Ubuntu Installation :: Partition By Default - How Much Disk Space A Non Manual Dual Boot Uses
Apr 23, 2010
how much disk space a non manual dual boot uses? I've always been guided by a person knowing much about linux when doing my dual boot (and been guided to do the partitions manualy), but this person is not there for the moment and I need to do a dual boot on my son's computer. Since he'll need his Windows computer mainly for games I wouldn't want Ubuntu to take 2/3 of his disk space (which is about 250 Gb I think, let's say 50 Gb would be perfect for the Ubuntu)
And I'm not sure how I could change this later, cause in my own computer I cannot find how to resize (I cannot unmount neither resize the partitions I have) I don't mean I need to do this on my computer but I mean I wouldn't want to try out anything if I'm not sure it be could restored in 1,2,3. And partitions is such a thing. If I remember correctly I've done dual boot by default (i mean without doing the partitions manualy) and it does about 50/50 ?

I installed the live CD version of fedora (dual boot with vista) on my laptop. After I connected to the internet the updates downloaded and all went well. however when i restarted at the boot screen I found two instances of fedora such as
Fedora(2.6.27.9-159.fc10.i686)
Fedora(2.6.27.5-117.fc10.i686)
Other
The "other" is vista. I am wondering if this is OK or whether I have two fedora. If so i would like to remove one of them to save disk space.

I recently made the move from windows to Linux and I am happy to having got rid off all the MS stuff. Trying out a few distros I decided on using Ubuntu and Mandriva (wife likes the flashier stuff, what can I say ).
My question is how can I partition my hard disk in such a way that my /home is separate from both the Ubuntu and Mandriva part but accessed by both as my default home folder.

I have booted from the .iso cd I made on my Mac last night and was tempted to install it on a 6gb partition that I have on my main HDD but was a bit scared to go past the fourth (or so) step in manual installing where I pick that partition and *do what?* Is it going to install the OS on that partition and leave everything else alone to give me a dual booting PowerMac? It doesn't quite say. I am fearful of screwing up my little ol' machine. Can anyone direct me to something that gives a step by step in manual installation on an already created (HFC+) partition to create a dual booting PowerMac?

I'm fairly new to ubuntu. I set up dual boot with 10.4 (64bit) on a machine with windows 7 installed first.Everything worked just fine but it seems that there is a bunch of unallocated space on my hard drive. Can anyone explain what all the different partitions are and if/how I can "clean it up"?

I have a (slightly complicated) dual/multi boot system.
I keep getting boot errors (when choosing ubuntu from the grub2 menu)
Code:
Serious errors were found while checking the disk drive for /boot
If I switch off and restart, ubuntu will then start without issue.
My setup is like this ....3 disks, one with 10.10 clean install - so Grub2, separate partitions for /, /boot and /home, one with windows 7, one with windows XP and 10.04 wubi (this is my old disk which I will trash once I'm happy with my upgrade to 10.10 & 7 on separate disks.
I installed 7 and 10.10 with ONLY their disks installed. After both were working, I added all disks and rejigged the grub2 menu (using update-grub and StartUp-Manager).
This problem only seems to occur if my previous boot was not 10.10 ( I will investigate this further). It's as if something (grub2 ?, the bios ?) is remembering part of the previous boot and not using the grub2 menu completely.

I have a 80GB HDD on which I have installed Ubuntu10.04. I have about 45GB space remaining. I am trying to install Fedora13. I create : 2GB / partition - 2.4GB swap partition. I want to create 6GB /usr partition and it says not enough disk space? Why is it giving that message?

I am quite experienced user of Ubuntu desktop / server distributions. Recently my desktop 9.10 disk failed and I decided to reinstall using 10.04. My configuration is a dual disk dual bot system. I have XP Pro SP3 on one disk and Ubuntu 10.04 on second. XP has own, untached MBR ubuntu got Grub 2 installed on the same disk as Ubuntu. Ubuntu disk is booting first in BIOS. Grub 2 detected both system, however I can boot only to Ubuntu. When I am trying to boot XP I got black screen only. Looks like booting is stack in BIOS stage, because crt+alt+del reset system.
I read Ubuntu forum, search Google and did not come with any solutions. My XP MBR is OK. I can boot directly, choosing XP HDD in BIOS as a starting disk. All entries in grub.cfg looks fine to me. I made 3 different clear installations of Ubuntu. Each with the same result. I reinstaled Grub2 with no effect. I wonder if this may be a hardware/Grub 2 compatibility issue. I am using quite old components.My motherboard is Assus P4C800 Delux. I have 5 HDDs 2 CD. Exactly the same configuration was OK with 9.10/XP dual disk dual boot using Grub legacy.

This is the third 9.10 install to do this on two different laptops, so wondering what's up...
In both cases, the goal was to leave a large chunk of unpartitioned disk after the Ubuntu partitions, for a second OS install or a filesystem Ubuntu cannot create like NTFS.
When I install with manual partitions, the system can't boot and asks for me to insert a system disk and press any key. When I reinstall telling Ubuntu to "use the entire disk" it then works.
First laptop, first try:
Remainder of the 500GB disk is free space.
Fails to boot, "insert system disk".
First laptop, second try without the /boot partition:
Remainder of the 500GB disk is free space.
Fails to boot, "insert system disk".
"use entire disk" works perfectly.
Second laptop, first try:
Same thing, non-system disk or disk error, insert system disk.
Second try "use entire disk" is currently in progress but I expect the same to happen.

I have been having problems hibernating my windows 7 partition recently. It happened approximately right after I set up the dual boot.
I have found other topics where it says to make sure that the windows 7 partition is marked as the active partition. I have since done so and it has not changed anything. I did it with Partition Magic on Windows. I did find it suspicious though that my Dell Recovery partition is labeled as boot while the Windows one is marked as Active and System.
However when I looked at it using disk utility in Ubuntu the windows 7 partition is marked as Bootable while the recovery partition is not.
Hibernation works on Ubuntu with a couple error messages while shutting down and some weird screen issues while booting up. But it ends up working decently.
Under Disk Utility the Ubuntu Partition is not marked as Bootable. Should it be?

Today I was installing a lot of software since I'm just setting up my Slackware system again after a fresh install, and I realized that my root partition has very little space left.
Here is the output of df -h:
Code:
As you can see, I have a 20G (19G here for some reason) root partition, 8G /var, and 86G of /home. I thought this would be plenty since many recent recommendations for / are 10-15G. Now, though, 17G are used up for some reason! How is this possible? I thought a full slackware install only had about 4G of software! I don't have any music or movies or any crazy huge files that I know of, and those would be in my /home directory anyway. Is there any way I can see which files are taking up all this space?
If it's necessary to allocate more space to my / partition, is it still possible to boot up a GParted live Cd, shrink /home a bit, move some partitions to the right, and expand my root partition? I would REALLY prefer I don't have to reinstall since I just spent a ton of time setting up my system again, but if worst comes to worst ... :'-(
In case you're curious, here's my /etc/fstab:

I am attempting to install the 64-bit version of Ubuntu 10.10 on my computer.I'm intending to dual boot Win7 and Ubuntu with one hard drive that came factory partitioned into two drives. Win7 was installed first.Ok, onto the issue. The Install is going well until I get to the Allocate Drive Space form (so almost right off the bat). I first created a swap partition within my "second drive" (really just a partition of the larger drive). This stalled out and I had to exit setup and restart the computer. Booted into Win7 to be safe and Win only recognizes the First Drive and no longer the second drive. So, I boot up the Ubuntu Install CD and get back to the allocate drive space form I see I have a (linux-swap) drive with the same gb space as before.
So, from here I create a partition within the "second drive" 20gb of ext4 type space. This does not stall out and creates a partition of 20 gb. But, now it says I have 175 gb of "Unusable" space. This is very unsettling and using the "revert" button does nothing.How do I fix this space so I can finish the install?[URL]

I had to reinstall my Ubuntu 10.04 system after some trouble trying to remove a FAT32 partition. I reinstalled using the Live Ubuntu CD (not Ubuntu Studio CD) and seems to work fine. I want to know if its normal to have an unallocated space before the boot partition? I installed GRUB2 in the sdb1, not in main sdb. Ubuntu boots fine, but I was wondering if the unallocated space affects it being detected properly by other systems? When I boot OS X I get an error that the HD is not formatted. Previously I was not getting the error. OS X & Ubuntu are each on a separate SATA HD and Windows XP is on a third IDE HD.

I've got Fedora 11 working fine on an HP Mini 2140 netbook. (Wireless works after enabling the rpmfusion repo and installing the broadcom-wl driver.) Now I want to try to put Moblin 2.0 on the netbook as a dual boot.
Unfortunately the Moblin installer (Anaconda? Looks like it.) reports that there's no free space on the / volume. It looks like what's going on is that Fedora 11 created two partitions: /boot and /; and the / partition is LVM and uses all the rest of the available space on the hard drive.
I want to continue using Fedora 11's bootloader for any dual boot. So, basic question #1: Is the solution to create another partition for the Moblin install, or to resize the existing / LV in the existing LV group, and then create another LV for the Moblin install? In other words, can I install another OS on a second LV in the same LVG?

My boot partition doesn't have any space left, rendering me unable to install any updates. Most space in the boot directory (85 MB) is taken by the following files:
initrd.img-2.6.32-24-generic
initrd.img-2.6.32-26-generic
initrd.img-2.6.32-27-generic
initrd.img-2.6.32-28-generic
initrd.img-2.6.32-29-generic
initrd.img-2.6.32-30-generic
It seems to me that I�d need at most one of these. What exactly do (or did) these initial ramdisks do, and is it safe to delete them?

I've installed Windows 7 Ultimate on a notebook which previously ran Vista. No problems there.I've now installed Ubuntu (now updated to 10.04)so that it can boot to either OS.
It all works fine and when I first power up, I get a screen which invites me to select the OS I want to use. There are however two problems:
1) it defaults to Ubuntu (whereas I would prefer it to default to Windows 7 (it's a work laptop and most of the applications are Windows-specific),
2) the list of choices is getting increasingly complex with an expanding list of choices (with each major update of Ubuntu adding more); it even seems to include an option to go back to Vista!As long as I move down the list and make the right selection quite speedily, I get to where I want to be (though, as I say, I would like to change the default option).Is there any way I can edit/shorten this list without damaging the functionality and how can I change that default?

I am thinking about installing Ubuntu dualboot with Windows 7. However, I feel that it'd be a pain to select Windows 7 constantly as it is my main OS for work and school. Ubuntu would be for offtime tinkering and as such probably booted once or twice a week at most. I intend to use the system to use the OS not to use it for serious work. Before I install would it be possible to install it in Dualboot while maintaining the ability to boot W7 by default unless pressing a special key to come to the Grub bootloader or something like that.

I am trying to dual boot Fedora 13 onto my Windows 7 machine. I have shrunk my Windows drive to create 100GB of unpartitioned space, but when trying to install Fedora onto this free space (it is recognized as "Free" space), the installer tells me that there is no space for the partition.

After installing karmic with Grub2 I am unable to boot into Archlinux partition. Grub2 has removed the last line of the Archlinux boot stanza! It used to read:-
[Code]....
Following the Grub2 tutorials I have tried editing /etc/grub.d/40_custom as follows:-
[Code]....
But no luck. Only way into Archlinux is to get into the edit shell and manually add the missing line and remove other stuff not needed. I have spent hours trying to resolve this issue and I am fairly p----d off

I have been running Ubuntu 9.10 and Win XP Professional as a dual boot system, with each OS on its own HDD, smoothly and seamlessly since the release of 9.10. Yesterday one of my kids got a video file from a friend and it had a virus along with it. Long story short, in the process of trying to repair it Windows shuddered it last agonizing breath.
Now I have to re-install Windows because some of the programs the schools make them use require Windows. How do I go about doing this without damaging my Ubuntu installation? Will re-installing on a second drive affect GRUB?

I killed Win XP awhile back, but there are a couple games I need to format for Ubuntu to use, using XP to get there.
I have Ubuntu LTR. I formatted disk to install XP. I installed XP. I can't boot into Ubuntu anymore unless from a live CD. From Live CD, I can see my Ubuntu is still there, but from XP, disk manager it shows that space as empty (free). How can I dual boot, now? Please don't tell me I need to reinstall Ubuntu, I may cry. Any help is appreciated and my apologies if my search didn't get me the answers, the other similar problems I saw were in reverse order (Linux onto drive after XP).

GNU GRUB 0.97
Ubuntu 8.04.4
2.6.24-26
Added an SSD (dev/sdc) and decided to move some less often changed directories there. Started with /usr and /boot, leaving / on a primary in the first drive, for now. All started ok, and my changed fstab mounted the right ones, and the system works.
However, grub is actually using the original /boot on / on sda1. I cannot see any way to change this. (Which makes it sorta hard to update the kernel
From grub:
Okay, since it has two choices, I tried to tell it which one to use. But, grub> root (hd2,5) does nothing.
Disk /dev/sda:
what I seem to recall, grub doesn't care about the boot flag on the disk. Nor does it care about primary vs. logical (except GNU doc says "makeactive" only works on a primary?).
The GNU doc also indicates that it looks for a directory /boot on the partition, so if you're mounting a partition as /boot, it also needs to contain a /boot directory under it. Tried that, but no change.
Is my problem the logical partition? Does that prevent "grub> root" from changing it? I'm afraid to wipe out the old /boot and find that I can't start up.

I was struggling how to phrase the question (in the subject) so let me clarify... I wish to install Windows 2000 and then do Ubuntu, on the same PC. I never had a dual boot before but I understand that it goes automatically (after a short time) to default Windows if Ubuntu is not chosen (on the boot up screen), correct? If so, if there's a "countdown" of sorts, is there a way to disable it? I wish to have control over that aspect, have unlimited time during that boot "choose one" screen.

I am building a new PC from scratch and want to dual boot XP and Ubuntu. I have two 1TB drives. I was planning to run RAID 1, whereby one drive would mirror the other drive, and install XP, Ubuntu, and all data on the single drive. Now Im thinking maybe I should reserve the 1TB drive for data and install two smaller drives, one to hold XP and one to hold Ubuntu and their respective programs. In this latter config, the OS and programs would not be mirrored. Im new to dual booting and linux.

I was impressed to be asked on Fedora 10 if I want to upgrade to Fedora 11 but the first time I tried I had this error:
Not enough space in /boot/upgrade to download install.img.
My boot partition is 99MB and AFAIK that is not unusual so I tried tidying up a bit, uninstalling all except 2 kernels, and now have about 80MB for whatever needs to be downloaded in /boot/upgrade. But I get the same error. I can fix this by using wired instead of wireless networking but I want to know for planning purposes (next time I create a boot partition) how much space is required?
$ ls -l /boot/upgrade
total 21594
-rw-r--r-- 1 root root 18985802 2009-06-03 00:02 initrd.img
-rw-r--r-- 1 root root 3035056 2009-06-03 00:02 vmlinuz
Should I delete these? It looks like they might be left over from last time but I assume preupgrade knows what is junk and what isn't.
