Shalom chinna,

To answer this question, one would need to know what distribution of Linux you are actually using.

For RedHat and similar:

rpm -Fvh

or

rpm -Uvh

Note that you can break certain applications such as IBM rational clearcase by doing this upgrade.

It's not so easy to upgrade kernel from 2.4 to 2.6. I'll suggest you or stay with your current distibution, or upgrade the whole system to some moder distro - to RHEL 4 (or CentOS 4), for example.

In case that you are really really sure that you want to update your kernel from 2.4 to 2.6, you can start by reading the following document: http://kerneltrap.org/node/799
However, IF you are running a distribution which has a package management system, you might solve everything easier using it (something similar to up2date / yast / yum / apt-get will update all required dependencies when upgrading the kernel). But, unless you really know what you are doing, I would recommend against upgrading ONLY the kernel, although it can be done.
By all means, if possible, follow Vitaly's recommendantion and upgrade the whole system to a newer distro which uses kernel 2.6 by default.

I think that the best option would be to create a chroot on /mnt/hdc6. But all depends on your actual configuration and you have not provided enough details for a pertinent advise.

Please bear in mind that there is no limit in the number of kernels installed at the same time in a system, but one and only one of them can be used at a given time (that is, leaving virtual machines alone)

If you have a spare space on your harddisk, I'll suggest you to install second distribution with multi-boot.

i made a copy of linux with commmand fdisk -n
Device Boot Start End Blocks Id System
/dev/hdc1 * 1 13 104391 83 Linux
/dev/hdc2 14 523 4096575 83 Linux
/dev/hdc3 524 1798 10241437+ 83 Linux
/dev/hdc4 1799 2438 5140800 f Win95 Ext'd (LBA)
/dev/hdc5 1799 1862 514048+ 82 Linux swap
/dev/hdc6 1863 2163 2417751 83 Linux

i m currently booted /dev/hdc3 but i want make kernel version change in /dev/hdc6 .without booting into /dev/hdc6 how can i change kernel from /dev/hdc3
can i use following commands
#mount /dev/hdc6 /mnt
#cd /mnt
#cd /mnt/usr/src/linux-2.6.10
rest are kernel compilation commands

I suggest you not upgrade kernel on hda6, but just install some modern distro instead.
