Windows 10纯净安装失败并陷入启动循环（无管理员账户）求助

Hey Kimberly, sorry to hear your HP Windows 10 Home laptop got stuck in that frustrating "Just a Moment" loop after resetting it post-virus. Let’s walk through some practical, tested fixes that should get your system back up and running:

1. 先执行恢复模式下的核心命令修复 #

Since you already got into Command Prompt via recovery mode, start with these critical boot and system repairs:

• First, identify your system partition:
  diskpart
list volume
  Look for the small (usually ~100MB) FAT32 volume labeled "System", note its drive letter (e.g., D:), then exit diskpart:
  exit
• Fix the boot records:
  bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
  If you get "Total identified Windows installations: 0" when running bootrec /rebuildbcd, try manually rebuilding the BCD:
  bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /rebuildbcd
• Repair corrupted system files:
  If you can access your main system drive (typically C:), run:
  sfc /scannow /offbootdir=D:\ /offwindir=C:\Windows
  Replace D: with your actual System partition letter, and C: with your system drive letter if it’s different.

2. Skip the OOBE setup (the most common fix for "Just a Moment" loops) #

That endless "Just a Moment" screen almost always happens during the Out-of-Box Experience (OOBE) setup. Here’s how to bypass it:
In recovery mode’s Command Prompt, launch the Registry Editor:
regedit
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE
Right-click in the right pane → New → DWORD (32-bit) Value, name it BypassNRO, set its value data to 1, then close regedit and restart your laptop.
When it boots back up, you’ll see an option for "I don’t have internet"—select that, and you’ll be able to skip the forced network setup and finish the OOBE process normally.

3. Try an alternative reset with installation media #

If the above doesn’t work, use a Windows 10 installation USB to reinitialize the system:

• On another Windows PC, create a Win10 Home installation USB (make sure to match your version)
• Plug it into your HP laptop, boot from the USB (press F9 during startup to select boot device)
• On the install screen, click "Repair your computer" → "Troubleshoot" → "Reset this PC"
  First try "Keep my files" (even though you wanted a clean install, this can avoid OOBE bugs)
  If that fails, go for "Custom: Install Windows only (advanced)"—delete your old system partition, create a new one, and install a fresh copy of Windows.

4. Check HP-specific BIOS settings #

Some HP laptops have BIOS configurations that conflict with Windows reset:

• Restart your laptop, press F10 repeatedly to enter BIOS setup
• Look for "Secure Boot" and toggle its status (if it’s Enabled, switch to Disabled, or vice versa)
• Check "SATA Mode"—ensure it’s set to AHCI (some HP models default to RAID, which can cause reset issues)
• Save changes (usually F10) and restart, then try the reset or repair again.
