Create Partition for RouterOS Installation

I install RouterOS from Boot CD and It format the whole Hard Disk. I’m looking for a way to install on a partition. Because I don’t think that it would take the whole HD space for just a very quick RouterOS installation. Is there any tool which will help to solve this problem?

The hard disk will be entirely reformatted during the installation and all data on it will be lost!

No, you can not install routeros to a partition.

Cheers.

What kind of partition that store RouterOS? (Ext, Ext2, …) Why it take the whole hard disk space since the installation CD is only 20Mb. Why it take a lot of space since it doesn’t need? Is there any advanced technique to install RouterOS on a limit space. I glad to hear from you even if it is a complex method.
