    Default Using two operating systems on one computer

    Im currently using Windows, but heard Linux is pretty good. My brother is adament that he wants to install Linux, but Im not sure I would want that on the computer. I was wondering is it actually possiable to have two operating systems on one computer?

    Yes it is possible to install 2 OS , the same way we install Xp and 7 , but the only difference is the linux has different file format than Windows and it will over ride the MBR of windows.

    So let me get this straight, you can install two different Windows but cant install Linux and Windows.

    You can install Linux on windows but cant uninstall it because sometimes it can corrupt the MBR which is stored in C:drive Primary drive. even though you install linux on other partition for e.g D:drive and later if you format D drive to use only windows but since the MBR file is in C: (default). There are changes of it getting corrupt and you end up loosing both. So best option is to use live Linux OS that is from DVD Drive instead on installation on hard drive.

    Don't get confused with terminology. OS's file system are different. Therefore to have different OS in a single PC you need to make space in the harddisk with non formatted space initially. All windows systems can be made bootable with different OS's. If you have noticed the file system for windows are FAT or NTFS. Even portable HDD's are formatted in NTFS/FAT, similarly each OS has its own file sytem which is unreadable to the other OS, although linux reads NTFS!

    First and foremost thing which you need to do is allocate space on the HDD, or purchase aditional HDD.
    Second comes the boot loader. Linux comes with the GRUB Boot loader which works pretty fine with all the OS's. I use both ubuntu and Win 7. This boor loader helps us to choose the OS when the computer starts up. Edit the bootloader for a 3rd harddisk and install the 3rd OS there...

    RAM has nothing to do with different OS's. Each OS requirement is different, and so you need to have a the min of each. that doesnt means if Linux needs 2GB and Fedora need 3GB, you need to have 5GB. You will only need the 3GB as that the min required!

    If the GRUB Boot loader is edited properly, one can easily uninstall Linux. The best way to understand this in Windows, is type "msconfig" in the run prompt.
    On the pop up, click the "boot" and that this the Windows boot loader. If Linux was installed prior to Windows, linux would be listed there.... Now since most of us install Linux at a later stage, we use the boot loader of Linux, which is GRUB

    I remember before, my brother who installed Windows 7 in our old computer, also installed ubuntu. So far it looks good. So I think using two OS in the same computer is fine.

    While it is possible, a lot of people make the mistake if trying to run them both, and something that isn't possible at the same time.

    If it was ran at the same time, may I know what will happen? I have no idea since my brother, so far, never mistakenly running it at the same time.

    That's what I'm saying, as far as I know it isn't possible. When the device starts up it will start up under the original OS. You can then change it so the next time it starts under a different one, but not both.

    I am actually using two operating system in my computer, a laptop, because each one has many characteristic that are positive and many that are negative. I am still using Windows 7 for my job, because is more compatible with the most of programs, problems are a lot but a lot of people know how to solve them quickly and that's one of the positive points of using windows, although one of the things that I do not like is that you have to pay for everything, programs, licences and better experiences.

    The another operative system that I use in my computer is Linux, specifically, Ubuntu. This system I use it mainly for purpose of entertainment because everything is free. Has a great community which gives support in case of troubles no matter where you are. The bad thing is that is not compatible with most of professional programs but user have made efforts to make and create programs like those and give them to us for free. Ubuntu is faster than Windows, that is what I like the most.

    Okay. Thanks for explaining anyway. I kinda missed seeing some of the words and ideas or words just popped up at my mind. May I ask something? Do I have to save the two operating systems in the same drive? Or make a partition and save it in the other one? Thanks in advance.
