Ubuntu :: Possible To Have Two Boot Loaders In MBR / Delete Bootloader For Windows 7?
Jan 14, 2011
I just received a service pack update for Windows 7, and now when I boot Windows 7, it continuously restarts telling me its for the update. Is it possible that I have two boot loaders in the MBR? And if i do how can i delete the bootloader for windows 7?
I have Ubuntu 10.04 LTS and Windows XP installed on my laptop. Usually when booting, I get the GRUB 2 menu and I can boot into either Ubuntu or XP.I was playing around with EasyBCD, then after trying to remove it I was unable to boot into Windows, I used a Windows 2000 CD recovery console to fix the MBR (using: fixboot and fixmbr).Now Windows starts up when I power on, but I don't get the grub menu anymore with an Ubuntu option. If I boot from the Ubuntu Live CD and try to mount my Ubuntu partition (/dev/sda5) I get this error:
mount: wrong fs type, bad option, bad superblock on /dev/sda5, missing codepage or helper program, or other error In some cases useful info is found in syslog - try
I am getting a new computer with Windows 7 installed. It will contain a second hard disk on which I will install Fedora Linux. I plan to put grub in the /boot partition of that disk,so I won't be able to boot Linux directly to start. I plan to use the Windows 7 bootloader to dual boot, and I understand in principle how this is done. I set up a previous computer which was running Vista this way, using the program Easy BCD which simplified setting up the Vista bootloader. But the Easy BCD website doesn't address the question of what to do with Windows 7.
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 have windows xp on my first hard drive and Linux on the second hard drive.The windows hard drive is labeled hda1 and the linux hard drive is labeled hdb1.I am using GRUB to boot the linux hard drive and it is installed on hdb.Is there any way to boot the secondary linux hard drive using the windows bootloader?I have tried several online tutorials for it but none of them work.
Whenever I load Ubuntu on a machine with other OS(s) loaded it always recognizes and adds an entry in the bootloader menu. Not this time. Well kind of. After the install my windows boot option was in the menu, but after an update it is no more. I see the different Linux images... but no Windows boot option. Can someone tell me how to add my windows XP boot option back to the bootloader? I have XP on the the on the 5th partition and Ubuntu on the 6th...
I have removed Ubuntu and I just have Windows 7 installed.
When I turn on the laptop, Grub tries to load but it fails. I have used Windows 7 install DVD and clicked into repair windows start so I should get Windows default bootloader back, but when I restart, Grub is still there...
How do I remove grub and get the laptop to boot into Windows automatically?
This is my HDD, btw: [URL]
Note: I'm booting right now using iBoot, how do I repair this problem? I may run chkdsk, Windows asks me to run it every time I boot into it since 1 or 2 weeks... maybe it won't repair the boot loader until I ran chkdsk, I dunno
I think I have the opposite problem of many I need to blow Windows 7 away completely.No dual boot...just 10.10 only.
I started with the live CD...so I don't know if this is a "wubi" thing or not. I'm trying to install onto an Intel X25 80GB SSD which formerly contained Windows 7. "Use entire disk" option chosen. The install went like a dream, a sheer joy to watch. Until I went to restart and there was Windows Boot Manager telling me there was a problem with my Windows installation. Correct, it's gone!
I started the live CD again, fired up gparted and deleted everything on on /dev/sda - the lot. Reinstalled 10.10 - rebooted - Windows Boot Manager still there. OK, yet another try. Back into live CD and this time fdisk, followed by shred, followed by verify that there's no partition table in gparted. Empty volume, no partition table.
Reinstalled 10.10 again & restarted. Yes, you guessed it. Windows Boot Manager is STILL there!
What on earth must I do to rid myself of this hated Windows Boot Manager? I feel like a complet twit, because I've installed Ubuntu over XP (etc) many times (on rotating rust, not an SSD admittedly but...a "disk" is a disk...is a disk)
I'm using Truecrypt to encrypt my Windows 7 OS. I also have unencrypted Ubuntu 10.04 installed on /dev/sda6 on the same hard drive. Since Truecrypt bootloader must be installed in MBR, I have GRUB2 installed on /dev/sda6, so I can use TC bootloader to load GRUB2. When I first install GRUB2 on /dev/sda6, I can use TC bootloader to load Ubuntu. But, if I boot into Windows via TC bootloader, and then later try to boot into Ubuntu, I get the message "no bootable partition found". I have to reinstall GRUB2 onto /dev/sda6, every time after I use windows in order to be able to boot into Ubuntu. It seems that starting Windows somehow overwrites GRUB2. Is there a fix for this?
I installed Ubuntu, with a dual boot functionality and worked great. I was recommended Backtrack 4 and I installed it in the system. Now, I try to use the dual boot with Backtrack, Ubuntu and Windows 7 and only Backtrack works. I tried the restore disks that I created when I got the laptop, but the problem persists. s there a way to delete this Backtrack from the system and go back to Windows 7?
i want to boot windows from grub loader and delete linux .Is this possible?or can i keep only /boot partition so that windows boot from grub prompt i want to boot windows from grub loader and dont want any linux partitions on my machine.Is this possible?or can i keep only /boot partition so that windows boot from grub prompt and delete rest of the linux so that i can get all free space.it is not possible for my system to get windows boot loader hence i want only grub boot loader to load only windows.
I work for a SUN resller in South Africa, I have recieved a request from a customer for a autoloader with LTO3 or 4 drives. Where can I find out what auto loaders and interfaces (SCSI or SAS) are supported.
i turn on my computer today and the windows partition that is normally there is gone, i don't know why or where it went. the part of the harddrive still exsists because i still have the 282GB partition that i can look at through ubuntu.i have is that for some reason since i upgraded to karmic koala, i have a bunch of old kernals also chilling on grub doing nothing, how do i rid myself of those?
3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?
My setup is like this: * Installed Windows 7 on primary (SATA) hard drive * Installed Ubuntu 11.04 on secondary (IDE) hard drive
I've worked with Wubi before, and I liked it so much, I decided to go full scale with Ubuntu. However, I think I've missed an option in the setup, because Grub has now taken over my bootloader. I tried reverting to the Windows loader with EasyBCD, but booting Ubuntu from there is impossible, since it doesn't show itself. By the way, I don't really understand EasyBCD, so that makes it even harder. Anyway, what I'm trying to accomplish here, is to get a bootloader which uses Windows as default and Ubuntu as secondary OS. How do I do this?
I am trying to install Ubuntu10.04 on my machine which already has on it, Win XP. Lemme lay down the setup of my machine first of all.
I got a new 320GB HDD of which I have taken 20GB as the primary partition and installed Win XP on it. Took another 220GB as an extended partition for my data storage. Around 63GB was remaining which I left it as unallocated. Decided to try Ubuntu, but preferred to boot it from the windows bootloader. Downloaded and burned the Ubuntu-10.04-desktop-amd64.iso(have a AMD x3 425 machine) and tried an install on 30GB of the 63 left.
I did not try any partition scheme. I chose the manual partition option, made a 28GB ext4 partition, made it primary, mounted the /, took another 2GB for the swap and proceeded. Chose advanced option and installed grub on the 28GB(/dev/sda6) and completed the installation.
Since no grub was installed, Ubuntu was not available. So then, used the bootpart utility to point grub to the windows bootloader, but it did not work, was giving me error when I chose Ubuntu from the bootmenu modified by the bootpart.
So tried booting with the same install cd, chose Live Ubuntu this time and mounted the 28GB, copied the first 512bytes using dd if=/dev/sda6 of=ubuntu bs=512 count=1 to a usb drive. Rebooted into windows and copied the file to C: and added it to the boot.ini. Rebooted and tried choosing Ubuntu from the boot menu but it does not work. I get a blank screen with the cursor blinking.
The machine is new and BIOS is LBA enabled by auto.
i had a dual boot xp/ubuntu first. later i had to format and reinstall xp. this deleted the grub bootloaderplease let me know, how to fix this! please make it simple . i have the live cd, but i don't have internet connectivity in ubuntu.
So here's the skinny, I have Windows 7 home Premium installed on my Touchsmart PC. I have a 60 GB partition I want to use for Ubuntu. Can I install Ubuntu to that partition so that it doesn't change how my computer boots up already?
Example:
I press the power button. The POST test processes and then boots into windows no questions asked, as if it's the only OS on the system.
I want to keep it that way even after Ubuntu is installed.
I want Ubuntu ONLY accessible by using the BIOS boot menu as soon as the PC starts up.
I have a netbook dual-booting Windows 7 and Ubuntu Netbook Edition via Wubi. Ubuntu crashed on me while I was recording a screencast and I rebooted to find the Windows bootloader no longer works. It simply gives me an error ("cannot load bootfont") for a split second and restarts immediately. I'm able to access the grub menu with a bootable USB drive and access the Wubi partition, but I can't boot Windows, including the Windows recovery partition. I can still boot Ubunutu.
My question is: is there a way to restore the Windows bootloader in Ubuntu? If not, how can I replace it with a grub bootloader and keep my Wubi boot options intact?
I was wondering if i could reinstall the windows bootloader with the ubuntu installation cd..because with the current ubuntu installation the windows 7 installation dvd doesnt load up. when i use a windows xp cd, the computer tells me that there is no active hard drive. other linux distros work just fine
I installed Ubuntu and Windows 7 on my computer. I first get the Windows bootloader telling me choose between Windows or Ubuntu. If I pick Ubuntu, I then get a GRUB loader telling me to choose between different versions of Ubuntu and Windows 7. How do I remove GRUB and just use Windows bootloader?
When I try to boot into windows through grub it just returns to the grub menu.also system recovery options from bios just end up in grub screen too.here is boot script.From reading forums I think I need to get grub out of windows partition but I don't know how
I'm relatively new to Ubuntu, I've installed it in Virtual Box and through Wubi on other computers but this was the first time that I've done a live install on my production computer. I had problems from the get go, I was using a Live CD of 10.04 (64 bit AMD) to install it and when it got to the part about choosing a partition no drives would show up at all. Eventually after some searching around, I discovered that Using an Alternate install CD would work. I did that, installing Ubuntu into one of the free partitions I had set up prior to this. Eventually my system turned on but the monitor went to sleep so I had to hit E on the grubmenu and change something to nomodeset (or something like that) so that I could see the screen. I installed Compiz and it was all good from there.
Except for One issue, I cannot boot Into windows at all, it doesn't show up on the bootloader even though the partition shows up in Gparted. I've tried updating Grub2 with no results, here are the results of Sudo fdisk -l Disk /dev/sda: 400.1 GB, 400088457216 bytes 255 heads, 63 sectors/track, 48641 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: 0x1549f232 .....
i just installed Ubuntu from an ISO about a year old and of course i updated it to the latest version and when i get that screen at startup where i have a choice of which version to load i get something like this: My current version, memtest, an old installation of Ubuntu and some really old versions. The problem is i also have Windows7 and Vista installed(vista really needs to go) but i don't have either of them as a choice in the bootloader. How do i get it back? Also before the update i had it on the list.
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 -Memtest Debug Mode (or something to that effect)
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).
I have grub installed which boots both my ubuntu and windows which are in seperate partition. I'm about to format my windows, will it affect anything? Like though my ubuntu will not be formated nor the bootloder but shouldn't the windows bootloader overwrite somethign and make it default? Thus making ubuntu impossible to boot?
