Ubuntu Installation :: Add Extended Partition In GUID Partition Scheme?
May 12, 2011
I am not really sure if the title makes any sense or if it even possible. Basically I am currently triple booting with Mac osx on the first partition windows 7 on the second and ubuntu linux on the 3rd with a swap partition. So basically on my 2TB harddrive
Mac (200gb)
Windows (200gb)
Linux (200gb)
Swap (8gb)
NTFS(1592gb)
The last partition is formatted as ntfs using Gparted, windows cannot detect it. The windows disk partitioner shows the swap and ntfs partitions as unformatted. I can unformat the space and use the windows partition to add format it as ntfs but it would format the linux swap partition as well. I am worried that it could potentially screw up everything on my harddrive. My question is. What do I need to do to get the ntfs parition recognized by windows (should I use the windows partitioner)?

Around 2008 i seem to remember PartEd on the command-line was able to rescue deleted partitions and gave a choice of whether to recover the partition as a Primary or Logical Partition. I have tried testdisk but didn't really grok what i was doing. I successfully moved a "Windows Recovery" partition to the end of my hard-drive, immediately after the drive's Extended Partition.

extended sata partition shrunk at 15 partition limit, how to re-enlarge i hit the 15 partition limit, forgetting it now exists for sata drives, thinking i would add more. upon creation of the 15th, it squished the end of the extended partition to meet the last logical partition, leaving a large unallocated portion after the extended partition, which seemingly nothing can be done with, just sat being wasted space. i have since deleted a few of those partitions, but so far have still failed to find a way to recoup the unallocated space back into the extended partition.

if necessary, i'll do it the painful long winded way of backing up and starting the extended partition again from scratch, but i really rather wouldnt have to do that. i'm sure there must be a way of telling the extended partition to once again reach the end of the drive.

I want to convert a vfat partition into an ext4 partition. This is on my wife's machine and she deleted the Windoze partition as she now prefers Linux. Here is the (edited) output from fdisk -l:-
/dev/sda2 514048 4708351 2097152 83 Linux
/dev/sda3 4708352 6805503 1048576 82 Linux swap
/dev/sda4 52693200 234436544 90871672+ f W95 Ext'd (LBA)
/dev/sda5 59006800 234227699 87610446 83 Linux
I want to change /dev/sda4 to 83 to free up space for Linux without losing the partitions in this 'extended' partition!

I've got a server that needs more space. To achieve this we added space (by extending the VMware disk attached to it).Normally this isn't an issue, because we just add an new partition and LVM it from there, but this host predates our deployment of LVM everywhere.
Our current theory is that the unallocated sectors can not be assigned because they aren't part of the extended partition, and thus ... we go in a circle.So what i believe the way forward is to extend sda4 so that i can then create an sda10 inside of it. Anyone have any ideas on how to do this? I was thinking gparted may do the trick ... but being a server i'm in runlevel3, with no X...

1. Primary or Logical
2. type

A snapshot of my existing partion configuration can be viewed at: [URL] I intend for the space including /dev/sda1,dev/sda2 and /dev/sda3 to be used by slack 13.0. The OS at /dev/sda6 and /dev/sda7 will be "retired" once I get slack up, running and configuration for my work. In the past I have preformatted partitions, that is, from the existing OS, I have formatted partitions for use by the next OS, using gparted. In the case of ubuntu, that has worked well. And frankly, I'm pretty rusty with fdisk....
1)Is there any advantage - or disadvantage - in my doing this for my pending slackware installation? Will slack recognize the "clean" partition and opt to skip formatting?
2)I presume that slack will recognize the existing swap partition. Am I correct?
3)My scheme would be to provide separate partions for /, /home/ and /usr or /usr/local.
4)Any recommendations on filesystems?

I have been attempting to set up a bunch of partitions on a bunch of hard disks, in preparation for installing Maverick. I will be setting up a number of RAID partitions, so I will install from the alternate disk (ubuntu-10.10-alternate-amd64.iso). Now ever since they added support for GRUB2 and a new partition type and align-to-megabyte and a whole bunch of other goodness, partitioning has been buggy. This has been true for Maverick and Lucid. Even the 10.04.1 version (an Ubuntu LTS!) still has problems. Every time I try something else, some other bizarre bug rears its ugly head. (Yes, I have been reporting them on Launchpad when I find a new one.)
In order to move forward on this project, I have been using a variety of partitioning tools. I temporarily installed Maverick on a small partition, and have used Disk Utility (palimpsest) and GParted while booted into that. Occasionally when things get really strange I boot up the latest version of System Rescue Disk, which contains the latest version of gparted. I use these various tools to try out various partitioning schemes, just laying out empty partitions that will be formatted or assembled into RAID arrays later. When I get all the desired partitions set up, I will boot into the alternate installer and do the final installation. (I don't want to do the entire thing within the alternate installer because it makes my head hurt. I do have a lot of partitions.) This has been going on for weeks now. Every time I try something different, something weird happens, and I have to try various workarounds, or switch to different tools. Basically, my partitions eventually become unstable.
Here's the latest mind boggler: Disk Utility displays nice graphical maps of your partitions. This image includes before and after screenshots showing what happens to my partitions occasionally. We start with three primary partitions and one extended partition. The extended partition goes all the way to the end of the disk. We put a small logical partition into the extended partition, at the beginning of it. We can then click on the "free" portion of the extended partition and create additional logical partitions if we like.
Afterwards, the extended partition has magically shrunk itself down until it is the same size as the small logical partition it contains. The free space has migrated out of the extended partition, and is now useless, as you can't have more than four primary+extended partitions. Disk Utility won't let you create another partition. What happened between the Before and After pictures? I don't know. I do know that I did not ever tell any tool to change the size of any partition. Moving or resizing partitions can trigger various known bugs, so I never even try to do that, I just delete partitions and start over.

I've installed Windows 7 + XP + Ubuntu 10.10 and Mac Os X on my PC. The problem is that XP wont boot. I've tried a lot of fixes for the last 2 days but still nothing. So I've come to conclusion that it might be probably due to its partition (dev/sda being inside of another Extended partition (dev/sda3) as you guys can see on the attachment. If so, how can I move it out of the extended partition.

3. /dev/sda3 = linux-swap (2000mb)
4. /dev/sda4 = extended (7000mb)
5. /dev/sda5 = /home (7000mb)

just got a new laptop with Windows 7 Home Premium 64bit pre-installed, and when I boot into my 11.04 CD, there is no simple option to install alongside windows 7. Only the options to erase the entire disk (wiping windows) or manually specifying partitions. I'd like to keep my windows install as I use it for gaming, but I don't want to mess around with partitions while I don't know what I'm doing. According to the 'Allocate disk space' part of the installation, all 4 primary partitions are being used, a main one for the Windows 7 install, one entitled HP tools, and another two I forget the names of. I have looked up that I may need to turn a primary partition into an extended one,

I recently installed Jaunty in my departmental machine which is having 70 GB harddisk and 512 MB RAM. Before installing I partitioned the Hard disk by using Gparted of Live CD into Four compartments namely
1. Primary partition of 30 GB of file type ext3
2. Extended partition of 39 GB which I divided again into two logical Partition of 20 GB and 19 GB. Labelled it as D and E
3. 1 GB of swap partition
I installed the Jaunty in primary partition, gave the mount point as /The problem is I am not able to copy or save file in the extended partition namely D and E

I bought a PC with Window Vista on it as my partner needs it. Using gparted I set up Primary partitions for Vista OS (sda1) and Ubuntu OS (sda2), plus an extended partition for Vista files, Ubuntu /home and swap:
fdisk -l
Device Boot Start End Blocks Id System
/dev/sda1 * 1 3969 31880961 7 HPFS/NTFS
/dev/sda2 3970 5294 10643062+ 83 Linux
[code]...
My problem is Vista (as always). The 30GB I allocated is not enough, even just for the OS and it won't now boot from GRUB, though I can see it from GRUB. I don't want to do anything that risks a problem for Ubuntu. Will grub still see both OS if I wipe sda1 (Vista OS) and reinstall Vista OS on the extended partition sda6? Ideally I would like to merge sda1 with sda6 and install Vista on that, but that looks way too risky / impossible.
Edit - There is another drive on the PC which is much larger and I use for backup. Is there any scope for installing Vista on that one so that GRUB still identifies both. Not ideal as I like having one as the backup for the other.

I successfully partitioned my desktop with Gparted and made it into an XP/Ubuntu dual boot.
Now i'm trying to do the same with my netbook (eee pc 1000he), and the existing partitions look funny:
How should I change this to prepare for installing Ubuntu? Can I just install to the unallocated space on the extended partition? I don't need optimal efficiency here, I just need to know where to install Ubuntu for a workable dual boot.
It's confusing to me that Windows is on an extended partition, and also that /dev/sda2 has the boot flag (this drive contains nothing but two undeletable folders titled "amd 64" and "i386"). This set-up is the result of a Windows re-install at a sketchy computer shop.

I have installed Ubuntu 10.04 LTS on machine but wanted to choose RAID and LVM during partition scheme. Unfortunately I couldn't find such option during partitioning. Is it true that for Ubuntu 10.04 LTS it is unable to use RAID and LVM ?

I setup a dual boot system, with approximately 200gig planned for ubuntu 10.10. Based on the article here:[URL]..And this quote:
Quote:
# sda1 Recovery Partition, unchanged
# sda2 Windows partition, shrunk preferably from inside Windows, hopefully about 30Gb
# sda3 Primary Partition, 10Gb, file-system = ext3, in the Partitioning Section of the installer change the "Mount Point" = /
[Code]...
I assumed at that point that the "sda3" "/" would be for booting purposes. I would have to guess that I was wrong, because it is filling up very quickly. As you may be able to tell by the screen shot, "sda5", "/home" was what was assumed to be the file structure to store all of the programs and such.
I have only been running this setup for a week, and would expect to not be seeing my "boot" partition growing so quickly. Do I need to resize it? here do the standard programs that I get from the ubuntu software center install at (partition wise)? I suppose I dont mind wiping that section dry and starting over, but I would give a resize a try if possible.

I'm installing Centos 5.5 on a HP ProLiant DL180 Server with ~8 TB of hard disk (4 disks that have been pre-RAIDED), from an installation DVD.
Normally when I get to the partitions screen, I would select "remove all partitions etc".
But this gives me an error message "Your boot partition is on a disk using the GPT partition scheme but this machine cannot boot using GPT. This can happen if there is not enough space on your drives for the installation."
Pressed OK, tried the other three partition options but they led to the same outcome.
Tried Advanced storage configuration: Showed that there was one hard drive (c0d0) with ~ 8 TB of space.
I figured I should create a root sector, set one up with 100 MB of space, ext3, set the mount point as /.
Created a software raid of the remaining space.
Trying to go "next" gave me a similar error about GPT partition scheme. Trying various other configurations all gave similar errors about the GPT scheme.
What do I need to do? Some earlier hard format of the disk or something?

i was experiencing slow start ups since i installed ubuntu 11.04. it took about 20-30sec for the apple logo to come up (or rEFIt). today apple released EFI firmware updates which doesn't seem to install. reason is that the partition scheme is not compatible. EFI Firmware updates only install from GUID partition schemes.
DiskUtility tells me i have MBR. So it seems like Ubuntu changed the Partition Scheme.
Can any body confirm that? how can i make sure ubuntu installs into existing GUID? i will re-partition later today and give you an update if the EFI firmware update installs and boot time is faster.

I've got a windows partition with a lot of free space followed by an extended partition. The extended partition has three sub-partitions: grub/boot&everything else, home, swap.
I'd like to take some of the free space out of the NTFS partition and move it down into the extended partition for Ubuntu to use.
I've successfully shrunken the NTFS partition. Now I've got 5gb of unallocated space between the end of NTFS an start of the extended partitions.
Now I want to extend the boot/everything else sub-partition within the extended sub-partition.
Using the gParted live CD I'm:Resizing the extended partition (growing it forward by 5gb)
Resizing the boot/everything sub-partition forward by 5b
When I try to apply the changes I get an error: Unable to satisfy all constraints on the partition.
Is it possible to move this space into my extended partitions so Ubuntu has more space?

I somehow messed up my filesystem. I installed Ubuntu directly with LVM. This created an extended partition including a logical one. When I run out of space, I just increased my space (through VMware) and then added a new PRIMARY partition.
Then I added this one to the volumegroup and increased the logical volume. After I did this a few times, there were no longer any primary partitions allowed (only 4). Then I resized the FS, resized the logical volume, resized the volume group, and removed the physical volume. Now I'm no longer able to create an extended volume (only one) but it's not at the end (there are other primary partitions behind this one at the disk), so I'm not able to create some logical volumes.
What is the best possibility to add some space to the LVM and being able to do this a few times in the future again?
further info:
pvscan:
fdisk -l for sda:
There was a /dev/sda3 at the end of the disk. I already deleted this partition.
So the order on the disk is: sda1 | sda2 (extended) | sda5 (logical referred in sda2) | sda4 | free space
Does it matter that there is type "Linux" for sda4 or can I without damaging the lvm just change it (with cfdisk) to "Linux LVM"?

Two days ago I want to expand the free room for my C: partition on my laptop, i thought that just shrink the D: partition and expand the C: and the problem solved, but it's not solved, the C: remains and can't be expanded. so i merge the D: again,but the D: status become an extended partition
After all, next morning I boot into Ubuntu and my D: are not available in "Places" menu in Ubuntu just the C: partition, so I boot from Win7 and run CHKDSK /f to my D: partition, but it's gave me no effects
Code:
sudo fdisk -l
in terminal and my D: listed as "Extended" in System type.
In my Win7, everything is alright

I recently decided to resize a partition on my HDD (partition on which Ubuntu was previously installed).This was in order to remove Ubuntu from one of my HDD. I got rid of the Grub loader by booting on my windows system recovery disk and using Bootrec.exe/FixMbr and my computer now boots directly into windows. I then deleted the Ubuntu partition.
To get to the heart of the problem, I am trying to move the free space that is in the extended partition out and merge it with C. I tried doing this with my Gparted liveCD but it didn't work. I didnt have anything to save the error message onto, but I will try the process again when I get home and save the error onto my external drive so that I can post it here.
