How to make a dual booting system containing Windows and Linux ?

Hello !

I cannot install Linux in a system containg Windows Xp as well. Whenever I try to partition the free space, after allocating 2 partitions it is showing an error message for the 3rd "Cannot allocate partition" irrespective of the size of the partition.

Kindly help. Also please give the probable solution to install Redhat Linux in a dual booting system.

P.S. My Windows machine is having 4 partition "C", "D", "E", "F"

Also please note down that while partitioning the system I have made 10 GB of Free space for installing Linux.

Please read;

You Windows drive letters "C", "D", "E" and "F" mostly likey are;

The first primary partition known by Windows as your "C" drive.

An expanded partition which contains three logical partitions known by Windows as your "D", "E" and "F" drives.

This means you have two partitions left that you can use to create and use for Linux, one for everything (the root [/] partition) except the swap parition and the swap partition.

It depends on how your drive is partitioned. Typically windows will create a primary for C and logicals partitions for D,E and F. I would guess that your entire extended partition is being used for logical drives D, E and F. C and the extended partition are using primary partitions 1,2. This leaves only 2 free primary partitions for linux. The auto installer wants to create 3 partitions. /, /boot and a swap partition.

A hard drive can only have 4 parimary partitions. However a primary partition can be designated as an extended whereby additional drives called logicals are located. So an IDE drive can be divided into 64 partitions. If you resize the extended partition to include the 10GB of free space the auto installer will then be happy.

The other solution if you are not wanting to modify existing partitions would be to manualy create 2 partitions and assign them / and swap.
