Slackware :: Uninstalling Grub - Cleaning The Mbr
Dec 14, 2010
I'm dualbooting Slackware and Gentoo on my homeserver. Some weeks ago I built grub with a slackbuild-script, it was the new version of grub but it did not install properly. Since then I could only boot Slackware but not Gentoo. Today I tried to install grub from the Gentoo-partition (I chrooted to Gentoo). This did not work due to an errormessage of grub that "stage1 could not be read".
Afterwards I tried to install lilo, this failed at first attempt, but the with some warnings lilo executed. When I rebooted after the lilo-install, I had grub again at the bootscreen without the option to boot Gentoo. I decided that I have to clean the mbr of /dev/sda and found a solution with the dd command. Here my
[Code]...
Fortunately I have a second disk /dev/sdb in the server and have now installed the bootloader on the mbr of /dev/sdb. But in the long run I want to change this.

Would like to ask for some advise regarding GRUB. I have been using Windows for a long time and recently have finally decided to switch to Linux. A good friend recommended Ubuntu and I have installed it on an 8GB USB thumbdrive for test drive. Nowadays, I mainly boot from this thumbdrive for my personal computing use. [I am a supporter of the "Immersion Learning" school. The only way for me to really learn is to force myself to use the system ] as I frequently updates my Ubuntu 9.10 via the Update Manager, I found my GRUB screen now have multiple entries like below:
[Code]....
I would like to remove the last 4 lines but:
1. I'm not sure how to do it?
2. And do i just delete the entries or do i also have to delete some system files? {this is important as i am running this on a USB thumbdrive and would like to remove any files that are no longer necessarily and keep the installation as lean as possible}.

I see too many entries upon turning on my laptop: [URL]..There should only be 3 entries: Windows partition, Ubuntu partition, and the memtest thing, I believe. The *doubling* up of Windows and Ubuntu is due to me wiping Ubuntu, then reinstalling Ubuntu. The third entry for Ubuntu is due to re apt-get install'ing gnome-desktop. How can simplify the menu?

I have two leftover entries in the Grub2 menu after running update-grub. One is leftover from an Ubuntu installation under Windows 7 referring to a Vista boot. Never had Vista on my system, and if I were to select this option it will lock my computer. Same deal with an older Jaunty boot option - as I have identical worded options one good and one dead option.
If I have to live with these two dead selections on my Grub2 menu I will. But I'd rather get rid of them. I don't want to use an old tool for Grub editing that is no longer workable for Grub 2.

When you unsuccessfully try to install software, does your Slackware system become cluttered with unused files? Is there a program, other than 'slackpkg clean-system', that can review your installation and identify any useless stuff? My tmp directory is set, in fstab, to delete its contents on boot. Is the tmp directory the only directory to be concerned with?

I made a slight mistake after editing my partitions with Gparted. I accidentally installed Grub 2 on my Ubuntu partition instead of re-installing it on the MBR.
I've since installed Grub 2 on my MBR, but how do I get the Grub 2 installation off of my Ubuntu partition?

installed a couple things with Winetricks and it told me to uninstall the Samyak/Oriya font because it causes problems with some .net applications. It told me to use
Code:
But I'm not sure if I should install dpkg specifically to do this, or if there's a native slackware way to remove this.

And by blank screen I mean after I pick whatever I want on GRUB. There's NOTHING.I even tried going in recovery mode. But same thing.Right now I'm using an older recovery. The newest thing is completely broken. And the regular one for the Ubuntu version doesn't work either.

I installed Backtrack 4 and it is set up as a dual boot with my Windows 7 x64 bit. I want to uninstall Backtrack because I am going to put it on a different computer. The problem is - I can't do it. My laptop is an Asus K61IC, and it doesn't come with an installation CD, because the OS was factory installed. It comes with a recovery wizard instead, which gives me the options to 1) recover to first partition only, 2) recover to entire HD, and 3) recover to entire HD with 2 partitions. Because of Grub and it asking for me to choose what operating system to boot when I start my computer, when I recover Windows 7 to the entire HD and try to boot, it gives me Grub error 22. I need to fix my MBR so that the grub menu is also deleted and all of Backtrack 4 is removed, actually letting me back onto my Windows 7. I need a way to delete the Linux partition, and fix the MBR, but I don't know how to do that because I don't have an installation disk.

How do I uninstall unwanted applications? Is there a log of all installed applications? When I ran setup and chose my packages, for KDE, and I am sure others the options came in bundles, ie KDEbase-version... Is there a way to see all package contents to remove individual programs?

I have a dual boot Vista/ Kubuntu and my vista SP2 has made both my vista and kubuntu unable to boot completely. I've been through many steps to recover vista but no restore point works and such so I am going to use my Toshiba recovery partition to reinstall but what I'm wondering is if after I do that will the grub loader be affected and give me the error 22? The two are on separate partitions and I've been meaning to get rid of Kubuntu from my laptop since I have it on my pc

I have two hard-drives. The first, C: (sda1) has Windows 7 x64 installed on it. The second hard-drive, D: (sdb1), was partitioned when I installed Ubuntu 10.04 into two separate partitions: NTFS and Ext3.
I wanted to remove the Ext3/Ubuntu partition and reclaim that space (i.e. completely remove Ubuntu). I did NOT install using Wubi. I booted up Win7 x64, went into Disk Management, right-clicked the D: partition corresponding to the Ext3 filesystem (shows up as unrecognized in Disk Management), and opted to delete the volume. I then right-clicked on the NTFS D: partition, and opted to Extend the Volume to reclaim the previously partitioned space.
When I rebooted, I ended up with the following error:
Code:
error: no such device: f81368be-ea53-43d2-b8de-bb52b5ac322c.
grub rescue>
I cannot get beyond this screen. Rebooting always puts me at the grub rescue prompt. I have looked at the HOWTO: Purge and Grub Rescue Prompt threads, but was not able to understand the instructions and am therefore asking for your help. However, I was able to install the boot script as those threads suggest, and here is my results.txt:
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 #2 for /boot/grub.

how to uninstall packages via the program name? For example, if I want to uninstall the program "KWordQuiz" then I would usually have to use the command removepkg -package name But unfortunately I have a fresh install and want to get rid of a lot of programs. So instead of using the package repository and finding each package which would take days (maybe) and removing them individually I'd like to remove a program and all its supporting packages. I am probably just rambling on... Umm, so yes is there a way, or do I have to suck it up and sit at the keyboard for days.

I can't track down..On most of my Slackware -current installs (I have 6 installs altogether) I can no longer get conky to adjust via .conkyrc Conky from SlackBuilds The problem is for some reason it's stuck at top of screen, with the whole upper-half not visible off screen.. I have tried adjusting .conkyrc, tried uninstalling/reinstalling tried adjusting how it starts in .fluxbox/startup all to no avail. I am starting it with either
conky -d
conky &
conky -d &
all the same result. Somehow I "fixed" one of the installs, and tried the same "fix" on the others and it didn't work..I am also trying to start either fbpanel or lxpanel either before or after conky...same results Is there another app (not gkrellm) that will do same as conky?

I've just installed Ubuntu after my windows os became completely infested with trojans and viruses. How do I get rid off windows? I can't get rid off the viruses because I can't install an anitvirus for some reason. It's still there when I start up the computer. I don't think I'm using grub, though I'm not completely sure. Is there a way to verify this? On a similar note, can the trojans and virus affect on windows affect ubuntu?

After figuring out that this is happening on my brand new 10.04 install, I've suddenly realized it explained what was happening on the 9.10 install I'm replacing.
I'm finding out on the internet that /tmp in Ubuntu is typically a Ramdisk, thus cleared automatically on reboot - but that's not how I was ever taught to setup a linux box; I *always* create /home var et al and mount them separately, including /tmp.
So on my new 10.04 install I am informed my tmp partition is down to 12 Meg, and find K9Copy crashed last night (I initially thought this was due to a crash, but testing shows it just - leaves them there. K9Copy!) leaving a 4.5 Gig file sitting in tmp. I add a couple Gig to the tmp partition (LVM rocks btw.) and reboot. Files are still there.
I finally went in via gksu nautilus and manually deleted the data.
More research find this results in exactly the kind of issues I was having previously in my 9.10 install (albeit without the helpful warning that helped me figure it out) of Firefox and various other programs acting glitchy because they right to tmp and it's full.
I'm a n00b, and really don't know how to fix this - the 'proper' way to clean tmp seems to involve dropping entirely out of X to userlevel 0 and running from the commandline?!?! . . /tmp is supposed to be for temporary files; ideally a program should clean up after itself, but it's actually Ubuntu's job to clean this.
My going in and manually cleaning out files is insane if gksu nautilus is involved, nevermind if that's the *wrong* way. I'm certainly not the guy to write a cronjob to clean this. On the other hand - this only started in the last week or so (on 9.10) so it has to be a recent change.

I have enabled the option to keep the yum cache when updating Fedora 12 and I was wondering if there was a way in which I could remove old versions of the same package from the cache?
I have Fedora installed on more than one machine and I make them share a common update location for their updates to avoid downloading the same packages twice (bandwidth quota expensive in Australia).
how I could accomplish that? yum clean doesn't seem to have any options to only remove old packages!!!
Example: The yum update cache has:
wireshark-gnome-1.2.5-3.fc12.x86_64.rpm
wireshark-gnome-1.2.6-1.fc12.x86_64.rpm
I wish to only keep the most recent version that is wireshark-gnome-1.2.6-1.fc12.x86_64.rpm, but for all the packages.

I'm writing a script to clean my computer.
Everything is good to go except i have no clue how to clear firefox's history and whatnot from the command line.
This is one of the commands i found...: rm .mozilla/firefox/linux-blog.default/cookies.txt
It tells me no such file or directory.

I was installing a few programs when my computer froze, I rebooted, and the installations never finished. I didn't log in to ubuntu for several days, and forgot the exact programs that I was trying to install. Now when I try to open up Synaptic Package Manager, I get this error:E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. E: _cache->open() failed, please report.I can't install certain programs, etc.Something is screwed up. I think it has to do with the failed installations.

If we update or remove some packages (in addition manually installed software), some files such as previous version dynamic lib files are left, so it may conflict with new stuffs sometimes. Is there any efficient way to remove these kind of orphaned files all, automatically?
