What should I do if the U disk cannot be found during centos7 installation?

Set the startup items, boot to the installation interface, and select the required options according to the direction (generally choose the first item)

After selecting the first item, press the Tab key on the keyboard to edit (in previous versions, press the E key to enter the editing interface).

Here comes the key point:

Change vmlinuz initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 quiet

to vmlinuz initrd=initrd. img inst.stage2=hd:LABEL=U disk name quiet

Then press Esc to exit editing and perform installation or Ctrl x to perform installation (different versions are slightly different).

Tell me a few more words:

There are usually two ways to deal with this in other tutorials (neither recommended by the author):

1. Install directly until an error occurs. Use the command line to check the U disk number/drive letter, restart the installation and then specify the drive letter (difficult to operate, extremely not recommended)

2. Change vmlinuz initrd=initrd.img inst.stage2=hd:LABEL= CentOS\x207\x20x86_64 quiet

                                                                                                                                                                                                                                            Changes sdaX (where sdaX quiet and then perform the installation operation. (The process is cumbersome and not recommended)

The installation begins, followed by the familiar language selection interface.

Then set it according to your needs. All items with yellow exclamation marks must be set before you can click Next. Software selection and installation location are the two most important items that must be set up. Generally, it is better to choose gnome desktop when learning to use it.

Generally, the installation source does not need to be set. It will usually be set automatically after the software selection is completed. If the installation source still has an exclamation mark after the software selection is completed, If it exists, it basically means that there is a problem with downloading the image file and you need to re-download and create a boot disk (a small probability event). After configuring other installation options step by step, you can start the system installation normally.

#You can create a new user and set a root password during the installation process, or you can create it after the installation is complete. During the root password setting process, you usually need to set a password with a certain complexity. A password that is too simple will usually prompt you, but if you insist on setting a simple password, you can just continue to click OK to set it successfully.

Notes

Note: The U disk name does not support Chinese. To reduce unnecessary trouble, do not use spaces in the name. This name can be used in the image Make changes after writing to USB flash drive.

The installation process of different versions of images is slightly different. You can try Ctrl x to start the installation or Esc to exit the editing interface and press Enter to install.
