Change Manualy Grub2 menu.lst By Force On Karmic
Grub2 is derived from PUPA which was a research project to investigate the next generation of Grub.
Grub is dinamically configurable, it loads its configuration at startup, allowing boot-time changes such as selecting different kernels or initial RAM disks, so Grub provides a simple, bash-like, CLI which lets user write new boot sequences.Targets of Grub2 are :- Scripting support (conditional,loops, variable and functions)
- Graphical interface
- Portability for various architectures
- Dynamic loading
- Real memory management
- Internationalization
- Rescue mode saves unbootable cases
- Cross-platform installation
- Modular, hierarchical, object-oriented framework for all systems
- Fix design mistakes in Grub legacy
Grub2 will be the default in ubuntu 9.10 Karmic Koala, so to they who already familiar with the original Grub (Grub Legacy) its must be hard to find where the hell is menu.lst. Darn right you will not find it, coz' they change it as grub.cfg.Learn more about GRUB2 in ubuntu forum here, definately you will get some headache... (kidding).There is a simple way to change your Grub menu.lst (grub.cfg), they said they not encouraged this action...."Manual editing of /boot/grub/grub.cfg is not encouraged. Think of Grub.cfg as a result, not as an initiator. The files that should be edited are contain in the /etc/grub.d folders and the /etc/default/grub file."
but who care? right? as long as you can take control of your Grub. ^_^ you see that... just to change menu.lst grub you should change it on two different places, and you should also update your grub too.Basically grub.cfg is read-only file, even attempting to open, edit and save this file using root privileges cannot be done until the 'read-only' status is changed.If you want to take control of your Grub easily just type this commands on your terminal, this will give you right to make any change on read-only grub.cfg file :sudo chmod +w /boot/grub/grub.cfg
followed this command to change it necessery things you want to change :gksudo gedit /boot/grub/grub.cfg
Now you can edit that menu.lst as you like, but note this.... don't ever run update-grub command, if you do, it will returned to 'read-only' status.
