Grub Guru needed Sata + IDE booting

wavesound · 01-24-2007, 03:59 AM

Hi

Just done a search on this forum and not quite got the answer I need yet.
I'm convinced I have just missed something simple here re the way Grub see's disks.
I have
hda windoxe Xp
hdc debian kubuntu
and
sda ubuntu Edgy

After SMART telling me my 150 gig was about to die (thank you) I upgraded to a SATA disk 250 gig.

I have installed Edgy EFT 6 10 from Linux magazine.

Here is my drive config:

************************************

Disk /dev/hda: 61.4 GB, 61492838400 bytes

************************************************

Here is the drive mapping:

***********************************************

(hd0) /dev/hda
(hd1) /dev/hdc
(hd2) /dev/sda

***********************************************

And here is the menu list I use,
only the top kernel will boot
I can't boot the sda or windows on hd0

********************************************

What am I doing wrong here.
I have spent hours on this.

Is it this drive mapping causing the problem?

I have no primary slave anymore, it's the sata disk.

I note that my kubuntu is now on hd0 same as windows!

Cheers

If that first entry boots, I'd say you installed grub over the top of your XP partition. Have a look at /dev/hda1 when you get a linux system booted.
If so, I'd be betting on an re-install - of both XP and grub.

Yes this start ti filter into my mind.

So it's do this fix mbr thing in XP ( been that long I bet I cant remember the pw!)

Then fix the mbr with linux?

Many thanks

Probably not that easy. If it boots with "root (hd0,0)", that means the stage files were installed there.
fixboot/fixmbr won't resolve that - and if you reinstall XP you'll wipe out grub.

I'd be inclined to reinstall grub (the package) to where you want it, re-write the MBR to point to the new location. Then check things still work (i.e. boots), and then do XP.
Then you'll still need to go back and fix the MBR for grub after XP clobbers it.

Remember that this is all guesswork by me without being able to look at what's actually on each partition.
Lots of luck.

Hi I think I'll run the live CD breezy and back up Home dir of Ubuntu.
Just to add fog to a misty day I installed a thing called GAG and it's boots windows fine but not the Linux's ( wonder if it supports SATA?)

I don't have enough hours to reinstall XP (at least I have a disk!) and SP 2 or whatever it's at now, and as for drivers and stuff, must be here somewhere.
