Master boot record (MBR) is a type of boot sector at the very beginning of a computer’s hard disk. A MBR contains machine code to function as an OS loader, which is responsible for loading and transferring control to an operating system kernel software like the windows NT loader found in Windows NT-based operating systems, GNU GRUB used by Linux, etc. A GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical storage device used in a desktop or server PC, such as a hard disk drive or solid-state drive, using globally unique identifiers (GUID).
GPT fdisk (gdisk, cgdisk, sgdisk, and fixparts) and Gnu parted can create or check for the presence of a GPT. Windows Disk Management tool can create, resize, format, and delete partitions. It can also assign drive letters and mount points to local drives. It can read MBRs but does not understand GPTs too much.
The advantage that GPT brings is Longer partition names: A longer name simplifies work when you have dozens of partitions on one disk; More primary partitions: You’re no longer limited to creating only four primary partitions; Greater flexibility over where you place EFI System Partitions; 64-bit version of Windows can read/write NTFS file systems without requiring third-party applications; Support for drives larger than 2 TB; No worries about BIOS INT 13h support as BIOS INT 13h is not needed anymore with UEFI/EFI. If your motherboard uses UEFI/EFI instead of BIOS then you do not need MBR anymore.)
1. More Primary Partitions
With GUID Partition Table (GPT), the limit on the number of primary partitions on a disk is removed. This means that you can create as many partitions as you want on the disk without having to create extended or logical partitions.
2. Ease of Use
The big advantage that GPT has over MBR is that it is very easy to use. For example, if you want to create a new partition on a GPT disk, all you need to do is right-click on the unallocated space and select “New Simple Volume.” On an MBR disk, however, you have to go through a lot of steps just to create a new partition.
3. Boot-Time
Another advantage of GPT over MBR is that it has a faster boot time. This is because GPT disks are able to take advantage of the UEFI boot process, which is faster than the traditional BIOS boot process.
4. Support for Larger Drives
GUID Partition Table (GPT) disks can theoretically support drives up to 16 Exabytes in size. In practice, however, most computers can only support drives up to 2TB in size. Nevertheless, this is still much larger than what MBR disks can support, which is only 2TB.
5. Better Error Checking
GUID Partition Table (GPT) disks also have better error checking than MBR disks. This means that there is less chance of data corruption on GPT disks than on MBR disks.
How to Find Your Windows 10 Product Key
If you’ve lost your product key for Windows 10, you’re in luck! There are a couple of different ways that you can find it. In this blog post, we’ll walk you through each method so that you can get back up and running in no time.
Method 1: Look for the Product Key on a Sticker
If you bought your computer with Windows 10 already installed, then the product key should be on a sticker somewhere on the body of the device. It’s usually on the bottom or back of a desktop tower, or on the back or bottom of a laptop. If you can’t find it there, try removing the battery (if it’s a laptop) and looking for a sticker underneath.
If you still can’t find it, don’t worry! There’s another method.
Method 2: Use a Product Key Finder Program
If you can’t find your product key using Method 1, then you’ll need to use a third-party program to retrieve it. There are a couple of different programs that can do this, but our favorite is called Product Key. It’s free, and it works well. Just download the program and run it. It’ll scan your computer for installed programs and retrieve the product keys for them. Once it’s finished scanning, scroll down until you see “Windows License.” The product key will be listed under that heading.
And that’s it! Those are two easy methods for finding your Windows 10 product key. We hope this helped!
Conclusion:
Losing your Windows 10 product key can be a Pain, but luckily there are a couple of different ways that you can find it. In this blog post, we walked you through each method so that you can get back up and running in no time.
GUID Partition Table has many advantages over Master Boot Record including more primary partitions allowed per disk,… quicker overall boot time from computer start-up. Microsoft’s Disk Management tool natively understands how to work with GUID Partition Table drives making it much easier to use than with Master Boot Record drives … and increased maximum theoretical storage size limit per GUID partitioned drive up into the 16 Exabyte range!
