 |
|
i tried to install grub on the mbr and not but both i get
GRUB Loading stage1.5.
GRUB loading, please wait...
Error 21
i goog0led some time and i found something that i could try
| Code: | | /sbin/grub-install /dev/hda |
but it didnt work because it says;
| Code: | | /dev/hde does not have any corresponding BIOS drive |
im using a hpt 37x raid controller with just one harddisk |

Can it boot to anything else (on the hard drive)?
Also, you should do a install grub /dev/hd, NOT /dev/hda.
I think.
To do this: boot into a livecd/whatever.
Do the following, substituting in the corrct values for hard drives: | Code: | #grub
grub> root (hd0,0)
grub> setup (hd0)
grub> quit |
Then edit the GRUB conf file: | Code: | #mount /boot
#nano -w /boot/grub/grub.conf |
Customize the grub.conf file, for example: | Code: | # Which listing to boot as default. 0 is the first, 1 the second etc.
default 0
# How many seconds to wait before the default listing is booted.
timeout 30
# Nice, fat splash-image to spice things up :)
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux
# Partition where the kernel image (or operating system) is located
root (hd0,0)
kernel (hd0,0)/kernel-2.4.22 root=/dev/hda3
# Only if you use genkernel. Otherwise remove the following line:
initrd (hd0,0)/initrd-2.4.22-gentoo-r2
# The next three lines are only if you dualboot with a Windows system.
# In this case, Windows is hosted on /dev/hda6.
title=Windows XP
root (hd0,5)
chainloader +1 |
Unmount /boot (using theumount command, it isn't unmount.

You want to delete GRUB's stage 1.5 files before installing GRUB on a harddrive attached to a Highpoint controller.
See this thread for more details :

This is normal.
GRUB counts harddrives the same way the BIOS does.
(hd0) is the drive you are booting from
(hd1) is your second harddrive
(hd2) is your third harddrive
etc.
So, if you only have 1 harddrive, it will be (hd0), and it doesn't matter which controller you have it plugged into.

It should have helped.
The reason this hack is needed is because each time you boot, the Highpoint BIOS overwrites sector 9 on the harddrive with its own information about the drive. This location is right in the middle of GRUB's stage 1.5, so GRUB gets corrupted and won't boot.
Normally when you run GRUB's setup (hd0), it links stage 1 -> stage 1.5 -> stage 2. By deleting GRUB's stage 1.5 files, it will link directly stage1 -> stage 2. Stage 1.5 is optional, so everything should work correctly at this point. |

What does your device map look like ?
You can have GRUB generate one like this.
| Code: | # cd /boot/grub
# rm device.map (if it exists)
# grub --device-map=device.map
Probing devices to guess BIOS drives. This may take a long time.
grub> quit
# cat device.map |

Hmmm, everything looks good. I don't understand why it isn't working properly.
At this point, you should be able to.
| Code: | # cd /boot/grub
# rm *stage1_5 (Highpoint BIOS workaround)
# grub --device-map=device.map (this will use your existing map)
grub> root (hd0,0)
grub> setup (hd0)
grub> quit |
If it still won't boot after this, then I am stumped.  |

So GRUB works at last.

It is possible.
It could also be an IDE chipset driver problem (make sure the correct ones are compiled in the kernel).
It could also be an IRQ routing problem (try passing "acpi=off" to the kernel in your grub.conf). |
