Computer running Windows 8 and want Windows 8.1, can only be upgrade it through the Windows Store. And if you got multiple Windows 8 computers, then each computer will need to download the same upgrade individually, which results in waste of time and for some it might be a issue if they have a bandwidth cap from their ISP. After looking up on the internet, I've found a nice workaround (credit to the person figured it out), and I'll share it with you here. Before getting started, you will need a Windows 8 Product Key. Computers with Windows 8 preinstalled, the key is inside the bios. These key may or may not work, but you can still try it out. To extract the key out, use a Key viewing utility, like KeyFinder or other similar programs. 1. Go to Microsoft's Windows 8 Upgrade site http://windows.microsoft.com/en-us/windows-8/upgrade-product-key-only 2. Download and save both setup (Install Windows 8 and Install Windows 8.1) files to your computer.
3. Go to the location where the files are saved. 4. Run Windows8-Setup and let it load
5. Type in your Windows 8 Product Key
6. Setup will analyze the key and then begin downloading.
7. Once it starts to download, click on the X on the top right corner and cancel it (no need to finish downloading).
8. Run WindowsSetupBox
9. Windows 8.1 will automatically beginning downloading. This may take a while so be patient
10. After it's done downloading, it will provide you with 3 options
11. From here on, you can create a ISO media, a USB bootable media or run from your Desktop. For ISO media, setup will ask for a location to save the image. After that, burn it to a blank DVD. 1. Select Install by creating media and click Next
2. Click on ISO file and click save
3. Save to a location and label the iso file
4.Setup will being creating a image
5. Image creation complete
6. Go the location where the ISO image is saved and right click to open up Window's image burning utility.
7. Click burn to start burning from ISO to a blank DVD media
For USB media, setup will ask for a USB flash drive of at least 3GB. And setup will automatically create the USB media for you. 1. Click on Install by media
2. Click USB flash drive, then click next
3. Insert a USB flash drive
4. Format USB flash drive
5. Creating Windows 8.1 on a USB flash drive
6. USB media complete
Note: Backup data first if there is any on the USB drive. Product key is made up for this tutorial, it's not a real key. The version being downloaded corresponds to the product key that was used Windows 8 Professional key = Windows 8.1 Professional Windows 8 Core key = Windows 8.1 Core Setup also looks at the platform your system is currently running. Current OS is 32bit = Setup will automatically download Windows 8.1 32bit. Current OS is 64bit = Setup will automatically download Windows 8.1 64bit.
I am trying to install windows 8.1 onto a partition on my drive, I already have Linux installed on another partition. When I try to install windows it says something along the lines of windows cannot install on mbr drive and needs to be gpt however I looked on Linux using gdisk and it confirms that the drive is already gpt. Any ideas ?

Windows can boot off GPT drives only via UEFI, without CSM (ie. not in BIOS-compatibility mode). If you have a GPT drive and want to boot via CSM, you're out of luck.
Mercruiser 5.7 manual pdf. You also have to boot the installation media using UEFI in order to install to a GPT drive. Otherwise, installer will refuse to continue (as the resulting installation would be useless anyway).
If you're already booting with UEFI (non-CSM), then your installation media may be borked. To create a proper one, you'll need a Windows 8.1 ISO file which you can download from Microsoft for free. You can either burn that ISO to a DVD or create a bootable USB flash disk using Rufus. Make sure to choose Partition scheme: GPT and Target system: UEFI (non-CSM).
If you're booting Linux via CSM, then you'll either have to convert disk to MBR (the hard way) or configure Linux to boot via UEFI (the hard-but-less-risky way). It will most likely involve chrooting from a live media and installing a package that enables GRUB to boot from UEFI. It's possible (I did it on Ubuntu), but I don't recommend it unless you're familiar with basic Linux boot internals or want to spend a few days learning. And don't forget to make backups.
