If you’re planning on doing a clean install of Windows 10, you’ll need to know the difference between MBR and GPT, as well as how to find your Windows 10 product key. In this blog post, we’ll give you a short overview of each and show you where to find your product key.
GPT vs MBR has been a hot debate for some time now. GPT is the newer standard and is slowly replacing MBR. GPT is more reliable and efficient than MBR. GPT stands for GUID Partition Table and MBR stands for Master Boot Record. GPT is more advanced than MBR in a few key ways. GPT uses CRC32 for error checking while MBR uses Checksum. GPT also uses LBA48 addressing which helps to overcome the 4 GiB limitation on drives using MBR. GPT also provides support for RAID and hot-plugging, which are not possible with MBR. Some argue that GPT is not as compatible with older systems as MBR, but this is slowly changing as GPT becomes more widely adopted. In the end, GPT is the superior choice and is slowly becoming the new standard.
What is MBR?
MBR stands for Master Boot Record. It’s a small piece of code that’s stored at the beginning of a hard drive or SSD. This code contains information about the drive’s partition table, as well as a bootloader. The MBR was first introduced with IBM PC DOS 2.0 in 1983.
One of the benefits of using MBR is that it’s compatible with older operating systems, such as Windows XP. Another benefit is that it supports drives up to 2TB in size. However, one downside of MBR is that it can only support four primary partitions.
If you want to create more than four partitions, you can create an extended partition, which can in turn be divided into multiple logical partitions. However, this means that one of your primary partitions will be used for the extended partition, which may not be ideal if you want to use all four primary partitions for other purposes.
What is GPT?
GPT stands for GUID Partition Table (sometimes also referred to as Global Unique Identifier Partition Table). It was introduced in Intel’s EFI specification in early 2000s and is increasingly being adopted as the default standard for new computers. One of the benefits of GPT is that it doesn’t have the 4-partition limit like MBR does—you can have an unlimited number of partitions on a GPT drive. In addition, GPT drives can be larger than 2TB—they can actually be up to 16TB!
Finding Your Windows 10 Product Key
If you’re planning on doing a clean install of Windows 10 or reinstalling Windows 10, you’ll need a Windows 10 product key to activate it. Here’s how to find your Windows 10 product key and get started with the installation process.
First, if you have a physical copy of Windows 10, the product key should be on a label or card inside the box that Windows came in. In case you can’t find your product key, there are a few other ways to get it.
If you downloaded Windows 10 from Microsoft’s website, the product key should be in your email receipt. If you can’t find the email receipt, you can try logging into your Microsoft account and checking your order history.
If you bought a digital copy of Windows 10 from an authorized retailer, the product key should be in your confirmation email. If you can’t find the email, you might be able to sign in to the retailer’s website and view your order history.
Once you have your Windows 10 product key, head to Microsoft’s Download Windows 10 page and click on the “Download tool now” button. Run the downloaded tool and follow the instructions. When prompted, enter your Windows 10 product key and select which version of Windows 10 you want to install. The tool will then download and create installation media for you on a USB drive or DVD.
If you bought a retail copy of Windows 10 from Microsoft or from a retailer like Amazon, you should have received a physical product key in the package. If you bought a digital copy from Microsoft Store, it will be emailed to you and should also be saved somewhere safe like your Documents folder or Microsoft Account page. If you upgraded to Windows 10 from an earlier version of Windows for free, your product key should already be associated with your Microsoft Account and you shouldn’t need it until you reinstall or clean install Windows 10 at some point in the future.
Whether you opt for MBR or GPT depends on your needs and preferences. If compatibility with older operating systems is important to you or if you want to use all four primary partitions, then MBR is probably your best bet. However, if you need more than four partitions or are working with very large drives, GPT might be a better option. Whichever route you choose, just remember where you put your product key!
