Burn a disc and use your key (on your pc).
You might be missing some necessary files which are located in the system32 directory. If Windows wont Load, try pushing F8 after starting it and run a Restore or Recovery
Mine has suddenly started doing this too. A required Microsoft Windows system directory, the Windows System32 directory is often located in either C:\Windows\System32 or C:\Winnt\system32. Often many Microsoft Windows error messages will contain the system32 directory because many of the system files Windows uses to run are stored in this directory. By itself the System32 directory will not cause any errors unless it is missing of course. If you are getting an error with a file in the System32 directory search for that file. No error message, it just pops up and has to be 'closed'
Use windows update, it will automatically locate missing drivers (sometimes it does not work).
windows xp automated system recovery (ASR) Note: You can use recovrey console as well as windows repaire. if any file missing.
if you have original windows 7 disc, you can reinstall it if you have recovery windows 7 disc, you can fix it
Put your windows disk in the CD drive and the system should boot from the CD drive. Or from the dos command line enter the following command say your CD drive is "d" and your hard drive is "c". expand d:\i386\command.nt_ c:\windows\system32\command.ntfor windows xp or ntexpand d:\i386\command.co_ c:\windows\system32\command.com for rest of windows ver.
In my case Autoexec.nt was missing from the C:\WINNT\System32 directory. Looking in the C:\WINNT\Repair directory I found that Windows had automatically made a backup copy of Autoexec.nt, so I just copied this into C:\WINNT\System32 and the problem was fixed.
I think you mean C:/WINDOWS/System32/mtsalvp.dll The directory C:/WINDOWS contains the operating system files, and System32 is an especially dangerous folder to mess with. If this file is missing or damaged, you can fix it by using your original Windows install disks. They would have come with your computer. If this isn't your problem, add some more information below my answer and I'll try to help more.
You need to repair or reinstall the operating system. Also it depends on file which is missing. Some are files are not important as others. Missing system files might indicate that you have a virus/trojan/malware on your computer.
The error indicating that the script "C:\Windows\System32\boot.vbs" cannot be found typically suggests a corrupted or missing file, which can prevent the system from booting properly. To resolve this issue, you can try running the Startup Repair tool from a Windows installation media or recovery drive. Additionally, booting into Safe Mode may allow you to access the system and perform repairs, such as restoring the system to a previous point or replacing missing files. If the problem persists, consider seeking professional technical support.
It's VERY hard. Only way is software.
The error "'reg' is not recognized as an internal or external command operable program or batch file" typically means that the command-line tool is not found in the system's PATH environment variable. To resolve this, ensure that you are using the command prompt with administrative privileges, as some commands require elevated permissions. If the issue persists, check that the Windows Registry Editor (reg.exe) is present in the C:\Windows\System32 directory, and if not, you may need to repair your Windows installation or restore the missing file. Lastly, verify that your system's PATH variable includes C:\Windows\System32.
