    OS on Drive L

    I did a reinstall (clean) of WinXP Pro on Drive O, forgetting that Drive 1 had an older, non-functioning XP backup. Discovered that the install went to the next available drive letter (L). Disk Management does not allow changes to the drive letter of the OS partiition, with good reason. No known repercussions until possibly today, when all Windows updates dowloaded but failed to install. Are they assuming the OS is always on C or is something else the likely culprit?

    No, it does not matter to udates which drive letter boot partition is assuming to. (Don't ask me why the partition where system files are is boot partition and the one where boot files are is system partition - see <A target="_blank" HREF=http://support.microsoft.com/default.aspx?scid=kb;EN-US;q100525>Definition of System and Boot Partition</A>)
    There is some other problem preventing upgrades to install. FYI see <A target="_blank" HREF=http://www.wopr.com/cgi-bin/w3t/showflat.pl?Cat=&Board=xp&Number=105554&page=0&vie w=expanded&sb=5&o=0&fpart=>this thread</A>

    As a follow-up on kalin's post:

    In XP, when you set up the operating system, it creates a "global variable" called %systemroot% that designates where the system partition lives. Any software that wants to know where Windows is installed will ask, and instead of getting %systemroot%, something to the effect of C:WINNT or F:WINDOWS is returned to the program, wherever the active installation lives.

    If your updates failed to install, try them again, perhaps in smaller groups - two or three at a time.
