Ubuntu :: Re-installed Grub2 But It Wouldn't Boot?
Sep 21, 2010
I have a 2 hard drive laptop. I have Mac OSX on /dev/sda and 64 bit Ubuntu on /dev/sdb. (I did have 32 bit Ubuntu on /dev/sda as well, but I have deleted that). So with the intention of deleting the 32 bit version and to make sure the 64 bit version on sdb still booted I re-installed grub2 to sdb before I deleted the 32 bit installation from sda. Sadly it wouldn't boot. It gave me the "no such partition - grub rescue" message. So I booted up the live cd and re-installed grub2 to sdb again, just to make sure. It ran ok but on reboot got the same message as before.So I booted up the live cd again and installed grub2 to sda and now it boots fine.I presume that the bios is looking at the first hard drive and if it finds nothing there it just gives up - not looking at the second drive at all. Is this normal on a 2 drive system? Unfortunately as it's a Sony Vaio the bios is almost completely locked so I suspect I cannot change it.
I am trying to dual-boot windows xp and ubuntu 8.04LTS from two separate hard drives, on a compaq d510 evo SFF. With research, the best way to do that seemed to be to upgrade to Grub 2 and all would be well...not so much. I installed each OS with the other hard drive removed, fyi. I believe that this tells me that I SHOULD be able to boot off either drive, if I could get Grub 2 to recognize...

I have also tried adding the proper code to the 40 custom file, and while I could at least get it to acknowledge my changes, I couldn't seem to find the magic code to get it right.... The other thing I tried was adding GRUB_DISABLE_OS_PROBER=false to /etc/default/grub and last but not least, here is my results.txt from the boot info script. I also tried uninstalling/reinstalling grub 2, perhaps I created issues there?

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.
I tried to install 11.3 on my acer aspire 7530 notebook to have dual boot with xp.
I made 4 partitions: one for xp, and the three for linux were made automatically.Before installation I got the warning that the partition wasn't entirely below 128 gb, I installed anyway to give it a try.
The installation froze at 92% and after the laptop wouldn't boot.
Now I've formatted the hard disk and installed windows on a partition leaving a free un formatted partition of 100 gb.
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.

I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?
- Im using 3 different USB keys, a 1gb, another 1gb, and a 4gb, the 4gb being the newest, and one of the 1gb might be early usb2.0. - My motherboard has options in the bios for both USB HDD and FDD, and even USB ZIP drives. I set the boot order to USB FDD, then USB HDD, then HDD. - I am trying to get Damn Small Linux 4.4.9 to work. - When the screen after the motherboard logo is loading, it recognizes both my USB HDD and the FDD, displaying both names for each, and their capacity. But it just then skips to the dual boot options for my 160GB OS HDD. - Legacy USB is enabled - I'm using the actual ports on the mother board, not the front pannel ports.
Background information: The hardware is an iMac. I had Ubuntu 10.10 and Mac OS X.... Something. That part doesn't matter. The Mac OS is still working....
So... I had everything set up, and I was happy to start my life getting used to Linux and learning all about a new operating system and how to use it and whatnot. I wanted to change my username, though, because when I was setting up my account, I didn't have a mouse and weird things were happening when I tried to change my username at the time. So I looked up on the internet (a very wonderful thing) how to change my username. I found that it required root access. I knew that I shouldn't have tried it because I was, and still am, so inexperienced. Then I went against my better judgement and f'ed up the system. Happy days, right? I couldn't do anything on Ubuntu anymore at that point. I had kind of wanted to do a clean install of Ubuntu at that point anyway, so that's what I decided to do. The mistake came when I decided to try to do it on my own instead of using the wonderful invention that is the internet to figure it out. So I went onto my Mac OS to erase the partitions I was using for Linux. So everything was fine until I tried to boot from my USB to reinstall Ubuntu. It keeps taking me to the command line that says "error: unknown filesystem. [return] grub rescue>" The exact same thing happens when I try to boot from the hard drive. I was really curious why it's not actually booting anything from the USB drive, because I shouldn't need the hard drive to do that, correct? I tested the USB on my Windows netbook, and it worked as it was supposed to work. I was able to try Ubuntu just fine. Then I put Ubuntu 10.04 on my flash drive. It also wouldn't boot on my Mac. Does anybody have any advice for how to get Linux working on my Mac again? I'm really sick of Mac OS and would prefer using Linux.
I've spent a frustrating afternoon trying to install Xubuntu 10.04 x64. I had already installed Win7 Pro 64, and have been attempting to install on a separate hard drive. It wouldn't even boot into Xubuntu install. Figured a bad burn on the Cd so I reburned the image I had down loaded using Ktorrent. It wouldn't boot either. I swapped out the DVD burner. Still no go. Redownloaded using Ktorrent including the torrent. Wouldn't boot into the installer.
I did a fresh burn. Still it wouldn't boot to the installer. I then downloaded Xubuntu again but from a mirror and not using Ktorrent. Good MD5SUM. Burned it again on another computer. Still wouldn't boot into the installer. I burned a copy of Kubuntu 10.04 x64 and it installed with no difficulty. I've installed Xubuntu 10.04 x86 several times on other computers win no difficulty. But I have 8 Gb of RAM on this machine and want to use Xubuntu 64.
I tried burning straight to the CD after download Ubuntu. It wouldn't boot from the CD. Can anyone explain the steps I need to reproduce to make this happen?
I used a cd version of ubuntu 10.4 but my laptop wouldn't boot.I thought of installing the previous version of ubuntu and then upgrade it.I used ubuntu 9 and it worked perfectly. But when the upgrade finished and my pc restarted it showed this message [1.007098] Disabling IRQ#4
I tried to boot from CD for demo mode (9.10) but my XP machine wouldn't do it. I opened CD from My Computer and a selection window opened. Choices were to reboot to demo, Install to Windows or Help with Boot. I selected Help with Boot and a boot program was downloaded and installed (I think to drive C: (XP)). When I restarted, a new boot window opened giving me a choice to boot to XP or Ubuntu (9.10) and I chose Ubuntu. Instead of opening for demo it went to full install and I aborted the procedure, went to add/remove programs and uninstalled Ubuntu. Now when I restart I still get the boot selection window, Any suggestions as how to remove the boot program? Can't find it.
So, a little backstory. For christmas I got a new laptop with Windows 7, and while Win7 is a good operating system, I wanted to try Ubuntu and see which one I liked better. I installed the 32 bit version, because I understand people run 32 bit Ubuntu on 64 bit machines with out problems. For the first few days, everything was going amazing and I was pretty much using only Ubuntu (I had a dual boot with WIn7). One day, I opened my lid to find that the log in screen wouldn't appear, so I restarted.
I wish I could remember what error I got, but everytime grub tried to load Ubuntu, it wouldn't load, it just gave me some error (it may have been a kernel panic, not sure). So I went into windows, burned a windows repair disc, and fixed the MBR to be the windows boot loader instead of grub, then deleted the Ubuntu partition. Shortly after, I tried the 64 bit Ubuntu installation, and it wouldn't even boot up after the first boot (unfortunately, can't remember the error I got then either). So I repeated the MBR fix for Windows, and just stuck with Windows for a while. However, a new problem arose. Every now and then (and in time, more frequently) everything would freeze, for 1 to 2 seconds.
It couldn't have been my RAM or anything, the computer was blazing fast when I got it. The windows boot also took much much longer than usual, until it just wouldn't boot at all. I had my father (who's much more knowledgeable at computers) to do something, and he loaded into an earlier recovery partition ran a program called CCleaner, which supposedly fixed it. However, the problem was still there, and it got worse. I tried CHKDSK, it didn't do anything. The random freeze ups kept happing more frequently and became more and more bothersome. Eventually my computer just wouldn't boot up, it would just be a blank screen after the 'Toshiba' logo.
I eventually called Toshiba and they said that I apparently deleted the original recovery partition, and needed a Windows install disc, which I don't have so I have to buy one. Until then, I decided to just do a complete install of Ubuntu (64 bit), since I figured if I just did a complete fresh install removing everything, it would fix it. Well, turns out it had the same freeze up problem. I then tried a clean install of 32 bit Ubuntu. No luck, still periodical freeze ups, sometimes if the freeze ups are longer the screen will go grey. Before all this mess Ubuntu ran perfectly. I'm fearing that it may be my hard drive that's the problem, but I'm not entirely sure. So, is there anything I can do to restore my laptop to full health with out buying a new hard drive? Unless the hard drive isn't the problem, but I don't see what else is. EDIT: I tried memtest. Here are the results: It says 'Pass complete, no errors'. What do you guys think?
I had installed Fedora 13 on an unused partition of my ATA hard-drive yesterday. The primary OS here was Windows Vista.
Anyway, everything was working fne for coupla hours after which I had to restart F13 for some reason. This is when all the trouble began ..
Fedora wouldn't boot cause of some "power issues" - there were none. Windows Vista wouldn't boot because "BootMGR was missing"
I figured if I removed Fedora using the live CD - format the partition, it would help. It didn't. Well, atleast the partition got formatted. I tried re-installing F13 from the live CD but it doesn't finish the process - saying a command, something to do with 'shutdown' is not valid.
I tried repairing Vista from the Installation DVD but it is unable to do so.
Right now, on rebooting the computing, I enter the 'grub' console. I tried using grub commands to boot "Windows" from the (hd0,0) partition like thus,
Code: grub> rootnoverify (hd0,0) grub> makeactive grub> chainloader +1 grub> boot But it still maintains that "BootMGR is missing" .
When I was installing the last kernel update, the system informed me that I had to remove the kernel that was 2 back. The new kernel wouldn't boot and I reported the bug via bugzilla. I got a response within a day that a new kernel had been posted on koji and I was aked to try and see if it resolved my problem. When I installed it I was again forced to remove the kernel that was 2 back. This left me with only 1 known working kernel and if this new one hadn't worked, another attempt would have put me out of business.
What enforces this apparent rule of only 3 kernels. I upgraded from F10 to F13. F10 would let me keep as many kernels as I wanted and I could clean up old ones when appropriate. How can I disable this? I really need to be able to keep several kernels on the system at any given time.
I have Intel Pentium3 motherboard model 845GVSR with 40 GB Hard Drive, DVD/CD ROM and 4 USB slots but no Floppy Drive.My PC was working fine until I deleted the contents of hard drive accidentally using trial version of killer software.I ried to install Linux by making a boot-able CD, but it did not work.Then i tried to make a boot-able USB using Universal Notebook Installer, it did not work either. I just get the Error " Error loading operating system.Then I tried a free software from net by the name James Format Tools - DOS on USB. Using this computer did boot but DOS did not install and I got the error message "invalid drive specification".I understand that now I will have to write boot sector afresh and will have to Format the hard drive,, but how to do this as all my attempts to get to the hard drive failed
I got wireless printing working on my mom's computer... Then when I upgraded the laptop to 11.04 it wouldn't boot properly. It shows the Ubuntu splash and then switches to a console where I can see services starting and stopping. It freezes when it's going through this section of startup. I rebooted and started the machine in recovery mode, then selected low-graphics from the list. It works in low-graphics mode in Ubuntu Classic (my mom doesn't want Unity so I set Classic as the default)
After discovering that the "/boot" partition did not end on a cylinder boundary, I booted back up into the alternate cd, re-partitioned everything and re-installed.It worked fine after thatI can't seem to get Grub2 Installed.
I'm playing with my hard drive partitions and trying out different O/S versions so I want Grub2 to be aware of them on its boot menu. Currently I'm using the maintainer's version of Grub2 that came with karmic. Do I have to do a re-install of Grub2 or is there a makefile I can use? Specific commands that I would need be nice.
I'm trying to find out which partition grub2 is installed in. Is there a command for this, as I suspect that I may have told it to install to the wrong partition during the upgrade from Karmic to Lucid, and now, I suspect that I've crippled the boot sector for my vista installation
I have a dual boot system: windows xp and suse(10.2). I had to reinstall windows(again). When I tried to use the installer, it kept reseting my partitions to 500gb+ to linux. Nothing I tried would let me put it to the way it was(50gb to linux). Repair install failed. Update wouldn't work. MSwindows in the grub boot menu disappeared. I tried reinstalling suse. The installer blocked any attempt by me to put the partitions back to normal. How do reset the windows and linux partitions(850gb windows, 50gb to suse linux)?
Is there a way to install grub2 from a linux live cd when linux isn't installed on any of the partitions? I'm setting up a multiboot partition for someone and I don't want to install linux anywhere on the computer since hard drive space is running short.
I am going to setup a new Ubuntu 10.04 using RAID 1 soon. Installation will be via the alternate CD. Older distributions required manually installing Grub to the second drive, to boot if the first drive fails. I found different statements about how this is handled since 9.10.e.g.
Quote:
Install GRUB boot-loader on second drive (this step is not need if you use Ubuntu 9.10)
or
Quote:
installing GRUB to second hard drive depending on your distribution
> grub-install /dev/md0 or > grub-install /dev/sda > grub-install /dev/sdb
is Grub2 automatically installed in all RAID drives using alternate CD 10.04 like executing sort of "grub-nstall /dev/md0" during the installation ?
I am using Ubuntu 10.04.1 and I run it 24 hours a day. Recently one morning I went to my laptop and opened the screen but the login screen wouldn't appear. Anytime the cursor appeared, HDD activity would go to 100%. I'm assuming this because the HDD light on my laptop was permanently on. So I made the dumb decision of just holding the power button down and turning it off. When I turned it back on, I noticed it came to a command prompt type screen listing "initramfs" at the bottom apparently wanting me to input a command. I did a lot of research and couldn't find much of anything that would help me. I read about GRUB, superblocks, fsck, e2fsck, etc.. . I tried all of those and nothing has worked so far. Any ideas? I did notice one thing. When I went into the actual install with the livecd, it told me the drive was /dev/sda5, but in Disk Utility on the livecd, it told me it was /dev/sda1
I recently downloaded grub2 source code for my F13 installation and it compiled and installed perfectly, but when I rebooted nothing had happened and grub was still version .97. Is there something I didn't do?
I recently got a netbook and setup as dual boot between win7 starter and 9.10 (64bit). Win 7 starter is not impressive so i want to nuke it and give the space all to my /USR partion. I am comfortable working with Gparted and assume that i can launch using my gparted live usb and delete the windows partion and then resize the /usr partion.
what changes do i need to make w/ Grub2? I would prefer not to see the Grub menu at all and have it load right the main kernel if possible. Also, if this is possible is there a way to get to the Grub menu during boot should i need to select a different kernel?
After installing karmic with Grub2 I am unable to boot into Archlinux partition. Grub2 has removed the last line of the Archlinux boot stanza! It used to read:-
[Code]....
Following the Grub2 tutorials I have tried editing /etc/grub.d/40_custom as follows:-
[Code]....
But no luck. Only way into Archlinux is to get into the edit shell and manually add the missing line and remove other stuff not needed. I have spent hours trying to resolve this issue and I am fairly p----d off
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'm as big a fan of Linux as Linus Torvalds himself but it's things like this that help to keep Linux from becoming mainstream. I mean, how would I ever explain the need for the following procedure to a non-techie type, recent or prospective Ubuntu convert? The following is not a question, as I have finally resolved the issue but is more of a rant, I guess you could say. The reasons that I decided to post it are:
1) To hopefully help someone else experiencing this issue.
2) To point out the need for significant improvement in the area of editing partitions under Ubuntu Linux. 3) To vent my spleen.
