Ubuntu Installation :: Windows Does Not Show Up On Grub2 Bootloader
Jul 19, 2010
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

GRUB2 does not show Windows-XP Pro in the menu anymore.
Probably already posted before; however each case usually is somehow different. I use Ubuntu only occasionally to learn how it works.
After the latest update using Update Manager, quite a few packages were installed without any problem. However GRUB2 does not show the Windows-XP(Prof) partition in the menu anymore. Now I can't boot Windows because I can't select what is not shown.
1. This what I get with command "sudo fdisk -l" (in the present situation)

It is already the second time that GRUB2 changes the menu items as it pleases, messing up the bootmenu. How can I repair the bootmenu in order to be able to boot Windows-XP, as before the updates ?
The current Ubuntu version is now 10.4 LTS The current GRUB version is "GNU GRUB version 1.98 Ubuntu10"
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.
So, as the title says Windows 7 doesn't show up in GRUB2's selection menu, but it does show my Windows XP professional option that I had before Linux and then reinstalled. After searching very long for the problem in Linux and GRUB2 I decided to boot into XP, witch gave me the option for Windows 7 or older versions of Windows -> so I eventually can boot to it! So here is the real question: How can I make an entry for Windows 7 and for Windows XP? This is because I'd like to use a theme for GRUB and it would be to stupid to make GRUB look nice if I then come to a stupid screen of the Windows loader!
I have a Dell Studio 14 laptop with Windows 7 64bit preinstalled. The processor is core i5 and the machine has 4GB RAM. I freed 25GB of memory from my Hard disk and tried to install Ubuntu 10.04 (AMD). Everything went fine. I restarted and Logged into Ubuntu. It worked like a charm. Then I restarted to Windows7. This also worked well as expected.
But, when I rebooted again, I got a black screen saying that �No modules found. Press any key to restart� When I press a key, it says �No operating system found�, probably after checking through a network (it printed lines starting with PXE).
I tried exactly in the same way with Ubuntu 8.04 in my machine, and this worked without any problem. The Bootloader was not corrupted after restarting from Windows. I noticed the problem with Ubuntu 9.10 and 10.04. I feel like a problem regarding the bootloader version. AFAIK, 9.10 and 10.04 is using GRUB2 when 8.04 use the old version of GRUB. Will I have to switch to the legacy GRUB? (I would love to keep using GRUB2). If yes, I would like to know How.
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.
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 wanted to switch to Linux from Windows so I decide to install Debian. The installation completed successfully but after that the bootloader doesn't show after the system reboot. So it is just black screen. I have an option for booting Debian (which will go to a black screen) and go to command line which looks like command prompt in Windows. I tried going to the command and it shows
grub>
I don't know which command to input since I'm a newbie and not familiar with Linux. I installed Debian from USB using unetbootin. What I should do to successfully install Debian?
i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again. i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.

I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?
Basically I had windows 8.1 running on my fujitsu lifebook A532 laptop and wanted to dual boot kali linux alongside it, however upon installing the linux it deleted EVERYTHING! on my laptop, the grub bootloader only showed kali linux to choose from...
I then decided kali linux is too complicated for me and decided to delete everything and reinstall windows 8 again however I was surprised that my bios screen looks diffrent also I can not edit the boot sequence.
If I press f2 or f12 it takes me to a screen with a tab named Boot menu and its written on it debian and every time I press enter on it it takes me back to this same screen...
I recently installed Ubuntu 9.10 onto my second hard drive, and now I can't boot into Vista (installed on hard drive #1). Grub2 just doesn't seem to be recognizing that there is a Windows Vista installation on the first hard drive.
I followed this guide (with Fabien's changes) because it seemed like they were having the exact same problem. But after rebooting, Vista is still not showing in the GRUB menu. In fact, the GRUB menu doesn't even show up unless I press Shift because it thinks that Ubuntu is the only OS installed on my computer.
My results with boot_info_script:
Code: ============================= Boot Info Summary: ============================== => Grub 2 is installed in the MBR of /dev/sda and looks for (UUID=e94a058d-1d19-4a98-924b-1a5fce405bdd)/boot/grub. => Windows is installed in the MBR of /dev/sdb sda1:

When I was installing Ubuntu to HD2 (the 500gb one), I got a peculiar message saying that Windows was installed on it. There wasn't anything on HD2 though, because Windows Vista was most definitely installed on HD1.
However, if I chose to overwrite HD1 with Ubuntu, the message wouldn't come up. It seemed like the installer was confused as to which hard drive actually held my Windows Vista install.
Awhile back, I made my desktop a hackintosh. The only way to boot it was Chameleon, which I was totally fine with because it looked nice. Currently, I removed OS X, and now only have Windows 7 and Ubuntu (10.04) installed. My gripe is that GRUB2 looks butt-ugly... it's still the basic white-text on black-background, without any graphics or anything. Is it possible to remove GRUB2 and replace it with Chameleon? Or maybe can Ubuntu start using Chameleon as the bootloader in future releases?
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?
i've been using ubuntu with wubi, and I'd like to install it on my new hard drive (so windows is on one hdd and ubuntu is on another). afaik, grub will be installed on the hdd w/ ubuntu, and i have to set it to recognize the other (windows) hdd. assuming that i want to get rid of ubuntu and just use windows, what steps do I have to take to do so? (if grub is only on the ubuntu hdd, then would I just have to format it?)
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
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)
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'm trying to change the font color of the text of the bootloader in Grub2. I'm running 9.10. I successfully edited the Grub cfg file change the colors of the Grub menu, but I'd like to change the text color as I watch the modules load and can't seem to do it. I'd also like to password protect the bootloader if possible. I installed startupmanager but the new version won't allow these changes. I like to see my modules as they load and wanted to change the color from white to blue.
I know practically nothing about Linux but am trying to learn. I actually want to get certified Linux+. So I figure this forum would be a great resource. Anyway, I have a dual boot situation going on my laptop with Windows XP and Ubuntu, and am pretty frustrated that I seem to forced to use GRUB. I really dont feel like reinstalling. Is there a way to simply change it back to using the Windows bootloader?
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)
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?
I have extracted the files from a bootable CD to /dev/sdc2/bootable/winpwrec with the hope of booting from the hard drive. I have read the grub.cfg file and a couple of guides here and I'm still not sure what I'm doing. Is there any chance someone can tell me what I need to add to the grub.cfg file to add this to the boot menu? I am pretty well-versed in computers but I'm new to Linux and I'm still trying to get acquainted with the OS, terminology, and the boot loader. I'm using Ubuntu 9.10, if that matters.
