Hard disk includes solid state hard disk (SSD disk, new hard disk), mechanical hard disk (HDD traditional hard disk) and hybrid hard disk (HHD, new hard disk based on traditional mechanical hard disk). SSD uses flash memory particles for storage, and HDD uses disks for storage. HHD: Hybrid hard disk (HHD) is a kind of hard disk that integrates magnetic hard disk and flash memory. Most hard disks are fixed hard disks, which are permanently sealed and fixed in hard disk drives.
Set the first startup item when entering the bios.
The first boot device sets the hard disk to boot for the first time.
The second boot device sets the hard disk as the second boot.
Booting the device for the third time is to set the hard disk to boot for the third time.
Select the hard disk in the first boot device, and the hard disk is the first boot.
HDD-0, HDD- 1 and HDD-2 are all relatively old motherboards.
The number behind the hard disk indicates which hard disk it is. A * * * can connect four hard disks, starting from 0 and ending at 3. They are: HDD-0, HDD- 1, HDD-2 and HDD-3.
The general setting method is in the advanced bios function (the older motherboard is in the BIOS function setting), and then select the first boot device (there is also a motherboard called boot sequence) and set it as a CD.
If you want to start using USB, you can choose USB-HDD or USB-ZIP (depending on the type of USB startup disk), and now the startup sequence of the motherboard is similar. Selecting the first boot device will pop up a device selection box with several options (as shown below). You can choose universal USB-HDD (depending on the type of USB startup disk). Of course, your USB flash drive must be a PE boot disk or a DOS boot disk or a boot disk with other boot programs.
