Hi

I have to install the Grub Loader to the MBR of my Windows Partition
(4th Partition) and the grub itself (/grub folder) is in my linux /
boot
partition located on the 5th partition. .. how do i do that, i looked
into the manual but i'm not entirely sure about all that.
Is this line correct or am i screwing my system with that ?

grub-install --root-directory=/boot /dev/sda3

thx in advance !!!

First of all, let me say that changing the bootloader without knowing
exactly what you are doing can lead to an unbootable system or otherwise
do great damage to your system.

The problem is, currently i dont have a working (grub/lilo)
bootloader, currently its working with the EFI system of the Mac,
thats how i start MAC Os and Windows
My advice is for you to brush up on the proper nomenclature, for both
disks in the PC world and for grub. This post includes the rules for disk
partitioning in the PC world:http://groups.google.com/group/comp.os.linux.misc/msg/d3544c061662cacf

thx for the hint, but since i have a Mac and this system is a little
bit different to the mac it seems not applicable for this case. since
a mac normaly uses the EFI system and not the MBR system anymore.

Grub works within the same context, but counts beginning at 0. It counts
the first drive it "sees" as drive 0, and partitions on the
drive will also be referenced from 0.

Here are some examples. The first partition on the first disk is
named (hd0,0) by grub. The primary partitions are named as follows:
(hd0,0)
(hd0,1)
(hd0,2)
(hd0,3)

Similarly, the logical partitions within an extended partition are named
(hd0,4)
(hd0,5)

etc

I have to work with the sdb etc stuff because at first i want grub to
start not modify its entries using a Live CD. and thats how i
understand it will be done using /dev/sdb... ?
It is important to note that grub includes an interactive shell mode.
I have found it easiest to use this shell to make sure everything is
working as assumed. One useful grub command is "geometry." That command
is useful in eliminating confusion between hard drives, especially when it
is not clear how grub has "counted" your drives. This comes up most
often with systems which have both scsi (or sata) and ide drives.

Once you have reviewed the documents, then you can layout your plan on
paper. The solution will probably be readily apparent at that point and
you can proceed to reconfigure the bootloader according to your needs.

As i said, at first i need it runing.

By the way it should work somehow because i got this configuration (/
boot partition on internal, /, /swap etc on external) running with
ubuntu, which unfortunately dont work with the programs i need :(

thx anyway Sebastian
