 Posted: Tue Apr 13, 2004 2:44 pm Post subject: problem after reboot...GRR my head hurts!! |
 |
|
I can now get all the way to rebooting the CPU. When GRUB loads...
1. it has lines all through the screen (i think i can fix it by taking out the splash image).
2. it will not start Gentoo or Windows. It says the kernel is not loaded when i try to do Gen and something about the chainloader when i ty to do Win.
my set up is...
/dev/hda1 Win Xp
/dev/hdd1 linux boot
/dev/hdd2 linux swap
/dev/hdd3 linux root
the most frustrating thing is I get no errors when I am going throught the install phase.

Can you post the contents of your grub.conf file? That would help us diagnose your problem...

Ive recieved the same thing with this most recent build of grub.
My fdisk of my linux disk is:
hdb1 /boot
hdb2 linux swap
hdb3 /root
my grub.conf file is:
default 0
timeout 30
splashimage=(hd1,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.3
root(hd1,0)
kernel /kernel-2.6.3 real_root=/dev/hdb3
Same problem, its like the splash.xpm.gz file is corrupt. I have tried to emerge grub several times. all resulting the same way. |

Hmm.. it looks like you said that hdd1 was your linux boot, but your grub looks like it is pointing to hdc...

Shouldn't it be more like this?
| Code: | title=Gentoo Linux
root (hd3,0)
kernel (hd3,0)/boot/bzImage root=/dev/hdd3 vga=795 |
You could give that a try.

solomonHk,
You need to change your (hd1,0) to (hd0,0) instead (in all instances), then it should work.

why would it be hd3 i thought under grub 1st hd was hd0 2nd was hd1 and 3rd was hd2???
so by that hd3 would imply i have 4 hd's

You might have 4. Your cdrom is typically detected as such, since it is IDE. My guess is that it was detected as hdc.
Did you try it? Did it work? In any event, this may be what is causing you grief -- that your cdrom is posing as a hd (which is nomral).

i am at work so i will have to wait till i get home to try it out. thank you though for the insight. i had no idea that the cd could post as a hd i will try it that way then and see.

Yeah,... you should be referencing hd3.
hda = hd0
hdb = hd1
hdc = hd2
hdd = hd3
Even though you do not have 3 HDs, the way you have them set up on the IDE order effects the drive name. In other words, regardless if it is only your second harddrive, it takes its ID from what IDE slot it fills.
In update to my problem:
| Code: | root (hd0,0) //works but I am not sure how as i didnt install grub to my MBR, I installed it to my second disk hdb. and why did this change just with an update to grub???
kernel /kernel-2.6.3 real_root=/dev/hdb3 //had to use real root otherwise I would boot into busybox. |
Anywho, thanks grooveman for the (0,0) suggestion. |

Wrong. grub ignores CDROM's, DVDROM's, etc for numbering. It only counts hard drives.
| acidburn wrote: | | i thought under grub 1st hd was hd0 2nd was hd1 and 3rd was hd2??? |
Absolutely correct. You should referencing hd2 if your linux partitions are on your 3rd hard drive. The problem is that your grub.conf is calling root with the wrong argument. Instead of
it should be
This is because root in this case is not asking you to point to your root partition, but it is asking you which partition contains your kernel. For you, that is hdd1 = hd(2,0).
For your windows boot problem, you should change
| Code: | | rootnoverify=(hd0,0) |
to
| Code: | | rootnoverify (hd0,0) |
If that doesn't work, try to post the exact error message you get.
EDIT: For the windows problem you could also try
between the rootnoverify line and the chainloader line.

no wrong, i can see it as it loads my environment variables that it will address, temporarily, certain hd values to cdroms. MIND YOU, this is not at high runtime envs. so, dont say wrong unless you are absolutely sure, I can print my fstab and my grub.conf and prove you wrong. |

Daveb is correct, in fact GRUB does not know anything about the kernel that has not been loaded yet. GRUB obtains its harddrive information directly from the BIOS, and GRUB's drive numbering is in the same order as the BIOS's boot order.
(hd0) = the harddrive you booted from
(hd1) = the second harddrive in the BIOS's boot order
(hd2) = the third harddrive in the BIOS's boot order
etc. |

this is what i am going to put in the grub.conf
sys =
/dev/hda windows XP pro
/dev/hdb CDRW
/dev/hdc back up hard drive
/dev/hdd gentoo
so....
| Code: | default 0
timeout 30
title=Gentoo Linux 2.4.24
root (hd2,0)
kernel /kernel-2.4.24 root=/dev/hdd3 vga=795
title=Win XP Pro
rootnoverify (hd0,0)
chainloader +1

Just keep in mind, if the BIOS is set to boot from the Windows drive, GRUB will see the drives like this.
| Code: | (hd0) /dev/hda windows XP pro
/dev/hdb CDRW
(hd1) /dev/hdc back up hard drive
(hd2) /dev/hdd gentoo |
But if you set the BIOS to boot from the Gentoo drive, GRUB will see the drives like this.
| Code: | (hd1) /dev/hda windows XP pro
/dev/hdb CDRW
(hd2) /dev/hdc back up hard drive
(hd0) /dev/hdd gentoo |
Make sure grub.conf is setup accordingly. |

Yes. Since GRUB gets its info from the BIOS, any changes there will directly affect GRUB. |
