Ubuntu Installation :: How I Could Re-access Or Re-install Original Grub
Oct 27, 2010
I've been using Ubuntu for a couple years, and have really enjoyed the experience. Recently though, I also felt like installing Arch Linux onto my laptop which already had a Vista/Ubuntu 10.04 partition. In doing so, I lost access to the Ubuntu partition on my hard drive. The Arch linux grub had replaced the Ubuntu grub.
So the main question is, does anyone know how I could re-access or re-install the original Ubuntu grub? If not, then can someone help me with adding a boot option in Arch's Grub? I've already tried some things, though obviously, none have worked so far.
I just installed 10.04 to the second hard drive on my system, and stupidly installed the new grub to the first drive, which has my standard 9.10 OS on it. Now I cannot boot into my original system. All of the files across both disks are still intact and mountable. I'm not new to linux in general, but I'm not exactly knowledgeable, either...
A few days ago I installed my first Linux product, which is Debian 6.0, and I installed the GRUB booting device on my main boot record, as it was suggested that it was a harmless step to take. Unfortunately, some quirk in my system made GRUB believe that I had XP when in fact I have Vista, so the options I have now are to boot Debian or to boot XP which is not on my computer. In other words, I have to get rid of GRUB now, but I'm realizing that he's not such an easy customer to kick out. I have moved my Linux installation to another drive, but the old GRUB always stays in place, and my Vista is stuck there frozen for eternity. So after considering all kinds of possibilities, I have come to the conclusion that the easiest way to restore my original boot record would probably be to find its backup copy that I assume the installation program made, and to copy it back into the right address at the beginning of the disk. I don't have the Vista recovery CD, so I really have to do this manually. So now my questions are these: did the installation program make a copy of the boot track, and if so, where did he put it and under what name, and finally, what command can I use from within the Debian terminal, which is now my only tool left, to copy the content of thesaid file into the first 512 bytes of the hard drive? I know that would be a simple matter for any serious geek, I guess I must be a little rusty. Anybody feel up to it?
I just did a fresh install from 8.04 to 10.04 with separate "/" and /home partitions. I really wanted a new 10.04 system to start from scratch and rebuild it again & differently. Instead I got a really messed up system. Is there any way to change it to a fresh new 10.04 install. That nothing has been added to yet?
This is very important because on 10.04 my video card won't handle all the mods that I had on 8.04 and my system freezes very soon after I log on.
I think this is the default view of GRUB2 as installed by some other OS, (I think Chameleon)... But even they must have done this by editing something in the original GNU GRUB 1.97. Is that possible to accomplish. If yes, how?
I'm running Karmic Server with GRUB2 on a Dell XPS 420. Everything was running fine until I changed 2 BIOS settings in an attempt to make my Virtual Box guests run faster. I turned on SpeedStep and Virtualization, rebooted, and I was slapped in the face with a grub error 15. I can't, in my wildest dreams, imagine how these two settings could cause a problem for GRUB, but they have. To make matters worse, I've set my server up to use Luks encrypted LVMs on soft-RAID. From what I can gather, it seems my only hope is to reinstall GRUB. So, I've tried to follow the Live CD instructions outlined in the following article (adding the necessary steps to mount my RAID volumes and LVMs). [URL]
If I try mounting the root lvm as 'dev/vg-root' on /mnt and the boot partition as 'dev/md0' on /mnt/boot, when I try to run the command $sudo grub-install --root-directory=/mnt/ /dev/md0, I get an errors: grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea. grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.
Somewhere in my troubleshooting, I also tried mounting the root lvm as 'dev/mapper/vg-root'. This results in the grub-install error: $sudo grub-install --root-directory=/mnt/ /dev/md0 Invalid device 'dev/md0'
Obviously, neither case fixes the problem. I've been searching and troubleshooting for several hours this evening, and I must have my system operational by Monday morning. That means if I don't have a solution by pretty early tomorrow morning...I'm screwed. A full rebuild will by my only option.
I installed windows 7 after I installed fedora so now i can't access my fedora OS. I've tried all the guides I found on the internet but fedora 10/11 guides doesn't seem to work for 12.
So I want to install the original version of Fedora 15 and make it dual boot with my Windows 7. Problem here is that I don't have a cd/rom. and the iso file didn't have a .exe thingy.....
so now what? Also this is my partitions> http://img94.imageshack.us/img94/9853/unledtlh.jpg
When I installed 64 bit OpenSUSE Gnome 11.4 today on an ext4 primary partition (sda4) from the Install DVD, it eliminated LinuxMint 9's entry from OpenSUSE'sGrub The 64 bit LinuxMint v. 9 (Isadora) is installed on an ext4 logical partition (sda9) inside an extended partition, but it doesn't appear in OpenSUSE's Grub (and now OpenSUSE 11.4 won't connect to the Internet - although the Live CD ran yesterday without a hitch).
I'm hoping that my fellow OpenSUSE users can help me regain access to my Isadora installation and hopefully, point me to a solution for the Internet access problem.
My machine is an hp 2133 mininote. It came factory installed with Windows vista, which repeadtedly crashed on me. To compenstate for this i installed gOS to dual boot with Vista. This was working fine but I was recently given a Windows 7 install disk, so I decided to upgrade. Windows seven installed without a problem but now I can't access the GRUB bootloader, windows 7 just loads automatically. I tried to restore it using the Super GRUB Disk usb utility but it didn't work, windows 7 still boots regardless.
I was messing around with the partitions and accidentally y deleted the ubuntu partition! I have Windows 7 as a dual boot but I can't access to that OS anymore. The message that I get is: error: no such partition. grub rescue>
I just upgraded from 9.04 to 9.10 (using Update Manager) in an attempt to get to 10.04. Installation and upgrade seemed to go OK until reboot. Now I only get a black screen - I don't see the grub menu, I don't even see any way to access the BIOS menu- not even a blinking cursor. I can hear it start and I can see the numlocks key go on. Ctrl-Alt-PrtScrn-B does not reboot (nor does Ctrl-Alt-Backspace- but I didn't expect that would) Surprisingly Ctrl-Alt-Del does (or at least it sounds like it does) reboot the system. I do have a NVIDIA cards and after reading around I suspect that this is likely the problem but I have no idea what to do now..
Here's what I've attempted: I figured since I wanted to get to 10.04 anyway and this was so troublesome I could just go do a fresh install with a Live CD or USB to 10.04. However, even with a live CD or USB I still just get a blank screen. Continually holding down F2 (and other function keys to try to access Bios) Holding down Shift while booting Esc while booting Moving the monitor to the VGA port (as opposed to the NVIDIA card).
Other information... Previously I had tried to upgrade to 9.10, but ran into problems with it not recognizing my RAID, so I just found it easier to go back to 9.04. (So although this is likely a graphics problem I guess the possibility is that now it doesn't even see my boot drive- although- if that was the case, I'd assume I wouldn't have the same problems from the CD or USB boot.) My ultimate goal is to get this to 10.04, if I could do it with an upgrade instead of a fresh install I'd prefer that, but at this point just getting back to a functioning computer would be ideal. I see many options in other posts for how to get back once you can access a command line- but since I can't even see that, I'm not sure what to do now.
I have an hp laptop and i had ubuntu on it for 3 years. my hard drive started to fail a while ago (i had ubuntu 10 on it until 1 week ago) and a then it all went black...I took the laptop to a repair shop, they told me it was the disc, so i bought a new disc, installed it on my laptop and reinstalled the new ubuntu 11. so far so good. i have now a working OS, internet connection and i can in fact type this message.
The thing is: all my files are on the old drive, which doesn't load/boot/start/read anymore. I have tested it on some friends's pc, tried a few HD disgnostic tools, they all send the same message: "fail"
I then tried to mount my old drive (with all my precious files in it) on my laptop as an external drive (usb) hoping that ubuntu 11 could read it as an external usb key: it gets read by the system, but it shows no files at all. it also shows an error message saying the drive can not be mounted, with some "sdb1" thing. i am sorry but i'm really dumb when it comes to tech language.
Then i tried to boot it on start-up but i got the grub rescue> thing and nothing else, just a sad, blinking cursor to recover my files,i have also tried testdisk but couldn't understand very well how to use it, and then photorec, from which i recovered bits and pieces of files, with no name. some of them are just parts some of them are complete.
My problem is: i have to get access to my files, as I use them for work, i couldn't do a back-up recently and i have some real important deadline to meet... for which i need those files. is there any way i could solve the grub issue and have that drive load/mount again as external usb?
I want to use the original KDE menus. The openSUSE menus are good if you have a lot of software, but I don't use a lot. For example, in Internet category, I only have 4 applications and I think is very boring have a lot of submenu. Can I install the original menu?
They were controlled by BIOS for start-up without problem.Just wiped out Fedora and installed Ubuntu 9.10 64bit. During installing GRUB I saved it on Master, IIRC.Now Ubuntu and Vista startup are controlled by boot loader. I have to start Ubuntu first and on kernel selection select (loader)(on/dev/sdb1).Then Vista starts.It works.How can I restore to its original setup?Their booting is controlled by BIOS.
suppose that we wanna install a program, so we must do this : sudo apt-get install program_name after installing that file, yeah indeed we can run that program, but where can actually we find the original-downloaded file in our ubuntu?
Is there a way to get rid of the need to feed debian apt-get upgrade the original installation cd-rom? I'd like to have all on the hdd and point there in order to avoid having to take the cd-rom along.
So, my disc was out dated, so my friend let me use his, because it has TBC on it, and he also let me borrow lich king. I can't install The Burning Crusades, or even the original WoW from the battle chest disc. I get the error in the image.
i upgraded to ubuntu 9.10 from 9.04 today .but after upgrading so many errors crept in . and these are following .. 1. Original login screen of ubuntu 9.10 is not being displayed. 2.By mistake i removed volume control and network connection applet from upper pannel.so can any one tell me how to re organise the pannel...and get back those two applets or can any one tell me how to completely recover the upper pannel.
im running ubuntu 10.04 since Beta, using a couple of external packages. Since the new release I would like to go back to the original packages in a simple way, the problem is that this particular one (xorg-edgers) has so many dependencies that it is impossible to go back from synaptic.
i'm trying to install ubuntu on a sony vaio. Unfortunately i cannot boot from a cd on which i have burnt the .iso file of ubuntu. The only way i managed to install ubuntu was by creating a usb bootable stick, but here also that doesn't work so well. My workaround was to use virtual clone drive which is freeware to simulate a cd rom in windows and get the iso file started. By leaving the bootable usb stick in the computer in this way it worked...
So in the end i have grub and can load ubuntu and win xp, but then by trying to format the harddrive i kind of messed things up and had to reinstall windows. Because the DVD drive only reads original cds. So from there i will attemp to reinstall ubuntu again. But how can i get rid of win xp afterwards ? If that CD Rom would only read burnt cds or if it would habe been possible to boot from usb then i wouldn't have this trouble.
When I first installed openSUSE 11.4 the /boot directory looked like this:
I had installed VirtualBox through Yast and decoded to delete. After deleting the /boot directory looked like this, pointing now to the desktop kernel.
I went into YAST and deleted all kernel entries that contained desktop, trying to get back to the original configuration.
After doing this, the /boot directory now looks like this.
Is there any way to get back to the original kernel configuration without having to do a complete installation?
I was in real doubt where to put this, so I hope I picked the right forum; otherwise, my apologies!
I want to build Roadsend PHP on my system. There seems to be no way to do this with the package manager, so I have to build it from source.
Turns out it depends on something called 'Bigloo'. Again no luck with the package manager, so I had to build this one from source too.
I took version 3.0c (Roadsend website recommends this version), did a
Code: ./configure && make && make install
, which did the job. Builing Roadsend worked, but I got a runtime error, which had to do with the Bigloo version.
No problem, I tought, then I'll just install Bigloo 3.1a. I did a "make uninstall" in the 3.0c dir, and tried to build 3.1a. This also worked, but now when I try to make Roadsend, I reports:
Code: *** ERROR:bigloo.heap: Release mismatch -- Heap is `3.0c', Bigloo is `3.1a'
So, somehow, there are still traces of 3.0c on my system. Maybe some file that didn't get deleted or some table entry that hasn't been undone?
My question is: How can I remove all traces of this version? Apparently, "make uninstall" is not thorough in this case.
And: Is there a general solution to remove everything when I did a "make install". So that my system is in the same state as it was before I ran the command?
I managed to break my video4linux module rendering all my video devices useless, can anyone tell me how to reinstall it on Debian Lenny as per the original install. I'm looking for the original one and not v4l2. 2.6.26-2-686
I installed Ubuntu to a flash drive and it worked all dandy like. However, on other computers the audio doesn't work, neither can I install a driver for the graphics card to use effects and (at least so it seems to me) run 3D games. Is it trying to use the same hardware that it did on the first computer I used and therefore hasn't installed the right stuff?
EDIT: I can 'play' music, so I think the codecs are fine, but no audio comes out, so I'm thinking it must be a driver problem.
EDIT2: Apologies, I checked the "Comprehensive sound problems solution guide" and was able to fix the audio simply by unmuting the speakers. However, the graphics problem remains.
One other tid bit that might be relevant is that the first time I booted up on a different computer it did tell me (in different wording) that the graphics might have trouble because it was set up for a different hardware system, so I told it to set up a new configuration and that seemed all dandy.
I recently installed opensuse on my computer due to it contracting a virus and not letting me reistall the original operating system on it. but i know nothing about this program. i have almost everything up to date and working on it. one thing i find strange is when i try to update the flash or java on it that i have to do all this extra stuff to get it to run. i do not know what programs to pull up to type the stuff down thats given in the java installation instructions. the movement of the webpages when scrolling is running slow and videos on ..... do not have as good of quality to it as it did on windows. so im assuming something is out of date or there are settings i need to adjust.
I have been upgrading Ubuntu as its new distributions are released every six months regularly since quite some time now. Is there a way I can find out which was the original installation version that I first installed after I formatted my disk. I mean as far as I remember I have been using this state of my Ubuntu since 8.04 and have been upgrading since then, but I am not sure.
I had installed Ubuntu 10.10 on a W7 OS, as a dual boot. I have removed Ubuntu, and now have that space as "free space". Between the original partition (c:) and the free space, there is a partition that contains the laptop mfg's factory image. I want to recover that free space back to the original c: partition. I was reading about GParted, but do not want to attempt anything until I have some expert advice.
