Ubuntu Installation and Partitions

To Whom It May Concern,

I have noticed that during the installation of Ubuntu 10.04 (Lucid) that there is the possibility to create partitions of a logical drive and mount these partitions at various mount points such as / ,/ext , /boot etc.

The logical partition is created from a raid 6 array of 4. disks. On the subsequent logical drive, if I were to install Ubuntu 10.04 in one partition, say /boot and the software in another mounted partition, say /software with the data in another mounted partition say /data.

If the Ubuntu O/S somehow becomes corrupt and I need to re - install it would I be able to simply format the /boot logical partition and re - install it on the /boot partion while preserving the data present on the other mounted logical partions such as /software and /data?

Thanks
Vaughan
