Ubuntu Installation :: Removing Windows Entry From Grub Bootloader?

Jan 26, 2010

I currently dual boot and wish to know how to remove the Windows partition/drive while still allowing Ubuntu 9.04 to load safely as my main OS. I know how to restore windows partition by;

If MBR gets damaged boot from MS Windows Xp disc, Select "R" for "recovery console", select main windows installation drive (admin password usually nothing, just press enter) and type "FIXMBR" this will allow you to boot windows again, but Ubuntu partition will be unbootable and require installing ubuntu again to dual boot.

But this leaves Ubuntu partition Un-bootable as it removes the grub menu, how would I do the same for Ubuntu and make window partition un-bootable so I can remove it?

Ubuntu :: Removing Entries From Grub 2 Bootloader?

Jul 8, 2010

Since I've been using Ubuntu, I've noticed that new entries for Ubuntu (the same but with the final number changed) occasionally appear in the Grub 2 boot loader. I'm talking about the first two entries in this picture, compared with the third and fourth entries here:Two questions:1. What are these entries? They appear to simply be the same OS but different versions. Are they generated when Ubuntu updates?

Ubuntu Installation :: Windows 7 Overriden By Old Windows XP Entry - After Reinstall Grub

Oct 7, 2010

I am actually facing a vague problem here. I was previously running Windows XP and Ubuntu . Ubuntu was installed Windows XP The problem is

1. First I tried to do some disk partitioning. That ended up with some error.

2. Ignoring that, I went to install Windows 7 over Windows XP but I was not able to proceed with Windows 7 , because the partitions were corrupted.

3. So I used Ubuntu LIVE CD (Grub was lost at this point )and used 'testdisk' and recovered the partitions.

4. Now installed the Windows 7 successfully.

5. Now again I moved to Ubuntu Live CD to write the GRUB. After which I tried restarting

6. Now Ubuntu is booting perfectly as before. But the problem is with Windows

7. The GRUB loader instead of showing Windows 7, it shows Windows XP !!! . and there is no other entry for windows. When I tried opening it, it says "error, cant read file" and further inout moves back to the grub loader list again.

"How do I change the entry to Windows 7 from Windows XP and boot Windows7 successfully " I tried it a couple of times, same thing happens . So how to change the entry?

Ubuntu Installation :: Add Windows 7 Directly To GRUB 2 Bootloader?

Oct 30, 2010

Anyhow, I'm a n00b to the Linux world, so I installed it on my Windows 7 desktop to dual boot. Current configuration is as such:160GB HDD with 3 partitions: Ubuntu Studio 10.10 on one, Win 7 on another, and the third is for storage.1TB HDD for extra storage.So far, all is well, but I'm not pleased with the default GRUB options and layout. It gives me 4 options to choose:

-Ubuntu Studio
-Memtest Debug Mode (or something to that effect)

Ubuntu Installation :: Remove GRUB, Restore Windows Bootloader?

Jan 15, 2010

Basically, I used a USB stick to run ubuntu 9.10 live, then tried to install to an external 500gb HDD connected with a Sharkoon Drivelink USB adaptor. The installation went fine, but I get a GRUB error 21 when booting a lot of the time. I figure this is due to the way in which the drive is connected. I am a complete noob, and I want to just ove GRUB completely and restore my Vista bootloader. Unfortunately, I do not have an installation disk as my laptop didn't come with one, and none of the others I have other PC's are the same version (home premium 32-bit).If you know of a way to fix the GRUB issue/sso I can use the external drive I would love to hear them too, but the main aim of this thread is to help me remove GRUB and restore the windows bootloader. If any more information is needed, just ask and I will provide it.HP Touchsmart TX2-1010Windows Vista Home Premium 32-bitExternal HDD:Seagate Barracuda 7200.11 SATAII (with jumper set for 150mbps)

Ubuntu Installation :: Lost Windows Entry In Grub After Update

Jul 9, 2010

Ubuntu's update manager recently updated the Grub menu.lst file. It let me decide if I wanted to keep my old menu.lst or the new one. After deciding that I was fine with the new one, I found out that I can no longer boot into Windows 7. I had previously edited menu.lst so that Windows would be at the top of the list, however, I didn't notice that this had put it into the automagic update area, and I realize now that I should have just edited what the default number was instead of moving around the entries.

Anyways, I can no longer access my Windows 7 OS via Grub, and I was wondering what sort of fix I can have for this. I've tried running update-grub, but it hasn't fixed the problem. The Windows bootloader is on the first partition of the only hard drive, as far as I can remember.

Fedora Installation :: Switch Back From Windows Bootloader To Grub?

Feb 4, 2009

I thought it would be cool and easy to install Windows 7, ended up being a headache and worthless so far. Now I only have the windows bootloader with vista and windows 7 as options. How can I get grub going again? I have all 6 fedore core 10 cds and a live cd in case those will help, I am using the live cd to play in fedora right now, but I am not sure how to get access to grub.conf and what to change in it, because I am pretty sure I have to add Windows 7 to it.

Ubuntu Installation :: Grub Woes After Removing Windows Etc?

Mar 15, 2010

I have Karmic installed, but still using old grub from Jaunty. I decided to get rid of my Vista dual boot so I used gparted, deleted the partitions and moved and enlarged my Ubuntu ones. Grub then didn't work, presumably because I deleted the MBR. I then installed Opensuse 11.2, which I assume still uses old grub too. This gave an Opensuse option which worked, and a Karmic option which took me to the Karmic bootloader, but Karmic did not load. I then tried some instructions to repair grub using the Ubuntu installer, installing grub to my extended partition. This tells me there is no operating system found. I then tried following the instructions at [URL].

My fdisk -l looks like:
dev/sda4 * Extended partition
dev/sda5 Ubuntu /
dev/sda6 Ubuntu /home

Fedora Installation :: Grub2 Bootloader - Manually Adding Entry?

May 29, 2010

I have a working Ubuntu install with the Grub2 bootloader. I need to manually add an entry to boot Fedora 13 off of sda. Sda1 is the boot partition, sda2 is LVM. None of the examples I've tried work. I do also have F13 grub installed on sda, but chainloading to it didn't do anything other than a blinking cursor.

Ubuntu :: Remove GRUB And NOT Restore The Windows Bootloader

Oct 31, 2010

Is there any way to simply remove grub? Does GRUB reside in a specific partition? Do I have to just delete the partition that has GRUB on it?The way my bootable partitions work is something like this.

1)Installed Vista

2)Installed Ubuntu

3)Thought I removed GRUB

4)Put in new HDD(1) and installed Win7 onto it

5)Put in another new HDD(2) and put another Win7 onto that (but I disconnected every other HDD so that the bootloader would be written onto the new HDD(2). When I have all my HDD's plugged in now, I get a GRUB load error (I think it's 21).

General :: Unable To Boot With Ubuntu And Windows 7 - Grub Bootloader Getting Removed

Sep 2, 2010

I have recently purchased a new laptop, which came with Windows 7 pre-installed. I immediately installed Ubuntu alongside it with a dual boot. At first it worked fine, but when I restarted after the first time I used Windows, I ended up with an 'Operating system not found' error. I was able to reinstall the Grub bootloader using an Ubuntu Live CD, which appeared to fix the problem, but the next time I loaded Windows 7 and rebooted, the problem reappeared I think the problem is that Windows 7, for whatever reason, is somehow removing or disabling Grub.

Ubuntu Installation :: Grub Entry Gone After Upgrading 9.10

Jan 6, 2010

I have installed ubuntu 9.10 and everything was working fine. Just a minutes ago a window popped up telling me that a complete update couldn't be completed, and asked me to go on with a partial update. I did it and then a window popped up (I think it was debconf running) asking me if I wanted to delete phpmyadmin database configuration or if I wanted to keep it... seemed like the updater was removing quite a bunch of packages!

After that I was presented with a long list of packages to be removed (among them apache2, php5, linux headers, etc.) I thought it was going to remove them in order to reinstall them latter, so I let it go) but now there's no ubuntu entry in the grub menu, so I had to boot with windows! Right now I'm downloading ubuntu 9.10 livecd to give it a try...

Ubuntu Installation :: Add 9.10 Entry To Another GRUB Setup?

Jan 14, 2010

My problem is this, I decided to try Pardus since I had the disk space available and learned that it never created a entry for Ubuntu 9.10 64-Bit. I have tried many different boot options and have only gotten it to show the first black and white bootsplash but never can continue to boot. Is there a option I am forgetting to add via Pardus's GRUB editor or is it something else?
