Hi vinashrawat,

You're dealing with Secure Boot and GPT (
GUID Partition Table) issue installing Win7 dual boot on Win10 machine

Microsoft Secure Boot is a component which began with Microsoft's Windows 8 operating system that relies on the UEFI specification's secure boot functionality to help prevent malicious software applications and "unauthorized" operating systems from loading during the system start-up process.

GPT is the abbreviation of GUID Partition Table. The widespread MBR partitioning scheme, dating from the early 1980s, imposed limitations which affected the use of newer hardware. Intel therefore developed a new partition-table format in the late 1990s as part of what eventually became UEFI. The GPT as of 2010 forms a subset of the UEFI specification.

You don't have to make a BIOS switch to have Win 10 and Win 7 as long as you disable secure boot (for both).

As Win 10 is installed as UEFI you must also install win 7 as UEFI. To do so, make sure you boot the win 7 installation disk as UEFI.

Prepare your system for dual boot:
- As things can go wrong, before you begin, make a full system image (been there, didn't do that, big mistake).
- Backup your data on another disk.
- Defrag Win 10 partition.
- Open Disk Manager and create a new partition for Win 7 (>60G).

Boot from Win 7 installation disk as UEFI, go to install, choose the created partition and proceed.
Once installed, open device manager and load the missing drivers.

Windows boot manager will be created with Win 10 and Win 7 option.

To boot Win 7 installation DVD as UEFI when you launch boot menu you're going to see
- CD/DVD boot (that is Legacy- MBR)
- UEFI CD/DVD boot (that is UEFI)

How to Dual Boot Windows 10 with Windows 7 or Windows 8

Happy Computing!

If the laptop came with Win 10, it's probably from new generation CPU / Chipset
In this case you must also add SATA and USB drivers to the installation disk

Please give us all Laptop specs

Your laptop uses a Kaby Lake CPU and internal graphics (Intel 620).
To install win 7 you have to:
- Disable, on BIOS, secure boot and fast boot.
- Shrink the C: partition to make space to install Win 7 (85G). Use Disk manager to do it.
- Add SATA and USB drivers to the win 7 installation disk. Read my tutorial Create a Windows 7 USB flash installation with new drives for new MB's
SIW2 has made an application to add the drivers to the installation disk. Update your Win 7 installation media.

When you have the Win 7 installation disk (DVD or USB flash disk) with the drivers added, boot it as UEFI, go to install and choose the partition you have created with Disk manager.

You don't have USB because you didn't do anything I've instructed.
Extract the kabyLake.zip drivers to a folder. Under win 7 open device manager and on USB ask for a driver update. Point to the extracted drivers folder.

Make sure you have no yellow alerts on device manager.
Did you installed the Intel graphics driver replacing the igdlh64.inf (see post #6)?
