Connect the Labtix Bootable USB pendrive inside one of the USB ports of the computer that you want to sanitize. Start the computer and verify that the Labtix software boots correctly. You will know that it has booted correctly if you see the following screen:
|Figure 1. Initial Labtix screen when a computer is booted.|
If you don't see the above screen, it most likely means that you need to modify the boot order to ensure the computer correctly loads the Labtix software in the USB pendrive. In this case, please follow the instructions in this wiki page to change the boot order of the computer and ensure that the USB drive is selected as the first booting device. After this step, reboot the computer again and check that Labtix is now correctly booted according to the screen shown in Figure 1 above.
Upon reaching the screen in Figure 1, select the first option "antix" and press enter. This will take you to the next screen:
|Figure 2. In this view, double click on the icon 'Labdoo installer'.|
Note that in the upper-right corner of the screen you will see a summary of the key parameters extracted from the laptop. It includes the following information:
- Vers: the version of the Labtix software that you are using. In Figure 2, this value is 1.01.
- CPU: the type of CPU (32bit or 64bit). In Figure 2, this value is 64 bit.
- Boot: The name of the booting USB device where Labtix is running. In Figure 2, this value is sr0.
- RAM: The amount of memory in the laptop. In Figure 2, this value is 2703 MB.
- Sdx: The name of the hard drive where the Labdoo image is to be installed and its size. In Figure 2, the name of the disk is sda and it has 100GB of storage.
In the above screen, ensure that you select the name of your computer's hard drive. This name is typically of the form Sdx (for instance, sda, sdb, sdc, etc.), although it could be a different name too depending on the computer. The actual name can be found in the 'Sdx' field located in the upper-right corner of the screen. For instance, in Figure 2, the name of the hard drive is sda. To be sure that this corresponds to the actual hard drive of your computer, you can also double click on the application GParted, which will show you all the drives attached to your computer.
Click on OK, this will take you to the next screen:
|Figure 3. Parameters needed to initiate the installation.|
In this screen, you will need to specify the following parameters:
- Shred: This option specifies the number of times the hard disk must be shredded prior to initiating the installation of the image. The operation of shredding consists in writing random zeros and ones everywhere in the hard-drive to ensure any prior personal information is completely erased. Labdoo recommends setting this value to 3, so that three full shreds are carried out, ensuring that all existing information is erased.
- Target disk: This corresponds to the name of the disk that you introduced in the previous screen (see Figure 2), which corresponds to the disk in the computer where the image will be installed.
- Disk size: This field specifies the size of the chosen disk. You need to use this size to determine the image you can install by making sure you don't select an image larger than this value. For instance, in Figure 3, the size of the chosen disk (sda) is 100GB. So you need to make sure you don't install an image that is larger than 100GB.
- Choose and image: In this step you select the image to install. Click on this field, then select the option "Other...", and browse through the directory tree to select the image you want to install. In the directory tree, make sure you go into the external drive where you have the images installed, and travel to the directory where you have the image. Then, click "Open". This will populate the field "Choose and image:" with the right path to your selected image. As mentioned in the previous parameter, make sure you select an image that is smaller than the size of the disk shown in the previous "Disk size" parameter. By convention, the size of the image corresponds to the last value in the image name. For instance, the image PAE64_20_04_LTS_EN_80 has a size of 80GB and can only be installed with disks that at least have 80GB of storage.
- Hostname:This field corresponds to the hostname that will be assigned to the computer after the image has been installed. By convention, please choose always a name of the form 'labdoo-XXXXXXXXX', where XXXXXXXXX is the 9-digit Labdoo ID of the computer you are sanitizing, which you had previously generated in the section 'Tagging a Laptop'.
After you have populated all the parameters above, click "OK" on all the next screens. Then the actual process of shredding and installation of the selected Labdoo image will initiate. Notice that this process could take long, even more than an hour, depending on the size of the disk and the size of the selected image.
