However, there is only one disk that I know of that can help to perhaps get you back in and that is a Kaspersky Recue Disk but it can take a number of hours for it to scan the system - it really depends upon what caused the machine not to boot.
I can't remember if you need to change the boot order for it to boot up with that disk, but you can give it a try if you like.
I have my laptops set to check the DVD and USB drives before the HDD should I need to recover mine.

Use the Graphics option and you will need to Ethernet connect so that it can update its Definitions.
The first time I used it on mine, when it completed, it initiated a chkdsk /f and the second time, when I took the disk out on completion - power shut down - it started up okay when I switched on.
Before you try that, see if a cold boot will get you back in.
If the battery is accessible, remove that and the AC then press the power button for approx. 30 secs and try it again.
When you said those steps didn't work - did you mean that you were able to get into the BIOS ?

Sorry I wasn't clear, I bought this laptop off ebay but the password for the bios was changed so there is no taking it to their IT.
However I can choose what I boot from not boot order.
When I tried the cd \windows\system32\config it told me the path didn't exist.
Trying the kaspersky now.

I'm not sure where you are trying that cmd but if you can boot with other media then it must already be set to check those first before the SSD/HDD.
Good luck with Kaspersky.

Sorry for being so unclear. I'm able to hold f9 for boot options and select the boot device.
As for the cmd, I'm able to get to the windows advanced options without using the media installation usb boot. so I don't need it to access it.
Edit: I've got kaspersky running now!
Thanks man, I'm running the scan now so by the time I'm back it'll be done.
I also since I love the tweaking repair program have backups to my registry so if this fails, how would I go about using it?
Thanks so much.
If I do get it working, I will of course write a detailed reply about the process for future users.
Boggin:
To use the registry back ups in Windows Repair, boot into Safe Mode with Networking and open the program and click on Backup Tools.
Click on Restore under Registry Backup then on the Restore Registry tab.
You will then need to use the dropdown to click on the backup you want to restore with but do not select one that is too old.
You can then hit the Restore Now button.
A word of caution though - under no circumstances run Windows Repair v4.0.10 on Windows 10 as there is a bug in it that will take out the MS Solitaire Collection.
Shane, as far as I know is working on a fix for it but for the moment once it's gone - it's gone and only a system image will restore it.
A restore point or the registry back up restore won't.
I'm not sure if this article will help you with the password problem - https://www.iseepassword.com/reset-windows-10-password.html

I can't get into any type of safe mode is the only issue, was hoping I could drag and drop from kaspersky's registry editor.
I have a back of my registry from an outdated windows repair program so it shouldn't have the solitaire collection issue but even if it did, I wouldn't mind.
I really don't think malware is my issue but I ran it while I was out to only find out the data base was corrupted so I'm going to try to reinstall the iso and hopefully get it running tonight before bed.
As for the password I know my password, just not the bios password but I don't need to use bios to change boot device so it's fine.
