System guidance methods without worrying about system crashes

The system crashes and cannot be started normally. You need to reinstall the operating system, but the computer always starts from the hard disk by default. How can we boot the system? Well, don't worry. You'll know right away.

1. General built-in optical Drive boot System

General users in the usual use of the computer, generally want to boot items in the "HDD-0" option, so as to guide the computer as quickly as possible, but, once the system crashes, you need to drive the system, how should I set it?

Step 1: Go to the BIOS settings page

Start the computer and press "DEL" to enter the BIOS page of the motherboard.

Step 2: set the basic step

Select "Advanced BIOS Features" and select "Boot Sequence" on the "Advanced BIOS Features" page, as shown in figure 1.

 

Figure 1 guiding order

Press the "enter" key to go to the "Boot Sequence" interface, which has the "1st/2nd/3rd Boot Device" option (first/second/Third start Device ), this option allows you to set the sequence of Boot devices that the BIOS wants to load into the operating system. Select "1st Boot Device", as shown in figure 2.

The following settings are available:

The Floppy system first tries to boot from the Floppy drive.

The LS120 system first tries to boot from LS120.

The HDD-0 system first tries to boot from the first hard disk.

The SCSI system first tries to boot from SCSI.

The CDROM system first tries to boot from the CD-ROM drive.

The HDD-1 system first tries to boot from the second hard disk.

The HDD-2 system first tries to boot from the third hard disk.

The HDD-3 system first tries to boot from the fourth hard disk.

The ZIP system first tries to boot from the atapi zip.

The LAN system first tries to boot from the network.

Select "CDROM" and use the optical drive for system installation. Press ESC to return to the main menu of BIOS, select "SAVE & exit setup", SAVE and EXIT the BIOS setting environment, and put it on the system boot disc, restart the computer to boot the system.

TIPS: depending on the Boot Device installed on the computer, the available devices in the "1st/2nd/3rd Boot Device" option are different. For example, if your system does not have a soft drive installed, the "Floppy" setting will not appear in the Start sequence menu. 2. USB device boot System

At present, USB devices are widely used and many devices are supported, especially laptops. Many laptop manufacturers do not have built-in optical drives to save costs or reduce the weight of their computers. Therefore, many of them have equipped their laptops with an External Optical Drive. The most common External Optical Drive is connected to the laptop through the USB interface. Can the computer be started after the system crashes? Of course, the answer is yes.

Step 1. Determine the device

First, determine whether the computer supports USB boot. If not, the computer cannot be used. We can check whether the motherboard BIOS supports this option. In general, the original optical drive can boot and recognize the optical drive. For example, the original USB optical drive of IBM can boot and recognize the optical drive in S and X Series.

Step 2: Basic settings

Enter the BIOS interface of the motherboard of the laptop, select the "Boot" option, and find the option to select the Boot sequence for mediation. One option is about the "usb cdrom" option, click "Save and exit ". Connect the USB drive to the notebook and put the boot disc into the optical drive. Restart the computer to boot the system through an external USB drive.

Tips:

The "usb cdrom" option also contains other USB device options, such as usb zip, usb fdd, and usb hdd, which are used with different devices.

3. Use other interface startup Methods

At present, most laptops use USB External Optical drives. Of course, there are also other interface types, such as interfaces such as 1394 and PCMCIA cards, next, let's take a look at the startup methods using these two interfaces.

First, let's take a look at the 1394 Interface. Now there are many machines using 1394 External Optical Drive, such as SONY's VX89 and SRX99.

Step 1. Check the interface

This step is the same as USB. We must first check the computer to see if its BIOS boot settings support the 1394 Interface Type.

Step 2: Create the 1394 boot disk

1394 when the optical drive is started, a special boot image must be loaded before you can use the Nero Boot Disk Burning tool to create the 1394 boot disc. However, if you create multiple consecutive system recovery discs, you must add the boot image to each disc. Otherwise, the disk will not be recognized after the disk is changed.

Step 3: Set

This step is exactly the same as previously described. Go to the motherboard BIOS, start the selection item, select the 1394 option in it, save and exit, and then restart.

Finally, let's talk about the PCMCIA card. The PCMCIA card optical drive is also an ideal choice for users. Similar to the 1394 optical drive, a dedicated boot image must be loaded. You can use a portable USB drive or a boot image disc to boot the PCMCIA Optical Drive. In this way, you can use it normally.

The methods we introduced above are some of the system boot methods that users often come into contact with. Of course, the startup methods for laptops are somewhat special, if a notebook with a built-in optical drive is started in the same way as a Common Desktop. There are some special devices, such as network startup and floppy drive startup, which are rarely used. We will continue to discuss with you later.
