[gentoo-user] Grub won't boot SATA WinXP disk

[gentoo-user] Grub won't boot SATA WinXP disk

[mattr]

I just put in a SATA drive into an otherwise PATA machine.  I put Windows XP 
on the new drive.  I added the following to my grub.conf:

title=Windows XP
rootnoverify (hd2,0)
makeactive
chainloader +1

but when I tell grub to boot this item, I get an otherwise blank screen with 
the text:

rootnoverify (hd2,0)
makeactive
chainloader +1

and nothing else happens.

I have never had difficulty getting grub to play with Windows in the past, but 
that was always with PATA hardware.

I have tried editing the grub configuration at boot time to see if grub 
doesn't like my drive number or something.  I used the TAB autocompletion 
feature which lists three disks (hd0, hd1, and hd2).  The former two are 
definitely my raid array based on the number of partitions they contain.  The 
latter has only one partition (according to grub's TAB autocompletion) which 
is as it should be given that it is obviously the Windows disk.

I'm at a loss here.  Any help would be greatly appreciated.  I'm afraid I have 
to use my BIOS to switch boot disks until I resolve this.

Hi, I have had a similar problem, and it was about the disk and
partition numering. When I configured grub, it seems to me that SATA
disk was disk 0, but when botting it was disk 1, I saw you try some
combination of numbers, but, you are sure about partition number ? it
was in fack at first partition your windows system ? I will try
something that way, I could help more if you print a fdisk -l here.

holpe it helps, Allan

Hello there,

Try adding a map in there like this

map (hd1) (hd0)
map (hd0) (hd1)

now I am assuming that your windows is on /dev/sdb in linux or its it
your first drive if it is /dev/sdb the above code should work, put
this under the windows title :-)

the reason you are puting this twice is to swap both of the dirves

Hope that helps

Sincerely,
Christopher

Problem solved!  My system is arranged thusly:

Grub is installed on hd0 and hd1 (they are a RAID mirror).  These are known as 
hda and hdc in Linux.  Windows is installed on hd2,0.  This is known as sda1 
in Linux.

I had to add:

title=Windows doesn't play nicely with others
map (hd2) (hd0)
map (hd0) (hd1)
map (hd1) (hd2)
rootnoverify (hd2,0)
makeactive
chainloader +1

to my grub.conf.  Actually, I could simply do these maps instead:

map (hd2) (hd0)
map (hd0) (hd2)

since hd0 is identical to hd1.

Thanks for all the help, everyone.

I've done this on SATA and IDE drives and combos of
the same and I never got XP to boot unless I used
rootnoverify (hd0,0). Macro$haft insists on being
first in my experience. FWIW.

Make a grub boot disk(if you haven't already) and
practice until you find the proper sequence of
commands; then you can put them into a conf file and
do a grub-install. I'd do that first. A false move
could wipe out your MBR.

As I recall I completey destroyed the boot partition
on a brand new HD while fumbling with GRUB. But it was
still under warranty "Whew!"

The map command bypasses that little problem, by virtually fooling the
M$Windoze OS to see that it is in the first hard drive.

So would an 'intentional' move to install Grub in the MBR of the first
device.  A boot floppy is handy, but as long as Grub boots normally
you can press 'c' to drop into a command prompt and use find to find
whatever partition you're after, or 'e' to edit individual entries in
the menu, until the particular OS boots.

Using the fixmbr command from a WinXP installation CD would restore
it.  Better though to install Grub's boot code in the MBR.  BTW, the
fixboot command will restore the partition boot sector in a hosed
WinXP partition.  None of this will help with a hardware failure of
course, and I am at a loss as to how any software manipulation that
Grub can perform would damage a hard drive.

In conclusion, I agree with Christopher's suggestion that the only way
to make WinXP boot from any other than the first drive is to use the
map command.  A point to note is that WinXP is installed on the third
device so instead of hd1, hd0 you may want to try hd2, hd0.

Good luck.

Not this time! Even the diagnostic floppy from the
Maxtor site proved the drive was toast. Probably a
coinkydink; it's hard to imagine GRUB physically
damaging a drive. That's why I covered my butt by
saying "while fumbling" instead of "_by_ fumbling" :^D
