 Posted: Tue Mar 23, 2004 3:33 am Post subject: Just double-checking how I'm gonna dual boot this. |
 |
|
So I've got my 40GB drive as one giant partition, with winxp on it. Now I'm going to use Partition Magic to resize it, and create another partition of about 8GB. Then I boot off the LiveCD and set up as normal, then when it gets to the fdisk parts, I delete that second partition (which should be hda2) and create hda2, hda3 etc. Then I install grub on (hd0,0), which overwrites the windows bit, and then I add the necessary lines in grub to boot windows again?
Am I missing anything? |

if your using the same hard drive for both os's what i did was created a 20gb partition for gentoo, set it up logical 32mb (boot) 512mb (swap) and remaining (root). the drives were hda5, 6, 7. setup as normal, installed grub, run grub, then root (hd0,4) setup (hd0)-mbr.
then continue on. |

I don't know much about doing the dual boot, but I have heard a lot of ppl saying that Windows XP likes to handle the boot and you edit the xp boot menu to point to your gentoo installation.
Search the forums, there are a lot of posts on this.

| ya xp does like to handle the boot but if he sets up his grub.conf file right he can get the dual boot menu going just make sure in setup you put setup (hd0) so it goes into the mbr. |

Alright. So I can let grub take over booting for both then without a problem? I've heard some things just like Insanity5902 has, and although I did this once before about 6 months ago, I can't remember what I ended up doing  . Also, why are the drives starting at hda5? hda1 is your winxp right? and the extended would be hda2, so should they be 3-5? not 5-7? |

The "problems" that arise with windows and grub booting is that if you install grub to the mbr then later reinstall windows, windows will reset your mbr making grub unavailable.
And they should be 5-7. primary partitions are located at hda1-4. These partitions are obviously NOT primary, but are logical partitions located in the extended partition. Since they aren't primary, they cannot be given hda1,2,3,or 4. Therefore they are given 5-7. |

| thagame: It's all starting to slowly come back. I think this is what I did last time too. Would you mind tossing up your conf if it's not too much trouble? I'm pretty sure what I need to have, but getting the confirmation would be nice just so I know I'm not missing anything, and I actually am thinking straight. |

ok heres how i did it, change to your drives,
emerge grub
grub
root (hd0,4)
setup (hd0)
quit
nano -w /boot/grub/grub.conf
default 0
timeout 30
splashimage=(hd0,4)/grub/splash.xmp.gz
title=Gentoo Linux
root (hd0,6)
kernel (hd0,4)/bzImage root=/dev/hda7
title=Winblowz XP
root (hd0,0)
chainloader +1 |

Here's part of your problem
| Code: |
title=Gentoo Linux
root (hd0,6)
kernel (hd0,4)/bzImage root=/dev/hda7 |
It should be:
| Code: |
title=Gentoo Linux
root (hd0,4)
kernel (hd0,4)/bzImage root=/dev/hda7 |
The confusion is that "root" is used in 2 completely different contexts.
The "root (harddrive#,partition#)" tells grub that your kernel will be on the that partition.
Then the "root=/dev/hda7" is a kernel option telling the kernel where your root (or your "/") partition is. |

The reason it worked is you'd do something like this:
root (hd0,90000000) **just doing this to exaggerate**
kernel (hd0,4)/bzImage root=/dev/hda7
See, he set the true path to the bzImage so the root line really becomes useless.
The correct way to use the root command would be like this;
root (hd0,4)
kernel /bzImage root=/dev/hda7
Hope that makes sense. |
