| Duel Boot
I am wanting to duel boot a machine with Win XP. I have one hdd with Win XP already installed and running on it, I have a seperate hdd with Freespire 1.0.13 on it up and running. Question is, can I just plug both hdd's in and the grub menu will detect it, or do I need to change something inside Freespire first to detect a duel boot hdd? My Linux skills are minimal, please keep that in mind. |

| you have to edit menu.lst and device.map files.
plug-in FreeSpire disk as Primary and Windows Disk as Secondary ( slave ).
FreeSpire will boot up on switching on the machine.
open /boot/grub/menu.lst file and add this code at the end of file: Code: title Windows XP
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1
save file and open /boot/grub/device.map file.
add this line if your harddisks are SATA, replace hdb with sdb.
reboot machine.
*you must have root privileges to edit those files.
in case, it doesn't work, plug-in both disks, execute 'fdisk -l' command and post output here.

| I added the code from DC to my menu.lst and also to device.map. I saved both files and rebooted. The grub menu does not show my Win XP disk as bootable (i.e. no selection to boot to). I re-opened device.map and the added code is no longer there. Do I need to sudo mount before rebooting? If so, how? I forgot the command  .
Here is the menu.lst: Quote:
# Generated by jiffyboot version 9.1. If this file is edited, the
# system will stop modifying it. To allow the system to resume
# management of this file, remove it and run /sbin/jiffyboot
default=0
timeout=0
fallback
title hidden
configfile (hd0,0)/boot/grub/menu-normal.lst
title Windows XP
rootnoverify (hd1,0)
map (hd0) (hd1)

| FreeSpire is using jiffyboot utility to auto-generate menu.lst file. we have to replace menu-normal.lst file with menu.lst.
post the contents of /boot/grub/menu-normal.lst file.

| Windows Boot Loader must be installed in the MBR of Primary Harddisk OR Boot Sector of Primary Partition of Primary Harddisk. we are plugging Windows OS' Harddisk as Secondary. Windows OS will complain coz of that and wont boot. mapping code is cheat code. with mapping, Windows Boot Loader assume that its in Primary Harddisk.

| Ok...I replaced the menu.lst with the code that DC suggested. The grub boot loader recognizes the Win XP hdd. But when I select the Windows disk I get this error: Code: Error 21: Selected disk does not exist
When I select Freespire hdd I get this error: Code: Kernal panic - not syncing: VFS: Unable to mount root fs on unkown - block (3,1)
Now I can't boot into the freespire disk. Even If I unplug the windows disk and run freespire alone. I am typing this message on the windows disk running as master and freespire disk unplugged. I know something went wrong...wish I knew what it was. Thanks for the help in advance. | |
