Ubuntu Installation :: Separate Boot Partition - Doesn't Care About The Boot Flag On The Disk
Feb 14, 2010
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.
While installing with a separate /boot partition I cannot get two distinct copies of ubu installed on one machine and be able to choose between them. Each is installed on a different hard drive. x64 versions. I've had this issue both ways:
Stepsinstall mythbuntu install ubuntu Result
Two entries in grub. Both cause ubuntu to boot
Stepsinstall ubuntu install mythbuntu Result
Two entries in grub. Both cause mythbuntu to boot Grub 2 is so unfriendly for fixing these things. I don't know where to make changes. Ok, Grub 2 is very powerful, maybe it's the lagging documentation, or lack of tutorials that is the problem. But I don't know how to fix this. Do I start over without the /boot partition? Do I bail on ubu?
I have a 320gb USB hard drive, one partition for my files, one for playing Wii games, and one which I would like to use for an Ubuntu instillation.
To do this, I partitioned my disk accordingly using Windows, then booted from the Ubuntu CD to install the OS to my external hard drive partition. It asked me where I wanted to install the boot loader, so I selected the hard drive itself, rather than the specific partition, reasoning that it would scan the hard drive for a boot record.
However, when I booted it (with USB boot selected) it simply said "No Operating System found, replace system disk and press enter" or something similar.

Trying to dual-boot OpenSolaris and FC10 is difficult because Solaris grub doesn't know about ext3 and Fedora grub doesn't know about ZFS. I was able to rescue my FC10 installation by creating a new FAT16 partition and restoring /boot to it from a dump, and then doing a grub setup to it. A complication is that anaconda doesn't seem to be able to find /dev/md0 (both the Solaris and FC10 installs use mirrored disks).
This process moved the FC10 ext3 partition from /dev/sda3 to /dev/sda4, but the other half of the mirror is still /dev/sdb3.
When I boot FC10 I get a "can't load image" error from grub, but it still loads FC10 successfully. It makes no difference if menu.1st/grub.conf has "root (hd0,1)" (the FAT16 partition) or "root (hd0,3)" (the FC10 ext3 partition).
If a future yum update were to try to install a new kernel, my FAT16 partition would not be updated. It seems to me both these problems might be solved if I could move /boot from /dev/md0 to /dev/sda2 (/dev/sda2 is the FAT16 partition).
Rather than go through yet another install, would the following work?
from FC10, move /boot to (say) /boot.0 mkdir /boot edit fstab to include "mount /dev/sda2 /boot"
If I try this and it doesn't work, I can't see any way to undo it since anaconda doesn't seem to be able to mount /dev/md0. If a grub guru sees this, perhaps they could suggest a better alternative, or if not, whether this will work or not.
Additionally, although there are two alternatives in menu.1st/grub.conf, grub doesn't display a menu - it goes directly to boot. Any idea why? I suppose this might be a Solaris stage1 grub problem...
Since FAT16 doesn't support links, it isn't possible to link grub.conf to menu.1st. Are they both required?
Everything works fine, the setup went very well. But I got to thinking (A dangerous thing for me). In Ubuntu I am using separate partitions for / (root) and /home. I was wondering, during install of Fedora, could I use the separate partition I am using now for both root and /home for just / (root) and use the Ubuntu /home partition for Fedora (set the mount point for /home to the same partition as I did for Ubuntu and not format the drive)? This would allow me to seamlessly use the /home partition and not require duplication of files. I can mount the Ubuntu /home dir while in Fedora.I can share the /home partition with two different installs of Ubuntu (been there).
Caused by Used fdisk to delete the windows partition, in my dual boot. Then I could no longer log in to ubuntu, the partition table was some how courpt and I couldnt remount I then decided to use the windows partitioner from windows setup, as I thought it is so stupid, to reformat the partition where I had ubuntu. I wanted reinstall ubuntu, and I know that during the setup I could straighten out the mess I'd made.
Windows has now installed two 8mb one cylinder partitions on my HD. When I start the PC I get a !disk error occurred Press Crlt Alt Del to restart! This happens everytime. HD boot sequence is buggered, i guess.
I can boot from other devices. USB + CD. How when I use the windows disk to boot up I can see the 2 8mb partition, which it wont let me delete. How can I delete this via linux?
Also when I try to install ubuntu from the usb drive, it stalls just after the Preparing to install part. The next screen is when you set the partition table, swap drive etc. When I quit I get the following error !Process Glib WARNING getpuuid_r() failed due to unknown id!
The usb_liveCD does however mount my hard disk partitions and luckily I have managed to back everything up to an external.

Noobish question on multibooting multiple Linux distros. I have four of the current major Linux distributions. Each has been installed and run individually (no other Linux distribution installed) in a dual-boot configuration with Windoze. No problem.
What I want to do is install all four Linux distributions and multiboot them. Reading the internet it would seem this is a simple task with GRUB. The short version being - install a Linux distro with a separate /boot partition for GRUB and use GRUB to boot the other Linux distros from the GRUB boot menu.
So I installed one of the Linux distros with a separate partition for /boot. The distro installer installed GRUB in /boot and correctly setup a dual-boot configuration with Windoze. GRUB was installed to the MBR. Next I installed a second Linux distro in its own root partition and told the distros installer NOT to install GRUB to the MBR, but rather, to the boot sector of the root partion of the second Linux distro. Installation was uneventful (and I could access the second Linux partition from the first installed Linux distro, things looked ok). Then I added to following to the installed (MBR - /boot) GRUB's menu.lst:
Code: title lixux distro 2 root (hd0,7)
chainloader +1 After which I rebooted the system and the new entry for the second Linux distro now appears in the GRUB boot menu. I selected the second Linux distro from the boot menu and got the following GRUB error: Error 5 : Partition table invalid or corrupt [Code]....
I just installed windows 7 and ubuntu stopped booting even though it was still there, so I thought I would just change the partition flag to boot. I found out later that I had to create a new mbr but after I changed the boot flag, windows 7 stopped booting and I tried changing it back, but it didnt work. So I was wondering if i didn't use the correct flags or is there another way to get windows 7 to boot again? I was using GParted to change the partition flags and that i am using windows 7 ultimate 64bit
install fedora 11 on Vista I want to keep the windows boot loader and also install on a usb drive or a seperate partition that has 10GB free "install doesn't see partition's". Recently I installed ubuntu and had a major problem with booting, without having the usb drive connected I couldn't boot windows so uninstalled it. I'm trying to install now but install does'nt give me any option to select partitions from my drives one 320GB "portable, 3 partitions" and 80GB "main os 2 partitions one partition has 10GB free"
is their a boot partiton that need to be kept seperate in ubuntu? Screenshot.png those are my partitons in the pic above am i okay to merge them all into the dev/sda2 or is it like windows and i need to keep a small section back for the boot?
My laptop had 1 hard disk, partitioned as follows:C: (NTFS), on which Windows XP was installed.D: (NTFS), on which I stored my personal data.Recently, I bought a new hard disk, and divided it into two partitions: An NTFS partition (to store personal data), and another partition on which I installed Linux (Debian Lenny).I want my systo act as follows:While booting the system: if I select to boot from the first hard disk, Windows XP loads. Else, if I select to boot from the second hard disk, Linux loads.In other words, I want the MBR of each disk to point at the corresponding OS.
I have been working in my spare time over the last few days, Had problems with the whole grub2 not installing on RAID 1. Then I found out that I had to have a separate non raid Ext4 partition on one drive with "/Boot" as mount point and install went though fine.
My question is, will the developers FIX this. I mean if I only have 2 x 2tb drives in teh pc as RAID 1, and the one fails with the boot partition the whole machine goes down. Kinda defeats the whole RAID feature huh.
I USED to run a windows network with RAID 5 servers, and windows never had a problem installing everything on the RAID. Or even setting up RAID 1 in the bios on the PC and installing XP or NT4 on the RAID 1. There was never a need for a separate non raid boot partition.
Do we need a separate RAID friendly/enabled Grub? I guess for now I will get a 250gb drive and install the Server OS to it, and setup RAID1 manually after the server OS boots. Then will make a ghost type image of the server in case that drive fails so I can quickly install a new drive and restore the image and get it back up and running again.
I meet a problem about "Your boot partition is on a disk using the GPT partitioning Scheme but this machines cannot boot using GPT." in installation. Does GRUB-0.97 on CentOS 5.4 support GPT?
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.
P4 2.4gHZ 2.0GB Ram I have tried to do some reading on this by googling and such, but it is all a bit overwhelming and so many posts/articles want to deal with dual booting which I am not planning to do on this machine. I am trying to find some info on whether it is better to have a separate boot partition. As in, separate from root partition. I have read that a separate boot partition makes for a quicker start and better recovery if system crashes. I will shortly be installing openSuse 11.2(KDE) [currently on 11.0] and I want to optimise the partition scheme so that it is the most efficient. I have a 160GB HDD that will be housing this new installation, so space is not a problem. I am only user on this machine. Currently, it is just partitioned as such:
2.0GB - swap [because I read it should equal Ram] 32.0GB - / 40.0GB - /home 76.8GB - extra storage [Not really necessary as I have 2 other HDD on system 1 - 320GB and 1 - 200GB]
Also, is it recommended to have separate partitions for /tmp /var or any other /nnn ?

I originally had my full hard drive as a full Ubuntu partition but I then re-sized that and installed Windows on a new partition. Now I guess the boot sector got overwritten and I don't have a choice to boot either Windows or Ubuntu. I know I have to reconfigure GRUB or another boot loader to allow the choice but I am not sure of how to go about that.
I've had Ubuntu 10.10 installed for a while and I recently cleared a partition to install Windows XP. However, when I load from the Windows XP boot CD, I get "7379one MB disk 0 at ID 0 on ?Bus 0 on atapi(Setup cannot access this disk)". I've tried just about everything
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:
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 ?
Where can I install grub? I know it can be installed to the mbr of a hard drive. I also know it can be installed to a /boot partition. Can I install it to a lvm partition? Does it have to be /boot? grub-install --root-directory=/boot /dev/hda Does this command install grub to a partition and link it to a separate /boot? I have fedora, but this is a live cd. I need to learn where I can install grub2 to boot
I downloaded the Fedora live dvd iso file, burned it to a dvd. I was wondering if I forgot to do something or did I do something wrong. When I try to install from the dvd I get this error message, isoLinux: Disk error 80 , AX = 42A7 , drive 9F Boot Failed: press key to retry When I press a key to retry I get the same error. I also tried to install virtual pc and get not boot disk found.
I had a a problem booting last night when my laptop battery came loose and caused a crash during boot.It ceased loading a daemon and I turned it off with the power switch, then I received the boot error,then i checked the linuxdrives directory and it was corrupt,I then, out of ignorance, ran wubi from within windows XP and said unistall believing that it would reinstall and fix itself.Thus you can see my green behaviour.I have been searching the threads and have tried many things but have had no success, I will suffer a great loss if I lose that load of Ubuntu as I have allot of work stored there, and in my Thunderbird accounts.
Is there a way to boot any current kernel without the nolapic flag on ICH8-based intel T7300 systems? This system works fine with the last 2.26 kernel from FC8, but due to EOL of the security updates I tried to install FC11 and FC10. The first sign of trouble is that their installation only works with acpi=off or nolapic options. As those options disable either fan-control or the second cpu-core I consider them undesirable. Is there a recent correctly working kernel available? Or do I have to downgrade to a distribution that uses a 2.26 kernel?
I was yesterday evening experimenting inserting a script into /boot/grub/grub.cfg. Well I broke grub.cfg and had to try to boot from a grub2 prompt.I have separate /boot and / partitions on /dev/sda1 and /dev/sda2 respectively.Working out the correct syntax for the boot to work was a little complicated, so I thought it would be useful to post the correct procedure here, in case anyone else has the same set up that I do (separate /boot and / partitions)At the grub prompt code:
grub> set prefix=(hd0,1)/grub grub> insmod linux grub> set root=(hd0,2)
I have 2 sata HDD, I wish to dual boot, but in a way to have Windows on one and Ubuntu on the other.
For some reason I could not get Ubuntu (10.04) to install from the live CD or Wubi or from Windows on the same HDD.
I downloaded the advanced distro and went with that straight onto the HDD and it has been a gem (love how it just works with no drama).
I want to install windows XP again on the 2nd HDD, as there is one game that I play in windows. (I've got it to work in Wine I just don't like / can't get used to it)
My Question is: installing windows on a 2nd HDD and then being able to choose which one to boot.
I've read about installing Windows after Linux in the user guide and reinstalling grub2 - I got the impression though, the they were installed on the same HDD and thought that what I want to achieve may differ?
I'm running 9.10 off of a 4 GiB CF card. I keep running into space issues with updates, so I purchased an 8 GiB replacement card. I've cloned the 4 GiB card to a .IMG file using DD.I've then copied the 4 GiB image back to the 8 GiB card using the Ubuntu startup disk creator program. Once done, I'm able to properly boot off of the new 8 GiB clone.Unfortunately, the clone ends up with 3.67 GiB of unallocated space at the end *see attached). I tried deleting the "extended" partition that the swap is located at after booting from a Live CD and the system was unable to boot after this. I was thinking that I would delete the swap entirely and create a swap file after I merged the existing partitions, but I was unable to do this.
best way to do this (e.g. get one large 8 GiB partition with my old image on it)? I still have the original untouched 4 GiB card and also have an external CF drive if I need to redo the cloning. I've also used Clonezilla before, so perhaps there's a way to do this that allow me to grow the image as it's being cloned.
