How can i increase hard disk space
 

I have 40 GB hard disk .But i have allocated 30 GB only for linux.I have remaining 10 GB freespace for dual purpose.But now the space for linux OS is full.How can i increase hard disk space for linux using existing freespace?

man fdisk
man mkfs

just create a parition table and write a filesystem to the drive.

Assuming you are using ext2 file systems...

As suggested you can create a new filesystem in the partition. If you are braver and know you way around patitioning etc you can delete the 10g partition, make the 30g one bigger, and then use resize2fs (man resize2fs). I don't have precise instructions to hand, but a google search on linux partitioning and resize2fs might turn up some more info. BE VERY CAREFUL when playing with patitions - write all config data down so you can put it back if you have to.

You may also wanto look at gnu parted.

As mentioned above, be careful and read the docs.

the thread is important
 

I have met a similar situation recently; I want to increase my partition space in windows 7. I found the tool built-in windows 7 could not help me solve my problem. Because there is not unallocated space beside my system partition. I googled and found one free partition software, easeus partition master. I used it to drag D drive to shrink it and let some unallocated space beside my system partition. Then I increased it. It is so mazing!

Hi,

Welcome to LQ!
Please do not resurrect 8 year old threads.

Your post is Not really a Linux specific problem but a Microsoft issue. You could use the Microsoft disk management tool to shrink partitions. Along with other tools to move or copy partitions.

You should re-read LQ Rules:Your query should have been created in <General> because of Microsoft specifics.
