Dual Boot Windows 7/ Windows 10 - UEFI

[cloves]

Hi all,

I got a new laptop. It is UEFI. I want to have multiple partitions. 1. Windows 10 2. Windows 7 3. Another Windows 7 Install or Windows 10

Created slipstream ISO of both Windows Pro x64 and Windows 10 Home x64, with updates and drivers from lenovo.

Deleted all partitions on the HD, installed Windows 10. Then in the UEFI bios, disabled secure boot and enabled legacy mode with uefi as first option.

Then stuck in my Windows 7 iso and booted. I get to the installing windows prompts and then I get a "Load Driver" pop up. Not sure what driver it is asking for. Laptop has x2 usb ports and x1 usb 2 port. I have the usb in my usb 2 port.

No clue what to do now.

Is it possible it requires a driver to access a SSD drive or a chipset?

See what type of HDD and chipset you have, download any drivers available for windows 7, extract them on a usb and try pointing the setup there.

Give us your Lenovo model specs.
If you installed Win 10 under UEFI then switch to Legacy, Win 10 probably wont boot.
If your Windows (7 and 10) are 64 bits, you should install Win 7 under UEFI. As Win 7 isn't compatible with Secure boot, you did right disabling it.
New MB has only USB 3.0 ports. If you don't have mouse when you launch win 7 installation confirms that you need USB 3.0 drivers. You also have to load the sata drivers. Please confirm.
I can guide you though your Win 7 and Win 10 installation once you give us your specs.
