need help for manual partitioning

[Debabratacse]

what will be the size of /boot,/,/home mount point during manual partitioning for installation of ubuntu 9.04.which of these are mandatory?

I personally don't use a separate partition for boot, only for /home, 10gb should be enough for the / partition, then allocate the rest for /home

I agree with coopstah. /boot partition is not necessary unless you are planing to use LVM.

* SWAP - 1GB is ebough
* / - 10+GB
* /home - as much space as you like. /home folder is for user's personal documents.

A separate boot partition needs to be large enough to hold the kernel, and you'll probably want room for a backup kernel as well. Recommendations generally range from 32mb to 100mb. 100 seems a little large to me, I would say go with a middle ground and do about 50mb.

You aren't required to have separate partitions at all. It's entirely possible to do one large partition for everything. (Except swap.)

I generally do a separate /home partition, because it makes it easier to reinstall if I want, or install a different distro.

EDIT: Agreed with the others though that there is no real reason to have a separate boot partition. Unless you install Fedora and want ext4 partitions. Fedora doesn't currently support booting from ext4, so you need a separate ext3 boot partition.

Welcome to the forums!

Only the root ( / ) partition is necessary out of those you mentioned above. I usually make my root partition about 8 to 12 GB, ext3 filesystem, and a /home partition of about the same size or larger.

Hope you enjoy running Linux.
