The installation system always goes wrong, and what should I do if I have several systems like this?

Old machine, right? Block the floppy drive from the BIOS settings.

The following is copied over:

Press the "Delete" key on startup to enter the BIOS:

1.Turn off the floppy drive.

standard cmos → drive a：none

2.Tell Windows 9X, ME no floppy drive.

advanced bios features →report no fdd for win 95：yes

3.Disable the floppy disk controller.

integrated peripherals→ onboard fdc controller：disabled

Tips: Among them, the first two items are required, as for the floppy disk controller, because there is no floppy drive, there is no need to open it. Even if you have a floppy drive, it is recommended to set "Report No FDD for Win 95" to Yes?

Note: Due to the large number of BIOS versions, the above options may be slightly different from what you actually see in your motherboard BIOS, but you can achieve this by turning off the "Floppy Drive A" and "Floppy Drive Seek" options.

The best thing to do is to replace it with a new one.

Reload. Delete the 300m partition in front of the system partition.

The boot mode selected is incorrect, the U disk is selected for the U disk, and the optical drive is selected for the optical drive.

If you can't fix it, you have to reinstall the system, which is the most fundamental solution. If the system can't get in, with the help of someone else's computer, use a USB flash drive to install the system, the general process is as follows:

3. Find and select the one-click system program on the desktop, and follow the steps;

4. Wait for the installation and restart the computer;

5. After restarting, wait for the system to be configured after normal boot, and try again if you can't enter the system if you can't get into the system if you don't boot normally;

6. If you still can't get in, you have to consider whether it is an image file and change the image.

Fix it first, try it, if it doesn't work, you can only reinstall the system.

It shouldn't work, the system needs to be repaired.

In this case, the system can only be reinstalled.
