When listing the current and new kernels in the command, it is not necessary to write the entire version numbers. For example, any version of Kernel 3.4 can be listed simply as 'linux34', and any version of Kernel 3.5 can be listed as 'linux35', and so on. | When listing the current and new kernels in the command, it is not necessary to write the entire version numbers.

'''The use of the 'yes' or 'no' option at the end of the command is of vital importance:''' | |||
* Entering ''yes'' will result in your existing kernel being deleted upon the installation of the new kernel. | * Entering ''yes'' will result in your existing kernel being deleted upon the installation of the new kernel. | ||
* Entering ''no'' will keep the existing kernel, and allow it to still be selected alongside the new kernel at the boot screen. | * Entering ''no'' will keep the existing kernel, and allow it to still be selected alongside the new kernel at the boot screen. | ||
It is recommended - especially if updating to the latest bleeding edge kernel - to keep your old one, if only for a short time afterwards. This the safer option, and the old kernel can be easily removed when satisfied with the stability and functionality of the new one. As an example, once the terminal is opened, the following command will install the latest version of kernel 3.6 '''without deleting the existing kernel version 3.5 currently being used''': | |||
sudo mhwd-kernel linux35 linux36 '''no''' | |||
Otherwise, the following command will install the latest version of kernel 3.6 to replace the existing kernel version 3.5, '''which will be deleted''': | Otherwise, the following command will install the latest version of kernel 3.6 to replace the existing kernel version 3.5, '''which will be deleted''': | ||
