2. Solve the problem of not finding the CD during the installation process

## After choosing to continue, it prompts that the installation failed in this step , let us remount the CD-ROM before continuing.

1. But there is really no CD-ROM drive on the server. What should I do? Are there many students who feel bad when they encounter this mistake? Today, let’s talk about how to solve this error. Do you immediately feel that there is hope in life, haha!

After selecting Continue on the above interface, the following interface will appear. At this time, if you choose to run shell, you will enter a shell interface.

You will encounter many problems when installing ubuntu server using a USB disk If there is trouble, such as the cdrom cannot be mounted or the mounting program has an error, then I will start with my first step:

1), burn the ubuntu server image ISO to a USB flash drive, and then copy the ISO image file again to the USB drive.

2). When inserting the USB disk into the computer and restarting the computer, when selecting the boot device, the program detects an error from booting from the USB disk to the cdrom. Generally, the error occurs in 13% of cases. The following is the solution.

3). Enter the shell and use ls /dev/sd* to see what devices are there. The general situation is like this

/dev/sda /dev/sda1 /dev/sda3 /dev/sda5 /dev/sdb /dev/sdb1

Then unplug the USB flash drive and use ls /dev/sd*. You will find that only /dev/sda /dev/sda1 /dev/sda3 /dev/sda5 can be seen. It is dev/sdb, then the partition on the USB disk is dev/sdb1. Create an empty directory under the root, command mkdir uinstall and then mount the USB disk to this directory.

mount /dev/sdb1 /uinstall

4), and then mount the iso image command of the ubuntu server in the USB disk:

mount -o loop -t iso9660 /uinstall/ubuntu-12.04.5-server-i386. iso /cdrom

ls /cdrom

5), and finally exit. After exiting, you can install normally.

3. Re-detect and mount the CD, and then continue all the way. Usually the subsequent process should be smooth.

It is said that this is normal. If you are unlucky, you will encounter the second problem below.
