Because we install the other o/s before the LINUX it takes the hdd address after the partitions of the first installed O/S

BUT THE BOOT LOADER OF THE LINUX IS INSTALLED IN THE LAST PARTITION OF THE OTHER O/S SO IF YOU DELETE THE LAST PARTITION OF THE OTHER O/S THE BOOT LOASDER GRUB  IS AUTOMATICALLY DELETED THEN YOU HAVE TO
REINSTALL THE GRUB BY { grub-install /dev/sda} comnd

RESET ROOT PASSWORD IN UBUNTU



There are many reasons you might want to reset a password

  • Someone gave you a computer with Ubuntu installed on it but not the password for the user account.
  • You just installed Ubuntu and forgot what password you selected during the installation process.
  • You have too many passwords in your life and can't keep track of them all.
Well, this tutorial will help you reset your Ubuntu user account password, regardless of what reason you have for resetting it.
First, you have to reboot into recovery mode.
If you have a single-boot (Ubuntu is the only operating system on your computer), to get the boot menu to show, you have to hold down the Shift key during bootup.
If you have a dual-boot (Ubuntu is installed next to Windows, another Linux operating system, or Mac OS X; and you choose at boot time which operating system to boot into), the boot menu should appear without the need to hold down the Shift key


After you select recovery mode and wait for all the boot-up processes to finish, you'll be presented with a few options. In this case, you want the Drop to root shell prompt option so press the Down arrow to get to that option, and then press Enter to select it.



The root account is the ultimate administrator and can do anything to the Ubuntu installation (including erase it), so please be careful with what commands you enter in the root terminal.
In recent versions of Ubuntu, the filesystem is mounted as read-only, so you need to enter the follow command to get it to remount as read-write, which will allow you to make changes:
mount -o rw,remount /



ls /home
That's a lowercase L, by the way, not a capital i, in ls. You should then see a list of the users on your Ubuntu installation. In this case, I'm going to reset Susan Brownmiller's password.
To reset the password, type
passwd username
where username is the username you want to reset. In this case, I want to reset Susan's password, so I type
passwd susan
You'll then be prompted for a new password. When you type the password you will get no visual response acknowledging your typing. Your password is still being accepted. Just type the password and hit Enter when you're done. You'll be prompted to retype the password. Do so and hit Enter again.
Now the password should be reset. Type
exit
to return to the recovery menu. 


After you get back to the recovery menu, select resume normal boot, and use Ubuntu as you normally would—only this time, you actually know the password!
