Dual Boot Problem

[darkrain]

I am trying to find away to dual boot Fedora and win Xp. Before people start flaming heres the set up.

Linux is installed as the primary master on ide 0
WinXP is installed on Sata 0.

If I add the WinXP onto the grub boot loader it goes to a black screen with a flashing cursor and thats as far as we go.r

Anybody got any ideas or pointers?

Thanks

It could be that GRUB does not support SATA yet. I have not had a chance to play with any SATA hardware, so I'm not sure.

No flames here, I dual boot XP and Fedora too. Although I haven't booted XP in quite a while.

Are you sure the grub setup points to the correct partition? The windows part of my /boot/grub/grub.conf looks like this:

title Windows
        rootnoverify (hd0,1)
        chainloader +1

This loads the second partition of hd0 (first is 0), aka hda, the primary IDE drive. This isn't SATA hardware, but it might help. I had to manually change the hd0,1 part from hd0,0 because I had a recovery partition on the XP drive. Hope this helps a little.

i believe fedora supports sata
but if u have a sata drive fitted that will default to being the master drive the ide drive will always be read by the system as the slave

i believe that u will have to put grub on the mbr of the sata drive so u can duel boot

sorry dont have a sata drive but got this answer from the pcpro forum

In my case this part :

title Windows
        rootnoverify (hd0,1)
        chainloader +1

is the same as Yours, but when i press enter on Windows, i just got this text on screen :
rootnoverify (hd0,1)
chainloader +1
and nothing happens then

[Bana]

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

Try adding these two ^^ lines above the rootnoverify line.
Also check your /boot/grub/devices.map file and make sure that you have your SATA device in there (i just added mine in as:

(hd1)   /dev/sdb

so my /etc/grub.conf look like this:

title Win2K MainDrive
        root (hd1,0)
        map (hd0) (hd1)
        map (hd1) (hd0)
        chainloader +1

and it works like a charm!

Good luck!

i did as You suggest, but it is does not help me

I forgot to say that I am using Fedora Core2

Lots of people are having this problem - please take a look at my fedora forum posts at http://www.fedoraforum.org/forum/sho...=&postid=14703

I've noted a couple of solutions which have been discussed on various mailing lists.

I was having a dual boot problem but have finally solved it. My set up is as follows: WindowsXP64 on Sata Master using NV SATA on Asus A8N-Sli-D. I have Fedora Core3 64 bit on ide slave (jumper set to slave). I did create a boot partition for Fedora on the ide master.

1. First I set my system to boot off the Fedora ide drive in my bios. I set the Windows sata drive as the second device it shows as sata master in the bios.

2. My drive.map in grub looks like this:

# this device map was generated by anaconda
(fd0) /dev/fd0
(hd0) /dev/hda
(hd1) /dev/hdb
(hd2) /dev/sda

I tied a number of iteration on mapping the drive, but my mistake was mapping the SATA Mater (hd2) to my Fedora root drive (hd1). Once I mapped hd2 to hd0 it dual booted. I think Windows just wants to be hd0 no matter what. Here is my grub.conf

rootnoverify (hd2,0)
makeactive
map (hd2) (hd0)
map (hd0) (hd2)
chainloader +1

I was getting discouraged but now I know it can be done. I am sure I will have to switch the drive order back in bios if for some reason I need to use the Windows install CD. However it is nice not to have to switch booting to either OS using the bios.

I have clso just experimented with changing the Fedora to hda (master ide) and redited the grub.conf -everything works great. the key is mapping Windows correcty

This worked for me. Thanks. Windows can only start from first had drive. I had to map this before using the chainloader.

I had to do another thing as my windows had a recovery partition on sdb1. So had to manually change rootnoverify (hd1,0) to rootnoverify (hd1,1) also.

My grub.conf for Windows

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

Great, what fedora are you using and do you like it?
