Dualbooting F12 + Windows 7 problems.

[Springs]

Hi all,

I've had F12 since the release and one thing i haven't been able to do is get F12 and Windows 7 to dual boot with each other. At the moment I'm having to remove the Fedora sata cable so i can boot to windows.

I'm hoping someone will be able to help me solve this problem once and for all.

I've included the outputs from fdisk and my grub conf

Hello,
have you triied

title Windows
        rootnoverify (hd1,0)
        chainloader +1

?

I've tried pretty much all the variations.

hd0,
hd1,
hd2,

and all 3 with either 0,1,2,3 at the end.

Results vary. I either get error messages saying there is no partition etc or reboots the machine

Hummm....
I have heard that windows 'wants' to be started from the first disc.
You can try this trick :

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

[Springs]

reboots the machine.

The problem is reported in the grub manual (see http://info2html.sourceforge.net/cgi...9DOS%2FWindows for instance)
Perhaps you could try

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

Could you report the error messages (if there is some) ?

What happens if you reverse the positions of the cables - make the windows disk first, linux second? You would have to change the drive numbers in grub, and change your bios to boot from the 2nd drive.

from your outputs of fdisk and grubconf, it is not clear whether you have three hard disk or two hard disk, there appears some anomaly. In fdisk there is sda & sdb whereas in grub conf there is hd0, hd1 & hd2.

I have two hard disk (one with 250 GB and other 80 GB) and i have installed F13+ winxp on first Hd and Win7+ F12 on second HD and everything works fine (except ATI 3d drivers for my graphic card which i am trying)
