Ubuntu 14.0 LTS USB LIVE无法定位Windows文件及Win10管理员账户锁定求助

Hey Joe, let's tackle this problem head-on—first we'll get your Windows files visible in Ubuntu Live, then fix that locked admin account. Here's the step-by-step breakdown:

Step 1: Locate & Mount Your Windows Partition in Ubuntu Live USB #

The most common reason Ubuntu can't find your Windows files is that the NTFS partition isn't mounted, or it's in a dirty state (from an improper Windows shutdown).

• Open the Terminal (find it in the applications menu or press Ctrl+Alt+T).
• First, list all your disk partitions to identify the Windows NTFS drive:

  sudo fdisk -l
  

  Look for a partition labeled Type: Microsoft basic data with a size matching your Windows drive (usually the largest partition, often /dev/sda2 or /dev/nvme0n1p2 if you have an SSD).
• If the partition shows up but isn't mounted, create a mount point and attach it:

  sudo mkdir /mnt/windows
  sudo mount -t ntfs-3g /dev/sdaX /mnt/windows
  

  Replace /dev/sdaX with your actual Windows partition (e.g., /dev/sda2).
• If you get an error about a dirty volume, fix the NTFS first:

  sudo ntfsfix /dev/sdaX
  

  Then try mounting again.
• If you still can't find the partition, check your BIOS/UEFI boot settings: ensure Ubuntu is booted in the same mode (UEFI or Legacy) as your Windows installation. Mismatched modes can prevent GPT/MBR partitions from showing up.

Step 2: Fix the Locked Windows Admin Account #

Once you can access your Windows files, we'll reset the admin password or restore the account using the chntpw tool (a utility for editing Windows registry files from Linux).

• First, install chntpw (you'll need to update your package list first for Ubuntu 14.04):

  sudo apt-get update
  sudo apt-get install chntpw
  

• Navigate to the Windows registry config directory:

  cd /mnt/windows/Windows/System32/config
  

• Run chntpw to edit the SAM file (which stores user accounts and passwords):

  sudo chntpw -u Administrator SAM
  

• Follow the on-screen prompts:
  1. Choose option 1 to clear the administrator password (this lets you log in without a password).
  2. If your account was accidentally disabled, choose option 2 to enable it.
  3. Save your changes (option q then y to confirm).

Step 3: Post-Fix Notes #

After making these changes, restart your computer and boot back into Windows. You should now be able to log into the Administrator account. Once logged in:

• Open the Registry Editor (regedit), navigate to HKEY_LOCAL_MACHINE\SAM\SAM.
• Right-click the SAM folder, go to Permissions, and restore the default permissions (ensure the SYSTEM account has full control, as it did before your changes).
