. This depends on your system and how much elbow grease you feel like putting in. Just make sure the boot order is correct, and you’re likely to have few problems booting your computer.
In some rare instances, though, the error is the result of a boot disk failure. In this case, your BIOS is going down the line of the disks and has hit on your NAS array as the next best thing to boot from (it isn’t). So, you need a new boot disk. If you have any important data on the failed hard disk drive and you don’t have up-to-date backups readily available to restore from, you will need to call upon data recovery experts.
