Dual Boot (2 different Disks) Fedora C3 and Win2K

zepplin611 · 09-20-2006, 10:59 PM

Greetings all - I hope you can help.

I have installed Fedora Core 3 on /dev/hda and Win2K on /dev/hdb

I have no problem booting into Fedora.

I can not get into windows however.

The error I get is:

"rootnoverify (hd1,0)
chainloader +1"

Here is the output from fdisk -l

[root@localhost grub]# fdisk -l

Disk /dev/hda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders

Here is the output of /boot/grub/grub.conf:

#boot=/dev/hda

splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu

initrd /initrd-2.6.9-1.667.img
title Other
rootnoverify (hd1,0)
chainloader +1

I believe I need to add some commands to the grub.conf file to make windows think that it is on the primary drive...can anyone help?!?!?!

thanks,

zep

Have a look at this.

You are missing the section to boot Windows in /boot/grub/menu.lst

The map command is used to remap Windows as the 1st boot drive, since that's what Windows requires to load.

Add this and you should be in business:

title Windows
map (hd0) (hd1)
map (hd1) (hd0)
chainloader (hd1)+1

Here's my complete menu.lst for you to see how it's all laid out. This is for SUSE, but GRUB is GRUB, so something very similar should work for you.

Here's your menu.lst "Winders" stanza:

Code:

title Other
rootnoverify (hd1,0)
chainloader +1

There are 2 things that stand out as possible problems:

"Winders" sometimes needs a makeactive directive, if so, put it before chainloader +1.

The 2 map directives are also probably needed.

While it is good practice to have the title line name the OS, it's not necessary for GRUB to work.

Finally, if your hdb contains an unaltered M$ install, i.e. w/ an intact MBR, then either rootnoverify (hd1,0) or rootnoverify (hd1) should work.

Here's what the final stanza might look like:

Code:

title ... XP ...
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
makeactive
chainloader +1
