Error Linux o.s on two sata's.


I have two sata hard-disks. Out of those, one is having RHEL5 operating system, and other is having fedora7 operating system.
When I connect the disk with RHEL5 operating system to sata0 port and disk with fedora7 operating system to sata1 port. While booting [after POST] it shows RHEL5 boot screen[red colour screen , which appear while booting of RHEL5], But surprisingly it mounts/boots into other OS i.e fedora7 operating system.
I am not able to understand.Hw will it boot? if we connect two linux OS on two different sata H/D's?

Thanks in advance.

It'll be your /etc/fstab settings I'd say. You are probably accidentally telling it you have the fielsystems on the other disk (if you have moved their positions on the ATA bus that would be expected)

The senario is :[ If I connect individual disks ]

Sata 1 disk : RHEL5 with / ,/boot , /home,, partitions
/dev/sda2 /
/dev/sda1 /boot
tmpfs /dev/shm
/dev/sda3 /home

Sata 2 disk : Fedora with / , /home,/u01,,,, partitions
/dev/sda1 /
/dev/sda2 /home
tmpfs /dev/shm
/dev/sda3 /u01

The scenario is : [ sata disk2(Fedora) is connected to sataPort0 on motherboard and sata disk1(RHEL5) is connected to sataPort1 on motherboard]

/dev/sdb2 /
/dev/sdb1 /boot
tmpfs /dev/shm
/dev/sda2 /home

Quest 1:How will it boot If I connect both the H/D's as I mentioned above.?
Quest 2:How is it mounting the partitions from different H/D's?
