I would start with a grub floppy disk or boot CD(-RW) and look what Both drives are bootable provided I make a detour to the BIOS and change the boot order. Somehow I suspect that the BIOS gets something wrong when you change the boot order. But that's just a suspicion. So my suggestion was to change it to default (first HD first). Then check from a grub running from floppy or CDRW what that can see. So you can try if my suspicion is wrong, what might well be the case: That grub (from floppy or CD) will only see one drive, too, if I'm wrong. Otherwise you know that I was probably right and your only option then is to leave the BIOS boot order untouched. devices that sees when booting. In order to have grub list disks, you dmesg reports ALL drives and appropriate partitions. But that is what _Linux_ sees. Linux has its own drivers, working completely independent from what the BIOS was doing before -- and that's what a grub (at boot stage) has to rely on. So Linux' output only tells us that generally: - your drives are OK, the cabling too. - your controllers are working. But we need to make sure the BIOS initializes everything right. It might not do so if boot order is changed (and from a certain point of view, that might actually be a feature). enter root ( and press TAB.

Isn't it supposed to be bootable? Oh, the Windows MBR is just giving control to the boot block of the partition holding Windows, which itself then stages ntldr. So when I said it'll make it unbootable, I was talking about the Windows MBR. Grub should run anyway nevertheless, and then it should be able to give control to the Windows partition boot block -- but I was just giving a warning that what definately happens is that the Windows MBR is gone.

Error 21 even though the boot routine is identical to the one that WORKS when the second drive is given boot preference. Personally, I don't see much difference, this approach shares similar problems. Apropos problem, error 21 is Selected disk does not exist. I think it might have happened because you probably switched drive order again when doing the Linux based steps descibed in the link you've give. When the MBR is written, it stores references to the stage files. They might point to an invalid location if you change the boot order back again. That's what I think why you're seeing this error. Grub can perfectly from a floppy disk. See info grub (the full grub documentation, the man page is crap) in order to learn how to create a grub floppy disk (or CD/R(W)). You will then be able to set the BIOS boot order to default and see what a freshly booted grub sees then. From within the grub booted this way, you can order grub to setup itself to an MBR or boot block. Basically, you have to set root, then issue setup. The first takes the device of the stage files as argument, the latter the target disk (or partition).

Re: [gentoo-user] grub hell
I came to this late and missed most of the thread so apologies if this has been covered. Did you mount /proc into /mnt/gentoo before chroot'ing? (see install docs) This allows grub to correctly sense the drive map for writing the boot sectors. Some early MB's changed the drive map depending on what disk/media (i.e., cdrom) you booted from so grub wrote a correct map at the time, then the MB changed the mapping on the HD boot. Fix was to intelligently guess the correct drive and write it manually using grub. A later bios update allowed some control at the bios level which made it easier.

I am not sure if you have tried this or not, but when you map one drive to
another {say: map (hd0) (hd1)}, you also need to map the second drive to the
first, instead of leaving it hanging. So, the complete entry becomes:
map (hd0) (hd1)
map (hd1) (hd0)
If this doesn't work you may want to try the hide command. Hide all the other
bootable partitions but the one you intend to boot:
unhide (hd1,0)
hide (hd1,0)
rootnoverify (hd1,0)
map (hd0) (hd1) --These two may or may not be
map (hd1) (hd0) --needed with un/hide command

It is also a good idea to only have the bootable flag set with fdisk on the

Are you sure you're selecting the correct disk? Don't just assume
since it's hdc in Linux it's hd2, use tab-completion when you're
setting up grub., Have you tried using grub console
w/tab-completion? Hit 'c' when you're booted to grub, and try
grub root (hd{hit tab to see what's there}
It's all the same syntax as grub.conf
I've tried changing the boot order in the BIOS.
I can get gentoo to boot if I tell grub it's on (hd0,0)(?!?!) but
WinXP won't boot unless I remove the HD w/gentoo on it and bypass
grub altogether.
Where is grub installed currently? The easiest way I've gotten it to
work is to install over Window's MBR and use a chainloader +1 line to
chainload windows.
Lastly What partitions are marked as active/bootable? I assume the xp
one is (hda), but what about hdc when you're trying to install grub
there? Also, I don't _think_ you can have more than 1 active/bootable
disk.
fdisk can see both drives OK. Both drives appear in dmesg w/o
errors. Both drives appear in the POST screen -- first drive as
'0', second drive as '1'
Again, this leads me to believe that grub is seeing the second disk as
hd1. Granted; you never said what you called it but that might be your
problem.

My guess is that you have incompatible jumper settings on the back of the drives. Check these and make sure that they reflect what the BIOS sees. Also, check your /boot/grub/device.map for consistency. Then use tab completion from the grub prompt to find devices and bootable partitions. Both drives are set to master which the BIOS confirms. Device map: (fd0) /dev/fd0 (hd0) /dev/hda (hd1) /dev/hdc is consistent. Tab completion at the grub prompt only finds the second drive which it insists on calling the first contrary to device.map. If the above doesn't get you booting please post your grub.conf, along with fdisk -l. grub.conf: #XP title=XP rootnoverify (hd0,0) map (hd1)(hd0) makeactive chainloader +1 boot (I used one 'map' command following Dan Farrell's model but using two made no difference) #Gentoo title=Gentoo root (hd0,0) kernel /vmlinuz root=/dev/hdc3 video=aty128fb:[EMAIL PROTECTED] boot Note: The entry for XP elicits: Error 11 Unrecognized device string no matter how I edit it using the 'e' command in grub. Gentoo will not boot unless grub is told it's on the FIRST drive contrary to device.map anything else and grub reports disk does not exist fdisk -l: Disk /dev/hda: 6448 MB, 6448619520 bytes 255 heads, 63 sectors/track, 784 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 783 62894167 HPFS/NTFS Disk /dev/hdc: 122.9 GB, 122942324736 bytes 176 heads, 63 sectors/track, 21656 cylinders Units = cylinders of 11088 * 512 = 5677056 bytes Device Boot Start End Blocks Id System /dev/hdc1 * 1 7 38776+ 83 Linux /dev/hdc2 8 96 493416 82 Linux swap / Solaris /dev/hdc3 97 1066658600080 83 Linux /dev/hdc4 10667 2165660928560 83 Linux I've tried toggling the bootable flag on /dev/hda. Didn't work. As I mentioned before attempts to install grub to /dev/hda fail completely forcing a reboot w/Win98 and entering A:\fdisk /mbr after which XP boots but only if the second drive is disabled. Installing to /dev/hdc at least lets me boot gentoo. Both drives pass smartctl tests. grub is version 0.97 Don't know what else to add. -mw __ Do You Yahoo!? Tired of spam? Yahoo!

In your grub.conf, you say the root is on (hd0,0) but then remap (hd1) as (hd0). Whereas the root partition for windows boot in my case is the first hard drive listed after 'map', yours is the second I suggest you reverse this. -- [EMAIL PROTECTED] mailing list

As I stated before, I've tried all the possibilities. None of them work. In this case the error is #11: Unrecognized device string. BTW these are IDE drives, not SATA. -mw __ Do You Yahoo!?

I don't mean to discount your reply but I am worried I expressed myself poorly. I think your configuration should look like: rootnoverify (hd1,0) map (hd1)(hd0) Here, I'm telling GRUB that i want it to boot from the first partitionon the second drive, but then act as if it's the first drive for Windows (after grub boots). -- [EMAIL PROTECTED] mailing list

The thing is, tab completion finds only hd0 which grub doesn't seem to realize is the SECOND drive. Using hd1 gives error 21: Selected disk does not exist. Although it appears in device.map, dmesg, fdisk etc. Maybe it's a bug in grub.Gonna send a note to [EMAIL PROTECTED] see what happens. Be a better sports nut!

Now I can't use /dev/hdb but /dev/hdc is OK. So my set up is /dev/hda(WinXP) and /dev/hdc(gentoo), ie, WinXP is on the first IDE as master and gentoo is on the sec IDE also as master. hdd is the CDROM(sec IDE,slave), to complete the setup. So far I've tried every possible permutation of root, rootnoverify and map. I've tried installing the boot loader on /dev/hda and /dev/hdc. On hda nothing works(error 21). On hdc the boot menu appears and I can boot gentoo but not WinXP Error messages: selected disk does not exist, not found or not a block device, could not find device for boot. Sorry, I can't recall the exact context for these messages but this will give a flavor hopefully. I've tried changing the boot order in the BIOS. I can get gentoo to boot if I tell grub it's on (hd0,0)(?!?!) but WinXP won't boot unless I remove the HD w/gentoo on it and bypass grub altogether. fdisk can see both drives OK. Both drives appear in dmesg w/o errors. Both drives appear in the POST screen -- first drive as '0', second drive as '1' I've scoured the web for an answer and now must turn to the authorities on this list as a last resort.
