    Cool 3 OS on 2 drives?

    Hello,

    It is posible to instal 3 os on two drives? I have 2 SATA Drives and one IDE drive... On first SATA i have XP and VISTA on second SATA i have data/programs/music etc... Now i want to install SUSE on third IDE HD and have a 3 os... Should i put IDE HD as a secondary master or leve it as secondary slave? It is harmless to my data and other systems? For now i always install only 2 os (in exemple, XP and linux) on One drive... I'm worry that i will destroy something but in other way its best way for me...

    Best Regards!

    Linux won't bother (in contrast to Windows).

    Yes (if you don't make any serious mistakes. If linux should not touch your "other OS" or their data partitions, then don't tell linux to touch them, it only will if you tell it to do so).

    The only thing will be to setup a correct boot loader configuration and let linux (or "a linux bootloader like GRUB" to be more precise) handle booting all OSes (there are also ways to do this via Windows bootloaders), both will work but both require accuracy.

    Search the Web for tutorials on "Dual Booting" or "Multi Booting" in context with Linux and Windows and study them _carefully_.

    Yes possible. 20 OS's on 10 HDD's as well. Just be very carefull during install and check whether the partitioner is doing what you want.
    AND: BACKUP BACKUP BACKUP.

    I think you can leave it as it is.

    > It is harmless to my data and other systems?


    You never know... I would disconnect the power cable of both sata disks
    before installing to be sure they are not detected by the installer. And
    also, make a backup of the most important files in both disks before
    proceeding.

    The main problem you may face is "how" booting/reaching opensuse.

    Currently, I guess sata hard disks have preference in bios for booting, so
    unless you install grub under sata disk and destroy the windows bootloader
    (something that I would NOT recommend) you will always get windows.

    Another approach is to change the booting preference in BIOS to get IDE
    device first (before sata) so linux boots in first place. This way you can
    either install Grub bootloader into the MBR of the IDE disk or in the first
    sector of a partition. Then, you can configure Grub for booting your
    windows installations.

    It is a delicate task, not for beginners, as some problems may arise. Always
    backup all your data and be prepared for the worst scenario you may
    imagine :-P

    And that is a forum! No comments like use google or go to hell with newbie questions... Pure help :] Maybe there is some true about ppl who using opensource software that they think in diffrent way...

    So, summary...

    The best way is to unplug SATA's drives, install suse and then configure the Grub...

    Can't find right now the option in bios to boot from IDE hymmm... Must check better...

    But if even the bios will be adjusted to boot from ide what about MBR on SATA drive when i will connect them again? It will not crash all the work?

    I will check thath to

    Thx for your patience and help ppl )

    ps. sorry for my english

    Or it can be a "lifesaver" ;-)

    In the event you leave all the hard disks connected, you have to be *very
    careful* with:

    a) Partitioning: manually selecting the openSUSE installation so it goes
    under the desired hard disk (usually represented with some kind
    of /dev/sda1, /dev/sdb1 and /dev/sdc1 scheme.

    Which one is the IDE one?

    It is not so easy to figure what is the right and choosing the wrong one can
    override you windows installation "at all".

    b) Installation of the bootloader: very careful with this one, as if grub
    gets installed into the wrong place, you maybe unable to boot into windows
    again. At least not in an easily manner.

    If you have only one disk connected, you cannot fail as the installer will
    only detect one disk so openSUSE will be installed in the right disk and
    bootloader will go into the right place, no chance for failure. That was my
    point :-)

    openSUSE is by far more configurable in regards hard disk configuration and
    detection and bootloader setup, so I think is better to keep the windows
    installation untouched to prevent any unwanted result.

    Anyway, this can lead to further issues, I know, but at least your current
    data and windows installations are a bit more safe.
