dual boot 2 hds?


I have two hard drives, one is pretty old ( I think you call them ATA drives, the kind with the largish "bus" cables ) 15gb, and the other is a new 80 gb samsumg SATA i think with two easy small connectors.

Now I have Win XP on the 80 gb, and I've installed Redhat 9 on the 15gb ( couldn't get my hands on FedC4 ).

Everything seems to be find with both, except that neither know the other hd exists.

To boot into the OS that I want I go to BIOS and then select the Primary HD and walah.

While installing Redhat, it didn't detect the other HD, so I couldn't configure GRUB to have a choice.

I'm new to this.Can you tell me what to do so that both are detected.

And also if I can ( after detection ) configure GRUB to give me an option for which OS to boot into?

Thanks.

P.S. Very slow,detailed, braindead answers will help.I'm a complete newbie.

And also...is it just NOT possible because of the different types of hard drives?

Don't worry I'm a newb too, but I think I may be able to help.

The problem definitely doesn't lie in the drives themselves. I am a hardware tech, with (some) experience in linux and a decent amount of experience in (horror)windows and can tell you that right off the bat.

As for them not detecting each other, I am not exactly sure try this command in your shell in Linux.

mount /dev/my_drive /mnt/my_mount_point

If your Win. Hard drive is set as master, the drive designation should either be hda1(for your main partition) or consecutive numbers if you have multiple partitions. It could also be /dev/hdc1 if neither of these work tell me.

If that works with no errors, you can go to the directory /mnt/hd_whatever, and you should see everything in your drive.

I'm not sure about Windows(having never dual booted them myself) but thanks to the complete ineptness of it's programmers, it may not be able to see the Linux partition at all. You may be able to get a program that will allow you to see it, though.

If none of these work, check and make sure your drives are set properly as master(because they are on different cables).

Hope this helps!

Edit: One more thing - you can try making sure Lilo is installed in the MBR, not at the beginning of the partition. Not sure how to do that in Windows or even whether you can or not but you can look.

thanks for the advice, will try...a litle more help please...any software that I can load on windows to achieve dual boot ( instead of using GRUB ).

Also my perfectly fine onboard sound ( ' soundcard not detected ' ) doesn't work on linux, help for a newbie please ( bambii eyes ).

heheh.


Oh and this is all for Redhat 9.

P.S., can anyone possibly mail me Fedora Core 4 or 3?I mean snail mail.Highly unlikely...but it'd be a very good deed when they ask you at the pearly gates.

You Linux hard drive may not see your windows (SATA) hard drive since SATA hard drives are newer hardware. As far as I know, RH 9 (the default kernel on RH 9) does not have support for SATA drives. You can either compile a newer kernel (which I think would be a drag considering RH 9 is now unsupported and discontinued) or migrate to a newer distro. If you are comfortable with RH 9 you have the option of Fedora Core or CentOS or any other RedHat based distro.

Edit: You can easily install grub or lilo and dual boot but you won't be able to mount your windows disc in Linux (as I said, unsupported hardware).

Tux,

Hmmm... just a thought... Don't forget the partition-table! It may be that the drive is "seen" .. (see /proc/devices or /sys to determine what devices are there) .. but none of the partition-types are identified as ones that ought to be mounted. For example, absent any Installable File System (IFS) drivers, Windows will ignore (say) an 'ext2' filesystem. It will ignore a 'Linux swap' partition.

As for dual-booting, there are two reasonable options:
  1. Actually switch the BIOS boot-drive designation. That "always works."
  2. Have the system initially boot up to Grub, and within the /boot/grub/grub.conf file, specify an option that will boot Windows, from its drive. (Grub will actually load NTLDR.EXE and transfer to it just as the BIOS would have done.)
