Fedora :: Install Grub To A Partition And Link It To A Separate /boot?
Nov 20, 2009
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

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

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?

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"

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]....

Compiz settings, my entire GUI would freeze up after the startup splash. It did the little ubuntu jingle and so on but wouldn't actually load up the desktop. I would've booted into recovery mode and deleted the settings that were messing it all up for me, but pressing ESC during grub did nothing! So as a last effort I reinstalled Ubuntu (Karmic) from the live CD on the first partition only, but I don't know how to make the second partition (with my old /home directory) the normal /home directory. The instructions linked above seem to require having done the whole process of moving the partition (so as to create "old" and "new" dirs, etc.).
So there are really two problems here: 1) How does one restore things to normal when a few too many cheeky moves with the desktop effects turns everything to pot? And 2) How does one reinstall Ubuntu with a separate /home partitions

So I need to become the root user in order to edit a grub file in a seperate partition, so I can get back into this partition. How can I become and stay as root user in the desktop environment? (I know you shouldn't do this, but I need it.)

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 ?

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?

I am triple booting
Windows xp
UBUNTU 10.04
Fedora 13
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).

I have PC with following specs:
Intel E7500 CPU / Intel G31 Motherboard
Kingston 800MHz 2GB RAM
Hitachi 500 GB SATA HDD + Seagate 160 GB SATA HDD
I initially had only 500 GB HDD. I installed two installations of Windows 7 Ultimate - one 32-bit and one 64-bit installations. Both working fine.
Later on I installed the 160 GB HDD and installed Fedora 13 in it in a partition. The rest space of the 160GB I am using with Windows for storing data.
Now, the boot entries of both Windows installations are in the Grub Loader of F13. Means, if I remove the 160GB HDD, I cannot boot into my Windows installations.
Now I want to remove the 160 GB HDD and install a new 2TB hard-drive. That way, I cannot log into my Windows. And I do not want to lose the Linux installation also.
How can I remove the 160 GB HDD and install a new one without sacrificing my Windows installations?
OR...Is it possible that I can copy complete image of F13 on to the new HDD, so that things are same for the Windows installations?

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 have been a happy little GRUB user for a while now, but now I want to use GRUB to boot a physically separate WinXP hard drive, and I can't seem to do that. Normally GRUB is easy, (I even have a nice splash screen of my own making). Its a champion solution for booting into Ubuntu Linux on /dev/sda5 or Win XP on /dev/sda1.
My second HD which Linux recognizes as /dev/sdb, has a Win XP boot sector and Win XP in one partition.
Normally I boot off /dev/sda using GRUB, and from Linux I can mount and have access to /dev/sdb - that works well. Occasionally however, I need to boot the separate Win XP system on the second HD, and to do that I switch the boot drive in the BIOS, but lately that is getting to be a bit tedious.
Initially I though to give the additional boot choice to GRUB, I simply had to edit /boot/grub/menu.lst and point to the second HD (where /dev/sdb = hd1 in GRUB speak). Unfortunately, when I select the new choice, it simply boots Win XP off the first HD.
I'm confident GRUB does look at the first partion on hd1 as expected as I can induce an error by having hd1 disconnected, or write silly partion numbers into menu.lst. So if it does in fact find the first partion on hd1, why doesn't it boot? Why does it default to WinXP on hd0?
I have diligently tried physically swapping SATA drive cables and playing with bios switching and have messed about a fair bit with menu.lst to make sure I have drive and partition numbers right, but all to no avail. I have also tried changing rdisk(0) in boot.ini to rdisk(1) on the second drive when it is not the boot drive.
I'm afraid the only other thing I can think of is that the second hard drive requires a Linux boot sector if I am going to boot it up from GRUB, but somehow that doesn't make sense. Surely GRUB can work across physically separate drives, so I'm open to other ideas first.

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 want install 10.10 Maverick on a new partition alongside my OS X and 10.04 Lucid installs to see if it works on my machine. I'm a little unsure about some things.
1)Do I need to install the GRUB boot loader on this new partition?
2)Can I use the same swap space or is recommended to create a new swap?

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 have fedora 12 installed on a laptop with an LVM partition, /dev/hda5 logiacal partion in the /dev/hda4 one, a boot partition on /dev/hda3 and a FAT on /dev/hda2 for win data. There was also a 10GB free partion left from older works on /dev/hda1. Now the /boot partition was set to only 0,2GB and this conflicts with the kernel updates. I freed the 10GB section, formatted it to ext 4 and copied all stuff from the /boot sector on it. now the old /boot is mounted in the grub.conf on a UUID and not the /dev/hda3 as it comes up on fdisk.
I would now like to swith the boot from the small /dev/hda1 partiotn to the larger /dev/hda3 one, but don't know how to manage it with grub (fedora, i understand it's grub-legacy).

I'm using fc14, and put the /boot directory on a standalone partition. Now, there's something changed in MBR, and the grub has been overwrote, now I wants to fix the grub by another bootable usb-disk with grub, to use 'setup (hd1)' to fix it. but the situation cause the /boot has nothing and the partition contain essential files does not under the directory 'boot'. then setup failed.

I want to get into the Linux world and trying to install openSuse 11.3 on a separate partition, so I can start getting familiar with it. Installation started and PREPARATION was OK. INSTALLATION WAS OK. While doing Automatic Configuration after a little while the program stops (it hangs). I have to restart the computers by pushing the hdw reset button.
At next reboot, at the partition menu I choose openSUSE option; the program starts and after a while it says that previous installation failed and ask me if I want to retry. I do choose yes, but than again same thing happens - hangs and does not complete automatic configration (which by the way seems to be the last step of the installation). PC is a 2,8GHz, 1GB RAM, Windows OS XPHome and Service PAck3, and now partially loaded openSUSE11.3. OS

I have a dual boot system with Vista and OpenSUSE 11.3 . Linux is distributed over 2 partitions: one for /home and one root partition for all the rest. As this root partition is getting filled, I thought of taking a 10 GB partition from the Vista partition and using this for the /usr folder (= 6 GB). This partition is a primary partition, while the rest of Linux is on secondary partitions.To be save, I renamed the existing /usr to /usr-old and created an empty /usr as mount point. I changed fstab to load the root partition, the /usr partition and then the /home partition.But when I started the system, there were a lot of errors about files not found in the /usr folder, lthought this folder and is content were clearly present when browsing the filesystem. What went wrong? Hard links? Other system configurations to change? Not possible to put /usr on a separate partition?

I just bought a new hard drive so that I could convert my XP-only machine into an XP-Ubuntu-Windows 7 triple boot machine.Since the drive is absurdly huge (1 TB) I wouldn't mind throwing ReactOS into the mixtoo.I just found out that master boot records are limited to 4 entries, meaning 4 primary partitions. I had Windows XP set up on my old drive as a boot partition, a program files partition and a media partition. Since I really didn't want to install XP from scratch, I cloned this setup on my new drive.
This leaves me one MBR partition entry for installing Windows 7, Ubuntu and ReactOS. I'd like to avoid having to install XP from scratch like the plague, partly because it's supposed to be a safety net in case things go wrong with my other OS's and because I've invested a lot of time getting it set up exactly the way I like it.Here are the options I've considered and why I don't like them:Install Windows 7 on my media partition. This would work, but I prefer to keep my media partition completely separate from any OS, so that I can reformat an OS partition without affecting my media partition at all.
Use wubi or something to install Ubuntu in the same partition as something else. Again, this is brittle.Move all my media to a logical drive on an extended partition. Create another logical drive on this extended partition for Ubuntu. The problem here is that extended partitions are rather brittle--if you nuke one, it renders the rest useless.Just put the old drive back in my computer and run XP off it. Use the new one for the other OS's. The problem here is that the old drive is slower and uses extra power, generates extra heat, etc.

I'm trying a fresh install of 11.2 but I couldn't figure out how to make the whole installation on the same logical extended partition.
It always wants to create a separate /home partition.
I have a second HDD with NTFS only for backup purposes, but the installer puts a grub entry for it too (windows 2). And this HDD is not even bootable. I don't have the balls to try to boot from it and see what happens. How to get rid of it?

Saw a reference to putting the swap partition on a separate drive--just minutes after I was considering that approach. Can't find anything recent on the topic, so asking: Is there an advantage to having /swap on a separate HD from data on /home? My thought was that both disks could be active at once, perhaps speeding up a busy application.

I am setting up a LAMP server for my home LAN. I want to move the data out of / into a new disk partition for ease of backup and especially away from any clean installation I might do. What
I have in mind:
Shut down MySQL and Apache
Make a new partition, format as ext4
Mount new partition on /mnt
Copy all of /srv to /mnt
Copy MySQL stuff from /var/lib/mysql to /mnt/mysql
Update /etc/my.conf to point to /srv/mysql
Unmount /mnt
Update /etc/fstab to mount new partition on /srv
mount /srv
Start mysql, apache
Will a fresh install or upgrade keep its fingers out of /srv, in the same way as /home? Or will those parts of apache installed in /srv/www be updated?

using Opensuse 11.3, I have used Ubuntu 9.10 in the past and have had a blast with Linux. I have to rehash some of my old skills that I have forgotten in the past several years..I installed 11.3, everything is working fine. However, I just releazed that after I installed it, I used my whole partition (Not Windows 7, or I would've been in hell). My Windows 7 is in Raid 0. My second HDD is 1 TB and 11.3 is on there. So, how can I trim down let's say 100 GB and just give the rest to Windows (800gbs). I need that much because I do editing for videos, etc. So, once again, how can I trim my partition and use it for Windows 7.

I recently put ubuntu on my laptop in hope that most of my games would run through wine, some did and some didn't.
Anyway, long story short, I have ubuntu on my laptop and I want to re install windows onto a separate partition, keeping my ubuntu instillation in tact and set as my deafault OS.
I'm very new to ubuntu and the only guides i've seen are fairly complex. I was just wondering if anyone could point me in the right direction? p.s. Is there maybe a way to create an image of my current ubuntu nstillation/settings/apps etc. just in case I do something wrong and lose everything?
