  1. I just reformatted my computer to fix and unrelated problem. Anyways when I start my computer now the os choice pops up and gives me 10seconds to choose an os. The one labeled windows xp home edition is the one works normally. There are however to more options, Previous Operating system and Install/upgrade to windows xp. How do i get rid of these extra options? Please help me out.

    Click on Start>Run and type msconfig > OK

    Click on the BOOT.INI Tab and copy and paste whatever is in the box.Then some of the experts will tell you what you have to delete.

    it wont let me copy and past so here is wat i see

    [Boot Loader]
    [operating systems]
    multi(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect /NoExecute=OptIn

    C:\ = "Previous Operating System on C:"

    C:\$Win_NT$.~BT\BOOTSECT.DAT = "Windows XP Installation/Upgrade"

    OK. Here's where I leave it to the experts, but it looks like a very unusual BOOT.INI to me.


    OK Heres mine:

    [boot loader]
    [operating systems]
    multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect /NoExecute=OptIn

    But my OS is on C: drive. I don't know which one you want to leave so better wait for someone more knowledgeable turns up. BEWARE: If you edit the BOOT.INI the wrong way you could make your computer unbootable.

    It works like this:

    [Boot Loader]
    Timeout=5 <-obvious
    Default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS <- your default OS same as the 1st choice below the [operating systems] section
    [operating systems]
    multi(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect /NoExecute=OptIn <- default

    C:\ = "Previous Operating System on C:" <- choice #2

    C:\$Win_NT$.~BT\BOOTSECT.DAT = "Windows XP Installation/Upgrade" <- choice #3

    so, just delte choice #2 and 3 from the file and you should only see the default OS choice, then rightclick "my computer" -> properties -> advanced -> startup and recovery -> turn off "show list of operating systems"
