Looks like 10.10 will have grub2 and so the ability to boot on efi system. I have a macbook pro 6.2.Will maverick install on this machine as normal dual boot with no need of refit support?
View 5 RepliesBasically, I cannot load 10.04 without 'nomodeset' being set in the boot line. Is there a way to make GRUB2 append this to every entry automatically?
Can I change the entry I have now somehow? Not a fan of GRUB2 so far here.
I wanted to update to the latest ubuntu but was short a couple of gigs in my linux partition. So i created a Gparted Live bootdisk and repartitioned my hard drive: i took 5 gigs from my mac os partition and moved it to the linux partition...
After that i could no longer see any boot option aside from Mac OS when starting the computer with the option key held down. So i thought maybe rEFIt might be the solution (i have no idea what i'm doing really) and installed refit. I'm not sure what that achieved - i can still only see one boot option (mac os - although it's now named 'refit'...)

I modified SnowLeopard to install on mbr disk format. How can I chainload to the bootloader on the OS X partition using GRUB2. The autodetected entry MAC OS X put in by ubiquity on installing ubuntu doesn't work. In grub legacy I just added an entry with root() and chainload and it worked. How can I achieve this with grub2?The computer is an Intel Mac. I am unable to install Windows 7 on a GUID disk (without using bootcamp).
View 3 Replies View RelatedI've read the various Grub2 posts and even the guide, but unfortunately for me I can't seem to come up with an answer to my problem. I installed Ubuntu 9.10 on a new hard drive on a friends laptop, but I have problems with the system hanging on the Grub2 bootup.I'll post the screen

If I hold down the left shift and then press E to edit and remove the search --no floppy line entirely then press ctrl-x the system boots just fine. I then opened up a terminal and did sudo update-grub to try that but it didn't fix it. Is this a problem in my bios looking for a floppy, I tried with the boot from floppy enabled and disabled (but always as the 3rd boot option) the floppy is not installed. Is there anyway to edit the file and save it so it will boot up? I was trying to research that and could not come up with it.
As a long time Red Hat/Fedora user, I'm quite new to the Ubuntu/Debian culture, and/or, to the Grub2 specific behavior.I'd like to see Grub2 system selection menu at every boot time even if I only have a single operating system, Ubuntu 9.10, on my hard drive. What should I do fot this purpose?
View 1 Replies View RelatedBeen using Linux for many many years but Grub2 is annoying the heck out of me at the moment.
My home desktop PC is set up as follows:
/dev/sda � 40GB 10k Raptor with Ubuntu 10.10 installed
/dev/sdb � 500GB HDD formatted to ext4
/dev/sdc � 500GB HDD split up as follows:
/dev/sdc1 � 80gb NTFS partition with Win7 installed
/dev/sdc1 � Remaining drive space NTFS but nothing on it yet
Grub2 refuses to detect that Windows is installed on the 3rd HDD. I've googled and spent hours trying all sorts of things to get it to detect it and add it to my boot menu.
If I disconnect all drives except the Windows drive it boots up straight into Win7, so it's healthy and happy. (as healthy and happy as Windows can be, I need it for work purposes only!)
Does anyone have any tips on what would be the best method to force grub to realise that Windows is sitting there?
As far as I understand, the Win7 partition should be (hd2,1) � does that sound right to you?
I haven't tried booting off an Ubuntu CD and re-installing grub, since I can get into Linux and all the guides seem to be about how to restore grub after a Windows install eats it...
I recently installed Ubuntu Netbook Remix (10.04) on my brother's Acer Aspire One (751h) netbook, set up to dual boot with XP Professional. The initial install was successful, with both OS's booting correctly. However, after a series of updates and module builds (this machine has the Poulsbo chipset, still somewhat of a mess), Grub2 is now unable to boot XP, displaying the error "Operating system not found."
To be clear, grub works properly (aside from not booting XP), so the MBR is intact, although I've rerun grub-install to be safe. Restoring the windows MBR (using testdisk) boots XP happily, but of course ignores the ubuntu installation. I also had testdisk rebuild the NTFS boot sector, to no change - grub still doesn't work, the windows MBR does. Using the grub console, I can "root (hd0,1)" and see files on the XP partition, but "chainloader +1; boot" again fails with the same error. The ubuntu install can likewise mount the NTFS partition with no problems.
Given the fact that switching the MBR fixes the issue, I'm suspecting a Grub2 configuration problem. However, the simplicity of "root (hd0,1); chainloader +1; boot" leaves me stumped as to what that could be. Also, the error text "Operating system not found" is suspiciously identical to my BIOS's error message when attempting to boot from a non-bootable medium (as I found out while attempting to make a bootable usb stick with my mac).
I've been using Ubuntu on my PCs and laptops for quite a while. Recently, I've been allocated a Mac for use in my lab. It is a PowerPC G5 running on Mac OS X 10.4.11. I've installed Ubuntu on one of the two hard disks available, the other one being the disk which Mac is installed in. There was no problems with the installation, but I cannot get Ubuntu to boot. Basically, when I restart the system, it boots into Mac straight away.
There is no boot loader or GRUB. I've tried holding down the options key when the system starts, but for some unknown reasons, the monitor cannot find a signal, so I cannot see what is going on. The monitor can only pick up a signal after Mac starts to boot (or, when I was installing Ubuntu, after the virtual Ubuntu has loaded). Am I suppose to expect GRUB or some other boot loader?
I have been frustrated attempting to get Grub2 to boot a Debian Live system from hard disk. Have set aside a 4gb partition /dev/sda1 to contain the Debian Live and some other recovery tools. I actually have them all working from a 4gb USB stick successfully, but getting it to work on my HDD has proved challenging. On USB, I have PartedMagic, Gparted, Grml, and of course my standard 6.01 Squeeze. I have also managed to get the Debian Live booting from that USB stick. Very slick.
However, I can NOT get Debian Live to boot from my HDD; altho all of the others above boot fine. Have tried it two ways - one using an iSO image, which is how it is done on my USB stick. The other attempt is to copy the entire contents of the ISO to a directory.
Here are my directory structures:
debian_live_gnome_squeeze_i386- contains the following: debian-live-6.0.1-i386-gnome-desktop.iso initrd.gz initrd.img vmlinuz which is how it is laid out on my USB stick debian_live - contains the files from the ISO image The error I get is something like "panic unable to find live filesystem" My grub.cfg snippet for the two methods I have tried - the 2nd menuentry is similar to how it works on the USB stick.
menuentry "Debian 6.01 Live (on /dev/sda1)" {
insmod part_msdos
insmod ext2
set root=(hd0,msdos1)
[code]....
Probly don't really need to get it working since PartedMagic can do almost everything I need for recovery and I can use the USB for reinstall or whatever else.
I currently have an old powermac 7220/200 with all ehe origanl stuff except for the hard drive which is now a slightly larger one. I was wondering if it was possible to set up a ubuntu installation on it using a 20g hard drive (I have got one of these going on a 486 running win98, just) and be able to run mac os as a dual boot system, possibly with 9.1 and the origanal mac os that come with it? Unfortunantly I cannot connect this computer to any internet even if I had a card that was compatible with mac os.

View 3 Replies View RelatedI previously had Ubuntu installed on my MBR. I deleted that partition (32 GB), resized my Mac partition back up to (250 GB), and then reduced it to 200 GB and created a new one with 50 GB via BootCamp to install Windows 7 from a DVD that I burnt (I got a Windows executable from MSDNAA that I used with Wine to obtain the ISO image. Insert rant about having to download Windows with a Windows executable here.).
I've tried burning two different DVDs. I used Burn on my Mac to burn a data DVD+R with the HFS+ and Joliet filesystems (I think) and then tried again with the ISO9660 and UDF filesystems. The latter has not shown any signs of working besides mounting on OS X. The first DVD would not boot whenever I held 'C' down at time of boot. So I went into BootCamp and clicked "Start Installation". It restarted my computer and this is where the real confusion comes up. I think that it tried booting via the empty partition. The reason I say this is that there are remnants of GRUB and when I boot, I get a screen that says this: error: unknown filesystemrub rescue>
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)?
View 2 Replies View RelatedAnybody recently succeded in installing GRUB2 on Mac OSX partitions? I have to compile in un Fedora/Ubuntu/Gentoo. It work, but once back in OS X, I get this error:
./grub-mkimage -d . -o grub.efi part_gpt hfsplus fat ext2 etx3 ext4 normal sh chain boot configfile linux -bash: ./grub-mkimage: cannot execute binary file
I tried to build it in Ubuntu 8.04, gentoo and Fedora Rawhide, all fail with the same error. Look like the binary compatiility between OSX and Linux is broken in Leopard. I would love to have a faster boot, it take half a minute to get to grub, using Grub2 with EFI would take 3 seconds. As I don't need bios emulation, Fedora would also run faster. Anybody have a compiled and working Grub2? Is there a better way to use Grub2 with EFI? A working one if possible

I'm not the world's biggest fan of rEFIt to be perfectly honest. It doesn't allow me to customize the menu, set a default, etc. I'd rather boot exclusively using grub-efi. Not just that, I'd prefer to be able to do so without needing an hfs+ volume to bless it onto. edit: I can now see that Elv117 has asked this recently. I shall leave this post here in the hopes that someone knowledgable runs across it and not the one further down the page. Also, I'll probably try working through the tutorial to see if I can manage it. I need to evaluate if I really need OS X at all on my MacBook. I think it would be neat to have GPT/Grub2/MacOSX/Ubuntu/Win7 working properly, the way a "modern" computer ought to. Reverting to MBR is just throwing in the towel.
View 7 Replies View RelatedI've been running Jaunty on my drive D: with XP Professional on a separate partition. Today I formatted a different drive, C:, which had previously shown up in GRUB as XP Home Edition, and placed a new XP Professional on it.
Now when both HDs are connected, C: boots without GRUB starting, and when I disconnect C:, the GRUB on D: starts, but cannot find the XP Professional NTDLR. I don't want to take up too much of anyone's time here with this; I'm mostly just curious as to what may have happened?
I have a macbook pro 4,1 which does not have a functioning cd drive. I'm trying to install ubuntu by loop-booting an iso from the hard drive (or a usb drive, or using the netbook kernel, or the files from a live usb, or anything really) It will not boot off of usb drives. I've read that this is an issue with the firmware of these machines and there's not much I can do about it. rEFIt sees the usb drive, but the macbook complains there is no OS when it attempts to boot from it.
I've installed grub2 locally by dropping a home-built grub.efi (And modules and whatnot) in /efi/grub. This lets me pick grub from the refit menu, and grub will correctly load up a grub.cfg, and I can get into a grub shell and browse around, pick kernels etc. The problem comes when I try to boot anything. I've tried the netboot kernel and initrd, I've tried loop booting an ISO, I've tried copying a live usb to disk and booting that kernel, but no dice. any way I go about it, I can select the kernel and initrd, and that appears to work fine. Grub gives me some correct-looking info messages about the kernel and initrd that I just loaded, but then when I try to actually boot (i.e. with the boot command), nothing happens, I just get a cursor that sits there and does nothing.
I've tried with everything (the iso, the kernel and initrd) on the first partition, on other partitions, with different filesystems (both hfs+ and fat32) all to no avail, and all with the same symptoms, grub just sits there after the kernel and initrd are loaded and does nothing. I'm wondering if there's some kernel arguments I need to make things happen on the macbook or some other magic like that. This is a pretty non-ordinary boot setup so it's not terribly easy to find info about it.

I wanted to experiment with Fedora 14.
The machine has Windows XP and Ubuntu 9.10.
Before today when I turned the machine on there was a black screen with many Linux kernels to choose from and Windows.
I created another for Fedora and installed it on there - the Ubuntu root partition is still there.
When I boot now, there is a blue Fedora screen with just it and Windows.
To make matters worse Fedora doesn't work with my graphics card (Matrox). I would like to get Fedora working but still want to have the ability to use Ubuntu again.
What do I need to change to be able to boot into Ubuntu again and how do I do it?
I think I've got myself into a bit of a situation. I've got 3 operating systems across 2 hard drives, and i need to get them loading properly.
I have my primary ubuntu 8.10 install @
/dev/sda1
I have a new Windows XP install @
/dev/sdb2
And I have a new install of Ubuntu 9.10 @
/dev/sdb3
I'd like to be able to selectively boot into all 3 until I can return my current 8.10 install. Can someone show me how to get my /boot/grub/menu.lst file in order?
I have a laptop with Windows 7, and about a week ago I installed Ubuntu 10.10 64-bit via LiLi USB creator. Worked beautifully, but I was having some issues with the brightness controls so I decided to get cute and upgrade to 11.04. So I downloaded the beta2 and used LiLi to make the USB (unsupported for that version of course) which used the same parameters as 10.10. I then tried to do a fresh install over the partition I had set aside for Ubuntu and had 10.10 installed on (~80 GB).
So in the installation itself, something got majorly screwed, and the entire system froze. Next thing I knew, I was rebooting and got the Grub Rescue prompt and no ability to load into either my old Ubuntu 10.10 or my new failed 11.04, or of course my Windows 7 partition either. The partition is obviously there, and as I only have one PC in my house, with no Windows 7 recovery discs, I currently cannot fix the mbr to just get my Windows back. I can of course get this in a couple days, but I'd like to be able to fix this without going to my parents.

Those are my partitions. /dev/sda3 is my Windows Partition, which I want to boot from. Only problem is, I'm not really sure where the computer is looking to find the boot record. I think it's from my fubarred /dev/sda4 partition which means it's basically looking nowhere. So I can't modify it to point to my Windows so I can just get back there.

View 9 Replies View RelatedI 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:-

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.

I've set up a triple boot system (Ubuntu Karmic, Windows Vista and OSX86 -- a patched OS X which works on a PC) on a Dell 9200 (C2D 2.13 GHz, 4GB RAM, nVidia G210). I sue Grub2 as the bootloader and update-grub picks up OS X and it boots without any problem.
However, although when booting OS X using its own Darwin bootloader, I can apply the boot option "Graphics Mode"="1680x1050x32" to ensure that I get the screen resolution that I want, when OS X boots from Grub2, the only resolution available is 1024x768 which is disappointing. I have tried adding gfxmode=1650x1050x32 to the OS X section of /boot/grub/grub.cfg in Ubuntu but this does nothing.
The screen will show a blinking cursor for a few seconds. The keyboard works and a signal is found for the speakers. Then the 'Ubuntu' loading screen will show but at this point the screen would freeze and the keyboard will cease to function. At this point I have to reboot from the on/off switch. It can take several attempts before the desktop will load, or if I'm lucky, it'll load up first time. I've had this problem since 9.10. I'm not quite sure why it's taken me this long to attempt to sort it out.
