 |
|
Hi,
I have installed fedora on primary hard-disk and and Win on secondary
hard-disk.
Fedora is booting fine, but Win is not booting,
When selected Win for booting from grub GNU. Last prints that i can
see on the monitor is,
rootnoverify (hd1,0)
chainloader +1.
But windows boots when i select hard disk-2 for booting.
Thanks,
-Mushtaq Khan |

I think you need this the other way round - Linux will boot from anywhere,
but Windows will only boot from the primary HD (AFAIK). So when you "select
hard disk-2 for booting", you are essentially telling the BIOS to make HD2
the primary one.
I think.

Take a look at the last 25 lines of this file:
<http://thadlabs.com/FILES/sysconfig.txt>
That's a system triple-booting into either Solaris 10, Fedora 9, or
Vista.
Vista was originally on the one (and only) disk. When I added a second
HD
I used the BIOS to make that second disk (with Solaris and Fedora) the
first to boot. All three OSs are selected from Solaris' grub, and they
boot
and work fine. |

YMMV.

Add two map () () statements to the windows portion of menu.lst.
From GRUB docs:
4.2.6 DOS/Windows
-----------------
GRUB cannot boot DOS or Windows directly, so you must chain-load them
(*note Chain-loading: . However, their boot loaders have some critical
deficiencies, so it may not work to just chain-load them. To overcome
the problems, GRUB provides you with two helper functions.
If you have installed DOS (or Windows) on a non-first hard disk, you
have to use the disk swapping technique, because that OS cannot boot
from any disks but the first one. The workaround used in GRUB is the
command `map' (*note map:, like this:
grub> map (hd0) (hd1)
grub> map (hd1) (hd0)
This performs a "virtual" swap between your first and second hard
drive.
*Caution:* This is effective only if DOS (or Windows) uses BIOS to
access the swapped disks. If that OS uses a special driver for the
disks, this probably won't work. |

Windows does boot from the second from the secondary HD but it has to
put its boot loader on HD1.
