Step by Step guide installing Ubuntu 10.10 on a Windows 7 System (Dual booting)

First I completely formatted the hard disk
Second I made three partitions in hard disk (C, D & E)
In partition C, I installed windows 7 (First windows should be installed in newly formatted hard disk)
And in partition E, I installed Ubuntu 10.10

For Installation Windows 7 here the step by step method

Setting up your computer and BIOS (Changes if Required)

When you start your computer put your Windows 7 DVD in DVD drive. And Restart

In most cases it will automatically boot in to the Windows 7 installation.

But in some cases Boot device order has to change.

BIOS it may boot you’re running operating system. In that case you will need to change the BIOS. You change the BIOS setting to boot from CD/DVD instead boot from hard drive.

Booting UP and First Installation steps

Installation of Windows 7 almost like Vista Installation type. But you have to care full read the descriptions in each time before clicking the NEXT button to avoid and disasters. There are options to choose in these steps you may find them with each images.

a) You choose your Language options by ‘Language to install’, ‘Time and Currency format’ and ‘Keyboard or input method’ here.

b) This screen is where the installation wizard begins. The install now options will leads to the

Advanced install options. For repairing a corrupt installation the ‘Repair your computer’ button

Located at the bottom-left can be used. For fresh installs just click the Install now button.

Windows might create additional partitions for system files. This is a new feature in Windows 7 to have a small boot partition for system files.

f) Click Ok to continue.

g) Select the partition you just created and click next to continue.

The Windows 7 installation begins. Wait for 15 - 30 minutes for the all new OS! at installation time it will ask to give password, time setting etc.. Like in vista you have to give it.

How to install Ubuntu 10.10

Now again you go to free space and press /home give 4000 and press OK like that you have to give all partitions. After all partitions allocated is over now you have to give /swap partition.

The size of /swap partitions is 2 times of your Ram (Exp:- RAM is 1 GB you have to give 2GB (2000) as /swap partitions

And finally / (ROOT) reaming available free space you have to give for / (ROOT) partition.

And press “Install Now” button
