Ubuntu Installation :: Grub2 Configuration - Partition No Longer Shows Up In Chameleon?
Sep 24, 2010
boot up in to chameleon, lists only Mac OS X as a boot option. Reboot, load Ubuntu 10.4 install cd, get to a terminal, mount /dev/sda3 /mnt grub-install --force --root-directory=/mnt/ /dev/sda3
reboot, let chameleon come up, it sees both Mac OS X & Ubuntu partitions and I can boot to either or happily, now here is the problem... If I select linux and boot in to linux from chameleon, i am brought to the grub menu, where i can select the first choice which is normal ubuntu 10.4 and every thing is great... until I reboot and my linux partition no longer shows up in chameleon, as if tthe act of booting in to grub is changing something / deleting itself from the partition? and I have to do the whole thing over again. SO, not having to even go in to OS X, I'm not sure thats really the concerns more as I'm doing something wrong with grub.

i am dual booting windows 7 and ubuntu 10.4 lucid, i just reinstalled the Grub2 after my windows erased it, and now it boots into grub2 but i can only boot into my windows7 loader, ubuntu is not even listed as an option for me to boot into its just a bow with the win7 loader. How can i get the grub2 to load ubuntu back again? i followed the guide on this site to reinstall the Grub2 and set up the dual boot. [URL] edit: i can find plenty of info for getting windows back into grub, but none about getting ubuntu back

Awhile back, I made my desktop a hackintosh. The only way to boot it was Chameleon, which I was totally fine with because it looked nice. Currently, I removed OS X, and now only have Windows 7 and Ubuntu (10.04) installed. My gripe is that GRUB2 looks butt-ugly... it's still the basic white-text on black-background, without any graphics or anything. Is it possible to remove GRUB2 and replace it with Chameleon? Or maybe can Ubuntu start using Chameleon as the bootloader in future releases?

After having problems with grub2 and windows seven and being forced to reinstall both windows and Lubuntu, I got grub to work. So after some hours of work, everything is working fine. Today, I was trying to use windows again and windows is no longer listed on grub. What can I do to keep it permanently on the list?

I have two hard drives - (1) 80GB (2) 500GB: the 1st HD has 3 partitions (in that order) - Windows 7, Ubuntu 10.10 & Swap. the 2nd HD is for storage only, and has 2 partitions.
I did the following - I installed Windows 7 on the first partition of the 1st HD, it booted just fine. Then I installed Ubuntu 10.10 on the second partition of the 1st HD.
Windows 7 shows in the GRUB menu alongside with Ubuntu. Ubuntu boots just fine, but when I select Windows it simply restarts the computer and the GRUB menu shows again.

I decided to install the Ubuntu Netbook remix (9.10, I believe) on this extra IDE hard drive I had (my other three hard drives are SATA.) My primary hard drive contains a Windows XP, my second contains Windows 7, and my third SATA drive is just NTFS-formatted storage. I went through the installer and choose to format and install on my 40GB IDE hard drive, which it did. Then it finished and rebooted. It apparently decided to install the GRUB bootloader onto the primary hard drive (not the one it was installed on,) which was not my intention. The bootloader froze the boot of my computer and wouldn't work. (Stuck at loading GRUB.) I couldn't even get to the BIOS. So I pulled the plug on the primary hard drive and tried to boot again. I could get into Windows 7 just fine, but that was it. The problem, though, is that the CD drive (also SATA) no longer shows up in My Computer. Also, after changing the boot order and replugging in the former primary hard drive, it wouldn't show up, either. Nor would the IDE one (though I'm pretty sure that's because Windows doesn't understand the EXT (or whatever Ubuntu uses) file system.
Does anyone know why this occurred and how to get those drives to show up in Windows again? I don't really care to get the netbook remix working here, since this isn't even a laptop, it was just an experiment. Also, I'd love to know how to remove GRUB from my primary hard disk so that I can boot from it again.

I'm using Maverick Meerkat, 10.10, 64bit. I'm a pretty basic user but am trying my best to learn.
My background: I have a laptop on which I installed Win7 Ulimate on one partition. After installing Win7 I then installed Ubuntu on a separate partition. GRUB2 found both Win7 and Ubuntu perfectly. I could choose to boot into either one and the ability for GRUB2 to "remember" which OS I booted into last worked properly. I then did a kernel update a couple days ago via Ubuntu's Update Manager. After that, GRUB2 could no longer see Win7. I added a custom boot entry in /etc/grub.d/ so that Win7 would show up in GRUB2.
However once Win7 did show up in GRUB2 I kept having a problem with the Windows bootloader being missing. I used the Win7 Recovery DVD to get into Windows and then installed EasyBCD for Win in which I was able to create a Win7 boot entry and get the Win7 bootloader back. I set EasyBCD to skip the bootmenu so my current configuration now is that on bootup I see GRUB2, which shows Maverick Meerkat & Win7. If I select Win7 then Win7 loads via EasyBCD and it works fine.
The problem though is that GRUB2 does not auto-detect Win7 AND it no longer remembers the last OS that I booted into. I would rather not use EasyBCD if I can help it and would like to just use GRUB2 for everything.
My question is this: How can I get GRUB2 back to controlling Ubuntu & Win7 properly without the need for anything else in between. I have asked in the Freenode Ubuntu channel but haven't received any help besides "sudo update-grub" which I have done and it hasn't helped.

I need to debug upstart because it really doesn't start the jobs at system start that it should do. The upstart documentation says I need to add the kernel parameter "--verbose". Googling a bit further said I need to specify that parameter in the /etc/default/grub file. I found two lines where I can add it:GRUB_CMDLINE_LINUX and GRUB_CMDLINE_LINUX_DEFAULT.The grub documentation remains unclear about what is good for which. Shall I add my verbose parameter to the one or the other? What's the difference between the two anyway? The _DEFAULT currently contains "nomodeset" and the other is empty. Does one replace the other, or will one be appended to the other?I don't want to screw up my system with this because I only have SSH remote access to that server.

After installing windows XP,I did some googling to try to get ubuntu back,but seems messed something up. Right now,every time to boot system,I have to press "e" on first entry in boot menu,then press "e"s to do these two modifications to startup ubuntu corrently:
1,root (hd0,0)
----------------------------
(hd0,0) ===>> (hd0,4)
----------------------------
2,kernel /boot/... root=/dev/hd0 ro ..
[Code]....
2,then try to modify /boot/grub/grub.cfg: change all root (hd0,0) to (hd0,4)
(don't know and find where to change:"kernel /boot/... root=/dev/hd0 ro ..") and restart,thing is being same as before,so how can I get gr ub2 configured right?

I'm trying to install Ubuntu 10.10 on a brand new 500GB hard drive I just purchased and installed in my machine. I boot from the CD and instruct Ubuntu to install to this drive and tell it to "erase and use the entire disk" for this 500GB drive. After moving forward from that, I see it saying a message about creating an ext4 partition for root "/" and then shortly after the entire install dialogue goes away. All I am left with is the little circle cursors spinning round (mouse input still works) and the installation background. The HDD activity light was still on though. I gave it about 3 hours before I finally gave up and tried again.
When I tried again, I saw that it did create two partitions (root and swap) during the last attempt. The same thing happened, although now even mouse input isn't responding so my system is completely locked up. HDD activity remains active this time as well. Running Ubuntu from the CD works fine. The only problem I saw with it was when I ran gparted from the CD and tried to manually create a ext3 partition on my new disk drive. When I tried that, I ran into a similar occurrence (couldn't run any programs, eventually system locked up) and had to reboot.
I have a second hard disk but I have a lot of valuable data on that and don't want to mess around with it. It could be a hardware failure, but that seems unlikely to me as this is a brand new Seagate disk drive. I suppose I could try installing it on a spare partition on my other drive and see what happens, but other than that I'm out of ideas.

Im running Ubuntu 10.10 32 bit and Grub2. When running the update manager, I get the following message while it is configuring grub-pc: The Grub boot loader was previously installed to a disk that is no longer present, or whose normally unique identifier has been changed for some reason. It is important to make sure that the installed Grub stays in sync with other components such as grub.cfg...I change my hardware, including hard disks, frequently so that is likely the cause. My computer still boots but I like to fix this if possible. My disk partitions are:/dev/sda1/boot/dev/sda2/ /dev/sda3/home

I formatted 56 GBs of my hard disk space into fat32 and it seems that 27 gbs of it is used! Though direct checking from the volume itself shows nothing like this, gparted still insists 27 gbs are used.

after messing around with plymouth manager to try and get a decent boot screen(for the 3 weeks i've had 10.10 installed, it's just been a plain text bootup) it seemed to have removed my main boot option without recovery. i'm still able to boot into recovery and pull up my graphical environment but i can't seem to figure out how to get my normal boot option back.

drive is as follows:
NTFS Partition (Storage)
NTFS Partition (Win7)
Ubuntu
I am trying to put GRUB2 on the Ubuntu partition, but it will only let me pick the first two. If I pick the Ubuntu partition in the last dialog bix, it is listed as /dev/sda-1 I also have no idea why is says "-1", because the first two are fine at 1 and 2 respectively.

I just got a new hard drive and figured I might as well do an installation of Squeeze (and was previously using Lenny). That went fine, and then I decided that I should copy over my old Lenny installation to the new disk -- mostly to have a working backup without bothering to do a new installation on a partition of the new drive. My partition scheme was a smaller /boot partition and then a much larger / partition with everything else standard (and a much larger /data partition rather than storing everything under /home). So I copied /boot over to a new partition on the new disk, and the same with /. That was done from the Squeeze installation, so the Lenny install wasn't active at the time. I modified all the appropriate entries in /etc/fstab to use UUIDs rather than partition numbers and ran an update-grub.
It detected everything on the old and new disks without a problem. When I went to try and boot up the transferred Lenny installation, it hung on trying to activate the root file system (I've forgotten the exact messaging). Not entirely unexpected, mind you. I went and took a look at the grub.cfg file. It does list that the transferred Lenny is on partition sda8 (correct), it has the correct uuid for the boot partition... but it seems to be setting the root incorrectly. Specifically, the root is still set for the old disk (though in its new position of hd1 instead of hd0), and the "linux" line sets a root for the old device. Or more specifically, this is the menu entry I get, with a few // comments.
menuentry "Debian GNU/Linux, kernel 2.6.26-2-amd64 (on /dev/sda8)" {
insmod part_msdos
insmod ext2
set root='(hd1,msdos2)' // <------ This position is the *current* location of my old Lenny disk/partition
search --no-floppy --fs-uuid --set [the correct /boot UUID]
linux /vmlinuz-2.6.26-2-amd64 root=/dev/sda5 ro vga=795 // <----- that root=/dev/sda5 line is what it was on the old device.
initrd /initrd.img-2.6.26-2-amd64 }
The odd thing there is that it sets the root according to the *current* position of the old install disk (maybe some trickery with detecting the correct UUID before setting the root), but the "linux" line refers to the *old* partition. The two lines will never match up no matter what. Now if I edit grub.cfg manually, I can make it boot (and run) normally, as I've verified. For example, I made a couple manual changes to do this:
menuentry "Debian GNU/Linux, kernel 2.6.26-2-amd64 (on /dev/sda8)" {
insmod part_msdos
insmod ext2
set root='(hd0,msdos3)' // <----------- First hard drive, partition sda3 is where I put /boot
search --no-floppy --fs-uuid --set [the correct /boot UUID]
linux /vmlinuz-2.6.26-2-amd64 root=UUID=[the correct / UUID] ro vga=795 // <--- Changed it to the UUID here; could be /dev/sda8 instead
initrd /initrd.img-2.6.26-2-amd64 }
And that works perfectly, the installation works just fine. Of course, the problem is that those changes will/would be lost every time I run an update-grub. So my question, in a nutshell, is how can I configure things so that update-grub sets things properly to the new devices? Or in other words, where in the copied installation are the variables I need to change? I did note one thing odd -- the existence of a vga=795 line. For the new Squeeze installation, I'm using gfxpayload and there's no vga=anything line anywhere. My old installation, of course, had its own grub installation where I did use vga=795 to set the console resolution properly.
So my first guess was that update-grub (for Grub2) was pulling config information out of the Lenny /boot/grub folder (grub legacy). Unfortunately I tried several changes there and it made no difference. Then I deleted the entire /boot/grub folder entirely from the copied Lenny installation and ran update-grub again (the Squeeze grub version). It changed absolutely nothing. That's very confusing for me, since I have no clue where it could be getting vga=795 from, *except* the now-deleted Lenny /boot/grub folder. Where in the copied Lenny installation, I can change something to make it so that update-grub picks up the correct information?

I recently (for about the third time) HAD to re-install Windows 7. It just wouldn't boot and unfortunately I have some proprietary software that I need to use. Anyway, this is the first time I've had to do so since installing Lucid (64bit, fresh install). My problem now is, when I re-installed Grub2 (using the same methods that have previously worked flawlessly) to recover it after re-installing windows, only windows shows up in the grub menu, showing options to boot to Windows on sda1 and another to boot to Windows on sda2.
I grabed a "boot info script" from Rubi1200 and this is what I got..

Everything went fine but whenever I rebooted, Ubuntu 10.10 was not an option in the boot list. However, Windows shows up and boots just fine. I am currently tri booting (not sure if that's the correct term) Windows 7, Ubuntu 10.10, and OpenSuse each on a hard drive of their own. In the dolphin file manager I can still see all the files for Ubuntu so I know it was not partitioned over or deleted.

Ubuntu 10.04 fresh install on eee 900. I had previously tried Cairo-Dock and AWN (successfully but I like that DockbarX is integrated into the panel) I installed Dockbarx like so:
Code:
sudo add-apt-repository ppa:dockbar-main/ppa
sudo apt-get update
sudo apt-get install dockbarx
DockbarX was working.
Then I uninstalled Cairo and AWN with Synaptic.I got a notification of an error in the panel saying I had broken packages - see broken package filter to check it out.I can't find filters in Synaptic.Then I noticed DockbarX was empty (and I had pinned Firefox to it) So I tried uninstalling and reinstalling via terminal. No problems with that but when added it to the panel again it was still empty . I rebooted several times during these attempts.

I've used the startup-manager on my old laptop, also running ubuntu, to control the number of kernel options shown in the grub menu, as per this how-to:-[URL]see the last screenshot on the page. I've got a new laptop and am trying to do the same, but on the advanced tab I no longer have this "Limit the number of kernels in the boot menu" option, all I have is "Bootloader menu resolution" and [Create rescue floppy]. Is this because I am now running 64 bit or has this changed in 10.10 (I probably haven't looked at that on my old laptop since before 10.04)?

so after my upgrade to 10.04 I'm experiencing a puzzling problem with Grub2. It can load everything fine except for XP. I have XP on a separate partition, it is detecting fine and the grub.cfg file is created withou a problem when I the appropriate commands to update and upgrade grub. What happens is that I select Windows XP from the list and it goes to a black screen where a cursor in the top left corner blinks 3-5 times and then immediately kicks me back to the Grub menu. I can do this forever but the grub menu just gets reloaded every time. Any ideas?
Here is the windows portion of my Grub.cfg:
### BEGIN /etc/grub.d/30_os-prober ###
menuentry "Microsoft Windows XP Professional (on /dev/sda2)" {
insmod ntfs
[code]...
Here is my boot.ini on the ntfs partion I am trying to boot into
[boot loader]

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?

Transmission used to show space remaining on the drive you choose in the add window. Now it doesn't. Was this removed? I LOVED that convenience of not having to go to a separate file browser or terminal to show space. I tried posting at Transmissions forums but it's been 4 days with only 7 views and no reason to bump b/c the forum is so slow I'm still on the front page.
