How to start the boot strategy after the system crashes (1)

        The system crashes, can't start normally, need to reinstall the operating system, but the computer always starts from the hard disk by default, then how do we boot the system? Oh, don't worry, you will know right away. 1. Ordinary built-in optical drive boot system Generally, when users use the computer, they usually need to put the boot item in the “HDD-0” option to boot the computer at the fastest speed. However, once the system crashes, the CD-ROM boot system is required. How should I set it up? The first step is to enter the BIOS setup interface. Start the computer and press the “DEL” button to enter the BIOS interface of the motherboard. The second step is to set the basic step selection “Advanced BIOS Features” and select “Boot Sequence” in the “Advanced BIOS Features” page. Figure 1 Press “ Car & rdquo; button, enter the "Boot Sequence" interface, there is "1st/2nd /3rd Boot Device" option, (first /second /third boot device), this allows you to set the BIOS to load operation The order of the system boot devices, select “1st Boot Device", such as: Figure 2 has the following settings: Floppy system first tries to boot from the floppy disk drive. The LS120 system first attempts to boot from the LS120. The HDD-0 system first attempts to boot from the first hard drive. The SCSI system first attempts to boot from SCSI. The CDROM system first attempts to boot from the CD-ROM drive. The HDD-1 system first attempts to boot from the second hard disk. The HDD-2 system first attempts to boot from the third hard drive. The HDD-3 system first attempts to boot from the fourth hard drive. The ZIP system first tries to boot from the ATAPI ZIP. The LAN system first tries to boot from the network. Select “CDROM”, use the CD-ROM to install the system, press ESC to return to the BIOS main menu, select “SAVE & EXIT SETUP" to save and exit the BIOS setup environment, put the system boot CD, restart the computer, The CD boot system can be implemented. Tip: Depending on the boot device installed on your computer, the optional devices that appear in the “1st/2nd/3rd Boot Device” option are different. For example, if your system does not have a floppy drive installed, the “Floppy” setting will not appear in the boot order menu.

2. USB device boot system Currently, USB devices are widely used and can support more devices, especially laptops. Many laptop manufacturers now have a built-in optical drive in order to save costs or reduce the weight of the machine. Therefore, many of the friends have equipped the laptop with an external optical drive. The most common external optical drive, connected to the notebook through the USB interface, can the computer be started after the system crashes? The answer is certainly yes. The first step, determine the device First of all, to determine whether the computer supports USB device boot, if it is not supported then can not be used, we can check the motherboard BIOS to know whether this option is supported. Under normal circumstances, the original optical drive can basically boot and identify the optical drive. For example, IBM's original USB optical drive can successfully boot and identify the optical drive on the S and X series. The second step, the basic setup step into the motherboard BIOS interface of the laptop, select the "Boot" option, find the option to select the boot sequence to mediate, there is an option for "USB CDROM", selected “Save exit”. Connect the USB drive to your notebook and insert the boot CD into your CD-ROM drive. Restart the computer and boot the system with an external USB drive. There are other USB device options in the Tips: “USB CDROM” options, such as USB ZIP, USB FDD, USB HDD, etc., which are selected for use with different devices. 3. Using other interface startup methods Most laptops now use USB external optical drives. Of course, there are other interface types, such as 1394 and PCMCIA cards. Let's focus on the use of these two interfaces. Startup method. First look at the 1394 interface, now there are more machines using 1394 external optical drive, such as SONY VX89, SRX99 and so on. The first step, check the interface This step is the same as USB, we must first check the computer to see if its BIOS boot settings support 1394 interface type. The second step, making a 1394 boot disk 1394 CD-ROM drive also needs to load a special boot image before you can use Nero boot disk burning tool to create a 1394 boot CD. However, it should be noted that if you are making multiple continuous system recovery discs, you need to add this boot image to each disc, otherwise it will not recognize the disc after the disc change. The third step, set up This step is exactly the same as previously introduced, enter the motherboard BIOS, start the selection, select the relevant options in 1394, then save and exit, and then restart. Finally, let's talk about the PCMCIA card. The PCMCIA card drive is also an ideal choice for users. Like the 1394 optical drive, it must load a dedicated boot image. You can boot the PCMCIA optical drive using a bootable USB floppy or a CD loaded with the boot image. This way you can use it normally. The above-mentioned methods are all some of the system startup methods that users often come into contact with. Of course, the startup mode of the notebook computer is somewhat special. If the notebook is equipped with a built-in optical drive, the startup mode is the same as that of the ordinary desktop computer. The same. Then there are some special devices, such as network boot, floppy disk drive, etc. These are the startup methods we rarely use now, and we will have the opportunity to continue to discuss with you in the future.
