Ubuntu :: Restoring Windows 7 Bootloader With WUBI?
Oct 14, 2010
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 hope this is the right sub-forum for a question like this. It seemed like the best match from what I could find, but my issue stems from installing Windows 7 after I already had Ubuntu installed. I don't know what details are important, so I'll be as thorough as I can. I was running Ubuntu 9.10 on a machine with two SATA hard drives. I was only using one since Ubuntu kept complaining that the second drive was having some issues. The drive with Ubuntu had only two partitions, one tiny one for the swap and the rest of the hard drive was the second partition.
I needed to install Windows for my work, and since I was not very familiar with the whole partition thing (which is the reason why the hard drive was basically one huge partition) I decided to follow this guide: [URL]... I backed up my important data, I used a live CD to create a new partition for windows, I backed up my MBR using the command given, and installed Windows 7. Everything went pretty smoothly. Now, whenever I boot up I don't get a choice of what OS to boot, it just goes straight to Windows, as expected.
I used the same live CD to restore the MBR using the command given on the guide, but I get this error: dd: opening `/media/sda/mbr.bin': No such file or directory
I had to install windows for my sister, and I had a 20gb partition there for backup ( /data/ ), and well, that's where I was going for. After reformatting and installing Windows, I try restoring grub and this is what I get:
Probing devices to guess BIOS drives. This may take a long time. /dev/hda: Not found or not a block device. Searching for an alternative way to install it, I found that if I 'installed' Ubuntu over my Ubuntu partition, it would automatically restore grub. But when I get to the partition tables, I get a message saying that "The computer has no operating systems on it" and it considers my hard drive as empty.
Keep getting the same error message trying to install via Wubi under Windows XP. When I download and run wubi.exe, I get an error message that I can't dismiss that reads: Windows - No Disk There is no disk in the drive. Please insert a disk into drive .(sic) I've tried downloading the appropriate .iso and putting it in the same directory as wubi
Every time I attempt to restore, maximize or resize a window, there's a noticeable delay (a couple of seconds) before it happens. This doesn't happen with desktop effects turned off, so I figured it's somehow related to compiz. However, I have no idea what it is..
Running new 10.04, using proprietary ATI drivers for Mobile Radeon 3650
I am pretty new to ubuntu, and not sure if this question has been solved by anyone, I tried search this forum, but didn't find enough information. The closest thread I found here was this one:[URL].. Here is my situation, I have installed Ubuntu 9.04 a few days ago with an old Live CD, after running it pretty well, I upgraded it to 9.10 with the online update tool. (I guess this makes sure I was using Grub 1, the legacy Grub). After updated to 9.10, I installed a Windows XP on my hard drive, obviously, it wiped off my Grub from the MBR. So I tried to restore the Grub back to the MBR, but failed, please see below:I first run the fdisk
My Windows installation had a problem and I had to reinstall Windows. The problem now is that I need to get grub back so that I can boot into Fedora. I'm using a Fedora 11 LiveCD I had sitting around. Here are the results of the command most of the way down the first page:

I'm tempted to try the grub-install command quoted near the end of the thread, but I don't want to do anything that will hose the system.
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?
recently I've installed Opensuse 11.4 dual booting beside windows 7 . now I want to restore windows 7 boot to remove OpenSuse 11.4 ...I've tried many ways to remove grub and restore window's boot . I tried bootrec /fixmbr and bootrec /fixboot but in when it comes to the last step it says (cannot find system path )I also tried nt60sys method to restore windows boot and it failed 2 sound like the grub installed is rock solid one
I backed up my laptop months ago. Today i repartition the drive and used sysresccd with partimage to restore the HDD. I got a success msg after restoring however when booting i get a bootmgr missing error. How do i fix this?
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?
My computer initially had one hard drive, with Debian Lenny 5.0.4 installed. I haven't done any special configuration, so upon boot, I was presented with the GRUB kernel select menu, then gdm, etc. I think I used the Debian installer's 'use entire drive with LVM' configuration.
I then added a second hard drive, with the intention of installing Windows XP on it. After I installed XP on this second drive, I found out that it had overwritten the MBR on the first drive. (It was my intention do use the BIOS' F8-key boot menu to choose between the two drives, each with their own distinct boot loader. The two drives and OS's would be completely independent.)
Using my Debian installer CD, I think I have GRUB installed on the first drive again. I've found a number of tutorials which say I can use 'set' and 'linux' to boot the system, but the linux command always returns a file not found error.
I think my LVM filesystem is still intact, as the Debian installer's fdisk reports it, it can also chroot to it and my installation appears to be intact. 'ls' within GRUB shows (derek-swap_1) (derek-root) (hd0) (hd0,1) (hd0,2) (hd1) (hd1,1) (fd0) . 'derek' was the hostname I used.
I would like to simply restore the system to the way it was before: with the standard GRUB that comes with Debian 5.0.4, which then boots into the debian with my LVM filesystem. Is there a way to do this from the Debian installer CD? (I was hoping there would be a 'dummy install' command which would install GRUB and configure it properly, but leave all my existing partitions and filesystems intact.)
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 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?
I purchased a Windows 7 upgrade for my PC and plan to do a clean install of 7. I currently dual boot Windows Vista and Ubuntu. I understand when I run the upgrade, it will replace the GRUB Bootloader (Ubuntu Bootloader) with the Windoes Bootloader, when this happens, I won't be able to get back into Ubuntu. How can I correct this issue and reinstall the GRUB Bootloader?
I downloaded Ubuntu 10.4. Then I downloaded Windows 7 Pro. the bootloader got overwritten with windows 7. I cant get to the ubuntu side to do the whole sudo command to reinstall the bootloader because I do not have my ubuntu cd. Can someone please explain to me in detail how to install the bootloader from my windows side.
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 would like to get the winodws bootloader as the default bootloader instead of the Fedora one. I don't mind the Fedora bootloader, but I use windows more so it gets annoying.
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)
