    Dual booting


    O.K I need some one to break this down for me see I'm going for a dual boot on Windows XP and Ubuntu. Now I did research but there are somethings I don't totally understend.

    My first question is can you dual boot on a RAID 0 with partion?

    My second question in the MBR (master boot record) and GRUB (boot loader) I don't understand how they'll help me choose from Linux to Windows XP?

    Please could you help me.

    This will be possible, but only if the RAID is a hardware RAID. Software RAID will not work -- as I learnt the hard way

    The MBR is the first place the computer looks to find an operating system. In your case, you'll install Grub there, so this is what the computer will find on boot-up. Grub will then present you with a menu listing your operating systems, and asking you which one you want to boot. After you make your choice, Grub tells the computer where the operating system you want to use is located, and the computer will start booting that.

    Understand?

    Ubuntu should take care of all this during installation. Just make sure not to overwrite XP during the linux install, and make sure you choose to install grub on the MBR.

    Good luck!

    Master Boot Record is first sector of Harddisk and it stores Boot Loader, Partition Table and Harddisk Signature. Ubuntu Desktop CD wont ask you for the Location of GRUB. it will install GRUB ( boot loader ) in MBR only.

    i am not sure that Dual Boot will work with RAID or not.

    I installed ubuntu for the first time yesterday, and it is the most painless linux install I have ever experienced. It is smart enough to do everything for you, so I don't think you have anything to worry about. It will detect windows, configure Grub, and install it in the right place.

    The only negative is that you must be sure that you have a hardware RAID. In other words, you didn't have to install any drivers to make it work on windows. If you did, then you have software RAID, which won't work on linux.

    For RAID to work on linux, it must be completely transparent to the OS. That is, the OS must think it is looking at a regular hard disk, instead of an array.

    OK then I have a hardware RAID because I have to set it up before installing the operating system. Now for my second question how do I install GRUB and how do I know when I reformat all drives that it will still be there so I can configure Ubuntu and Windows XP?

    as i mentioned earlier, if your installing through Ubuntu Desktop CD, installer *wont* give any option for GRUB location and it will install it in MBR of Primary Master Harddisk.

    So do you install GRUB after the installation of both operating systems or before the I reformat the drives and redo everything?

    first of all, Install Windows. create Free Space for Linux and install Ubuntu in Free Space. installer will recognize WIndows, install GRUB and set up dual boot for you.

    Okay then so you mean that Ubuntu already has GRUB in its installation or when I install XP install GRUB and then install Ubuntu.

    (sorry if I'm a little slow it can take me some time to learn things).
