Adjust Grub menu

This is to move Windows before Ubuntu.

Enter root user mode and goto directory /etc/grub.d/:
```
 sudo -i
 cd /etc/grub.d
 ls -l
```
Adjust order of loader files.

Find the Windows loader file (In this condition, it is 30_os-prober). Move it before Linux loader (10_linux) by changing its name. Change the number prefix only. Do not touch any other part of the file name.
```
 mv 30_os-prober 08_os-prober
 mv 30_uefi-firmware 08_uefi-firmware
 ls -l
```
Set menu item timeout
```
nano /etc/default/grub

GRUB_TIMEOUT=5
```
To make it effective, update the grub:
```
update-grub
exit
```

Adjust Tooltip colors

The default tooltip background color is black while default foreground color is white.

Open the current theme's setting file with text editor:
```
sudo gedit /usr/share/themes/Ambiance/gtk-2.0/gtkrc
```

Locate the first line and change values as follows:

 tooltip_fg_color: #000000
 tooltip_bg_color: #f5f5b5

Save the settrings. Sometimes you have to re-login to make if effective
