    Please Help...


    I've tried this among many other things, and nothing has worked. I continue to get "BootMgr is missing" error message. Can you help please?

    What kind of machine have you got?

    Do you have one of those 100mb partitions?

    Welcome to Windows Seven Forums.

    Can you post a screen shot of your disk management layout?

    Mine looks like this:

    You'll notice there is a small 100Mb partition at the beginning of Drive 0. It is this partition that should be active as it is the one that holds the master boot record.

    You could try this method. If it doesn't work at first, try again.

    Hi Seavixen,

    I don't know how he can do that - he can't get into windows.

    I was going to outline using 7 boot media - but caed seems to have lost interest.

    It's late here.

    Goodnight.

    It's early here and I was having trouble sleeping and thinking straight too.

    You're quite right of course, but perhaps he'll post back later.

    So I have tried this due to OS drive letters changing from C: to D: (for some reason) and now I can't even load system repair tools because it doesn't locate the OS in System Recovery Options window... I guess now I'll HAVE to reinstall windows, but how can I be sure the files that are (were?) on D: don't get deleted ?

    It did with me also.
    I booted using Hiren Boot CD in mini Windows XP.
    Disk Management.
    Removed drive letter for system partition.
    Assigned C letter to OS partition.
    Now windows booted OK !
    Try this.
    You can backup the files also.

    I basically used a Ubuntu Live dvd and pulled the files I needed to an external storage device, formatted the drive completely, can't install windows now... I chalk it up to beat up HDD
