First off I am using Linux Ubuntu program the lastest version.

For my first question that I have I have mounted a few devices and I want to know the command for displaying the mounted devices and the format of each device. I know that mount has to be at the beginning of the command but I'm not sure what else I'm missing because it's not showing the format of each device.

Secondly
Another mount question. I was wondering devices that contain the operating system must be mounted at the mount point of what? I was looking at my book that I have and said it had to be the root directory. I am just making sure that I'm right.

Thirdly
This question I have been looking all over in my book and on my linux ubuntu program that I have to find; where the boot loader is located on a system with multiple partitions?

Thank you in advances for any advice you can give me.. Thank you!

You can probably use the 'mount' command without any arguments to display the devices and the format of each device. Looking at /etc/fstab can also provide the same information.

AFAIK, the device can be mounted anywhere. You can then use chroot.

It depends on how the system was set up. The boot loader can be in the MBR of a device or in any of the partitions. You can probably determine the location by looking at the boot configuration files (e.g., grub.conf if you are using the GRUB bootloader).

Good luck!
