Installation :: Remove Ubuntu Distro Without Destroying GRUB2?
Dec 8, 2010
So I have my netbook triple-booted with Windows XP, vanilla Ubuntu, and Kubuntu Netbook (Installed in that order).
I however would love to remove Kubuntu Netbook from my computer, but unfortunately, since I installed it last, it is the Linux OS that owns the current default GRUB files that the BIOS reads first.
Can someone please tell me what to do to remove the Kubuntu partition and restore the default GRUB to my vanilla Ubuntu so I can still use my computer? I've done this incorrectly before and freaked myself out because whilst trying to access the GRUB, my computer couldn't find it because the partition that the files were originally on was gone. Haha. I don't even know how it got fixed.

I have the following on my hard drive
Ubuntu 11.04
Mint 10.0
Windows 7
I would like to remove Mint and recover that space for Ubuntu, but since I installed Mint last, I think it is "in charge" of the grub bootloader, so I figured if I just expanded the ubuntu partition then I would lose the bootloader and not be able to log into anything. Is this the case? what is the best way to remove mint while still preserving the grub menu.

So this morning i booted Xubuntu in an effort to replace Fedora 15, basically just getting a feel for all sorts of different distros. although it was slightly more confusing that the others i've tried on install because i had to manually configure partitions, and prompt didn't give a description really of which was which, so i took a shot in the dark at which was fedora to overwrite, and hoped i didn't remove win7 so all went well, but it appears Fedora is still in my system, using roughly 50GB still, it won't boot. but it is in the boot menu, and i can see it from Xubuntu. Can i remove this to add that bit of space to my new distro? or would i have to reinstall xubuntu Seems to be mostly just old folders and such, but it's being shown as a device. I don't see it in Gparted i don't think.

The person who installed my current Ubuntu (9.04) made a separate partition for the /home and I also have a large data partition. That person is no longer available for support.
If I upgrade to the current release (10.10?) will it identify the existing home directory and preserve it?
If not, what are the precise steps I have to follow to preserve my settings, and a lot of software that was not from the repository?

I am running a dual boot system with windows 7 and Ubuntu. Both have run smoothly on my machine (Core 2 quad core on Gigabyte board) I recently upgraded to 10.10 from 10.04 via the update manager within 10.04. Following the upgrade the initial boot failed at the login screen ( i simply got the purple colored screen with a white box in the center of it). Instead of trying to figure out what went wrong, I simply re-installed 10.10 from live CD on top of the upgraded Ubuntu that was failing at the login screen. The live CD install seemed to fix everything for the most part ( I did notice some quickly flashing text right before the login screen. I think it was an error message but it was too fast to read)
My problem now is that I am trying to remove some of my old kernels from the Grub2 boot screen and I cant. I have read many posts on how to remove the old kernels, but my system is proving to be difficult. The old kernels definitely show during boot, but whenever I go into Synaptic they are not there. I have downloaded Ubuntu Tweak, and they do not show in it either. I have read the information at [URL] I went to http://www.fixthecode.com/remove-hug...sts-in-ubuntu/ and thought this would fix my problem but I keep getting an error: "awk: 1: unexpected character 0xe2" when i try to run: "dpkg -l | grep ^ii | grep 2.6.3x-xx | awk -F{print $2} I am running kernel 2.6.35-22 The kernels i want to remove are 2.6.32-23 and 2.6.32-24.

I can't figure out how to remove a Ubuntu distro in grub that I no long have installed. I have Win 7, Ubuntu 10.4 installed but when I boot my grub menu shows Win 7, Ubuntu 10.4 and Ubuntu 10.10 that I have removed from my hard drive but still shows up in the menu. I have been trying many commands in the terminal menu to edit grub but nothing shows me how to remove a menu entry.

i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.
sudo fdisk -l

I have Suse 11.2 and Win XP running from a Grub2 boot loader. I want to remove Win XP from the machine.What is the best way to do that? Is it safe just to replace the partition that Win XP is on with a Linux partition?
Assuming that is OK, will Grub then boot OK, and recognise automatically that the Win XP OS is gone, or do I also need to update the Grub configuration manually? I did try looking at the Grub Wiki, but I find it very hard to use

I've been dabbling into linux by installing Wubi on my main computer, out of ease to install, but I use windows to do many things I'm not sure if I could do as easily in linux. Anyway, I had a macbook before I got my new main computer, and have been wondering if I can install linux on my macbook to test out other distros without potentially endangering my main computer (out of complete idiocy on my part, of course). Is this possible? Is there any specific "guide" out to do this?

I was dual booting on my netbook with Lucid and Windows XP, so the computer starts with the GRUB2 menu. I deleted the windows partition and now I only use Lucid on the netbook. I want to know how can I get the computer to simply boot into Ubuntu like a normal computer would do if it was not set up as a dual boot system?
How can I get the computer to go directly into the ONLY operating system rather than taking a detour through the GRUB menu?

I followed the Grub 2 Basics steps to remove Grub 2 kernel listings.
However I'm stuck with 3 older versions that was completely_removed from Synaptic (kernel/headers/generic), but remain in grub.cfg.
Quote:
Here is my current grub.cfg:
(How do I remove *.14 *.21 *.22 from my menu entries Ubuntu-tweak is not an option for me. I like it old-school or with the tools at hand.)
Code:
I considered changing permissions for grub.cfg, but update-grub and new kernels will revert my changes.

They finally got the MCP89 kernel patch finalized and released as a Ubuntu DVD in the daily build of Lucid Lynx (good job!). I tried it, but even after following Ubuntu's Wiki-guide to fix various problems, a lot of my Mac's functionality broke and I don't want to take up that battle yet (of trying to get everything to work perfectly {I'm a perfectionist}).So I want to remove Ubuntu and GRUB2 from my system. But even with some experience with problems like these, I'm in the ultimate pickle. OS X uses the GUID Partition scheme and EFI, whilst bootcamp has a BIOS/MBR emulator to run Windows. I installed the GRUB bootloader to the MBR (I think {In "/dev/sda" during the install}). I use rEFIt to chainload into GRUB2 to boot Ubuntu, and I want to remove that icon, return to booting Windows 7 using it's own bootloader, and restore the GB's that Ubuntu took back to the Windows 7 partition.
I'm lost and (for the first time in a while) WAY over my head. I have no experience with EFI/GUID. (I just got my first Mac a month ago)

I have an Asus Eee 1000H with win7 installed dual booting with the NBremix. I installed Adobe CS3 to the win7 side and everytime I run CS3 it wipes out grub causing me to use the live-stick and re-install grub.

I have a laptop dual booting to Windows 7 and Opensuse 11.2. However, I'd like to switch to a different Linux distro (probably Ubuntu, that's what I'm used to)
Is there a way for me to do it without losing the Windows 7 setup/data?

I'm running 10.04 LTS (64 bit) During a recent attempt at dual booting Windows 7, the Windows installer made a boot partition on the wrong drive, formatting the drive, and therefore destroying all my data.
The original partition was NTFS, and the new (unwanted partition) is NTFS.
Is there something in Linux I can do to recover the data that was there, or am I going to have to install Windows on yet another drive and use some Windows tools?
The data on this drive is extraordinarily important, containing ten years of digital photos, my source codes, and musical compositions (protools sessions etc).

I have a full install on a dedicated partition. And the problem persists. I have tacked it down to the driver for my video card [nVidia 9600m GS]. When I disable the driver, it somewhat returns to normal [it works fine on shut down, but boot up is still buggy]. However, this makes Docky complain about compositing [it will still work, but there's a black void around it] not being enabled. I also assume that lacking the driver will cause problems if I try to do anything 3D.

I am currently using the windows version of gVim to edit source files on a networked drive mapped to a linux system, as well as local files created in cygwin.
The problem is that the windows version of gVim destroys the original file permissions on the respective systems. IE: Files on cygwin are defaulted to 077. When edited by the windows version of vim they are saved as 777.This problem doesn't even occur when using ms-notepad (as well as all other editors I've tried), so I am not quite sure why gVim does it.
A possible solution would be to use cygwin's gVim for everything, but that's rather cumbersome as it requires running an x11 environment to support it, and it causes some problems when running some commands from within gVim (or vim for that matter) when working on the networked drive.
Any ideas how I might be able to maintain the existing file permissions?
This morning while on a different machine the problem with cygwin did not occur. Cygwin & gVim were the same version, however the other machine is running WinXP while the machine the problem is occurring on runs Win7.

I have a linux box set up as a multi-purpose server for my home with three Windows client PC's. The linux box is based on a slightly modified Slackware 9.0 distribution using Linux 2.4.20 and an unfortinately old, slow AMD processor with a miserable 512Kb RAM. The linux box serves the CIFS file system to the Windows boxes, runs the SQUID HTTP proxy, the Apache web server, a print server, does masquerading, mail serving and a very effective firewall using iptables.
This system, although slow, has run perfectly for several years.Let me say that again - This system works perfectly.I had decided that now is the time to upgrade the hardware, so I bought a Gigabyte LGA775 motherboard which has two 1Gb network interfaces on it, an ASUS 256Mb PCI-E display card, 2Gb of DDR3 RAM, an Intel Core2-Quad processor and a bunch of 500Gb SATA drives to set up a RAID5 array (but I intend that the system boot off one of several 40Gb PATA drives I have).I set up the processor, motherboard, display card, RAM, a SATA DVD Drive and a 40Gb PATA hard disk in a "breadboard" layout and installed distro 13.1, being careful to set up the static IP for the local network, dhcpcd to get an IP address from the cable modem (my internet connection) and to enable ip_forward in the network configuration.
Then I installed a script invoked by /etc/rc.d/rc.local which installed all the SAME iptables rules as my old Linux box. There was one minor glitch when I had to change 8 occurrences of "-d ! $LOCAL_NET to" "! --destination $LOCAL_NET" but that was no problem. I also set up /etc/resolv.conf, /etc/hosts , the BIND server files etc. etc. exactly as in the old box.
I am able to ping mirror.aarnet.edu.au (this is at the heart of Australia's internet hub network - if it's down the whole bloody thing is down) and have the system find the correct IP from the designated nameservers and contact that server with a return trip time of 35ms. I am able to run a telnet session from one of the Windows boxes and edit files on the Linux server. So both network interfaces work and I've got them the right way around.I am able to run FTP on one of the Windows boxes and connect through to mirror.aarnet.edu.au, although it seems to hang when I try a DIR (but then so does the old linux system).

I installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.
Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.

If I install let's say Mandriva after Ubuntu, can I then just delete the partitions that it made to get rid of it or will this affect Ubuntu or else how can I get rid of it if I don't want it?

I'm about to receive a new Zotac MAG MAGHD-ND01-U and I'm wondering if perhaps it would be smarter to install UNE instead of the standard distribution. The computer will be used almost exclusively as an HTPC using Boxee. I've read that UNE has atom optimized code; that along with a smaller footprint may speed up the overall system.

I have decided to dual boot again because I found a old hard drive laying around.
primary drive: sata 500 gb
ubuntu 10.4 64 bit installed with
boot
[code]...
secondary drive: 120 gb ide drive with xp installed. xp was installed first and wrote the mbr to sda1. I then installed ubuntu 10.4 and it overwrote mbr on sda with grub2. I have tried every combination of the 40_custom script for xp I have found here on the forums but to no avail. The 30_OS probe never seems to see it either. Grub 2 will not see xp. I have it in the menu from the custom_40 but it just reboots the system when I choose it. Any advice is greatly appreciated as I am ready to go back to legacy grub which only took 5 minutes to dual boot last time I did dual boot. I want to give grub2 a chance, since it supposed to be better, but I am getting frustrated.
Here is the output from the boot info script.
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 #1 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb
