Screenlets are small applications to represent things such as sticky notes, clocks, calendars around on your desktop. You can launch a pre-installed screenlet from Screenlet Manager, or install a new one into the Manager for launching it. Here are the steps for installing and launching a screenlet, for example, WaterMark System Information.

1. Install Screenlets Manager if it has not been added.
   1. Go to Applications (or Main Menu) > Ubuntu Software Center.
   2. Enter screenlets in the Search Box.
   3. Select Screenlets, click the “Install” button.
2. Download the screenlet “WaterMark System Information” to a folder.
3. Go to Applications (or Main Menu) > Accessories > Screenlets.
4. Click Install, select Install Screenlet and click OK.
5. Browse to the folder, select the file downloaded and click “Open” to install the screenlet into the Screenlets Manager.
6. Select the screenlet “WaterMark” and click “Launch/Add”. (Tips: you can add more than one WaterMark screenlet and set it to display other system information.)

In this issue machine  have the two hard drives. On one is Windows XP , on the other one is Xubuntu 12.04 .

Here the windows MBR is fine. I can boot my Windows partition by selecting that HD from the BIOS. Likewise the MBR on the other hard drive is fine and I can boot Xubuntu from grub. What I would like to do is to be able to chainload ntldr (I believe that’s the right terminology) from grub.

os-prober does not detect Windows – unless the partition is mounted but it can’t write anything anyway because it says it needs to be run as root. However sudo os-prober doesn’t seem to do anything at all, so that doesn’t help either. Always getting below error.

ERROR: you must be root ERROR: you must be root /usr/lib/os-probes/mounted/20microsoft: 47:

/usr/lib/os-probes/mounted/20microsoft:

cannot create /var/lib/os-prober/labels: Permission denied /dev/sda1:Microsoft Windows XP Home Edition:Windows:chain mkdir: cannot create directory `/var/lib/os-prober/mount': Permission denied

I have followed below steps for resolve the issue

Added the following to the lines below those already in /etc/grub.d/40_custom:

Save the file and update-grub.

Reinstalled os-prober with the following:

sudo apt-get install --reinstall os-probe
