Why can t I read butterflies when I turn on the system and install it?

It's usually in the second item, and you can find it by looking for it slowly.

This is usually done in the BIOS Features Setup

boot sequence.

Press delete after powering it on

Enter the BIOS interface.

It's good to set it to an optical drive to boot inside.

Some drivers can't read some discs.

There are also some drivers who can't read the system disk because they look at some CDs.

It is strongly recommended not to use the drive to watch the disc, there is a lot of damage to coarse potatoes!

Hello, I've got back.

I told you that, why don't you believe it?

A driver can't achieve VCD,*** The same effect can be released on any disk,Even VCD he can't guarantee that every disc can be read,Not to mention that driving it is just a simple composition of the dust。

Not every disc can be read, like a rough one, a substandard one, or a higher level than the driver, with decoding. Many, much more.

In short, if your driver can put out anything, then ......The manufacturer of this drive has long been the richest man in the world.

You need to set the computer to optical startup, which means that the computer will read the optical drive first when it starts up, so that if there is a disc with optical start in the optical drive, it can be read before the hard disk starts up (such as when installing the system from the optical disk).

How to set it up:1Start the computer and hold down the DEL key until the BIOS settings window appears (usually with a blue background and yellow English text);

2.Select and go to the second item, "BIOS Setup". Find the item or group that contains the word boot, and find the three items in order: "first", "secend", and "third", which represent "first start", "second startup", and "third startup" respectively.

Here we set Frist to the "CDROM" (CDROM) (the second and third are set to the hard disk to start floppy;

3.After selecting the startup mode, press the F10 key, the E dialog box appears, press the "Y" key, and press Enter, the computer will automatically restart, proving that the changed settings have taken effect.

Then turn it on, put the disc back into the optical drive, and you can reinstall your computer without any problems.

I have a system installation in my space**I hope it solves your problem.

The reasons for this are:

First of all, the optical drive may be a problem with the life span, and if the normal optical drive is used frequently, it will be out of condition in less than two years.

Thirdly, when the optical drive is used for a long time, the laser head will fall dust, affecting reading and writing.

The following methods can be employed:1Buy a disc drive cleaning platter and clean it, it may recover.

2.Turn on the optical drive and use the computer to clean the soft cloth of the screen, dip the cleaning solution and wipe the laser head several times.

3.Find a disc and try it again, it may be a disc drive.

4.Remove the optical drive in the Device Manager and try reinstalling it.

5.If none of the above methods work, then the optical drive is hopeless. You'd better get a new one.
