Question #78237 on Ubuntu changed: https://answers.launchpad.net/ubuntu/+question/78237
Tom proposed the following answer: The grub boot-loader stands for "GRand Unified Boot-loader". It's not really linux as it is designed to be better at talking more directly with the machine. That's why it starts counting at 0. When it says (hd0) it means sda. (hd1) would be sdb but it's only talking about which Master Boot Record to make point to the main part of grub. During bootup it starts with a splash-screen about the mbord and then looks quickly at drives plugged in and then boots into the bios stage which does it's own much more advanced hardware detections. The bios then looks up the MBR of the first hard-drive which tells it where to find the boot-loader (Lilo & Grub are the 2 boot-loaders most often used by linux). Then control is passed on to the boot-loader which loads in the kernel of the OS and then passes control of the machine to the OS. Then the OS does it's own hardware detection but tends to cheat a bit by looking up what the bios found ;) -- You received this question notification because you are a member of UF Unanswered Posts Team, which is an answer contact for Ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntuforums-unanswered Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntuforums-unanswered More help : https://help.launchpad.net/ListHelp
