On a Microsoft Windows system, chances are low that the right set of tools to verify checksums and cryptographic signatures are in place. To first verify the cryptographic signature, tools such as GPG4Win can be used. After installation, the public keys of the Gentoo Release Engineering team need to be imported. The list of keys is available on the signatures page. Once imported, the user can then verify the signature of the. The checksum itself can be verified using the Hashcalc application , although many others exist as well.
Most of the time, these tools will show the user the calculated checksum, and the user is requested to verify this checksum with the value that is inside the.
With this package installed, the following commands can be used to verify the cryptographic signature of the. First, download the right set of keys as made available on the signatures page :. Alternatively you can use instead the WKD to download the key:.
Next verify the cryptographic signature of the. To be absolutely certain that everything is valid, verify the fingerprint shown with the fingerprint on the Gentoo signatures page. With the cryptographic signature validated, next verify the checksum to make sure the downloaded ISO file is not corrupted. For instance, to get the SHA checksum:. In the above output, two SHA checksums are shown - one for the install-amdminimal Only the first checksum is of interest, as it needs to be compared with the calculated SHA checksum which can be generated as follows:.
The ISO file needs to be burned on a CD to boot from, and in such a way that its content is burned on the CD, not just the file itself. Versions of Microsoft Windows 7 and above can both mount and burn ISO images to optical media without the requirement for third-party software.
Simply insert a burnable disk, browse to the downloaded ISO files, right click the file in Windows Explorer, and select "Burn disk image".
Once the installation media is ready, it is time to boot it. Insert the media in the system, reboot, and enter the motherboard's firmware user interface. The 'trigger' key varies depending on the system and motherboard. If it is not obvious use an internet search engine and do some research using the motherboard's model name as the search keyword. Results should be easy to determine. Without this change, the system will most likely reboot to the internal disk device, ignoring the external boot media.
If not yet done, ensure that the installation media is inserted or plugged into the system, and reboot. A boot prompt should be shown. At this screen, Enter will begin the boot process with the default boot options. To boot the installation media with custom boot options, specify a kernel followed by boot options and then hit Enter. At the boot prompt, users get the option of displaying the available kernels F1 and boot options F2.
If no choice is made within 15 seconds either displaying information or using a kernel then the installation media will fall back to booting from disk. This allows installations to reboot and try out their installed environment without the need to remove the CD from the tray something well appreciated for remote installations. Specifying a kernel was mentioned. On the Minimal installation media, only two predefined kernel boot options are provided. The default option is called gentoo.
The other being the -nofb variant; this disables kernel framebuffer support. Now boot the media, select a kernel if the default gentoo kernel does not suffice and boot options. As an example, we boot the gentoo kernel, with dopcmcia as a kernel parameter:.
Next the user will be greeted with a boot screen and progress bar. If no selection is made in 10 seconds the default US keyboard will be accepted and the boot process will continue. Once the boot process completes, the user is automatically logged in to the "Live" Gentoo Linux environment as the root user, the super user.
The new partitions probably align with previously existing partitions that had filesystems on them. Some filesystems signatures like those of ZFS can coexist with other signatures and may cause blkid to find ambiguous information. Skip to content. Star MIT License. Branches Tags.
