Hi,
try pressing the power button and holding it for 10 seconds. Then wait a while. Turn it back on, you may press F12 or other key when the Samsung Logo appears (before Windows Logo) to see the boot options. Choose the one to check for any errors or anything else - Run diagnostics. Then also you may scan your hard drive for any failures.
Testimonial: "Thanks for that - it got me out of the original loop but then went to a screen to do pre-boot eXecution, then said media test failed, then exited and went back to original loop."
In Ubuntu 9.04 click on the main icon and select Restart.
- If Ubuntu is the only operating system on your computer you'll need to tap the ESC key as the system boots.
- If you have a dual boot or multiple-boot system the menu should appear on its own.
- At the root level you'll get a boot menu. Select the one that says "recovery mode" and press Enter.
- Ubuntu continues to load until you reach the Recovery Menu.
- Arrow down to "
netroot
" which states Drop to root shell prompt with networking and press Enter.
- Now, at the root type "
password username
" (where username is the account whose password you want to change) and press Enter.
- You'll be prompted to
enter a new password
.
- You will not see the password or any evidence that you are typing.
- Retype the password. If both passwords match you'll have successfully reset your password.
- Press Enter to continue booting into Ubuntu.
hope it helps
