recovery console problem

Posted on 2005-05-01
Last Modified: 2010-04-14
when i selected R to use recovery console on my win2000 pro PC, it bypassed the options and goes directly to c prompt. for that reason i was unable to execute any commands b/c of "access denied" messages. i know it requires a password and that recovery console has to display the options such as choose an OS (pick a number) then prompts for password. i tried to shut down then power up several times but the RC still bypass the options. the hard drive is in good condition and checked that the drive is accessible by the win98 bootable floppy and also used BIOS setup to check that it can detect the HD. my purpose for using RC is to restore the missing ntoskrnl.exe file. please advise.

    There are two possibilities here; let's start with the better one:
    You had the "Recovery console: Allow automatic administrative logon" in the local security policy enabled. The "Access denied" message comes up when you're trying to access a directory outside root, cmdcons, %systemroot% and its subfolders (or removable media).

    If together with the logon policy you enabled "allow floppy copy ..." as well, you need to enable access by setting the allowallpaths variable in the recovery console:

    Either way, you should be able to copy the ntoskrnl.exe file from the %systemroot%\driver cache directory or copy/expand it directly from a CD (with the ntoskrnl.exe version matching your service pack).

    The second one (which is actually more probable, I'm afraid) is that you're starting the console from CD, and that your W2k installation can't be verified, due to a corrupted disk or MBR (You should still be able to run the fixboot and fixmbr commands):

    I actually don't think it's the "missing" kernel file. Seems like the complete installation is inaccessible, that's why you can't even use the recovery console.
    If you have another machine, try to put the drive into this one and see if you can access any files on the drive. If so, backup anything of importance.
    Next best thing to try might be a repair installation (with an install medium that matches your service pack level).
