The computer can t enter the system when it is turned on, and it shows BOOT FROM CD

Press the DEL key to enter the BIOS to see if the hard disk is not detected, and whether the parameters of the hard disk are set correctly, if you don't know how to set it, choose to restore factory settings to save, or the hard disk may not be powered on, check the hard disk connection, meaning:"If the hard disk fails to boot, please insert the system disk or press the enter key"If the problem is not solved, then set it in the BIOS settings to boot from the optical drive, reinstall the system, and the fault persists, that is, there is a problem with your hard drive.

If there is a problem with the data cable, you can use the alternate method, that is, take your hard disk to someone else's computer for testing, if the hard disk is fine, just change a data cable, your optical drive is good, let the system detect it, you can change the data cable of the optical drive to the hard disk, this is not to worry, because the optical drive and the hard disk are the same IDE equipment.

That solves the problem.

It doesn't matter which one to start from,The important thing is to check whether there is a disc in the optical drive first,And then there is a reason why you can't save the BIOS settingsIn addition to the CMOS battery has no power,Haier computer also has a one-click memory recovery function,After modifying the BIOS, you have to F10Save it first,You can。

Check whether there is a disc in the optical drive, generally except when installing the system, it is better to set the hard disk as the first startup item at other times.

The BIOS is only set up to boot the optical drive.。。。 Boot up and press del or f2 to enter the BIOS and change the first boot item to hard disk. hdd

Sometimes, pressing any key is just booting from the optical drive. If it can't be saved, it may be that the BIOS battery is dead, try a different battery.

This prompt should mean this: The disk boot failed, please insert the system disk and press enter.

Can you press Ctrl+Alt+Del to enter the system first?

Either the MBR is lost, or the boot file is lost.

There is a problem with the system or hard drive.

Make a system first, and basically solve the problem.

If the system is useless, you have to test the hard disk.

It should be set to boot the boot from cd as the first boot item, and the first boot item can be set to the hard disk boot in the BIOS. Here's how:

1.Restart your computer on the boot screen.

2.Keep tapping F2 while booting up until you enter Bootmenu3Go to the bootmenu menu.

4.In the Bootmenu menu, select Advanced BIOS Features

5.On the entry screen, select Hard Disk Boot Priority6After entering, you can display the HDD in front of the general hard disk according to the display prompts, and move the hard disk boot to the first place.

1. Press the power button, click (meaning stop): delete button (different brands of computers and motherboards, the entry BIOS button is different), and enter BIOS.

2. Use the arrow keys on your keyboard to move to the second item: Advanced BIOS Functions, Input.

3. In the window that opens, use the arrow keys to move to: first boot device, enter.

4. In the first boot device window that pops up, use the arrow keys to move to: cdroh and press enter.

5. Go back to the "Advanced BIOS Features" window and press the F10 key on your keyboard.

6. The little red window that pops up: saue to CMOS and exit(y n)? Type "Y" (save the CMOS settings and exit) and press Enter (Enter).

7. The computer automatically restarts, enters the boot screen, and then enters the system.

It means that you boot from the optical drive, but there is no disc in the optical drive, and you can solve the problem by setting the hard disk to the first boot.

Tool: Computer.

1. Press the power button, tap (that is, press and stop), delete button (different brands of computers and motherboards, the entry BIOS button is different), and enter BIOS.

2. Use the arrow keys on your keyboard to move to the second item [Advanced BIOS Features] and press Enter.

3. Use the arrow keys to move to [First Boot Device], and then click Enter.

4. In the pop-up First Boot Device window, move the arrow key to [cdroh] and press enter.

5. Go back to the Advanced BIOS Features window and press the F10 key on your keyboard.

6. In the pop-up red window [saue to CMOS and exit (y n)? ] (save the CMOS settings and exit) and press Enter.

7. Wait for the computer to restart before you can enter the system.

Power on to enter. Motherboard settings. Go to boot

Option to change the 1st CD to H.d..That's it.

Press the DELETE or F2 or F12 button on boot (the key presets are different for different brands of computers, but pay attention to the prompt at the bottom of the screen when you turn on the computer), enter the BIOS to find the root boot item, and set it to the hard disk to boot.

boot from cd, means that the system boots from cd, is it that you forgot to take out the cd disk from the optical drive after installing the system, if not, please enter the BIOS settings when booting, change the CD boot to boot from the hard disk (hard disk-hard-disk), save and restart after exiting.

This is a problem with your BIOS settings, you press del when you turn on the computer (the general computer is to press this key, there are also special, anyway, it will prompt what press * to setup when booting up, you just press that key), and then you can go into the motherboard settings, choose the second one (the one that starts with adva), there are first boot dreves in it, second boot dreves and the like, change any one to hard disk should be fine.

Analysis: Startup disk not found. Failed to boot from optical drive. If the CMOS boot items have not been modified before, it is likely that the hard disk has not detected them.

Processing: 1. Turn off the power and open the chassis, replug and unplug the power and data cables of the hard disk, turn on the computer again, press the del key (F2 or other for the notebook) to enter the CMOS, and see if the hard disk can be detected. If the available system USB flash drive is detected, use diskgen to detect and repair it after it is booted.

If not, replace the cable or hard drive and reinstall the system.

2. Turn on the computer, press the DEL key (F2 or other for notebooks) to enter CMOS, and set the hard disk as the first boot item. Press F10 to save y to confirm the exit restart.

Make sure there is no disk in the drive when booting, or press delete to enter the advanced BIOS features when booting up (different models may be different anyway, it is the option with BIOS), and then turn boot 1 or boot first anyway, the first one to change its CD-ROM to hard disk, then press F10 and press Y enter, reboot and it's done.

Suggestion: Get a system disk boot repair, like some Tomato Garden XP disks, there is a system repair or boot repair in it, which version, I don't remember. If the system is vista or win7, it comes with the system to repair.

Put it on the system disk and repair it. Exit, change the BIOS settings, and change the boot item Hard Disk to the first boot, as mentioned above.

disk boot failure, insert system disk and press enter The prompt is: The disk boot failed, please insert the system disk and press the enter key. But if you can press it again"Ctrl+Alt+Del to enter the system", you can give it a try, restore the BIOS default, and then check the system files to see if it is caused by installing multiple systems.

Then there is a hardware failure of your computer, but from your operation, this possibility is very small and can be used"Source of efficiency"Take a look at such hard drive detection software.

One reason is that you set up boot from a disc and a non-booting disc is placed in the disc and the other problem is that something is wrong with your hard drive.

If you don't have a disc in your drive, or if the settings in your BIOS are messed up, you might as well consult your computer repairman, and if it doesn't work, take down your CD-ROM drive.

The hard drive cannot be found, it may be that the hard drive cable is loose, or the boot in the BIOS has been changed.

Enter the BIOS interface on the boot interface, and set it up for First Boot.
