Svan,
Perhaps Linux is not for you. If you don't want to learn something new, why are you using something you are unfamiliar with? Linux and UNIX are not "Windows but free" they are different tools with different paradigms for doing things.
GRUB is a boot loader and a more effective and powerful one than ntldr is. You CAN boot with ntldr for your needs and here's a link on how:

Cool Solutions: Configuring Dual Boot (SUSE Linux, Windows) Systems
You may have to make adjustments as this is for SUSE and you are using Red Hat or a clone of it.
However, you can install grub (and it is recommended that you do so). I would recommend you load it on your first drive and use it to boot both operating systems instead of trying to make Windows, already unfriendly to other systems, boot Linux for you.
As well, you should understand that C: and D: and such are Windows/Dos constructs. In linux, you have no "drives" per se, they are all files. Everything is considered a file in *Nix. Thus, your disk drives are /dev/sda (for serial drive a, including SCSI and SATA/SAS drives). /dev/hda and hdb and hdc and such are PATA/IDE drives. The number after them, when in the OS (Not the boot loader, GRUB) are the partition.
Each drive can contain 4 primary partitions at most, or, you can form the last primary partition into an extended partition, "using up" the last primary partition to create a space to create extended partitions. This way you can usually have ~16 partitions per drive.
This way, /dev/sda is the drive and /dev/sda1 is the first partition (primary)
/dev/sda2 and /dev/sda3 are the 2nd and third partitions. /dev/sda4 would be the last primary, but it is usually not allocated that way and instead becomes a container for extended partitions and you would go directly to /dev/sda5 and so forth.
After you partition, and you should learn about how to do that and why, you need to create a file system (Windows usually has 2-3 options of FAT, FAT32 and NTFS, though a few others are not often used), however Linux can use multiple ones including FAT/VFAT(Fat32 implemented on Linux) and Ext2/3/4, ReiserFS (dead, no pun intended), XFS, JFS, etc etc. They have merits to them all.
Again, if you choose to learn about this, you will have a more pleasant experience using the operating system than if you just choose to butt heads with it and complain about it.
