General :: How To Remove GRUB2 & Ubuntu From MacBook Pro With Windows 7?
Jul 17, 2010
They finally got the MCP89 kernel patch finalized and released as a Ubuntu DVD in the daily build of Lucid Lynx (good job!). I tried it, but even after following Ubuntu's Wiki-guide to fix various problems, a lot of my Mac's functionality broke and I don't want to take up that battle yet (of trying to get everything to work perfectly {I'm a perfectionist}).So I want to remove Ubuntu and GRUB2 from my system. But even with some experience with problems like these, I'm in the ultimate pickle. OS X uses the GUID Partition scheme and EFI, whilst bootcamp has a BIOS/MBR emulator to run Windows. I installed the GRUB bootloader to the MBR (I think {In "/dev/sda" during the install}). I use rEFIt to chainload into GRUB2 to boot Ubuntu, and I want to remove that icon, return to booting Windows 7 using it's own bootloader, and restore the GB's that Ubuntu took back to the Windows 7 partition.
I'm lost and (for the first time in a while) WAY over my head. I have no experience with EFI/GUID. (I just got my first Mac a month ago)

I've been dabbling into linux by installing Wubi on my main computer, out of ease to install, but I use windows to do many things I'm not sure if I could do as easily in linux. Anyway, I had a macbook before I got my new main computer, and have been wondering if I can install linux on my macbook to test out other distros without potentially endangering my main computer (out of complete idiocy on my part, of course). Is this possible? Is there any specific "guide" out to do this?

I have Suse 11.2 and Win XP running from a Grub2 boot loader. I want to remove Win XP from the machine.What is the best way to do that? Is it safe just to replace the partition that Win XP is on with a Linux partition?
Assuming that is OK, will Grub then boot OK, and recognise automatically that the Win XP OS is gone, or do I also need to update the Grub configuration manually? I did try looking at the Grub Wiki, but I find it very hard to use

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 have a 3 year macbook with Windows 7 installed as 40gb and OS X as 40gb (80gb HD). I want to remove OS X as Im at the limit of 40gb on Windows and I have not logged on to Mac OS X since installed Win7 (dont flame me).
So I want to delete OS X partition and expand my win partition to 80gb BUT I still would like to be able to regularly (once a week/month) backup my Windows 7 partition - its took a while to setup everything up right - not just docs and programs - so when the hard drive dies I want to be able to restore the partition and boot away, (the daily volatile bits I can pull down from dropbox and project from soure control). With Mac OS X I could use Winclone - and this worked flawless last time the HD failed with XP but with the absence of OS X I will need something else.
Im thinking can I use a Linux Live boot CD along with an external USB hard drive. Boot from CD and then dd? the partition to the USB?
What linux distro live CD should I use? I say dd as if I know what am taking about (I dont) is this the best way to backup a partition (when it will be restored to same hardware as bootable) ? What command?

I just installed CrunchBang Linux and it's great! But I can't boot into windows anymore. I'm sure it didn't delete my Windows partition-it's mounted. My linux partition is /dev/sda1 Windows is /dev/sda2
Code:
sudo update-grub
Found linux image: ....
Found initrd image: ....
Found linux image: ....
Found initrd image: ....
done
how I can get Windows to reappear? I've had bad luck with Grub in the past and I don't want to fight it on my own...

Sda2 is normally xp windows, but it installs a wrong partition type, and when I apply the mbr.bin, it works again with grub2, nope, it says:
Code:
autochk not found
Code:
# fdisk -l
Disk /dev/sda: 60.0 GB, 60011642880 bytes
255 heads, 63 sectors/track, 7296 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0005c9c1 .....
If I put the mbrofxp.bin (bs=512 count=1), then xp boots well but no grub2 so no linux

I had Windows 7 installed on my system, then I installed Debian testing with grub2 as its boot manager.Initially I couldn't see windows entry in grub at all, so I ran:aptitude install os-prober kcpuload update-grub Now I can see the entry, but when I select it I get only Win7 system restore, instead of the the real thing. Any ides how to make it work?
EDIT: I tried the suggested approach to add a new file to /etc/grub.d, which generated an entry in grub.cfg, but it does not appear in the grub menu on boot :(
I have this:
grzes:/home/ga# cat /etc/grub.d/11_Windows
#! /bin/sh -e
echo Adding Windows >&2
cat << EOF
menuentry "Windows 7″ {

It's quite easy to change the default boot entry through etc/default/grub. However, this only allows for the first entry to be changed. I want to be able to move all the entries in any order I like. What is the best/easiest way to do this?

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?

I followed the Grub 2 Basics steps to remove Grub 2 kernel listings.
However I'm stuck with 3 older versions that was completely_removed from Synaptic (kernel/headers/generic), but remain in grub.cfg.

Here is my current grub.cfg:

I considered changing permissions for grub.cfg, but update-grub and new kernels will revert my changes.

So I have my netbook triple-booted with Windows XP, vanilla Ubuntu, and Kubuntu Netbook (Installed in that order).
I however would love to remove Kubuntu Netbook from my computer, but unfortunately, since I installed it last, it is the Linux OS that owns the current default GRUB files that the BIOS reads first.
Can someone please tell me what to do to remove the Kubuntu partition and restore the default GRUB to my vanilla Ubuntu so I can still use my computer? I've done this incorrectly before and freaked myself out because whilst trying to access the GRUB, my computer couldn't find it because the partition that the files were originally on was gone. Haha. I don't even know how it got fixed.

I am trying to triple boot osx, win7 and ubuntu 10.10 on my macbook pro. This is the way I did it:
-Installed osx and created 2 partitions in disk utility, one for osx and another formated as dos fat to manually hybritized my drive and allow for windows installation (the new bootcamp is currently messed up, so can't do it that way).
-Installed win7 by bio booting the cd, and deleting the formatted partition (dos fat) and creating a new one via win installation.
-Installed ubuntu by bios booting the cd and creating its own partition in setup.
Now, when I turn on my macbook and press alt, 2 icons come up, mac and windows (so good so far!). But when I go into the windows option, grub loads and I see 5 entries:
-Ubuntu
-Ubuntu safe mode
-Memtest
-OSX 32 bit
-OSX 64 bit
Obviously osx is not going to boot under bios boot. But where is win7 that should be in the list?

I am having problems with triple booting my system. The original Linux OS I started out with was Ubuntu, which I was able to triple boot in the desired configuration (Mac OSX, Unbuntu, and Windows XP) after several tries (the instructions I got weren't quite right). I am now trying to install openSUSE instead of Ubuntu. However, if I install openSUSE before Windows XP, Windows XP erases my installation. If I install it afterwards, it seems to erase Windows XP, as it becomes unbootable thereafter. Perhaps this is because I am following the instructions for installing Ubuntu (format partition 3 as Ext3, mount it as /, and install the grub boot loader inside that partition), without modifying much else. I can't seem to find any good instructions online to tell me what else to do.
the instructions on installing Ubuntu screwed up because it said I had to install Windows XP first, before installing Ubuntu. I found out it was the other way around. Also, while Ubuntu was installed, all three partitions showed up on disk utility (although the Linux partition wasn't a recognized file system). However, every time I've installed openSUSE, where the partition should have been showed up as empty space on disk utility.

I installed Scientific Linux 5.0 distro on my notebook, Dell 1558 (2.27 core i5, 4G RAM, 500G HDD, 512M ATI, win7).Unfortunately, I didn't backup my data on partiotions D, E, Now, I can't re-install windows 7 because it couldn't detect proper partition!Is there any way to remove linux and re-install windows 7 (or have both on the same hard disk) so that I can access to my data on partitions D, E,.By the way, I used "partition Wizard Home Edition v5.0" to re-format the partitions, but there were just disabled options. The hard dist became "Dynamic Disk", so I couldn't do any operation. Is there any solution to convert dynamic hard to static one and don't lost it's data?

This seems to be a variant of a problem many people have had, but after several hours trawling through various forums, I haven't seen a reliable match for my situation.In brief:Adding a third boot partition (of Ubuntu) to my existing dual boot of OSX 10.6 and Windows 7 seems to have crippled the Windows boot from working, because Grub apparently takes over the process. Yet Grub does *not* appear to be on the Windows partition.
More verbose:I have an older MacBook Pro (3.1, running Snow Leopard) that I recently refitted with a new 240GB SSD HD. With the extra space (it was previously only 120GB) I decided to add a dual boot with Windows 7 using bootcamp. This all went swimmingly well.Encouraged, I decided to follow this Lifehacker article's suggestion and triple-boot the machine with Ubuntu (I'd never used Linux before):So I now have the nice rEFIt boot partition selection screen, and, indeed, I'm up and running in Ubuntu, and enjoying it.
Only one problem: I can't get into Windows any more. If I try to go in through rEFIt *or* by holding down OPT at startup and selecting the windows partition directly, the result is the same: I get thrown into Grub's selector, and selecting the Windows partition from there leads to an error message and a dead end.Having read through numerous postings, I get the impression that Grub is doing something or living somewhere that it ought not to be, but in most cases I've seen, people had accidentally installed Grub onto the Windows partition (or indeed onto EVERY partition). So far as I can tell, this isn't the case with me. Here's my boot summary:

Is it possible to install a different windows manager? Currently I am using an HP Netbook 210. The windows manager I am using is "gnome-shell" that comes as default with Fedora 15. However, I am wondering if I could completely remove this and install a different windows manager, such as Xfce 4.8. I am not talking about completely removing Fedora 15 and then installing Fedora 15 xfce spin. Just the window manager. How easy would it be to remove the gnome-shell windows manager and then install xfce 4.8 windows manager? Any steps to do this?

Installed ClearOS Enterprise 5.2 Worked a little bit... The i wanted to delete ClearOS.. So i connected 500GB HDD and booted again in Acronis Disk director Formated the entire 160GB HDD.. Copied back the entire 160 from 500GB HDD.. Now my sytem refuses to boot... Just 4 letters "GRUB" appears on the screen... I tried booting using XP CD.. It gives a blue screen.. I tried Windows 7 CD.. It says unable to fix due to MBR problem..

As the Title states, "update-grub" does not detect the windows xp partition on /media/sda1. And, when I attempt to mount it from teminal nothing happens, and from nautilus I receive the following error: "Error mounting: mount exited with exit code 2:
mount: only root can mount /dev/sda1 on /media/sda1" I am root.
