I want ONLY 1 operating hdd on this computer. I want to disconnect the 2nd hdd, but leave it in the case so that I may occasionally hook it up and add / delete data to / from it (2nd hdd is NTFS and only for data storage). What should I do?
Here is the problem:
When I disconnect the 2nd hdd (I don't need it, so I disconnected both its IDE cable and power cable) and boot, BIOS fails to detect either hdd.
In other words, I can not finish booting because when I disconnect the 2nd hdd, the 1st hdd (with Linux on it) is not found, although strangely both optical units (1 dvd player, 1 cd burner) are found. My hdds are primary master / slave and my optical units are secondary master / slave.
Specifically, after I disconnect the 2nd hdd and boot, I get the message: >>>Insert boot disc and press enter<<<
The only way to resolve this is to reconnect both the IDE and power cables to the 2nd hdd. Then it works fine.

Here are some basic background facts (note this is not my computer, so I might not know all of the background data):
1) Linux MEPIS 3.43
2) KDE 3.5 something
3) ATI card
4) ASUS mobo (I think)
5) HDD master / slave is properly set
6) Optical drive master / slave is properly set
7) GRUB installed on MBR 1st sector
8) I already went into BIOS and set the 2nd hdd to "none" and I still had the same problem
what I am assuming here is your hdd is detected and the problem here is that the bootloader doesnt popup.
what you could do here is, boot with the installation disk and go to the rescue mode, by typing linux rescue. then reinstall grub. grub-install /dev/hdxx. that should do the work for ya.

Maybe, I don't know. I do know this though: When I start up (i.e., boot), BIOS lists "none" for both hdds, but lists everything else just find.
Should I proceed as you recommended, or does that extra bit of info change things?
Also...I will look into that "single" hdd setting as someone else mentioned.
You using master/slave jumpers on the disks, or cable-select ???.
Try a bit of problem isolation - remove the second disk, move the remaining disk to its (interface) connector.
Does it show up in the BIOS, does it boot ... ???
If so, stick the other one back on the (now) spare connector.
All good ??? - if not,keep looking.
This computer is for my mom, who is even more computer illiterate than most people. So, any option that *avoids* command line use on a regular basis would be most ideal.
your problem here is, your hdd isnt being detected first solve that problem as syg00 and Emerson suggested, after you solve that check if the boot loader doesnt appear.
moreover if you want to have only one OS and that too linux whats the problem in overwriting the MBR

**you *must* install grub on the hd if Linux is to be your only OS.

dont get your point here? you want linux and dont want linux ...blah I dont understand?
Since hda1 is my root partition of my primary hdd, is that what I would replace hdxx with?
In other words, should it look like this: /dev/hda1
Is that correct?
If that works, then would my boot into Linux change in any significant way (i.e., require lots of command prompt stuff, etc)
/ n00b, so play nice if I ask dumb questions
// unrelated note, I've got a printer question in the hardware forum...if any of you have experience with that I would appreciate your input as well. Thanks!
If you install it to hda1 then you need another bootloader on MBR to chainload GRUB.
Emerson...I do not understand what you mean.
Let me try to interpret: If I want grub on hda1 then I must also install grub on mbr. Correct?
I already have grub on mbr so if I understood you correctly, does that mean I must have it installed on hda1 too? In other words, install grub twice...once in mbr and once in hda1? If I do that, then I should be able to boot without any funky command line stuff?
Normally BIOS executes the code on MBR and the code on MBR loads OS (simplified). This means you need to install GRUB to hda (not hda1). In case you install GRUB on partition (hda1) BIOS does not find it and computer won't boot - unless there is another bootloader on MBR which can load GRUB from partition. This another bootloader may be anything, ntloader for instance or GAG or something else.
