How can I enter a pure DOS state without an optical drive? 20

If you are a Win9X system (such as Win98), press F8 when starting, and select the last item to enter DOS

If you are a system, you need to make a DOS boot floppy disk under the system, and then you can boot into DOS

Ghost has an extraction tool under 2000, you can extract all the files from the gho to the specified location, you can also extract any file to the specified location, if you can access the Internet, try the next one!

Find a floppy disk to make a ghost image, and you're good to go!

Do you have an email address? I have a DOS program here that I can send to you, regardless of the system.

In the Windows 98 Control Panel, under the Add and Remove Programs option, select Make Startup Disk, and start the computer with the floppy disk.

You can also use a floppy disk to boot up, and you can use a DOS boot disk to boot up.

Press F8 when the black screen is activated

Make a bootable floppy disk, format a: s q

DOS is a very old, but powerful thing, and it is estimated that not many people can use it proficiently now, including launching Ghost under DOS.

The landlord said DOS installation,It should refer to the ghost method.,Ghost is indeed running under pure DOS.,But now there's PE.,It's much easier to start GHOST.。

1. It doesn't matter if you don't have an optical drive, you can use a USB flash drive or mobile hard disk to boot PE to install the operating system. (It is the most common way to install the system at present, and the speed is much faster than the optical drive.) )

2. If the system can still start normally, you can also copy the contents of the installation disk to the hard disk to install the system.

3. If there is no optical drive, the motherboard of the machine does not support USB flash drive boot, and the system on the hard disk cannot be booted now. It doesn't matter either, you can remove the hard drive and take the opportunity to rejuvenate the system to install it. (Take the opportunity to resurrect:.)

It is to remove the hard disk,Hang it on other computers,When the ghost completes the restart,Force shutdown,Then install the hard disk back on the original machine,Boot will automatically enter the system installation process。 ）

In short, as long as the hardware is good, you can install the system. There are many ways.

The system could not find the optical drive.

In this case, the indicator light of the optical drive flashes, and the entry and exit compartment and spindle motor are also running normally, but after starting the computer and entering the Windows system, there is no drive letter for the optical drive in "My Computer", and the existence of the optical drive cannot be detected by selecting "Control Panel" to add new hardware, or restarting.

To solve this problem of "optical drive loss", you need to start from two aspects: "hard" and "soft".

1. Hardware check: First of all, check whether the data cable connected to the optical drive is plugged in firmly or reversed, and whether there is any open circuit, poor contact, etc. If necessary, this can be verified with a normal cable replacement.

If the optical drive and the hard disk are connected to the same IDE interface using the same data cable, you also need to check whether the master and slave jumper settings of the optical drive are correct.

2 Software problems: After confirming that the hardware connection is correct, you can use the following two methods to try to solve it:

Configure and. Normally, these profiles will not be used when the drive is functional. This is because using the Optical Drive Real Mode drivers in these profiles will reduce the read performance of the optical drive.

And after the optical drive is "lost", we can add the real mode driver of the optical drive to these configuration files, and the optical drive can be found after restarting. Then delete the two configuration files and reboot, and the system will automatically use the standard drivers under Windows to drive the optical drive.

Remove the hard disk controller. When most people find that they have "lost" their optical drive, they first think of using Windows' "Find New Hardware" feature to find the optical drive. However, the "Find New Hardware" feature doesn't always work, and it often fails to find the "lost" optical drive.

The solution to the problem is to open "My Computer" "Control Panel" "System" "Device Manager" "Hard Disk Controller" and click "Delete" and the computer will ask to restart. After restarting, the computer will find the primary IDE controller and the secondary IDE controller and automatically install the drivers, and the "missing" optical drive will be found when the computer is turned on again.
