Hello,
Installed XP on it's own partition then installed kanotix. Now only Kanootix loads. It loads so quickly, even if there was an option to select XP, I can not see it.
I heard mention of 'chainloader' and looked in the grub folder and found this at the bottom of 'menu.1st.'
title Windows 2K/XP/2003 (hda1)
chainloader (hd0,0)+1
title Windows 95/98/ME (hda3)
root (hd0,2)
makeactive
chainloader +1
Can this be edited to allow a selection at boot?
Thanks,

Now I'm no expert but I think the file you need to be looking at is in /boot/grub/ and is called menu.lst
at the bottom of the file I have an entry like
### END DEBIAN AUTOMAGIC KERNELS LIST
title Windows 2K/XP/2003 (sdb1)
chainloader (hd1,0)+1
You need to edit this with the correct HDD settings.

Sure, just set the timeout in /boot/grub/menu.lst
This section:
Code:
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 5
Of course you must edit that file as root.
If you add a chainloader section for winxp do it either BEFORE or AFTER the automagic kernel list. I usually put a WIndows entry after this line:
Code:
### END DEBIAN AUTOMAGIC KERNELS LIST
This way it will never change when GRUB is updated. |

Part of my grub:
## ## End Default Options ##
timeout 35
title Kanotix
root (hd0,11)
kernel /boot/vmlinuz root=/dev/hda12 ro ramdisk_size=100000 lang=us apm=power-off nomce vga=791
initrd /boot/initrd.img
boot
title Utopian
root (hd0,12)
kernel /boot/vmlinuz root=/dev/hda13 ro ramdisk_size=100000 lang=us apm=power-off nomce vga=0x31A
initrd /boot/initrd.img
boot
### END DEBIAN AUTOMAGIC KERNELS LIST
title Windows XP
chainloader (hd0,0)+1
Adding "timeout 35" can slow it down so you can read it  adjust it if you want |

Hi piper,
Increasing the 'timeout' was all it took. I may to the 'chainload' but at this point it is no longer necessary. Actually, I really don''t know what to expect if I should use it?
I am loving this OS more every time I boot into it.
To all of you who replied, thanks for the help!
Cheers,

Fedora uses
Code:
title Microsoft Windows 2000
rootnoverify (hd0,0)
chainloader +1
and Kanotix/Debian uses the GRUB commands others have posted above.
"rootnoverify" tells GRUB, "Don't mount this partition." (With Linux, GRUB evidently mounts boot partitions before passing boot parameters to the OS.) "chainloader" means, "Hand off control to Microsoft's boot loader.". And "+1" means that GRUB looks for Windows' boot loader on the first sector of the Windows partition.
All this assumes that Windows is on the first partition of the first hard drive, hd(0,0) in GRUB-speak. If it's not, things are a bit more complicated. |

Hello eco2geek,
Thanks for a further explanation. It is just a bit above my understanding, at the moment, but as I keep reading and doing I am sure things will fall into place.
I don't know if this is harder or easier than when I first got into computing (Win 3.1). Guess it is easier since I have the experience I do have. I really need to get all the new commands and file names straight in my head. That, plus, all the new program names has this old gal very busy learning. I haven't had as much fun since I started learning to write HTML.
regards,

Thank you for a simple and clear explanation. I don't dual boot but I have wondered what "rootnoverify" and "chainloader" and "+1" meant. |

Hi
I have a triple-OS-System (XP(hda1),Kanotix(hda6),Knoppmyth(hda10)). I have Grub in my MBR and want to chainload to LiLo on hda10
In my menu.lst
Zitat:
title KnoppMyth
chainloader (hd0,9)+1
this gives me an Error 13 on choosing this Entry on boot
Zitat:
Error 13: Invalid or unsupported executable format
is it the +1 that's wrong or should i check if lilo really was installed in / of hda10? |

gives
Zitat:
Error 22: No such partition
which makes sense, because there is no hda11 and (hd0,9) should correspond to hda10
more hints? |

here is my menu.lst. with the second "title entry" i start KnoppMyth directly frim GRUB, but i need a chainload ...

Very confusing to me
title KNOPPMYTH, kernel 2.6.17-chw-8
root (hd0,5)
What is that ?????
-----------------------
title KnoppMyth
chainloader (hd0,11)+1
Is this different than above ??????
I am confused with this
If so try putting it above ### END DEBIAN AUTOMAGIC KERNELS LIST
KnoppMyth is what, a Microsoft Media Center clone |

fdisk -l will bring light to the sceene. all aother is guessing.
a Chainloder for hda10 kann only used with an other grub in msr of had10
I think this grub is missing. so no need for an extra chainloader.
Here his problem:
title KNOPPMYTH, kernel 2.6.17-chw-8
root (hd0,5)
kernel /vmlinuz-2.6.17-chw-8 root=/dev/hda10 ro ramdisk_size=100000 lang=de apm=power-off nomce vga=0x317 splash=silent
initrd /initrd.splash
boot
### END DEBIAN AUTOMAGIC KERNELS LIST
title Windows XP Professional
chainloader (hd0,0)+1
title KnoppMyth
chainloader (hd0,11)+1
####### end of faullty grub.menu
here his soluttion:
title KNOPPMYTH, kernel 2.6.17-chw-8
root (hd0,5)
kernel /vmlinuz-2.6.17-chw-8 root=/dev/hda10 ro ramdisk_size=100000 lang=de apm=power-off nomce vga=0x317 splash=silent
initrd /initrd.splash
boot
### END DEBIAN AUTOMAGIC KERNELS LIST
title Windows XP Professional
chainloader (hd0,0)+1
######## end of grub.menu
Since his KnoppMyhth is a Found @ KNOPPMYTH. This is a korrekt booting entry. |

Pretty much what I said in english, except the fdisk -l part, solution, and why I said confused. (asking about both KNOPPMYTH)

KnoppMyth is a MythTV-System (i think it existed before MCE was invented) based on Knoppix. It features a Live-CD with usable Frontend (Clients) and an Install-Script for Backends and Frontends.
Zitat:
title KNOPPMYTH, kernel 2.6.17-chw-8
root (hd0,5)
What is that ?????
ahh, you're right, it is confusing. i have got a seperate /boot partition hda6. to get GRUB in MBR to boot KnoppMyth i have copied the kernel and initrd from Knoppmyth's /boot on hda10 to hda6.
@schnorrer
Zitat:
so no need for an extra chainloader.
trying fdisk -l later ...
do you mean that i can only chainload to GRUB if the system is on hda10 and not to LiLo?
I want to chainload to LiLo which was installed in MSR of hda10. Why? Because LiLo is already configured for suspend2, bootsplash etc. and it would make updates of Knoppmyth much more easier, because i could leave my Grub config in MBR as it is and a Kanotix Automatic-Kernel-Update (Update-Gui) would not mess it all up again.
thanks
