Windows 10: Windows 10 Live USB getting error irql not less or equal during fresh installation of...

Hello. I recently got a new cpu and hard drive for my laptop, a toshiba satellite L635. I formatted the drive on my other windows computer to NTFS on my other windows computer, and wanted to do a fresh windows installation on the laptop. I downloaded the iso and created a live usb to do the installation like normal, and all the correct hardware shows in BIOS. However, when booting from the usb, it says "irql not less or equal", EVEN IN SAFE MODE, during the initial bootup to try and install windows. I do not know what to do at this point, it seems that it can't even boot in safe mode or safe m

IRQL NOT LESS OR EQUAL / KMODE EXCEPTION HANDLED at installation of Windows

Hi andy4117,

Thank you for posting your question in the Microsoft Community

1. Did you installed Windows 10 on this computer before?
   
2. Are you trying to install Windows by booting from the disc or USB?
   
3. When you says MBR – GPT, May I know the complete error message that you are receiving, when you are installing Windows?
   
4. Did you unplugged all the external device, apart from Mouse and keyboard?
   

Usually, IRQL NOT LESS OR EQUAL / KMODE EXCEPTION HANDLED errors are seen if there are faulty hardware, drivers or anti-virus programs. As you are trying to install Windows 10, you can try the steps to perform a Custom Installation
of Windows 10 by booting from a disc or USB.

IRQL_NOT_LESS_OR_EQUAL could be due to faulty hardware problem, faulty system service problem and KMODE_EXCEPTION_NOT_HANDLED could be due to Hardware incompatibility and Faulty device driver or system service
