    thank you for giving the valuable advice and guidance.

    i know about about the inbuilt partition manager,but it wont allow me to resize my linux partition as it is mounted currently .i have to try ubuntu live cd,or gparted boot cd for resize it.and importantly the first step i am going to backup my data.once again thank you very much for all.



  • Harish Rajagopal Jan 01, 2009


    i did it....

    i downloaded gparted live .iso image file and burnt it on a cd and booted.i got options for resizing all the partitions and i did it.

    now it is working wonderfully.

Unbuntu has a partition manager but you are better off using a partition manager that runs from a boot screen and can handle all the partition types such as Linux (depending on how you have this formatted), NTFS for Windows and FAT32 if you are using one.

In the past, with Linux, I found that reinstalling the software (Ubuntu) gives you the ability to resize partitions if you choose this option, but tread carefully and allow Ubuntu to perform an upgrade. As an upgrade install most of everything will be there when you are done. But, handling the partition tools in Linux is very tricky I would use the forum at to learn more and get specific advice on your version of Ubuntu. It is all pretty hairy so making a clone backup of your drive is essential.

Lets say you have a 250 GB hard Drive now. If you cloned that disc onto a 500 GB drive your partitions will automatically resize themselves during the disc clone. How Ubuntu responds to this is in question. I believe on reboot into Ubuntu that linux will handle the new start and stop partition edges on its own without any interaction from you. But, I stongly suggest you join up at, its still free last I knew, and ask these questions there. There are plenty of Linux users here too and you can let this question ride on the forum for a while before moving on.

It is therefore highly advisable that you clone your hard drive to another hard drive as an image backup. Then resize your partitions using a partition manager. There are many free tools that are rated High in Tech Ability that you can find starting at Majorgeeks dot com. To reiterate, backup your entire disk using a clone tool. Since this would require an entire new hard drive and since you need this for Windows. I would really suggest you purchase another hard drive, add it onto your IDE or SATA bus cables and then you have this extra space that you can allow Windows to have more and Ubuntu to have more.

The reason I'm writing all this is to advise you of the troubles and an easy path to pursue for a resolution. You will want to get up to speed on partition management, resizing and cloning. All this is well written on Wiki and that is an advisable place to start. Before you do anything, again backup your entire drive and then practice first to experiment with the tools.

Before you buy anything that is going to cost good money, software wise, try to borrow a copy of Acronis Ulitmate Boot CD, Hiren's Boot CD and get familiar with the tools on these discs and practice. When you find the one you prefer and want to own a copy, then by all means purchase one to use and suit your needs.

Bottom line: To do what you want, you will need to aquire another equal or larger hard disk to back up your current one. Two, decide if just adding another hard disk and cloning that over will solve your problems. (Probably the easiest smartest track to persue). Three borrow copies of Acronis or Hiren's and practice using these partition managers and cloning tools. This in the end will cost you quite a bit of money. In the end I'd just get another hard disk and let Windows have the space.

Get another larger hard rive about three times the size you have now, learn cloning procedures and the free tools out there to do this and clone your drive over to the new one. That will solve all your problems even though you will/may have to reinstall Ubuntu as an upgrade after (that is questionalble, I belive I always have in the past, its just been a while since I need to on my Linux Box.)

    Glad to hear of your success. I usually use other boot up partition managers to resize, but since the Gparted iso worked for you as a stand alone bootup program then, burn a copy and file that away for future use. I'm going to grab a copy for my own tool kit.

    There are a few all around partition managers that will resize almost any OS partition. Those are good programs to have in your toolkit.

    Isn't it funny how you kick yourself and wish you had bought a larger hard drive? Right now I keep looking at these 1TB and larger drives but know the 2 and 3 TB are around the corner and then there as to be some other breakthrough. I think we'll see it with SSHDs soon, they are very close the unleashing the data transfer bottle neck because the Space Program here and in other countries are all now dependent on SSHDs. I can't wait to see that technology trickle down to we users.

    Good Luck. Glad to hear it all worked out for you. So many times our customers fail; way to hang in there.

    Thanks for the Helpful rating, I'd really appreciate a FixYa if you feel up to handing one out. It means a lot when I put a real effort into a problem that ultimately empowers you to obtain a solution, even when on your own. I think you can appreciate that.

    And, in the end I would encourage you to get a larger hard drive and clone your old one on to that. The new one should be three times the size of your current hard drive. You can use your current one later as a backup drive.

Just in case you didn't know, the program in Ubuntu to do partition related stuff is called gparted. Usually it's located under menu system/administration/partition editor
If you want to alter your linux partition, then you need to boot from the CD and run gparted from the CD. The graphical interface of gparted is okay, pretty comprehensive. However, before you do something with your HDD, be sure to backup first.
One last thing, NEVER give a label to your harddisk using gparted. Label in linux and dos/windows are totally different.

Hope this helps

Want to unistall ubuntu 12.04 from hp sleekbook and install windows 8.1. pls help

Assuming you have your windows 8.1 on disks, make sure your HP is set to boot from disk and put disk in and boot your computer up. The windows install should start and you can choose to delete Ubuntu and install windows. Remove any partitions that it displays and choose to install windows on the entire disk. After that just follow the prompts and windows will install.

Uninstall os linux ubuntu 13.10 from my laptop

Are you dual booting? Windows and Ubuntu? What version of Windows? You maybe able to reclaim the space by using the Disk Management (right click "My Computer" select Manage then select Disk Management). In there you will see NTFS for your Windows partitions, and something like Unknown for the linux ones, you can then delete the linux partition and possibly extend your NTFS partition to use the free space (depending on version of windows).
If this is a standalone Ubuntu install, you should be able to just use the installer disk for another OS and boot it to reformat the drive.
good luck!

I want to install ubuntu and Mandiva, my question how to Install both operating systems? Thanks

The answer is yes, and no.
Both Mandriva and Ubuntu are Linux based and they do have
similarities and differences. The differences in how things run
may cause you problems, so the easy answer is no. There are
similarities that can be shared, and in this case, you have a

Since you mention XP and Ubuntu halves above, I'll assume you
have your harddrive split in only 2 partitions, perhaps or
preferably 3 partitions, such as.
hda1 = C: = XP ntfs (maybe 15 to 40 GB in size)
hda5 = extended partion which holds Ubuntu and swap
hda6 = = Ubuntu (maybe 4 GB or bigger and includes home)
hda7 = swap (approximately 2x the size of your RAM)

First, we begin by describing your hard drive geometry.
When IBM compatible PC computers came into existence, the hard
drives had definitions allowing the harddrive to be divided into
4 separate partitions. 1 of the 4, could be allocated as
an "extended" partition which could be divided further into many
more partitions. In the past, this allowed you to have 4
distinctly different operating systems on your harddrive, or 3
distinctly different operating systems and an extended partition
for extended drives, so in the past, it was possible to have
combinations such as DOS, Win95, OS2, and shared extended drives.
There were additional limitations, but based on you
describing "halves", your computer does not have the 1024
cylinder problem of long-ago and you are running a more modern
computer with a modern BIOS.

XP does want to be the 1st operating system on the 1st
enabled "primary" partition, so let us leave that as it is since
linux is more flexible and can be put on the extended partitions.

From a linux perspective, the primary reserved definitions would
be 1,2,3,4 (XP will me located in one of these 1..4) and the
extended partitions are 5 to define the partition, then
6,7,8,9.... (your Ubuntu will be located on one of these 6...).

Due to some very old software having had problems in the past,
you will want try to keep within the boundaries of 6,7,8,9 to
avoid problems (unless you are an expert at troubleshooting).
In linux, you may note that your hard drive is described as hda
or perhaps sda and a number.
If you type at the command line fdisk /dev/hda and then
choose "p" for partition definitions it should describe how your
hard drive is partitioned right now. Press "q" to exit.

I'll assume you do not know about moving and remounting
directories, so we'll go the easy way with more steps but less
chance of problems.

If you have not done anything particularly important on your
Ubuntu worth saving yet and don't mind reinstalling it, I would
recommend putting the /home in a separate partition which you can
share between Ubuntu and Mandriva, and also a separate /swap
partition that can also be shared. If you need to keep certain
things, then make a backup of what you want to keep and put those
aside to restore later. This is better done now before you
install Mandriva. We want to avoid some complicated moves later.

I prefer to backup my machine before causing some major changes
such as these, it is strongly recommended you find a method to
backup your computer at the hard drive "image" level so you can
recover from a disaster if something goes wrong. this may help if
you have another computer available with sufficient hard drive
space. Substitute windows "share" instead of Samba if the other
computer is windows based.
If the above does not work for you, just make sure you make a
backup you can recover from one way or another.

With your Ubuntu install CDrom divide and install your Ubuntu
somewhat like this (partition #s and sizes may vary)
hda1 = C: = XP ntfs (maybe 15 to 40 GB in size)
hda5 = extended partion which holds Ubuntu and swap
hda6 = home = Ubuntu (to share with Mandriva, make it
sufficiently large)
hda7 = = Ubuntu (maybe 4 GB or bigger, does not have home)
hda8 = empty partition (same size as hda7 - not defined)
hda9 = swap (approximately 2x the size of your RAM)

I recommend in the order above since you should rarely if ever
need to use /swap (so it is at the very end of your harddrive),
and your /home is next to your XP C: partition, which allows you
to change and modify everything in between your /home and /swap
without having to modify your XP C: /home or /swap any more.

Next, get your Mandriva CDrom install disk, and begin installing
it, during install, you want to re-use the existing Ubuntu /home
and existing Ubunt /swap partitions, so you indicate during
hda1 = C: = XP ntfs (maybe 15 to 40 GB in size)
hda5 = extended partion which holds Ubuntu and swap
hda6 = home = Mandriva (to share with Ubuntu)
hda7 = leave as undefined (it is your existing Ubuntu ""
hda8 = = Mandriva
hda9 = swap (approximately 2x the size of your RAM)

The values 1,6,7,8,9 may not be the same as they are assigned by
the partitioning tool, but the locations on the disk should be in
that order. Mandriva has resizing and partition moving options if
the partitions need to be re-sized, I think Ubuntu also includes
similar tools too. After finishing, run XP and do a command-line
chkdsk C: to make sure XP is happy with any changes you may have
made to XP's partition.

You should now have XP, Ubuntu and Mandriva with a shared /home
partition and a shared /swap partition. thanks

How to Install both XP and Linux?

I would install XP 1st then Open suse or Ubuntu. When you install either of these linux OS's ensure you install to another partition other than the windows one. Both installation routines will allow you to format the drive to the linux ext2 format and automatically install a boot manager (usually GRUB) which will allow you to select the OS you wish to boot.

Ubuntu Installation

If your able to see the Windows Setup page, and get as far as your partitions, I would suggest deleting the partitions on the hard drive (make sure you know what your doing before trying this), as Ubuntu is mounted normally on a filesystem which Windows can not read (EXT2/3 for Linux - Fat32 / NTFS for Windows).

Once you have deleted all partitions, you can then create a partition (I'd recommend just clicking Install) and then chose the second option to format (not quick) for NTFS.

This then does a "secure" format of your hard drive, setting you up for a nice stable installation.

Apart from that, why don't you try jumping onto for Ubuntu Help, since Ubuntu is a much better Operating System (OS) than Windows, and there is a great community for helping people.

possibly by first creating a new partition large enough for Linux OS, but does not solve your problem...try getting a VISTA startup disc from another pc (floppies if you have the drive) and startup from these.
