I am currently using Windows Vista and Linux Ubuntu (I'm not 100% sure which version).However, whenever I start up my PC, I get greeted to the HP BIOS screen, and then after that, I get the Windows Bootloader.Now, this is where things get interesting:If, on the Windows Bootloader I select Microsoft Windows Vista, it loads Vista.If I select Ubuntu on the Windows Bootloader, I get treated to a second bootloader (I assume the Ubuntu Bootloader).I'm wanting to remove one of the bootloaders (keeping Vista as my primary OS, but still having access to Ubuntu in the bootloader). As a result of this, which bootloader should I remove, and how would I go about removing such bootloader?

I've installed CentOS 5.5 64-bit on an external WD 500GB HDD. I went through the installation setup, and formatted the external HDD normally. (100M /boot, 250GB /, 248GB /tmp , 2.8GB swap). I also installed grub in the external HDD's MBR. After installation, I could boot up Linux on the same platform (Arrandale). However, as soon as I took it to a different platform such as Atom Pineview D525, it had all kind of problem on Grub, such as Grub Hard Disk Error, or it just hanged on grub loading stage {1.5,2}. Sometimes, if I'm lucky, I would get to grub command prompt, but rarely I could boot up. I would stuck at mounting file system.
I've searching a lot on Google, and people suggested to reinstall Grub, so I tried various method to reinstall Grub, but the same behaviors still exist. I can't guarantee the drive will boot...

My laptop screen goes blank right after the bios is loaded. Live CDs have no effect either.I installed arch linux to my whole HDD today. Last time I installed ubuntu linux to my whole HDD, the same problem happened.The way I fixed the problem last time was by formatting the HDD with an internal HDD dock and then installing windows with linux dual boot.As I do not want to go through the hassle by installing windows again, and I would be very delighted if anyone had an alternate way. I really want my laptop to be windows free!It seems to me that my laptop is somehow constructed to crash / go blank if no windows partition / boot loader is detected. I have no idea why they would do that, maybe you have a better explanation?

with reference to my this thread: [URL]
After installing Windows 7, the GRUB got re-written by the windows bootloader. Now after booting into the live cd and mounting /boot partition (sda2), I tried to reinstall the GRUB with this command grub-install --root-directory=/mnt /dev/sda as told by this [URL]
But I got the an error which says, Are you sure /dev is mounted? then i tried the same command on the / partition (sda5) which said, cannot find boot directory, Are you sure /dev is mounted?
And installation failed, now after restarting its just a black screen with grub> prompt.

I've restored NTFS containing Windows Vista. But the bootloader or bootsector got corrupted.
How can i detect what of them got corrupted?
How can i restore bootloader if it's corrupted?
How can i repair bootsector if it's corrupted?
All of these things should be done from linux or from bootable CD.

"Life has been made easier with all Microsoft systems, all versions of Dos and Windows, because each of them has to be installed in an active primary partition and so hence will always has a boot loader in the root partition." So if I already have Windows 7 installed (in a 100gig partition of a 1t hdd) how do I modify the windows booting process so that I can go on to create many additional partitions that will be used for linux distros?

I just tried to install OpenSUSE 11.3 on sda4 which is approximately the 2nd half of a 1TB drive, with a pre-existing Win7 installation on the 1st half. The installation summary (before it made any changes) told me "The bootloader is installed on a partition that does not lie entirely below 128GB. The system might not boot." Naturally, not keen on having a computer that won't boot, I aborted the installation.
Of course it's not below 128GB -- Windows is there.
Is there a workaround that is straightforward enough for someone who has very limited experience with GNU/Linux and isn't a comp-sci student?

I have a major problem installing opensuse 11.3 on my computer( hp pavilion dv6).I downloaded openSUSE-11.3-GNOME-LiveCD-x86_64 from software.opensuse.org: Download openSUSE 11.3 and made a live usb.I'm a newbie at using linux infact i never used another operating system beside windows.Now i have installed windows 7 (on c disk 100gb).My first problem when i am trying to install opensuse is that he dosn't automatic choose to make my partitions so i have to do it manualy.I was searching how to make it the best way so i desited to make 4 partitons one for ' /boot' one for ' / 'one for '/home' and a swap partition/In windows7 i made 4 new partitons
3:10 gb for /boot
4:10 gb for/
5:70 gb for /user
6:10 gb for /swap
My first question is :Is this right to make 4 paritions in windows (opensuse can't format or resize my partitions it just can edit it ) so it's my only way to make partitions( If this is wrong how can i make partitions then)
My second question is how to change the bootloader configurtation because everytime when ii try to install opensuse it stops at about 96% and it says to reconfigure the bootloader options.
If i skip this i get the folowing message
=== System Checking ===
Checking for /usr/bin/chroot binary... Passed
Checking for chroot directory /mnt... Passed
Checking for chroot directory content (bin
boot
Checking for binary /mnt/bin/ls... Passed
Trying to chroot... Failed
This is worth reporting a bug at url.

2010.07.21 while trying to install Ubuntu 10.4 I've been trying to install Ubuntu 10.04 on my Dell workstation and am unable to get the Grub-2 bootloader to load properly. It seems to be failing for lack of a floppy drive on the system resulting in an error message that reads : error: fd0 cannot get C/H/S values.
I've gone through the Grub-2 page at [URL].. to no avail and other sources having similar problems have likewise turned up no solutions. here's the background: A while back I was trying to install a different version of Linux and had the same problems, then had to set the project aside for a bit. I don't think this has anything to do with Linux or Ubuntu per se, but rather Grub.
The system is an old (4-5 years) Dell workstation that has one drive (128 GB) set up for Windows XP and a second new drive (500GB) which I installed for Linux. There is a DVD/CD drive and the system contains no floppy drive at all. In one attempt to get this working I tried modifying the BIOS to indicate there was a floppy drive - this created a failure earlier in the chain with the BIOS failing to load properly, not unexpected, just a shot in the dark at that point.
At the moment I am considering just running out to buy and install a cheap floppy drive to see if that helps. I'll never use the thing though so I'd rather find a solution that doesn't require me to spend money on useless hardware. In any case, here's the /boot/grub/grub.cfg contents:
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
#
### BEGIN /etc/grub.d/00_header ###

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.

I just installed Ubuntu 9.04 on this computer and I told it not to install a bootloader since I already have Fedora and it is my main OS. I then realized I didn't know how to add it to menu.lst here so I can't boot Ubuntu. How do I do this?

I'm an Ubuntu Lucid user who is trying Fedora 13. Successfully installed, but did something wrong at the bootloader stage. For identifier I typed "Ubuntu." the dropdown menu below was already reading sda1 as the partition that Ubuntu is on, so I kept it. Now Ubuntu is on the boot menu, but will not load... error message about an unrecognized system. How can I manually add it now? Sorry, should have done a search. I found an answer in editing the menu.conf file.

Playing on a test rig here and I want to install openSUSE in an already multi-boot Ubuntu family environment. All the 'Buntus play together nicely with grub 1.89, learning the ins-and-outs of which appears to be a lifetime endeavor.SUSE appears to be still on legacy grub, and I don't want that to take over from (almost) grub 2.0. It's fairly trivial to add things to the newer grub. Question is can I install SUSE and tell it NOT to install a bootloader at all?

I installed Ubuntu no problem, except for when it came to picking the location for GRUB2 to go, the bootloader.It error'd out on me, and would not let me select a single location, so I clicked continue without, and I'd install it manually. Well, once it got to the manual part, it said everything was kosher, but when I reboot, I am greeted with a black terminal screen.It tells me to hit tab for commands. What exactly did I do wrong, and how may I fix this? Do I need to reinstall ubuntu? I'm running off the LiveCD right now, and it's ok, but I really hate having to use a CD to even boot up.

I'm dual-booting Ubuntu and Windows, but the OS selection screen is starting to get on my nerves. It's been a while since I edited a bootloader though, so could somebody link me a resource or two?

I'm a fairly new Linux user, with my first Linux distro being Ubuntu 10.10,which I first installed around November on my laptop.Initially I tried installing it on my desktop,but the liveCD would give me a blank screen every time, no matter how many USB installers I tried. I had given up on my desktop when it installed without a hiccup on my first try with my laptop, until now. I've tried Kubuntu and Xubuntu, both giving me the same problem. Non-'buntu distros gave me no problems however. I tried Ubuntu 10.04 without success. But to my surprise Ubuntu 9.10 gave me no troubles (at first) and I am typing from it currently. When it was done installing, it asked if I wanted it to add a bootloader, and I said no because I wasn't sure if it was going to install GRUB, and I already had the Windows bootloader installed. When I restarted I found out that the last part of my sentence was no longer true, and I had to reinstall from the liveCD to get a bootloader.
So now I have GRUB installed, but Windows 7 is not appearing in the options. I edited /boot/grub/menu.lst to this
Code:
default 0
timeout 15
title Windows 7
rootnoverify (hd0,0)
chainloader (hd0,0)+1
[Code]...
I can still access my C: drive from Ubuntu, and everything appears to be in working order, so it's not as if Windows is corrupted.I've spent just about all day today and yesterday trying to fix this on my own, when I should have been studying for midterms, so hopefully this isn't too hard to fix and I can actually sleep tonight Once I get my bootloader issue resolved I'll be updating to 10.04 and then 10.10, which I shouldn't have any trouble with.

Kubuntu and win 7 have their own separate hard drives. The problem showed up when I installed the new Kubuntu 11.04 (disconnected win7 hard drive in hope that it wouldn't affect the win boot loader) . As of now, it's just an annoyance since I can just hit f12 quickly during startup and decide which one I want to boot. I tried doing what other tutorial suggest, but I am a little nervous about their instruction in reference to what number I should jot down since situation may be a little different.
Basically, I want Grub or whatever good working boot-loader to be installed (I heard a rumor that a click-able one was in the making) on my Kubuntu hard drive, and avoid affecting my win 7 hard drive (they research now with the updates to make sure you got their boot-loader running *sigh).
Here is some data I collected from partition editor, hopefully this will assist somebody in understanding my problem better:
ATA ST (where linux is installed)
/dev/sda1; type: ext4; size: 461.76 GiB; Used: 20.77 GiB
/dev/sda2 type: extended; size: 4.00 GIB; Used: 4.00 GiB
/dev/s...; type: linuxswap; size: 4.00GiB; Used: ---;
ATA WDC (Win 7 is installed)
/dev/sdb1; type: ntfs; size: 596.17 GiB; Used: 116.61 GiB

I've been using Ubuntu on my servers, deskto PC and laptop. But this time I decided to give a try for Fedora 13. Earlier my tests failed because of nVidia driver installation for every kernel update was so pain for me. Fedora's Live CD is quite stripped. It has good tools installed but it's missing OpenOffice.org. That should be mostly for demostration to Windows users.Installation with Live CD is straight forward even I haven't tried with Windows partitions (shrink or so). Ubuntu can be installed inside Windows drive (into loop file) without shrinking partitions. I don't know if Fedora can do the same.
But issues what I have got even before getting in... Disk partition tools are very great. But when I tried to install Fedora into LVM without using separate /boot partition - that failed. I am using Ubuntu's GRUB2 and it can boot from LVM root directly. And I thought Fedora-13 can do the same. I have been installing Red Hat Enterprise Linuxes many many times. And there is an option to skip bootloader installation. Why it is missing on Fedora? I just want Fedora into LVM without anything else. Ubuntu's GRUB2 can boot from Fedora's /boot -directory even it's on LVM. If I get Fedora installed.
So error what I get trying to install Fedora...Harddrive sda has just one big LVM partition, nothing else. Ubuntu GRUB2 is on MBR.I have just one 10Gb LV for Fedora, existing /home and swap. Plus Ubuntu's own root partition what I don't need with Fedora.partitioning program is completed as I like but then I get error message: Bootable partitions cannot be on a logical volume. I have tried to install using Live CD, DVD with graphics and text modes. None of them gives me option to skip installing bootloader. Another option I had on my mind is that I could try to use USB memory stick to have /boot. But I'm not sure if it works and installer will overwrite my existing GRUB2 on sda. If it works then I could move /boot -stuff into LVM and tell Ubuntu's GRUB2 to boot from Fedora's root LVM.
