On devices which boot from internal NOR- or NAND-flash memory, flash-kernel writes the kernel and the initial ramdisk to this internal memory. This method is particularly common on older armel devices. Please note that most of these devices do not allow having multiple kernels and ramdisks in their internal flash memory, i.e. running flash-kernel on them usually overwrites the previous contents of the flash memory! 

For ARM systems that use U-Boot as their system firmware and boot the kernel and the initial ramdisk from external storage media (such as MMC/SD-cards, USB mass storage devices or IDE/SATA hard- disks), flash-kernel generates an appropriate boot script to allow autobooting without user interaction. 

## 6.3.6.3. Continue Without Boot Loader 

This option can be used to complete the installation even when no boot loader is to be installed, either because the arch/subarch doesn’t provide one, or because none is desired (e.g. you will use existing boot loader). 

If you plan to manually configure your bootloader, you should check the name of the installed kernel in /target/boot . You should also check that directory for the presence of an initrd ; if one is present, you will probably have to instruct your bootloader to use it. Other information you will need are the disk and partition you selected for your / filesystem and, if you chose to install /boot on a separate partition, also your /boot filesystem. 

## 6.3.7. Finishing the Installation 

This is the last step in the Ubuntu installation process during which the installer will do any last minute tasks. It mostly consists of tidying up after the debian-installer . 

## 6.3.7.1. Setting the System Clock 

The installer may ask you if the computer’s clock is set to UTC. Normally this question is avoided if possible and the installer tries to work out whether the clock is set to UTC based on things like what other operating systems are installed. 

In expert mode you will always be able to choose whether or not the clock is set to UTC. 

At this point debian-installer will also attempt to save the current time to the system’s hardware clock. This will be done either in UTC or local time, depending on the selection that was just made. 

## 6.3.7.2. Reboot the System 

You will be prompted to remove the boot media (CD, floppy, etc) that you used to boot the installer. 

After that the system will be rebooted into your new Ubuntu system. 

## 6.3.8. Troubleshooting 

The components listed in this section are usually not involved in the installation process, but are waiting in the background to help the user in case something goes wrong.
