Can window server 2003 be set dual boot with Linux red hat?? I am refering to current red hat version.

I don't have either OS installed, but I do know that XP and Fedora Core boot together perfectly. That's because Fedora Core (made by Redhat too) has a bootloader app preinstalled that allows you to choose which OS to load. That way, you can boot XP, 2003, Vista, 5 copies of linux lol. Whatetever-t-f you want to boot. I'll almost guarantee you that your Redhat will dual-boot with 2003 just fine.

Wrong forum, but the answer is yes.

You will need a partitioned hard drive or two hard drives.
If using just one hard drive.

During W2003 installation, delete any partitions, then create two partitions and format one, dont format the other partition. Install and configure 2003.

Once you are done with that, boot off the Red Hat CD/DVD and anaconda will take of everything. It will recognize the windows partion and install on the unformatted partition.

When you reboot, the GRUB bootloader will give you the option of boot to Linux or 'other'

For testing purpose...yes. But install both in their own hard drives. You shouldn't mix file systems for both those OS'...and preferably, you should keep their native boot loaders...meaning you run them (or install) with only one drive active at a time.

In a production environment...not a chance.
