How can I remove the XP dual boot option ?

Ok, so this week-end I tried adding a HDD on my XP machine.
This HDD had 2 partitions on it (from a previous XP install on another PC) so I used the XP install CD to basically delete them and create a single partition on it (that's the only way I knew how to do it).
However, while doing that, it ended up creating a dual boot config so that now, when I start my PC, I have to chose which OS to start:
1) The regular XP install (which works fine)
2) The one that never got installed on the new HDD since I only partitionned it.

How can I remove that dual boot option so that it only boots on the correct HDD ?

    1 thing I should mention is that at the dual boot screen I get 2 options:
    Microsoft Windows XP Professional
    Microsoft Windows XP Professional

    The default one is the first and this is the "new" HDD that doesn't have XP on it.
    I need to select the 2nd XP Pro install to boot to my "regular" XP.
  7. OK now I'm a bit confused, so let me tell you this:

    you need to remove one of these entrees

    multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect


    or

    now normally I would tell yo to delete the second line since your default normally is the one that is working, but in this case you are saying its the second option.

    so I leave it to you to decide which to remove.

    but before you do any editing back up your boot.ini as boot.ini.bak and leave it in your root directory, for example if your root drive is "C" then you want to put the back up file next the original in C:\boot.ini.bak.

    if you choose the second line then make sure to make your default look like this:

    Quote:
    default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS


    no change is needed if go with the first line ;)
  8. all that I know is that at the dual boot screen, if I don't do anything, it boots on the wrong disk (says something like file missing etc...).
    since the default seems to be:
    default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS

    I guess this is the one I should delete....

    by the way, you tell me to make a backup, but where is the original boot.ini file located ?
  9. if you read my last post then you will see I told you to save boot.ini.bak in the same directory as the original.

    the original being boot.ini, which resides in the root of your drive.

    so if your drive letter is "C" then you would find boot.ini in C:\boot.ini

    now once you back it up as boot.ini.bak then go back to startup management window and edit your boot.ini to look like this:

    Quote:
    [boot loader]
    timeout=1
    default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
    [operating systems]
    multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
  10. Ok, i'll try that - I'll let you know how it goes.
  11. besure to save teh backup first, if anything goes wrong we will need to use it ;)

    don't mean to be rude but you do know what you're doing right ? :wink:
  13. I know what I'm doing, but they are based on the info you have been giving ;)
  14. well, it looks like that did it :D
    thanks a lot for your help !
  15. looks like you gave me the right info ;)

    delete your old boot.ini.bak and make a new bakcup file based on the current boot.ini you have ;) be sure to delete only the backup file(boot.ini.bak) and not boot.ini itselft

    it was a pleasure and good luck ;) :)

    will do - but to keep on the original discussion about the location of the boot.ini file, I do not see such a file in c:\ (even with the "show all files" options set)
    are you sure it's in c:\ ?
  17. did you also uncheck "hide protected operating system files (Recommended)" ?

    ok..it's official, i'm an idiot :D
    thanks a lot for all your help - new boot.ini.bak has been created.
  19. lol you are no idiot, everybody misses that one the first time around ;)

    OK so now if ever you have a problem with your boot.ini file you have a backup for it which you can easily reach with recovery console ;)

    its been a pleasure and good luck ;)
