Ubuntu Installation :: Multiple Grubs And Partitions Of Same HDD?
Mar 3, 2011
I searched through with several different terms and couldn't find it.I recently got a DELL Inspiron B120 laptop that had Windows 2000 on it as its sole OS. I'm refurbishing it to some degree. It needs a new LCD Screen and a Wireless Lan card; but that's not important here, I don't think.I'm running it headless and connecting to my desktop through X11VNC.
I decided to put the live disk Ubuntu 10.04 on it and see if I liked it. I decided yes, and went for the install.
Before it installed, it asked me how I wanted to partition the drive. It showed me examples, and I decided to keep the Windows 2000 on there, along with the little DELL diagnostics, etc. part and divide the 40GB drive up into pieces: 18GB for Win2k, 4GB for Dell, and 18GB for Ubuntu 10.04.Once installed I wanted to change the timeout for the GRUB to longer than 3 seconds before it boots the top choice (which is Ubuntu).
I noticed when I could catch it; that it was titled GNU Grub 1.98. I'm not really familiar with multiple GRUBs, so I didn't think about it. Then after a few days, I started getting updates for Ubuntu. The first one was the Ubuntu 10.04.2 LTS, kernel 2.6.32-28-generic from the original kernel 2.6.32-24-generic. Then it went to kernel 2.6.32-29-generic, and yesterday to kernel 2.6.32-30-generic.
That's fine; but the GRUB list is still saying 2.6.32-28-generic as the most recent. Also, the last update asked me if I wanted to create a menu.lst file.I thought I had a GRUB.cfg file that had the list of boots...But I answered yes anyway, and installed the GRUB menu.lst. I changed the timeout to 15 seconds in menu.lst; but the list is still showing as the GNU Grub 1.98 and the list of boots is still topped with 2.6.32-28-generic.I have no idea what's going on now; nor how to update it so that I use the GRUB with the menu.lst and delete or suspend the GNU Grub 1.98.

I installed Ubuntu recently and decided I didn't like it so I went back to Debian. One problem is I now have 2 Grubs installed. One is Ubuntu's that comes up first and then the Debian Grub. To bypass the Ubuntu one I hit F9 (I have an HP computer) which takes me to OS selection. Debian is the only OS installed but the Ubuntu Grub still lingers. This person had a similar problem: [URL] ....., but didn't receive info to get rid of Ubuntu's Grub....

After trying to use Wibu, I gave up and installed Ubuntu separately. But I still have one version of grub from Wibu, and another version from my separate Ubuntu install. How can I get rid of the now redundant second, Wibu grub?
Here is my boot info summary:
Code:
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #5 for (,msdos5)/grub.

I created a customized Lucid image and installed on my computer which has 1 hard drive (/dev/sda)When I booted up .. it gave me an error indicating "Multiple active partitions" ... and did not boot up ...
I used my live CD and run as live session to check on the hard drive, When I issued the command fdisk -l on an terminal , the out put indicated that only /dev/sda1 is bootable, and other /dev/sda* were not bootable ...
I am not sure why I got the "Multiple active partitions" message at boot up time ..

I have used GParted several times but I only know how to clone a single partition. I am looking for a way to clone and entire drive that has several partitions, along withthe MRB, unpartitioned space and everything else in one step. I have a 500 GB drive that is going out and I want to clone it to a 1 TB drive so I don't have to reinstall 3 different OSs and fix the GRUB. One of the other OSs is on anther drive so I'm not sure that it would work even if I can clone everything exactly. I'm not sure if the drive that is failing is the one with the MBR on it or not. how to do this in GParted or know another good program I can run from a live CD to do this?

long time reader, first time poster i appear to have both grubs installed under /boot/grub i have both a menu.lst and a grub.cfg im booting fine, can update-grub fine, my only issue is that i can't remove old kernels and update the correct grub my menu.lst doesn't show the old kernel so i can only assume im booting with grub2 but can only update-grub for grub(1)
it's a minor issue now but i'm worried it will have wider consequences in time

For two of my partitions on sda (they are NTFS parts) I have configured them via the NTFS Configuration Tool to mount at boot. This is OK - I can see them in Places, Computer; they are listed together with the mounted icon to the right. However, there is also two other partitions listed - that are not shown as mounted - with the same label name. (I can also see these duplicate parts listed if I click on Places ad look down at the various devices attached under Computer). If I right click on these unmounted parts I see there is a greyed out option to Remove. How do I remove these duplicate partitions?

I used Ubuntu before, without problems but since the 10.04 version it won't recognize my partitions. I formated my laptop and partitioned it, installed Windows 7 64bit, which I need for my work, and wanted now to install Ubuntu 10.04/10. I then used GParted to check my Harddisk and it is having troubles to recognize my partitions, too while Windows finds them. GParted is giving me an error message saying my partitions are oversized. I am still in the beginning of my Linux experiences and so I don't know what to do. I have two 250GB harddisks (how Windows recognizes them),

Xubuntu 9.04 installation CD not detecting any of the current partitions. This all started when I reinstalled windows XP a few days ago.After, the computer wouldn't boot into GRUB and would boot directly into windows.Other threads have dealt with a similar issue, that of overlapping partitions causing libparted/parted/gparted to detect the whole drive as unallocated space. The problem in these threads seemed to be a corrupted partition table, in which the partitions overlapped with each other. So of course I checked the output of fdisk -l for overlapping partitions, but I don't see any obvious overlapping partitions. I've noticed that the partition that used to be linux swap isn't showing up in the partition table at all. I might just be missing something simple here and would like another set of eyes to help me figure this one out. Does the problem have anything to do with the partition table being out of order (ie. not in order of what regions they cover on the drive)? From the liveCD I've run
Code:
sudo fdisk -lu
sudo sfdisk -d
sudo parted /dev/sda print
and have received the following output:
Code:
ubuntu@ubuntu:/mnt$ sudo fdisk -lu
omitting empty partition (5)
Disk /dev/sda: 60.0 GB, 60011642880 bytes

I am installing Ubuntu on the same hard drive as Windows 7. The partitions of Windows 7 have already occupied the left part of the hard drive. From left to right, the Windows partitions are one partition for Windows booting, one for Windows OS and software installation, and one for data which is planned to mount on Ubuntu. I was wondering how to arrange the order of partitions of root, home and swap, i.e. which is on the left just besides one Windows partition, which is in the middle and which is on the far right?

How do I divide my hard drive into multiple OS'es/partitions for my test machine? For example:
Win XP
Win 7
Gentoo
Ubuntu
Storage
Can Linux'es share swap area? I was told to leave the first primary for the grub and linux cores.

Say I have an image of a file system. I made it with dd by copying it off my USB stick. e.g. "sudo dd if=/dev/sdb1 of=./image.ext2" I can mount said image with the command: "sudo mount -t ext2 -o loop ./image.ext2 /mnt/" Now, say instead of copying a partition with dd, I copy a whole drive. e.g. "sudo dd if=/dev/sdb of=./image.img". sdb had 2 partitions on it. How can I mount those separate partitions without copying that image back onto the USB drive?

Regularly I find myself cloning a machine using rsync. I find it understandable, reliable and fast, faster than dd, and I don't have to worry about different partition sizes etc. However, usually I partition my hard disk in a number of partitions:
Code:
/
/home
/usr
/var
When I start with a new, empty machine, I start up with a USB stick or live CD, and my new, empty hard disk becomes /dev/sdb. After creating the 4 partitions I have /dev/sdb1, /dev/sdb2... etc. My root directory is on the disk I used for booting, usually /dev/sda. So, in order to access my newly created partitions, I mount them on the /mnt/directory of my root:
Code:
mounted now later
/mnt/sdb1 /
/mnt/sdb2 /home
/mnt/sdb3 /usr
/mnt/sdb4 /var
In other words, I mount now /dev/sdb1 on /mnt/sdb1, while after copying /dev/sdb1 will become my root directory, /dev/sdb2 become my /home directory, etc. When I start the resync process to copy the image from a remote machine, I have to copy all 4 partitions separately. First the root directory, excluding /home, /usr, /var, then /home, then /usr, /var, like this:
Code:
action 1:
rsync --exclude='/home' --exclude='/var' --exclude='/usr' my.remote.machine:/ /dev/sdb1/
action 2:
rsync my.remote.machine:/home /dev/sdb2/
action 3:
rsync my.remote.machine:/usr /dev/sdb3/
action 4:
rsync my.remote.machine:/var /dev/sdb4/
That is a lot of typing and waiting. Sometimes I have a different partition scheme so it is not really feasible to write a script to use always. Now the Question: is there a smarter way of mounting the newly formatted disk (/dev/sdb1, /dev/sdb2... etc) in my root tree so I can perform the rsync copy in just one time, without all the excludes, but assuring that the correct source partitions end up on the correct destination partitions?

Say I have this computer and this computer has a 1TB hard disk. I install Fedora 13 on this disk and let the installer do as it wishes with this 1TB of space. I'm going to end up with the LVM thingy. (Can you tell yet that I know nothing about LVM?). Can I, at a later date, use some of the available space to create another partition to install another OS on. Can I create multiple partitions to install several other OS's on?

I did this with :
Code:
I made two partitions as below
Code:
3. Partition Compact Flash
Make two partitions on CF (use linux fdisk or anything else that is able to make linux filesystem)
1. at least 8MB FAT
2. rest ext2 (recommended) or ext3 - at least 50MB
Copy vmlinuz, initrd, linexec and params.txt to FAT partition.
Uncompress rootfs.tar.bz2 to ext2 partition. (command details at ref. [1])
But :
fdisk -l says only one /dev/sdd1
not sdd1a
not sdd1a
How can I mount those 2 created partitions, since they are hidden under /dev/sdd1 ?
Is it a bug of the kernel?

I need to set up a RAID 1 array on Squeeze. I have 3 partitions: sda1 is root, sda5 is home, and sda6 is swap. (sda2 is the extended partition containing home and swap. This was a clean installation, so I don't know what happened to sda3 and sda4...)
All the information that I've been able to find recommends doing something like this:
mdadm --create --verbose /dev/md0 --level=mirror --raid-devices=2 /dev/sdb1 /dev/sdc1
Do I need to type a separate command for each partition, or is there a better way to do it? Also, should I use the UUID instead of the dev names?

I am rebuilding a bunch of servers and want to do it right. They are Dell R200s and R300s with on-board LSI SAS1068E SCSI controllers with 2 SATA drives. The only RAID level supported on these cards is RAID 1. So, to the server, we have 148GB of space to deal with. They currently run 32-bit Ubuntu 8.10; I will be installing x64 Ubuntu 10.04.
I have always seen that it is best practice to partition in such a way that /boot, /var/log, /temp, and /home for example are separated out from /. Usually this is on a RAID5 or higher box. Is there any benefit to doing that sort of thing on a RAID1 box? I realize that this is in some ways a matter of opinion, but I would like the opinion of folks with experience. I'm pretty new to Linux in general.
The main services running on these boxes are Apache2, Tomcat6, MySQL, and Java.

Entries from fstab:
Code: Select allUUID=04E2891117C6D1E8 /mnt/Movies auto user,nosuid,nodev,nofail,x-gvfs-show 0 0

The only one that shows in PCMANFM is the Movies partition. All others listed here are missing.
I checked syslog and it looks like they all mount correctly.
This puzzles me since all of them have the same options set.

My partition layout is as follows:
sda1: 14GB / ext4
sda2: 10GB /iso ext4
sda3: 4GB /home ext4
sda4: 86GB Extended
sad5: 2GB swap
I have 84GB free space on this hard drive and want to install another distro. Will I be able to create another / and /home partitions for the new distro?

I've looked high and low but I haven't been able to find any example of what I'm currently experiencing with my hard disks.First off, I'm running CentOS as a Samba file server, on a Soltek SL-K8TPro-939 and AMD 64 3200+ (all the rage of five years ago). Here's my disk setup
Drive #1 (80 GB)
-Boot partition
-LVM partition (this drive holds the root filesystem[code]....
Ok, so I get a notification in my system mail yesterday: The following warning/error was logged by the smartd daemon:
Device: /dev/sda, unable to open device
For details see host's SYSLOG (default: /var/log/messages).You can also use the smartctl utility for further investigation.No additional email messages about this problem will be sent.

By fiat I must distribute my homedirs across multiple physical disks/partitions. Unfortunately this is not open to discussion so obvious solutions like a lvm home partition are not available to me. The issue: Users created with homedirs on the main home partition (the one created as home during the f13 install) behave as expected, but if I create them on a different partition (home9 for the sake of this example) the users are not able to login (dropped back to login screen), nor run x-apps if su -'d to in a konsole.
If I 'su - <user-on-home9>' in a konsole, I get delivered to the /home9/<user-on-home9> as expected, but x-apps fail with the error: 'cannot open display: :0'. This can be temporarily fixed with the command 'xhost +SI:localhost:<user-on-home9>', but I would rather fix it permanently at the source.
This appears to be an selinux problem from the following.The contexts of the the two rootdirs are the same
% ls -Zd /home /home9
drwxr-xr-x. root root system_u:object_r:home_root_t:s0 /home
drwxr-xr-x. root root system_u:object_r:home_root_t:s0 /home9
but when I create the users (using useradd or the gui) their respective contexts differ:
% ls -Zd /home/user5 /home9/user6
[Code]...
So, my questions for you selinux experts are 1) is it possible to have homedirs spread across multiple partitions with selinux, and if so, how, 2) Why, even when I manually set the dir/file contexts to match a properly functioning user5 from /home, do users from /home9 still not work (as far as login and x-apps).

How would one go about it? Follow the GNOME Ubuntu tips, the ones for Kubuntu, or both? Or would it be easier to just roll back to a GRUB that uses GDM's splash and login and see if the settings I've already attempted are really working (and it's just the KDE stuff that's blocking them).

I installed 4 encrypted partitions (/, /var, /tmp, and swap) that are mounted at boot using the Alternate Installation Disc, and they all have the same password, but I have to type that password in 4 times when booting up. How do I make it so I only need to type in my password once?

I've just installed Ubuntu 10.04.
I'd like to boot using Windows 7 boot manager (I don't dare to put grub in the MBR).
I've used EasyBCD to add a new entry for Ubuntu.
[url]
Then I added Grub to /dev/sda3
And I get this:
[url]
The problem is that it always shows (hd0,0) instead of (hd0,2). I must change it every time I boot. I've tried to install grub again but I always get the same.
And another problem. After that Grub menu it deesn't load Linux but it loads a second grub menu [url] that loads Linux properly.
I guess I've installed two Grubs.
How can I remove the first Grub menu (Grub4dos) and make Windows 7 load the second (the good one)? or how can I remove the second one and change (hd0,0) to (hd0,2) in the second?

Please bear with me as I'm incredibly new to Linux and shell scripting and all that good stuff. This will be a fairly lengthy post, as I don't really know which information is pertinent to the problem at hand and which is irrelevant. I installed Ubuntu on my Macbook following the instructions on this page: [URL].. At step 7, /dev/sda3 was not in the dropdown menu of options, so I picked...I can't remember. Either /dev/sda or /dev/sda2. I think this may be the beginning of the root of my problems. Step 8 is where it all falls apart. I get the following error message: "Status: MBR partition table is invalid, partitions overlap. Status: GPT partition of type 'Unknown' found, will not touch this disk."
Sooo since I can't sync the partitions, I can't get Linux to load unless I'm loading it from the LiveCD. I've tried steps 1-10 on this page:[URL].. However, under step 4, I could either "Save" the file randomly, without actually saving it to /mnt/root, or I could just open it and run the installer. I think I went into FF preferences and changed it to let me pick where each download would be saved, but when I actually clicked on the download link and then "Save", after finding the folder and clicking the final button (Which I think actually said "Open" instead of "Save"), nothing happened. I tried running the rest of the steps after just opening the installer on its own, but of course just got error messages. I hate not being able to troubleshoot this on my own!

The instaler doesnt find my partitions and the XP that is installed too! For some reasons i cannot delete the whole hdd... if i format the partition, where (i want to install ubuntu) with fat, the pc crashes during the installing process after the tastaturlayout question! if i try some other formats, the installer tells me, that there are no Operating Systems installed and the hdd is unpartitioned!
if i start ubuntu live from the cd, the system finds all partitions, but if i run cfdisk in a terminal, i get a fatal error (cannot open disk space)... My machine is a acer aspire 1694 WLMi (pretty old, but should be no problem), bios is up to date, Windows is XP home edition with SP3.

After a fresh install of 7.7.0 (amd64), I'm unable to boot into Debian. I get the following error constantly when booting in recovery mode:
(snip) [drm] nouveau (snip) PMC - unhandled INTR 0x44000000
A bit of Googling seems to indicate that this is due to my video card (Geforce GTX 750Ti). Unfortunately, my motherboard doesn't have any monitor ports, so I'm forced to use a video card in order to use a monitor. Something I didn't foresee being an issue, but what can you do. How should I resolve this? Is there an ISO that has the (presumably non-free) drivers included? A way I can add the drivers during boot (I am able to boot into my Windows partition by changing the boot order, don't know if I can do anything useful from here)? Or do I have to do something crazy like buy/borrow an older video card just so I can properly boot into Debian, and then install the drivers?
I've got a secondary problem: GRUB has my Debian install as the only option, even though I had Windows 8.1 installed first. I don't know if this is related to the problem above, or it's a known problem with newer versions of Debian and/or Windows (and I have to update the menu.lst or whatever myself), or if it's due to the way I set up partitions. My current setup is:
SSD:
- Windows boot partition
- Windows main partition
- Debian / partition
- Debian swap partition
HDD:
- Debian EFI partition
- Debian /home partition
- Unallocated space (will eventually be a NTFS partition for shared storage)
This is the first time I'm using a motherboard with EFI/UEFI. It's also the first time I have an OS taking up partitions on multiple physical devices. I don't know if either is the cause of GRUB not detecting Windows.

I've installed Arch Linux onto my Western Digital SATA drive.I love it, best ever, however, I need the fglrx proprietry driver for better 3-d performace, and decided to create a new partition. I decided to install Linux Mint.Sadly, in all my noobishness, I forgot about the 4 primary partition limit (oops!) and as I have /, /home, swap, and /boot partitions (all primary) already installed, I have run into a bit of a problem.I resized my /home partition (almost 500GB) to about 225, and was then told I have over 200GB unusable space. Is it possible for me to change at least 1 of my primary partitions to logical partitions AND keep all the data intact (AND edit the arch configuration so that it'll still work) so I can install a second linux? I sincerely doubt it
