Error when attempting to boot Centos 7 install from pen drive affects users who are trying to install CentOS 7 using a USB drive as their installation medium. This error is frustrating because it prevents users from completing the installation process, which can lead to delays in getting the system up and running.
The issue of not being able to boot from a USB drive can be caused by various factors, including the type of device used, the file system on the device, or issues with the installation process itself. In this case, we will focus on troubleshooting common reasons for this error and provide steps to resolve it.
🔍 Why This Happens
- The primary reason for this error is that the dd command is not properly formatted or executed. The dd command is used to copy data from one location to another, but in this case, it's being used to write an ISO file to a USB drive without specifying the correct format options. This can lead to issues with the file system on the device and prevent the installation process from completing successfully.
- Another possible reason for this error is that the USB device is not properly recognized by the computer. This could be due to issues with the USB adapter or the memory card, or it could be a problem with the FreeDOS operating system itself.
🛠️ Step-by-Step Verified Fixes
Formatting and verifying the USB drive
- Step 1: Insert the 8Gb memory card into the USB adapter and ensure that it is properly connected to the computer. Then, use the dd command again, but this time specify the correct format options, such as `-f` for forcing the overwrite of the existing file system, like so: `dd if=CentOS-7-x86_64-DVD-1611.iso bs=4M of=/dev/sdb`. This will ensure that the USB drive is properly formatted and recognized by the computer.
- Step 2: After formatting the USB drive, use the `fat32` command to verify its file system: `fat32 /dev/sdb`. If the file system is not recognized, you may need to reformat it using the `mkfs.ext4` command. This will ensure that the USB drive is in a format that can be used for installation.
- Step 3: Once the USB drive has been properly formatted and verified, insert it into the computer's boot device (such as a USB port) and attempt to boot from it again. The installation process should now complete successfully.
Reinstalling FreeDOS
- Step 1: If the issue persists after formatting and verifying the USB drive, you may need to reinstall FreeDOS on your computer. This will involve creating a new partition table, installing the FreeDOS operating system, and configuring it as the primary boot device.
- Step 2: To reinstall FreeDOS, use the `fdisk` command to create a new partition table: `fdisk /dev/sda`. Then, select the partition you want to install FreeDOS on and follow the prompts to complete the installation. Once FreeDOS is installed, you can insert the USB drive into the computer's boot device and attempt to boot from it again.
