We begin with the title. This means that the next command, chainloader , is executed without the target partition specified as the target partition is the same, now. The second entry is even simpler. We name a Linux, we call its partition and we boot the kernel. This would be a very likely case for older computers - or ones with a specific boot partition.

You see, it's very simple! Once you get the hang of it, it actually becomes fun. In particular, you need to familiar with The list of command line and menu entry commands. Most of the time, you will not want or need to touch GRUB. When you install operating systems, especially in the right sequence inconsiderate OS first - like Windows, flexible OS later - Linux and family , the GRUB will be installed automatically and relevant entries appended.

We'll use the dd command, which copies information sector by sector. Here's the set of commands that you need to execute taken from the Manual :. Not surprisingly, since we need to write the files to the first two sectors of the floppy disk, we write stage1 to the first sector, and copy stage2 to the second skip first, then write.

Now that we have taken this deep fancy for the command line, I'll leave you with the nuances of different commands for homework. More on dd on Wikipedia. Regarding the GRUB on floppy, that's it.

Since we have copies the stages from OS image, all of the required information is there. Of course, you can always make manual adjustments. But that's the next chapter.

Furthermore, this command can be written in several ways, all equivalent:. After you have installed the GRUB, your operating systems should boot. Once booted, you can once again start playing with GRUB, manually changing settings - adding and removing entries, chainloading other bootloaders, or even hiding and unhiding partitions.

First, before you make any changes to the GRUB configuration file, it is most warmly recommended that you backup the existing menu. You might even consider copying to another machine or printing the menu, in case things go bunkerous. After a few moments, the GRUB command line should show up. Alternatively, you can reach the GRUB command line during bootup.

Let's say you have installed yet another operating system on your machine, Sabayon. During the installation, you skip the GRUB setup. This means that the original GRUB remains untouched - and it does not contain an entry about Sabayon. For all practical purposes, Sabayon is not bootable. Note: GRUB menu entries are called stanzas probably a twist of instance? So, we need to add Sabayon to the list.
