 Posted: Thu May 08, 2003 5:38 am Post subject: Grub Booting Issues... |
 |
|
I know I've seen this before, but I cannot seem to find the solution this time 'round.
I've just setup a new install of Gentoo on a VA Linux Fullon 2240. It's a two hard drives installed using a built in Adaptec 7896.
/boot = /dev/sda1
/ = /dev/sda2
(other partitions not important)
Installed grub, ran grub, and created grub.conf w/o issue (no errors). Upon rebooting, I get to a nice blue screen provied by splash.xpm.gz.
Only instead of offering me my boot choice, I end up with "grub>" prompt.
Manually typing | Code: | root (hd0,0)
kernel (hd0,0)/boot/linux-2.4.20-r2 root=/dev/sda2
boot |
...boots the system just fine.
I have checked my grub.conf several times over, tried re-running the install steps for grub, tried changing to/from MBA, and even tried upgrading to version 0.93.20030118. No good.
Recap...it seems to be seeing the boot sector and grub.conf (or I wouldn't be getting the grub splash prompt). My grub.conf syntax seems ok, I've manually entered both boot lines exactly and the grub prompt and it boots fine. Not sure what else to try...though I know I've done it before.

Can you copy your grub.conf file below? Obviously Grub can access your HDD since it displays your splash image.
Did you try :
| Code: | | kernel (hd0,0)/linux-2.4.20-r3 root=/dev/sda2 |
The command line you wrote will look for your kernel in /boot/boot if i'm not mistaken |

Actually either method will work and I tried both ways.
Here is my grub.conf...
| Code: | # cat /boot/grub/grub.conf
default 0
timeout 30
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
tile=Linux Kernel Version 2.4.20-r2
root (hd0,0)
kernel /boot/linux-2.4.20-r2 root=/dev/sda2 |
...originally... | Code: | | kernel (hd0,0)/boot/linux-2.4.20-r2 root=/dev/sda2 |

Is there any chance that when you were installing grub, you typed this?
I made this mistake. This will install grub onto the boot sector of the boot partition, where what I think you want is to install grub onto the MBR of your hard drive.
Try this from within grub: | Code: | root (hd0,0)
setup (hd0) |
This will put grub onto the MBR, so that it will get loaded at boot. |

Perhaps, but I went back and tried it both ways in case. Besides, it should work from either the boot sector or the MBR and if it was a MBR error it shouldn't have got to Grub stage1.5.
After glancing at the texinfo for grub, I may have found something. I think I might have had to manually set the stage2 boot drive. It seems to sound familar...
Anyone know what switches/syntax "install" needs in the grub shell?
(either way I'll play with it this afternoon and report back) |

Is this what you want?
install [--force-lba] [--stage2=os_stage2_file] stage1_file [d] dest_dev stage2_file [addr] [p] [config_file] [real_config_file]
Details are here. |

Sorta...except that's a direct copy from the man page.
What I was asking is if anyone (who's preferably used it before) knows the exact switches/syntax would best be used by "install"? Trying to cut out a lot of rebooting cause I missed something, espically when I'm not 100 % sure this is the fix/best fix. |
