How do I erase everything on Ubuntu?

If you want to completely erase everything on your Ubuntu system and start from scratch, there are a few ways to do it. One way is to reinstall Ubuntu from scratch, which will overwrite everything on your system with a fresh copy of the operating system.

Another way is to use a tool like “GParted” to delete all of the partitions on your system, which will effectively erase everything.

Or, you can use a live CD/DVD/USB of Ubuntu and choose the “Erase Disk and Install Ubuntu” option when prompted during the installation process. This will also erase everything on your system and install a fresh copy of Ubuntu.

Whichever method you choose, make sure you have a backup of any important data on your system before proceeding, as all data will be lost when you erase everything.


3 Ways To Securely Erase A Hard Drive On Linux

Do you have sensitive data on your Linux hard drive that you want to make sure is gone for good? If so, then you’ll need to securely erase the drive.

There are a few different ways to do this, and the best method will depend on what you’re trying to achieve. If you just want to make sure that the data is unrecoverable, then you can use a regular file shredder. However, if you want to make sure that the drive is completely wiped and can’t be used again, then you’ll need to use a disk eraser.

Let’s take a look at three different ways to securely erase a hard drive on Linux.

1. Use a File Shredder

If you just want to make sure that the data on the drive is unrecoverable, then you can use a file shredder. This will overwrite the data on the drive with random data, making it impossible to recover the original information.

There are a few different file shredders available, but one of the best is GNU shred. To install it, just open up a terminal and type in the following command:

sudo apt install shred

Once it’s installed, you can use it by running the shred command with the path to the file or folder that you want to shred. For example, if you want to shred the file “example.txt”, you would run the following command:

shred example.txt

This will overwrite the data in the file with random data. You can also use the “-u” flag to shred every file in a directory, like this:

shred -u /path/to/directory

2. Use a Disk Eraser

If you want to make sure that the hard drive is completely wiped and can’t be used again, then you’ll need to use a disk eraser. This will erase all of the data on the drive, including the partition table and boot sector. As a result, the drive will be unusable and will need to be reformatted before it can be used again.

There are a few different disk erasers available, but one of the best is Darik’s Boot and Nuke (DBAN). You can download it from here.

Once you’ve downloaded it, you’ll need to burn it to a blank CD or USB drive. To do this, you can use the “dd” command. For example, if you’re using a CD, you would run the following command:

sudo dd if=dban-2.3.0_i386.iso of=/dev/cdrom

If you’re using a USB drive, you would run the following command instead:

sudo dd if=dban-2.3.0_i386.iso of=/dev/sdb

Once you’ve burned the DBAN ISO to a CD or USB drive, you can boot from it and follow the instructions to erase the hard drive.

3. Use a Secure Erase Utility

If you’re using a solid state drive (SSD), then you should use a secure erase utility instead of a file shredder or disk eraser. This is because SSDs use a different type of storage than regular hard drives, and as a result, they can’t be securely erased using the same methods.

Fortunately, there are a few different secure erase utilities available that will work with SSDs. One of the best is the hdparm utility. To install it, just open up a terminal and type in the following command:

sudo apt install hdparm

Once it’s installed, you can use it to securely erase an SSD by running the following command:

sudo hdparm –security-erase ENABLE /dev/sda

Replace “/dev/sda” with the path to your SSD. This will enable the security erase feature on the SSD, which will allow you to erase the drive using the following command:

sudo hdparm –security-erase-enhanced SECURITY-ERASE-PASSWORD /dev/sda

Replace “SECURITY-ERASE-PASSWORD” with the password that you want to use to erase the SSD. Once you’ve done this, the SSD will be securely erased.

Conclusion

These are just three of the many different ways to securely erase a hard drive on Linux. Which method you should use will depend on your specific needs. However, all of these methods will securely erase the data on the drive, so you can rest assured that your sensitive data will be gone for good.

To do a clean install, first you’ll need to create a bootable USB drive or DVD with the Ubuntu installer. Then boot from that drive and follow the prompts. When you get to the part of the installer where it asks you where to install Ubuntu, choose the “Erase disk and install Ubuntu” option.

Be very careful with this option, as it will completely erase everything on the selected hard drive. If you have any data on the drive that you want to keep, make sure to back it up before proceeding.

Once you’ve confirmed that you want to do a clean install, the process is fairly straightforward. Ubuntu will be installed and you’ll be prompted to set up your user account. After that, you’ll be able to use Ubuntu as you would any other operating system.


How do I completely wipe my hard drive and operating system?

When you want to wipe your hard drive clean, there are two ways to do it. The first is to use a data destruction software program that will completely erase your hard drive, including the operating system. The second way is to physically destroy the hard drive.

If you want to make sure that your data is completely gone, and that no one will be able to recover it, then you should use a data destruction software program. These programs work by overwriting all of the data on the hard drive, including the operating system, with random data. This makes it impossible to recover any of the original data.

There are many different data destruction software programs available, and they all have their own advantages and disadvantages. Some programs are free, while others cost money. Some programs are very quick and easy to use, while others are more complex and take longer to use.

The best way to find the right data destruction software program for you is to read reviews of the different programs. You can find these reviews online, or in magazines and newspapers. Once you’ve found a few programs that you’re interested in, you can download them and try them out.

If you don’t want to use a data destruction software program, or if you can’t find one that you’re happy with, then you can physically destroy your hard drive. This can be done by crushing it with a hammer, or by drilling a hole through it.

If you’re going to physically destroy your hard drive, then you need to make sure that you do it in a safe way. You don’t want to damage any other parts of your computer, or to put yourself in danger.

When you’ve destroyed your hard drive, you’ll need to install a new operating system. You can either install a new copy of Windows, or you can use a Linux distribution.

If you’re installing a new copy of Windows, then you’ll need to format your hard drive. This will erase all of the data on the hard drive, including the operating system. After you’ve formatted the hard drive, you can then install the new operating system.

If you’re using a Linux distribution, then you can use a tool called “DD” to erase the hard drive. This tool will overwrite all of the data on the hard drive, including the operating system. After you’ve used DD to erase the hard drive, you can then install the new operating system.
