I want to reinstall the system, but after changing the disc to boot up, I still enter the VISTA 100

Turn off the high-speed function of the hard disk, there is a jumper on the back of the hard disk, if it is unplugged, it is to tell the status, if it is plugged in a specific position, it is the normal speed. For details, you need to look at the instructions on the hard drive, which is marked after each hard drive. The jumper is a little bit of a mess, and I can't describe it.

Yes, my windows7 is the same, it automatically skips the optical drive detection, and it can't be started even if there is an installation disk!

So, I used a stupid approach!

Install a Ghost Toolbox or DOC Toolbox and prepare an XP image!

After restarting, F8 enters Select Start, Select Toolbox, and Restore XP Image!

Of course, it is possible to restore it halfway through and shut it down, so that the optical drive should be able to recognize the boot, just in case, I still installed the XP system).

And then what. Wouldn't everything be easy?

There is a jumper behind the optical drive (on the left side of the power supply), change it to the main device (the first, the default is the second), the hard disk also has, change to the second, the optical drive driver is installed, and it is changed back, I can do this, if you can also divide it to me.

Press ESC or F12 when booting up, select the startup item, and boot from the optical drive.

Always press ESC when you first turn it on, and choose the optical drive when you come out with the options.

The first boot device needs to be a CD-ROM drive, and when there is a paragraph in English, press any key to boot from cd-rom

Any key (e.g. space) must be pressed.

Set the CD-ROM to the first one in the BIOS, and then notice that the screen will let you press a key to enter the CD-ROM when you start the computer, and if you don't press it, you will go directly to the original operating system, as if it is F8,

Some boot discs, people also boot from the optical drive, people tell you "press any key from cd..."That is, press any key to boot from the disc, and if you don't press it, it will boot from the hard drive.

Press enter once when the light driver is displayed.

Is the BIOS mistuned? Press F12 while booting up and try again! That's how I put it on!

Go to the disc again, select the disc PE item to boot, after entering the PE, find (as it should be) on the desktop to boot the repair, and select Auto repair.

Power on press F12Select CD or ***OK and the disc boot directory will appear.

You didn't set the light enlightenment:

The so-called optical start means that the computer reads the optical drive first when it starts up, so that if there is a disc with optical start function in the optical drive, it can be read before the hard disk starts (such as when installing the system from the optical disc).

How to set it up:1Start your computer and hold down the Del key until the BIOS setup 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 can set it to "optical drive", "floppy drive" and "hard disk" in order. (If you don't see these three e-articles on this page, usually the option menu on the right side of boot is "setup", then press enter to see it).

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

The XP system has turned off the automatic start function of the optical drive, and it needs to be operated.

The upstairs looked, the head was big.

Match with a USB stick.

If you say it's going to crash, then it might be a hardware problem, and I recommend going to the pit !!

Press the del key first to come out of the bois settings, and then find the first boot (as if it were a first....I forgot) and then set to select CD-ROM,F10Save exit,Restart the computer and the contents of the disc will come out。
