What are the advantages and disadvantages of using UOS+MBR for UEFI+GPT and UEFI+MBR? Full of dry go

Welcome everyone to my blog! Today I have prepared for everyoneoneAn exciting article, hoping to arouse everyone's interest and gain some insights.

System Restore, maximum capacityabsenceBy turning off UEFI and converting the hard drive from GPT to MBR, we can completely destroy the advantages of UEFI+GPT and return to the outdated and outdated system installation and operation mode of BIOS+MBR. one. GPT can use hard drives larger than 2.2T, MBRabsenceOkay.

Supports a maximum volume of 18 EB (1EB=1048576TB). 2. GPT can support unlimited partitions. Microsoft's current limit is 128 Linux, ubuntu, and macos can support this partition format. MBR can only support up to 4 primary partitions, and more than 4 secondary partitions can only be usedThrough logical partitioning.

3. The GPT partition disk has a backup Partition table to improve the integrity of the partition data structure.

5. UEFI+GPT supports Secure Boot by protecting pre boot or pre boot processes to resist bootkit attacks, thereby improving security. All technologies that load earlier than the Windows kernel at boot time and achieve kernel hijacking can be called bootkits.

6. UEFI BIOS can operate a graphical interface with a mouse,absenceThen there is the dry blue background and white text in English (proposed by Intel to replace BIOS). The superior features of UEFI include operability, security, compatibilityThe system boot file of BIOS+MBR with scalability can be located in the same location as the system file1Partitioned.

Root directory, also possibleabsencetakeSystem files are the same as1Partition, as long as the partition where the system boot file is located is the active primary partition, the operating system can be started; UEFI+GPT can only place the system boot files on the ESP partition, and the operating system must be on another primary partition, which means UEFI+GPT forces the system boot filestakeSystem files must be separated,absenceAt the same time1Partition.

BIOS+MBR1Once the system is installedafterIf the system boot file is in a separate partition, this partition can be visible in the operating system or set to hidden, and the system can start normally; In the operating system, the ESP partition where the UEFI+GPT system boot file is located isabsenceVisible, automatically hidden after entering the system.

------------------------ThisIt is a traditional Legacy operation process:

This is the UEFI running process:

Compared to using traditional BIOS boot methods, UEFI BIOS reduces the steps of BIOS self check, saves time, and accelerates platform startup. If you are interested, please continue to read on. BIOS and UEFI, MBR, and GPT configurations:.

(1) BIOS+MBR: Available, bootable system is the most common! This is the most traditional, and the system will support it; only1The downside is thatabsenceSupport hard disk with capacity greater than 2T (2) BIOS+GPT: available, but unable to start the system BIOS, you can use the hard disk of GPT Partition table as the data disk, butabsenceAble to guide the system; If the computer has a hard disk with a capacity of less than 2T and a hard disk with a capacity of more than 2T at the same time, the MBR Partition table can be used to install the system for those with a capacity of less than 2TGPT can be used for 2T.

There is no problem with the Partition table to store data, but it is also a reasonable mode for the system to use 64 bit system BIOS+GPT. However, in this mode, the system on this hard disk cannot be started. If it is only used as a storage disk, it will not affect the primary hard disk BIOS+MBR installation system, and the secondary hard disk BIOS+GPT storage files, which are many.

The mode used by audiovisual file enthusiasts (3) UEFI+MBR: UEFI can be set to Legacy mode (traditional mode) and CSM compatible module can be opened to support traditional MBR startup, but it is purely a waste of time and the effect is meaningless like BIOS+MBR (4) UEFI+GPT: available and can boot the system.

Most common! If the future trend is to use a hard drive larger than 2T as a system disk to install the system, this is necessary, and the system must use a 64 bit system, otherwise it cannot be installedBoot but the system isabsenceIt can be directly used after installation under PE, and boot needs to be processed before UEFI and GPT complement each other.
