This is more of a question of what I can do at this point. Being in GeekU for a while, I have been infecting a computer (that has nothing important on it), and I've come upon one particular little nasty that I have analyzed. It looks like this has several effects, including this time, not allowing me to enter into any account. What happens is that when I boot, I get to the welcome screen, and logs out. So, now I'm at the login screen, and when I log in, it says "logging in..." for a second, before the screen blinks and says "logging off..." to return to the sign in screen. I was wondering, is there a way to have something like CHKDSK to run on boot to fix any errors that this nasty may have caused? Do you think there is any way to get the computer to boot back in normally?

P.S. Safe mode also doesn't work, whether I go into the Administrator account, or my own regular user account. If there is nothing I can do...just let me know, and I'll wipe the drive clean and start over. Thanks for any help! :whistling:

to repair the ntldr (the ntldr is the boot loader) and the ntdetect.com (the ntdetect.com is responsible for detecting basic hardware)

fix you will need a Windows XP CD.
- stick the Windows XP CD in, and boot your computer from the CD
(once you have booted up, you will see a blue screen)

click: R
(To go into the Recovery Console)
- type: password
(if you don’t recall setting a password for the Admin, try leaving it blank then hit enter, if you get an error, that means that there was a password. You will need this password to continue)

Once in the recovery console,
type: copy D:/i386/ntldr C:
(note my CD Drive is letter D: so change this to whatever your CD Drive is and my Windows is on C: so change that drive to whatever your Windows is on):
- press: enter
( if it asks you if you want to replace a file, say yes)
- type: copy D:/i386/ntdetect.com C:
- press: enter
( if it asks you if you want to replace a file, say yes)
Then Reboot.

OK, after the comp is posting again

to delete an invalid bootpath:

run command
- press keyboard buttons: winkey + r button
- paste this: msconfig
- press: enter
- click tab: boot.ini
- click button: check all boot paths
(computer checks the boot paths and removes invalid ones)
- restart the computer
