Bob, first off you really shouldn't have switched the cabling around because you just invalidated all the source drive and partition output you provided earlier. Makes things much messier.

There's a couple of different approaches you can take:

1. Modify the Windows BCD (boot) partition to point to your Linux install. I think it picks up XP installs automatically, but that's easy enough to verify. If not you will have to add an entry for XP as well. This could be accomplished by using something like EasyBCD.

2. Simply put grub on sda as the previous poster has suggested and add entries for XP & Windows 7.

You were right to think the sd naming conventions are related to how the drives are attached to the board. There is a direct relation.

i.e. Presuming your initial drive lettering (before you swapped cables):

sda = hd 0 The first physical drive on your motherboard, remember: this correlates to the FIRST drive on the primary IDE (or SATA) channel.

sdb = hd 1 The second physical drive on the primary IDE (or SATA) channel) The numbers listed after the device names represent the specific partitions. e.g. sdb1 = first partition on second drive.

sdc = hd 2 The third physical drive, the first drive on secondary IDE channel in your case.

sdd = hd 3 The fourth physical drive, the second drive on secondary IDE channel.

If you're still having trouble, please re-verify ALL drive information and include your BIOS boot order as it currently stands. Finally, in answer to your question as to why Windows 7 is sitting out there by its lonesome on sdc, it's because that is the where the BCD boot loader partition resides. That boot partition points to sdb1 to boot Windows 7, and sdb2 to boot Windows XP.

To sum up, you could fix it by doing the following:

1. Switch the cables back to how they were.
2. Use EasyBCD to modify Windows 7's BCD partition (which resides on sdc) and add Linux (which resides on sdb6) to the boot selections

OR

3. Add change boot order (assuming you swapped things back) so system boots to grub, then add entries in Grub to boot to XP & 7 which reside on sdb1 & sdb2 respectively.

Hope this helps, cheers.

I did the steps in your post 4 again, but the system is still booting on windows 7 immediately, without going through grub.

Hell the more I look at it man, if you look at grub.conf in your previous posts it already has entries for Windows in it. Just change your cabling back to how it was, then modify boot order to boot to the drive you had Grub on. (originally it was sdb/hd1). Done!

But you just told us that you were "at the grub prompt" (post12)
Have you changed the drive order again ?

Brocifer you're right at some point I had grub working, and it detected everything (all 3 OSes). This was good, but I wasn't satisfied by the names the devices were given (particularly, the fact that sda wasn't the device where the OSes were). Plus, there were some other issues yet to be solved, such as the fact that the windows 7 loader was not on the same device as windows 7 itself, which could I guess lead to some problems if that auxiliary device were to be removed.
That's why I chose to change the wires. The configuration might be more difficult to get working, but at least we're on a good base now, since the devices are now named the way I want. All we have to do now is to make grub start when the computer starts.

On an unrelated note, but for clarification, let me state that I have made two wire switches. When I started the thread, grub didn't start (windows 7 was booting automatically). So I changed sdc and sdb (and did the steps described in #4). Then grub worked. Then I switched the wires again (sdc->sda, sdb->sdc, sdd->sdb, sda->sdd), to make sda the device where the 3 OSes are.

Bob, again the Windows 7 loader is on a different partition by design, there's nothing wrong with that per se. It can be moved if you want to blow away that third drive eventually, but worry about that later. For now, things are completely gummed up. Until you can re-verify the drive lettering and boot order in BIOS this is going to be difficult to solve. I can't stress this enough, stop switching drive cables around and ONLY modify the boot order in BIOS to achieve initial booting to different devices. You'll end up spending the rest of your weekend chasing your tail if you don't.

okay brocifer, I'm sorry to make things difficult, in the end I'm just a newbie so I'll stop messing around and I'll do exclusively what you tell me to from now on.
I would just like to state what I want, and then I'll follow your instructions to achieve that goal: I want the 250GB hard drive to contain the 3 OS and everything that is needed for them to run and to be chosen from (grub, windows loaders if they are necessary...), and I would rather it to appear as 'sda'. The 3 other devices are just data hard drives and are likely to be moved (I sometimes lend them, etc) so they are not to contain anything that is relative to the system.
So at the moment, the 250GB disk appears as sda, but grub doesn't start, windows 7 launches immediately.
Please let me know what to do, including moving the wires the way they were if necessary.

Thanks a lot for your help so far.

In post #11 I asked if there was anything in your BIOS about the boot order. Please answer that question before we do anything else, because grub needs to installed to the MBR of the drive your computer is choosing to be the first HDD in the boot order.

No problem sir, I think we can get you fixed up but we need to establish a base line first. What I would recommend then is the following:

1. Since you want the big drive to be sda, plug the 250G in on the primary channel (I'm assuming these are IDE drives?) If they're sata, just make sure you swap it to sata channel 0.

2. Ensure the boot order in BIOS points to that drive.

3. Repost the output of bootinfo so we can double check which 2G drive the Win 7 BCD got written to (we'll need that to fix Grub's Win 7 entry)

Your system should now try to boot to the original grub conf, which is now broken since we've switched drives. You need to modify the grub to point to sda now instead of sdb. Once you've done that you should be able to boot into linux w/ the drive as sda.

The other three can be plugged in in whatever order you want, but you must include the 2G drive Win7's BCD got written to. Once you've done that, please repost the new bootinfo output and we should be able to get things crackin'.

Sorry, please re-read my last post. Edited for clarity, as I remembered we'll need to tweak original grub conf as well once you've switched the 250G to be sda or Linux won't boot either.

Tregedar (and Brocifer),
I don't see anything in the bios that says anything specific to the boot order of the hard drives, but then again I'm not an expert.
All I see is the boot order that is relative to the type of device (usb stick first, then optical drive, then hard drive, ...). But I'm not 100% sure, maybe I'm just not looking in the right place. I could list all the menu entries if you want (?).

Brocifer,
The drives are sata, not ide. The 250GB hard drive (the one containing the 3 OS) is indeed plugged in SATAII0. For practical reasons, (the sata wire is bent at an angle (http://img.alibaba.com/photo/3657795...SATA_Cable.jpg), SATAII1 is not used. If you want (?) I can state which channel the other 3 devices are plugged into.

All I see is the boot order that is relative to the type of device (usb stick first, then optical drive, then hard drive, ...). But I'm not 100% sure, maybe I'm just not looking in the right place. I could list all the menu entries if you want (?).

Brocifer,
The drives are sata, not ide. The 250GB hard drive (the one containing the 3 OS) is indeed plugged in SATAII0. For practical reasons, (the sata wire is bent at an angle (http://img.alibaba.com/photo/3657795...SATA_Cable.jpg), SATAII1 is not used. If you want (?) I can state which channel the other 3 devices are plugged into.

The output of the boot info script is:
Boot Info Script 0.55 dated February 15th, 2010

============================= Boot Info Summary: ==============================

=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #6 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb
=> Windows is installed in the MBR of /dev/sdc
=> Windows is installed in the MBR of /dev/sdd
...
Please make the following changes to grub.conf and let me know if any OS's are/are not booting properly:

### BEGIN /etc/grub.d/10_linux ###

It's located in /boot/grub.

To modify it, you'll need to boot to your livecd for your distro and select maintenance mode. Once you're in maintenance mode, try the following:

Code:
mount -o remount,rw /
then

Code:
cat /boot/grub/grub.conf | sed s/hd1/hd0/g
Then reboot and test it out.
