Disk partition format and boot relationship:
There are currently two main types of disk storage data structures:
MBR partition and GPT partition. GPT partition is relatively new and better than MBR.
When the computer is turned on, it needs to be booted by the BIOS. The booting methods of the two data structures are different, so there are two boot modes:
Legacy boot mode: disk partitioned in MBR format
UEFI boot mode: disk partitioned in GPT format
Some old motherboards and computers do not support UEFI boot mode, so you can only start with Legacy boot mode, and you need to use MBR format when partitioning the disk.
In the BIOS interface, there will be two U disks for a system, one of which starts with UEFI, which is used for UEFI boot mode, and the other without which is used for Legacy boot mode. If there is no U disk with UEFI beginning displayed, only a U disk without UEFI beginning is displayed, indicating that only Legacy boot mode is supported.
It is recommended to use UEFI boot mode and GPT format partition disk
Use the command prompt to switch the data storage structure of the disk.
Press shift+F10 to open the command prompt.
Enter Diskpart and
press Enter. Enter list and space disk and press Enter to list all the disks in the computer.
Enter select and space disk and press Enter to select the operation. Disk
Enter clean and press Enter to clear all partitions on the disk.
Enter convert space GPT to switch GPT format or enter convert space MBR to switch MBR format
The formatting format of the U disk
is FAT32: a single partition cannot exceed 32G, and a single file cannot exceed 4G
exFAT, NTFS: Some old motherboards and computers cannot recognize
