Creating a partition from one hard-drive and installing Windows 7?

[Aqua123]

Alright this is something that has been bugging me a lot recently. Since I've gotten my hands on my Asus windows 8 laptop last Christmas, I've always wanted to install Windows 7 on it. Found out about Virtualbox the other day and installed it with windows 7. Everything worked out and my fear of messing up my new laptop was gone. However my laptop is loaded with some pre-configured apps that are specifically designed for my Asus laptop. I didn't want to lose some files and those apps so I wanted to create a partition from my main hard-drive (Disk 0) and install windows 7 on there. I wish to use dual boot and switch to either OEM with ease. When I try to install windows I get the error "This isn't a GPT drive, which could cause the installation to fail. Would you like to continue?" Around those lines. Well after a few hours of fooling around I decided to give up and continue with the installation. When my laptop loads now, there's two options windows setup and windows 8.1. Windows setup doesn't go through and gives me an error.

Two questions now, how do I install two operating systems on one hard-drive by using partitions possibly?

And

How do I get rid of that windows setup boot up screen now? It's getting annoying :/.

I'll appreciate any sort of feedback/advice.

Thank for reading guys!

Go to the Boot button in msconfig and see whether you can get rid of the boot entry there. Else you can use EasyBCD to get rid of it.

You'll need to disable Secure Boot in BIOS Setup on a Win7 PC in order to install Win7, and possibly enable some level of CSM or Legacy support. Let us know what settings choices are available.

Then boot the Win7 installation media as a UEFI device using the F12 BIOS Boot Menu key.

If using a flash stick installer format it with Option One of http://www.eightforums.com/tutorials/15458-uefi-bootable-usb-flash-drive-create-windows.html

Enabled CSM and disabled secure boot mode, and it installed like a charm. Keyboard, mouse, and monitor all work. It's going to take me a while to find the drivers for wifi, video card, etc. But I'm up for it. Should I revert those settings in the BIOS now? Or do I have to keep them as is when I want to use Windows 7? Thanks for the help!

Stick as closely as possible to these same steps for a Clean Reinstall - Factory OEM Windows 7 , especially how drivers are handled in a driver-complete OS which are printed in red.


You shouldn't have to search for most drivers but if after enabling Automatic Hardware Updating and running all rounds of Important and Optional Updates there are still any missing in Device Manager, post back the listed name and Hardware Identification (which can also be googled for a Win7 driver) and we'll help you find it.
