What is the difference between gpt and mbr
Differences: 1. mbr supports up to 2T, while gpt is theoretically unlimited; 2. mbr supports up to four primary partitions, and gpt has no restrictions; 3. Win7 can only use mbr partitions, starting from Win8 Microsoft recommends that you use gpt; 4. gpt is started by uefi, and its compatibility and stability are not as good as bios mbr.

MBR Partition
MBR means "Master Boot Record", which was proposed by IBM in the early years. It is a special boot sector that exists at the beginning of the disk drive. This sector contains system information about the installed operating system and a small piece of code to boot the system. If you installed Windows, its startup information is placed in this piece of code - if the MBR information is damaged or accidentally deleted, Windows cannot be started normally. At this time, you need to find a boot repair software tool to repair it. In Linux systems, MBR is usually the GRUB loader. MBR. When a computer starts up, it will first start the BIOS system that comes with the motherboard. The bios loads MBR, and then MBR starts Windows. This is the startup process of mbr.
GPT Partition
GPT means GUID Partition Table, which is the "global unique identification disk partition table". It is another more advanced and novel disk organization method, a disk organization method that uses UEFI boot. Initially it was for better compatibility, but later it was widely used because of its larger supported memory (mbr partition supports up to 2T disks) and more compatibility, especially since all Apple MAC systems use gpt partitions. gtp no longer has the concept of partitions, and all CDEF disks are stored in a piece of information. It can be simply understood as a technology that is more advanced but not widely used enough.
The difference between the two
Memory support: mbr supports up to 2T, while gpt is theoretically unlimited.
Partition: mbr supports up to four primary partitions, and gpt has no limit. If you want to run multiple systems, mbr can have up to 4 but gpt has no limit.
System: Win7 can only use mbr partition. Starting from Win8, Microsoft recommends that you use gpt.
Others: gpt is started by uefi, and uefi is a later concept, and its compatibility and stability are not as good as bios mbr.

Introduction to win11 hard disk format mbr or guid
Dec 27, 2023 am 11:59 AM
Many friends encounter situations where they need to manually modify the hard disk format when installing win11, but they don’t know whether the win11 hard drive format is mbr or guid. In fact, both partitions are possible, but the installation methods will be different. Let’s take a look at them together. Let’s introduce it in detail. Win11 hard disk format is mbr or guid: Answer: Win11 hard disk format is both mbr and guid. In fact, win11 can be installed using both mbr format and guid mode. However, there are some differences between the two formats in terms of installation and use. The difference between win11 hard disk format mbr and guid 1. Installation 1. If we use a USB flash drive, we must use the mbr format when installing win11 in the pe system. 2. If you use w
The ultimate weapon for Kubernetes debugging: K8sGPT
Feb 26, 2024 am 11:40 AM
As artificial intelligence and machine learning technologies continue to develop, companies and organizations have begun to actively explore innovative strategies to leverage these technologies to enhance competitiveness. K8sGPT[2] is one of the most powerful tools in this field. It is a GPT model based on k8s, which combines the advantages of k8s orchestration with the excellent natural language processing capabilities of the GPT model. What is K8sGPT? Let’s look at an example first: According to the K8sGPT official website: K8sgpt is a tool designed for scanning, diagnosing and classifying kubernetes cluster problems. It integrates SRE experience into its analysis engine to provide the most relevant information. Through the application of artificial intelligence technology, K8sgpt continues to enrich its content and help users understand more quickly and accurately.
Should I choose MBR or GPT as the hard disk format for win7?
Jan 03, 2024 pm 08:09 PM
When we use the win7 operating system, sometimes we may encounter situations where we need to reinstall the system and partition the hard disk. Regarding the issue of whether win7 hard disk format requires mbr or gpt, the editor thinks that you still have to make a choice based on the details of your own system and hardware configuration. In terms of compatibility, it is best to choose the mbr format. For more details, let’s take a look at how the editor did it~ Win7 hard disk format requires mbr or gpt1. If the system is installed with Win7, it is recommended to use MBR, which has good compatibility. 2. If it exceeds 3T or install win8, you can use GPT. 3. Although GPT is indeed more advanced than MBR, MBR is definitely invincible in terms of compatibility. GPT and MBR areas
In-depth understanding of Win10 partition format: GPT and MBR comparison
Dec 22, 2023 am 11:58 AM
When partitioning their own systems, due to the different hard drives used by users, many users do not know whether the win10 partition format is gpt or mbr. For this reason, we have brought you a detailed introduction to help you understand the difference between the two. Win10 partition format gpt or mbr: Answer: If you are using a hard drive exceeding 3 TB, you can use gpt. gpt is more advanced than mbr, but mbr is still better in terms of compatibility. Of course, this can also be chosen according to the user's preferences. The difference between gpt and mbr: 1. Number of supported partitions: 1. MBR supports up to 4 primary partitions. 2. GPT is not limited by the number of partitions. 2. Supported hard drive size: 1. MBR only supports up to 2TB
How to determine whether the computer hard drive uses GPT or MBR partitioning method
Dec 25, 2023 pm 10:57 PM
How to check whether a computer hard disk is a GPT partition or an MBR partition? When we use a computer hard disk, we need to distinguish between GPT and MBR. In fact, this checking method is very simple. Let's take a look with me. How to check whether the computer hard disk is GPT or MBR 1. Right-click 'Computer' on the desktop and click "Manage" 2. Find "Disk Management" in "Management" 3. Enter Disk Management to see the general status of our hard disk, then How to check the partition mode of my hard disk, right-click "Disk 0" and select "Properties" 4. Switch to the "Volume" tab in "Properties", then we can see the "Disk Partition Form" and you can see it as Problems related to MBR partition win10 disk How to convert MBR partition to GPT partition >
GPT large language model Alpaca-lora localization deployment practice
Jun 01, 2023 pm 09:04 PM
Model introduction: The Alpaca model is an LLM (Large Language Model, large language) open source model developed by Stanford University. It is fine-tuned from the LLaMA7B (7B open source by Meta company) model on 52K instructions. It has 7 billion model parameters (the larger the model parameters, the larger the model parameters). , the stronger the model's reasoning ability, of course, the higher the cost of training the model). LoRA, the full English name is Low-RankAdaptation of Large Language Models, literally translated as low-level adaptation of large language models. This is a technology developed by Microsoft researchers to solve the fine-tuning of large language models. If you want a pre-trained large language model to be able to perform a specific domain
How many of the three major flaws of LLM do you know?

Science: Far from being an eternally benevolent and beneficial entity, the sentient general AI of the future is likely to be a manipulative sociopath that eats up all your personal data and then collapses when it is needed most. Translated from 3WaysLLMsCanLetYouDown, author JoabJackson. OpenAI is about to release GPT-5, and the outside world has high hopes for it. The most optimistic predictions even believe that it will achieve general artificial intelligence. But at the same time, CEO Sam Altman and his team face a number of serious obstacles in bringing it to market, something he acknowledged earlier this month. There are some recently published research papers that may provide clues to Altman's challenge. Summary of these papers
what is mbr
Jan 31, 2023 pm 02:55 PM
mbr has two meanings: 1. It means "memory buffer register", which is registered in the processor or central processing unit of the computer. The CPU transfers the stored data to and immediately accesses the storage; 2. It means "membrane bioreactor", which is A new water treatment technology that combines a membrane separation unit with a biological treatment unit.
