 Posted: Sun Jun 24, 2007 7:32 pm Post subject: SOLVED -- Problems with dual boot on an HP Pavilion Laptop |
 |
|
The particular model number is well disguised, but it is an Intel Centrino duo. This is a used system which had windows working at one time  I've tried to follow instructions for resizing the windows partition, but after doing this windows would not boot. Moving on, I'm trying to get Linux working before working on the Windows part of the problem. I should mention that the bios on this machine only allows booting from the first hard drive!
At the moment I'm suspecting that I may be missing a SATA driver in the kernel configuration, but if so I have no idea what to choose.
When booting: | Quote: | root((hd0,3)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/kernel-2.6-20-r8 root=/dev/sdb2
Error 15: File not found |
fdisk has this to say about my partitions | Quote: | Disk /dev/sda: 80.0 GB, 80026361856 bytes

Many thanks to any who would care to offer suggestions as to what might be done. More outputs from whatever, I'd be happy to supply.

Hi Fred,
From what I can see you are trying to boot linux on the wrong disk
In grub hd0 is sda and hd1 is sdb so you should have
| Code: |
# For booting GNU/Linux
title=Gentoo-Linux-2.6.20-r8
root (hd1,1)
kernel /boot/kernel-2.6-20-r8 root=/dev/sdb2
|
If you ran grub on hd0 you probably overwrote the windows MBR which would explain why you can't boot into it anymore.
I hope this helps.
-Ed

It wasn't booting windows prior to running grub. But at the moment I'm more concerned about getting Linux working. Thanks,

Sorry I missed the first part of your post. I thought root was supposed to point where /boot/kernel was to be found and that would be (hd0,3) I believe.
I'll go have another look at the grub documentation. Thanks,
Fred |

I don't find the documentation all that clear. But since /boot/kernel... is on /dev/sda4, I don't see how it has a chance of booting it I don't tell it where that is, and it seems to me that would be (hd0,3). Am I really that confused?? Thanks,
Fred |

| You grub.conf looks okay. Between do you have the right filename for the kernel in grub.conf |

A reasonable guess. I had been careful about this, but checked this again. Names do match. Thanks,

what about the directory?
could you post the directory listing for /dev/sda4
or you could try
manually booting grub
hit e, when you see the grub
type
root(hd0,3)
kernel /boot/kernel-2.6-20-r8 root=/dev/sdb2
boot
all these 3 command in different lines
you should be able to boot |

GRUB's tab-completion is very handy when you are booting manually.
You can get a list of what files are available in your /boot partition like this.
| Code: | root (hd0,3)
kernel /<press tab> |

I didn't bother posting my /boot directory as I think what you (bjacobt) suggested enabled me to get unstuck. Doing what you suggested I tried various combinations and found that what I needed was | Quote: | | kernel /kernel-2.6-20-r8 root=/dev/sdb2 |
This got the system to boot and I think it is safe to assume that changing grub.conf will have me back in business. I'll probably be asking questions about getting windows working again as some (quite a bit later) point. Many thanks,
Fred |
