Recovering Ubuntu After Installing Windows

This option will use the Desktop/Live CD to install Grub into your MBR (Master Boot Record). This option will overwrite your Windows Boot Loader.


1. Boot the Desktop/Live CD. (Use Ubuntu 8.04 or later)

2. Open a terminal (Applications -> Accessories -> Terminal)

3. Start grub as root with the following command :

sudo grub

4. You will get a grub prompt (see below) which we will use to find the root partition and install grub to the MBR (hd0)

[ Minimal BASH-like line editing is supported. For
the first word, TAB lists possible command
completions. Anywhere else TAB lists the possible
completions of a device/filename. ]

grub>

Type the following and press enter:

find /boot/grub/stage1

If you get "Error 15: File not found", try the following:


find /grub/stage1


Using this information, set the root device (fill in X,Y with whatever the find command returned):

grub> root (hdX,Y)

Exit Grub:

grub> quit

5. Reboot (to hard drive). Grub should be installed and both Ubuntu and Windows should have been automatically detected.

6. If, after installing grub, Windows will not boot you may need to edit /boot/grub/menu.lst (That is a small "L" and not the number 1 in menu.lst)

Open a terminal and enter :

gksu gedit /boot/grub/menu.lst


Or, in Kubuntu:

kdesu kate /boot/grub/menu.lst

Your Windows stanza should look something like this :

title Windows XP/Vista # You can use any title you wish, this will appear on your grub boot menu
rootnoverify (hd0,0) #(hd0,0) will be most common, you may need to adjust accordingly

Reliance Netconnect USB card on Linux - Howto

Execute everything as root

Check your card is recognized by the kernel

Code:
# cat /proc/bus/usb/devices

Now modprobe the driver

Code:
# modprobe usbserial vendor=0x12d1 product=0x1001

Should get something like this with dmesg
Code:
# dmesg
[ 2315.412106] usbcore: registered new interface driver usbserial

Now edit your wvdial.conf file

Code
# vi /etc/wvdial.conf

[Modem0]
Modem = /dev/ttyUSB0
Baud = 115200
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)
[Dialer cdma]
Username = You Phone Number Here
Password = Your Password ... usually same as your phone number
Phone = #777
Stupid Mode = 1
Inherits = Modem0

Now run wvdial

Code:
# wvdial cdma
--> WvDial: Internet dialer version 1.56
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Modem initialized.
--> Sending: ATDT#777
--> Waiting for carrier.
ATDT#777
CONNECT 230400
--> Carrier detected. Starting PPP immediately.

--> remote IP address 97.239.2.10

--> secondary DNS address 202.138.96.2

Thats it ... you are now connected
Ensure that your internet traffic goes through your "Modem"
In Ubuntu ... this can be done @ System->Administration->Networking
