Windows 10: Cannot now boot into Windows 10

Hi All,

I have a Windows 10 PC. It did work and should do again. I partitioned the hard disk to install Windows XP so an old programme could get at LPT1. XP will not install - a problem with 'Devices' keeps giving the IRQL error. During the failed XP install, boot.ini was re-written so now the PC keeps trying to run up the failed XP. I need a boot.ini file that will access Windows 10 on C: drive, like this:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows 10, C:" /fastdetect
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows XP Professional, D:" /fastdetect

For my Windows 10 installation, how do I find the correct multi(0)disk(0)rdisk(0)partition(1) values? Whatever I do, Windows 10 is ignored in favour of Windows XP. I can boot from a 'Bart PE' disk so I can see the whole disk. I just can't boot into Windows 10.

Regards

Gary

Cannot boot into Windows 10.

Hi Sipchen,

Thank you for posting on Microsoft Community. We will assist you in resolving your issue.

I suggest you to perform startup repair from the Windows 10 installation disk and by following the steps from the link below.

Startup Repair is a Windows Recovery tool that can fix certain system problems that might prevent Windows from starting. Startup Repair scans your computer for the problem, and then tries to fix it so your computer can start correctly.

Startup Repair is one of the recovery tools in the System Recovery Options menu. This set of tools is located on your computer’s hard disk, and on the Windows Installation disc.

If you are on Windows 10, I suggest you to repair your computer by creating a Windows 10 Bootable media (i.e. USB or DVD) using
Media Creation Tool. Once you're ready with Bootable Media, follow the below mentioned
steps.

• Insert the Windows installation disc in the disc drive or connect USB media and then start the computer.
• Press a key when the message Press any key to boot from CD or DVD appears.
  
  If your PC does not detect the media automatically
  • During the restart process, read the screen for any instructions that explain how to interrupt normal startup and enter the basic input/output system (BIOS) setup utility. Most PCs use the F2, F10, ESC, or DEL key to begin the BIOS Setup.
  • Look for a tab in the BIOS Setup Utility that is labeled Boot Order,
    Boot Options, or Boot. Following the directions on the screen, use the arrow keys to go to the
    Boot Order, then press Enter.
    
  • Locate the CD, DVD, or USB flash drive (this might be called Removable Device) in the Boot list. Following the directions on the screen, use the arrow keys to move the drive up so that it appears first in the Boot list. Press
    Enter. The boot order sequence is now changed to boot from the CD, DVD, or USB flash drive.
  • Press F10 to save your changes and to exit the BIOS Setup Utility. Select
    Yes in the confirmation window. The PC will restart. Allow the PC to restart normally. The scan will take a few minutes and remove any malware that may be infecting your computer.
• Select a language, a time, a currency, a keyboard or another input method, and then click
  Next.
• Click Repair your computer.
• Click the operating system that you want to repair and then click
  Next.
• On the Choose an option screen, select Troubleshoot. Select
  Advanced options from the window and click on Startup repair
  option.

If the issue persist, I suggest you to perform System Restore
under Advanced Options and follow with onscreen instruction to repair your computer.

Hope this helps!

We are happy to assist you with any issues pertaining to Windows.

Thank you.

Hi, Yash.

Thank you for posting your query in Microsoft Community.

I understand your concern, and we in Community will try to help you in the best possible way.

I suggest that you try the steps below and check if issue persist:

Method 1:

• While at the black screen, try using CTRL+SHIFT+ESC to start Task Manager.
  
• If it becomes visible, try finding LockAppHost.exe on the Details tab of the Task manager and ending the task.
  

If this resolves your issue, then follow the steps below to repair the corrupted resolution.

Step1: DISM

Follow the steps to Run DISM Commands:

1) Press Windows + x on your keyboard.

2) Select Command prompt (Admin) to open Administrator Command Prompt .

3) In the Administrator: Command Prompt window, type the following commands. Press the Enter key after each command:

dism.exe /online /cleanup-image /scanhealth

dism.exe /online /cleanup-image /restorehealth



Step 2: SFC scan

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

To perform SFC Scan, refer to the below link:

https://support.microsoft.com/en-us/kb/929833

Note: Steps mentioned for Windows 8/8.1, will work fine with Windows 10.

Method 2:

If this does not work, use File, Run new task in Task Manager to start an Administrator CMD window. Use this to create a new administrator user with the following commands (changing “<password>” to something of your choice (choose):

net user test <password> /add

net localgroup Administrators test /add

This will give you a test user to try, which will confirm if the issue is user or system-specific.

Hi, suggest seeing post #29 here:
Dual boot XP on top of Windows 10 - Page 3 - Windows 10 Forums

 

Hi Dalchina,

No, that does not help. Windows 10 is on my PC. I just can't boot into it as the failed XP install overwrote boot.ini.

 

Starting with Windows Vista the Boot.ini file replace with BCD data store file.

You always install older versions of Windows OS first then install newest version of the Windows OS so the boot manager of the newest version of the Windows OS will boot older versions of Windows OS.

Please boot your computer with Windows 10 Setup Media and from Windows Recovery Environment start the Command Prompt.

Please type below commands into Command Prompt and press Enter key.

Following commands will repair Master Boot Record (MBR), Boot Sector and BCD Store.


Code: Bootrec /FixMbr Bootrec /FixBoot Bootrec /RebuildBcd[/quote] Reboot your system to see you can boot into Windows 10.

 

Hi Freebooter,

Thanks. I don't have a win 10 setup disc as the PC came pre-installed but, the PC I'm using now is also win10! Will a recovery disk from this PC be able to fix my older win10 pc?

 

Make sure they are same Windows 10 bit versions and edition.

If you're using a recovery drive created on Windows 10:

• Connect the recovery drive and turn on your PC.
• On the Choose an option screen, select Troubleshoot, and then select an option. If you don’t see the Choose your option screen, your PC might not be set up to boot from a drive. Check your PC manufacturer’s website for info on how to change your PC’s boot order.
  • Restore from a system restore point by selecting Advanced Options > System Restore. This will remove recently installed apps, drivers, and updates that might be causing your PC problems, but it won’t affect your personal files.
  • Select Reset this PC and then choose to keep or remove your files.
    
    If resetting doesn’t work, you can also Recover from a drive. This will reinstall Windows 10 (unless your PC came with Windows 8/8.1 and a recovery partition from your PC manufacturer, in which case it'll reinstall the version of Windows that came with your PC). It'll also remove your personal files, apps and drivers you installed, and changes you made to settings.

If you don't want to Reset or Recover your computer then follow my bootrec command instructions.

 

Hi FreeBooter,

You are a genius! I have several recovery/repair disks and found one that installed Bootrec. I ran your three commands:

Bootrec /FixMbr
Bootrec /FixBoot
Bootrec /RebuildBcd

WIN 10 PRO wouldn't load up first time so I used F8 and got to the 'safe mode' option. She booted up fine. This must have repaired/reset something as since then she has booted up into standard mode every time.

I have run System Mechanic Pro to clean up the system and all is good.

Many thanks for your help. MY PC has been rescued *Smile
