Installing Windows & Linux on new T105

[Timothy Murphy]

The PowerEdge T105 I bought just arrived,
and I've been looking at the contents of the first disk with Knoppix.
The system was bought without operating system,
but I have installed a copy of Windows XP to look at the system.
I would like to install Windows and Fedora Linux.

The first had 3 partitions originally:
/dev/sda1 50MB,
/dev/sda2 2GB
/dev/sda3 Extended partition, the rest of the 80GB disk

As far as I can see, the first partition contains Dell utilities.
I assume that it is intended for some kind of repair or rescue?
Under Windows this first partition is not listed in My Computer 

The second partition seems to be a kind of vestigial operating system.
Windows describes it as "OS (C:)".
It contains files (or directories) System Vol, AUTOEXEC,
boot.ini, bootsect,dos, CONFIG.SYS, IO.SYS, MSDOS.SYS,
NTDETECT, ntdir, pagefile.scp .

Windows was installed on /dev/sda5, or LOCAL DISK (E:) according to Windows.

I want to know if I can safely delete /dev/sda2
or else copy it to the second 250GB disk?
Could I also move /dev/sda1 to the second disk?
Or must it remain where it is?

Assuming /dev/sda1 must remain where it is,
I would like to delete /dev/sda2 and /dev/sda3,
and create 30GB Windows partition at /dev/sda2,
100MB Linux /boot partition at /dev/sda3,
and 30GB Linux / at /dev/sda5 .

Can I do that?
In particular can I safely delete of copy /dev/sda2?

Any suggestions or advice gratefully received.
