NTFS partition improperly dismounted

Running WinXP on a laptop (so drive very difficult to remove). Machine continuously reboots giving "isass.exe error: While trying to enter or update a password this return status indicates that the value provided as current password is not correct". I cannot access the Recovery console since the laptop did not come with a master XP install disk. I can boot on a Win98 boot disk, but it won't let me run chkdsk.

I also tried the Partition Magic recovery disks, it finds the partition and says it is improperly dismounted, but won't let me fix (button is grayed out). It advises running chkdsk, which I can't do. It will not let me convert to Fat32 either, since it encounters the dismounted error.

Just signed up for E-E and trying it out, so only have 75 points thus far to award, sorry.

When you get to the login can you to this Ctrl+Alt+Delete and see if you can get in?

Have you tried booting to safe mode

In either case if you can get in then

Booting into Safe Mode, Last Good Config, etc. all do the same thing: isass.exe error and then reboot all over again. I never get to the login screen.

I did go to the MS site for the XP Setup Boot Disks and have created them. They install up to the last disk (#6) and then I get a blue screen with message "UNMOUNTABLE_BOOT_VOLUME" and advises me to check hardware. No new hardware has been added.  Also

"STOP: 0x000000ED (0x822FA3A0, 0xC0000013, 0x00000000, 0x00000000)"

There is something wrong with the disk or the files system. Use one of those utilities I posted in a prior coment.

After trying an XP Home upgrade CD a friend loaned me, I was finally able to access the Recovery Console. However, it asks me for the administrator password. I tried both the password I used for my personal profile (which I believe had admin priveleges) and also hit enter (no password). It did not accept either one.

Just enter a blank password for the built in Admin account

See if this helps

Most of these are bootable floppies that give you a backdoor to the SAM registry hive and allows you change the admins password.

Free stuff

This is a utility to (re)set the password of any user that has a valid (local) account on your NT system, by modifying  the crypted password in the registrys SAM file.
image files
http://home.eunet.no/~pnordahl/ntpasswd/bd030126.zip  Bootdisk image, date 030126
http://home.eunet.no/~pnordahl/ntpasswd/sc030126.zip - SCSI-drivers (030126)
The unzipped image (bdxxxxxx.bin) is a block-to-block representation of the actual floppy, and the file cannot simply be copied to the floppy. Special tools must be used to write it block by block. For Dos, win95/98 & NT, use rawrite2.exe or some other imagewriter:
http://home.eunet.no/~pnordahl/ntpasswd/rawrite2.zip - DOS Program to write floppy images.

http://home.eunet.no/~pnordahl/ntpasswd/cd030126.zip - Bootable CD image with same version and drivers as floppies above.

Change administrator password on NT/2000, without knowing it!!! Bootdisk...

Run it to create a boot floppy then follow the instructions. If you choose to do this then you are doing this at your own risk. Just change the admin pw and login then change the account pw's that you desire.

Make sure you have a floppy disk in the floppy drive and let the program create the boot floppy. Now restart the machine a let it boot from the floppy. Now follow what it instructs you to do.

Use it like a bootdisk.

NTFS/FAT Boot disk for password recovery/reset

NTAccess can replace the administrator password of a Windows XP, Windows NT or Windows 2000 system by rebooting the computer with a special set of boot disks or CD-ROM (XP only). This is useful if you forgot the administrator password and cannot access the Windows XP/2000/NT system.

ERD Commander

When your server or workstation won't boot, you need ERD Commander 2002. ERD Commander 2002 boots dead systems directly from CD into a Windows-like environment. You'll have full access to the dead system's volumes, so you can diagnose and repair problems using tools located on the ERD Commander 2002 Start menu. And you'll have built-in network access to safely move data off of, or on to, the dead system. With ERD Commander 2002 you can repair a system quickly and easily, saving you time and rescuing your critical data.

Or you could, if you have a FAT32 file system, just boot to a Win98 bootdisk and rename the SAM file (registry Hive) in the C:\WINNT\system32\config folder to something else. Of course this will remove all accounts on the system and you will need to rebuild them. If you are using NTFS then boot to the Win2000 CD and do this from the Recovery console.
