How to have Linux and Windows on the same machine

I am having a tough time installing Linux and doing the dual boot.

Here is what I have:

I have 80GB hard drive as my Master drive with Windows 2000 Prof. with NTFS File system.

I brought a 250GB hard drive and set it up as Slave.
I have RedHat Linux ES 2.1

I have used various combinations of GRUB/LILO and installing the boot loader in the MBR/First Sector.

Every time I boot my system it is going to linux and it doesn't list the windows.
To boot into windows I am using a windows boot diskette.

What do I have to do to dual boot into any of the operating systems.

I'm suprised RH didn't detect windows and write the config file for you.
For either lilo or grub, there are many, many posts on LQ about how to set up lilo.conf or grub.conf to correctly display the boot menu. Just search on the term 'dual boot'.
To get it working, boot into RH and edit /boot/grub/grub.conf (or lilo.conf, wherever it's located, then run /sbin/lilo). You will need to add a menu entry with boot parameters for the windows partition.
You should also check /etc/fstab to be certain that the windows partition is listed.

I am able to dual boot now by changing the grub.conf file and adding a windows entry.

But there is one more problem.

I have installed Linux on 250 GB hard drive(Slave) and it is not recognising 104 GB and only 130+.

I can see 104 GB as unallocated from windows-disk Management.

Can anyone please tell me how to use this 104 GB in Linux.

Go into BIOS when you turn the computer on and see how big the drive is if it displays 130Gb for the drive then you can't utilise that extra space. The motherboard manufacturer may have since released an update for the BIOS so that the motherboard will recognise bigger drives. If this is the case then you'll need to flash the BIOS, but be warned flashing the BIOS is not something to be taken on lightly, if it goes wrong you'll render the motherboard useless

EDIT: Whether or not your motherboard will support bigger drives doesn't necessarily depend on how modern it is, I have built computers in the last few months where they will only recognise 130Gb of a 160Gb hard drive, yet I've an ASUS and a Gateway (manufatcured by Intel for gateway to distribute) that are both around 4 or 5 years old and both recognise 160Gb hard drives

Thanks for the update, But Windows is able to see so I am guessing it is not a BIOS issue.
