Debian :: Grub Does Not List Windows When Booting
Jul 14, 2011
I have recently (today) installed Debian on a logical partition of my master hard disk, but when booting it will just list Debian or Debian recovery not listing windows at all. I know there may be some that will think that is a good thing but I do need access to windows.
I had a root about and found this thread which I thought might solve the problem as it is similar:
viewtopic.php?f=17&t=63601
But when I got to the part where I entered the command su -c "nano /boot/grub/grub.cfg" the terminal prompt changed to a > and I felt a little unsure of what I was doing as I would have prefered to have opened the grub.cfg file as a text file, as it is I recieved a syntax error.
As you can probably tell Linux to me appears to be a bit of a black art, but I am enthusiastic none the less. I will list the output of the terminal window so that you may see the steps I have taken.

I've installed Debian on another partition aside with Windows XP: and when I restart the machine it only list the Debian instalation.
When I do fdisk-l, I see this
/dev/sda1 1 12749 102406311 7 HPFS/NTFS
/dev/sda2 12750 38914 210164507 f W95 Ext'd (LBA)

I have been mucking around with Linux on and off for a while now, but this is the first time I have used a Debian distro. I have to say, it's been a pleasurable experience with it all going easily from install to now. I installed it to my external WD 1tb drive. It worked first up not a worry in the world. I have 2 internal drives also and when the installation of Debian was finished I had a GRUB with all operating systems duly noted. I was able to choose at start up between my Windoze 7 on HD0 and my PCLOS on HD1 and my Debian on HD2. (sda, sdb, sdc).
I noticed today as I was booting into Debian that the Windoze option was gone from the GRUB. I thought I'd put my trusty GRUB disc in, reboot and have the issue sorted in no time, as I have in the past. No such luck. After trying almost every option on the super grub disc I have a list of errors, 15 file not found, error 6 mismatched, error17 can not mount and error 12 invalid device. The only thing I can crank up now is windoze and whilst I have had a pretty good experience with win 7, I would like to have the option of choosing between the 3.

Recently I installed Debuan "jessie". I previously had Windows 8.1 and Xubuntu installed. After installation Debian installed it's own version of GRUB, with entries for Debian, Xubuntu and Windows. The problem is that after I selected Windows when booting, GRUB menu no longer appears. It boots straight into Windows.
It's lenovo Ideapad z510 laptop, with special button that allows me to select between 4 options before booting - one of them is "Boot menu".
I didn't use it before windows "removed" GRUB, but now there are 2 options: Windows boot loader and Ubuntu. When I select Ubuntu it loads my old boot menu (from before installing Debian).
I thought that when I use update-grub from Xubuntu I will at least eb able to boot into debian. After I did that Debian option appeared in the GRUB menu, but it didn't work - black screen.
How to get GRUB menu working again (and avoid replacing it by windows boot loader)?

i am having some issues with dual booting my SL6.1 and Windows. The situation is that i recently acquired an old hard drive from a non-working computer of mine with Windows already installed (i know the windows is functional, as i tested it on my new PC with SL6.1 currently installed & everything runs fine)
The problem is that after editing the grub.config to include windows, windows will no longer boot after an attempt to install a legit version of McAffee anti-virus software which coincidently was only after the first attempt at running both OS's in a dual-boot fashion. Except past the windows start up screen before the dreaded blue-screen.
Which is weird because SL6.1 OS will still boot & works perfectly fine like always, so it doesn't really make sense.
My current setup is:
Disk 1: Solid-State:
Boot Partition
SL6 LVM1: Root Partition
Disk 2: Hard Drive:
SL6 LVM2: User, Temp & Swap Space Partitions (Different LVM to Root)
Disk 3: Hard Drive:
Windows 7 Professional 64-bit
My guess is its windows MBR. The reason i say this is because the Hard Drive contents of the Windows software still appears intact when accessing the drive from the Linux OS. I don't won't to go through the rigmarole of re-installing both OS's. So hopefully their is a relatively simple solution.

Not sure if this is the exact right spot for this post, I've got an .ISO file of windows 7, but no DVD's to burn it to. I've read that I should be able to use GRUB to boot, but I can't exactly get it to work. I've been poking around the map function trying to sort of mount the iso somewhere within the hard drive, but I'm not sure if that's how it should be done.

I recently installed Ubuntu 9.10 and when i rebooted, GRUB fails to boot to windows. What exactly happens is that when i select Windows, it simply goes to a black screen with GRUB at the top, and a blinking cursor (that accepts no input) Summary:I am running Windows XP Professional No, i do not have the Windows disk My hard-drive has been partitioned between Ubuntu and Windows I have Ubuntu 9.10, which boots normally Windows failes to boot, and hangs on a screen that says GRUB _ I am a total linux noob I dont want to simply rewrite the mbr as i still want to be able to dual boot. I have important data on the windows partition that i want to keep.If you want any logs/info, you'll have to tell me EXACLY how to view/capture them

Every time I use GRUB to boot into Win7, I can't reboot back into GRUB or Windows. I think Windows is forcing itself into the MBR then proceeding to corrupt it. I believe I can just boot into a Live session use "sudo grub-install /dev/sda", but that seems like a lot of work just to reboot.

I need to boot into a Windows XP installer CD from GRUB. How can I do this?
(The reason is that I need to use drivemap to install to a secondary hard drive.)
Are there any viable workarounds? For instance would installing to the primary disk, copying to the other disk, and then using chainloader to point directly to ntldr work?

I have to test Ubuntu 11.04 across multiple systems in my company and enable dual booting with Windows Vista PE x86. On selecting the Windows GRUB entry, the Grub menu just loads again without loading Vista and thus enters into an infinite loop.
Fdisk -l gives me:
Code:
When I did a update-grub, the output shows that it detected and added a Windows Vista OS. Also, I went ahead and added "MyWindows" as an option as well which has (worked for all other versions)
Code:
Selecting either of the GRUB Windows entries just loads GRUB menu again. I'm very confused and this deployment is critical for my company.

I have a vista/ubuntu 9.10 duel boot laptop. Last week the screen was broken so it went back to the manufacture. Before that I rename the /etc/grub.d/10_linux file and ran grub-update so that Grub will only show windows boot menu (in case it confuses the repairman) now I have the laptop back and I am eating my own medicine.how to restore my ubuntu boot menus? I can now only boot into windows, although it seems like I can go to my ubuntu partition and change back my grub.cfg (which I did not backup!)but I can't remember the menuentry details.Is there any way, other than manually change my grub.cfg, so that I can boot into ubuntu again?

My Laptop Config is as follows.
Compaq Presario V3700
AMD Turion64
2GB Ram
Windows Partitions
/dev/sda1 == C: (WINDOWS)
/dev/sda2
[Code]...
I have been carrying out updates of both Vista & SuSE whenever i operate in them.
One (Not So) Fine Day, when i Choose from the Grub loader "Microsoft Windows Vista SP2" option it just din't boot into Vista. I have Tried many a time.
My First doubt was towards Vista only, so i choose the "Windows Recovery Mode" option from Grub. It went into the Recovery mode. I ran Memory Tests on Windows Partition, took its own sweet time, whatever missing indexes and all it carried out and finally gave the Thumbs Up result. After that, i carried out Startup Repairs, all came out well. So, Yet again i restarted and tried to get in Vista. Nope, dint work.

Right, so I've looked high and low for the answer to this problem and haven't found it, although I've found a million and a half threads about grub especially when it comes to dual booting windows. Which I'm not. What I am though, I suspect, is an idiot who shouldn't mess around with my computer at 4 am.
So the problem is every time I turn on my pc, grub tells me it can't find a file system and goes into recovery mode. Can't boot into ubuntu at all. Am using the live disk to type this.
I also think I know why grub is doing this, I was dual booting windows before, I had windows installed originally, added ubuntu to a new partition. Was having problems with grub. Figured that reinstalling it wouldn't be a bad idea, it might fix it. In that process I did something rather stupid, I accidentally installed grub to my other internal hard drive. There is no operating system on it. Just movies, music, etc. The problem, I think, is that my second hard drive is sda, and the one with my os is sdb, which I suspect means that grub is loading from sda and finding no operating system, rather than from sdb. (It's like that because my larger drive wouldn't fit into the sda slot on my computer, long story.) How do I remove grub from sda?

I will like to triple boot Ubuntu, XP and Windows 7, but I already had Ubuntu and XP running on separate HDDs, Ubuntu was installed first, then I installed XP on a separate HDD (with the Ubuntu HDD disconnected), now I did the same for Windows 7, I disconnected all other HDDs (Ubuntu, XP and Data)and installed windows 7 on a separate HDD.When I connected everything back(Ubuntu HDD, XP, Data HDDs and Windows 7 HDD, Windows 7 does not appear on grub boot menu and now Windows 7 does not boot up by it self.
Is there a way to simply add Windows 7 to Grub so I can have all 3 OS's on grub menu?Can grub search HDDs to look for OSs to add to the menu?Funny thing is the XP entry on grub appeared by it self, I've never edited grub to add XP on the booting menu, I was booting directly to XP by going into the BIOS and selecting the XP HDD as my booting drive instead of Ubuntu HDD, somehow XP was added to the grub booting menu.

I recently had to reinstall windows on another partition on my hard drive due to there not being any good way to run unrealed under ubuntu (believe me, I've tried everything) Is there a way to install grub from windows without using a liveCD or booting to a USB? I have downloaded WINGRUB and to be fair I have no clue how to use it.I no longer can access my Ubuntu partition.

I wanted windows to appear first in my grub2 menu so I renamed the 30_os_probe file(or whatever it felename is) to 09_os_probe so that it comes before the 10 linux file, problem is whenever these files get updated the updater is unable to find the 30_os_probe file since I renamed it and recreates it... leaving me with two versions (09 and 30) with 09 being of course outdated.
The updater also fails to run update-grub and instead attempts to update grub.cfg manually... and fails. I had to manually do a sudo update-grub.
Is there any way to fix this so its all updated automatically while leaving windows the top choice? No manual intervention required beyond clicking "install updates"?
Also, is it possible to JUST have the Windows and Ubuntu choices, no Ubuntu recovery, memtest, alternative(older) kernels for Ubuntu, etc in the grub menu?

I have just updated my Ubuntu linux to Ubuntu 10.4, not my grub menu isnt letting me boot to Windows Partition.The problem seems to be with grubs new update from using an editable menu.lst file to using a non editable grub.cfg file. Everywhere I look it states "DO NOT EDIT THE GRUB.CGF FILE". I am at a loss as what to do. I figured that the new configuration has screwed up the Windows Boot File. Anyone have any suggestions on how to fix this. I am not sure if it is a windows issue or an issue with the Grub boot menu.

I've been trying to get a dual-boot system with a truecrypted Windows partition and grub 2 in combination to work successfully and to date, I haven't had much luck. I'm using the grub 2 version from Ubuntu 10.04.2 LTS.I understand from searching through Google that there is presently no easy way to chainload the Truecrypt boot loader from Grub 2 in a similiar way that was done with Grub 1. This is because the Grub 2 payload is much larger and actually overwrites some of the Truecrypt boot loader, preventing it from starting.Does anybody know what might be going wrong here? I've been looking for ages now and can't seem to find any solution to this problem apart from restoring the Truecrypt loader to the hard disk and trying to chainload Grub 2 from Truecrypt. I'd rather use Grub 2 as the main loader though as Ubuntu Linux will be the main operating system in use.

I tried looking this up. It seems that in Ubuntu, you need to edit /boot/grub/menu.lst. I tried that, and the file is not present in Debian "Squeeze". (Just trying it out on a different PC, In case you are confused by my other thread regarding Lenny) So what do I need to do to change the default OS to boot?

First happened after the installation of VirtualBox OSE. Freezes right afterStarting GNOME Display Manager: gdm3and, in one instance, on the following line. Doesn't accept input and the cursor stops blinking on either state. VirtualBox's drivers are one of the closest lines to the last one and, in one instance, one of these lines reported an error. I can boot recovery mode and have already removed VirtualBox. Given it was installed with a live netinst CD image (on a USB stick) and I have a history of bad installations with this image, I'll try to install the normal CD image, although this will take some time.

I am using Debian Squeeze, having installed it after Windows 7, each on a separate HD.
What happened was that Win7 became unbootable and, after failing to recover it, decided to live without it.
After a (happy) week of Windows-free life, I'm wondering if I can safely remove GRUB ("Grub-pc" and "Grub-common" are installed) since, as far as I know, GRUB is there only to boot/load more than one OS?

When I netinstall debian squeeze an asus netbook using using Unetbootin usb stick, at the end I am asked if I want to install grub on MBR. I agree, yes, but on booting I find that the netbook has not grub. I go back to usb stick that stole my grub and I use it to boot. I go to sunaptic and install grub, still nothing, the netbook won't boot without the usb stick.

I recently did a single boot install of Lenny-xfce on a Compaq Armada laptop. There were no errors and grub indeed found that Lenny was the only OS on the hard drive and installed itself on the MBR. My problem is that I'm getting an error 18 when booting the freshly installed system from hard disk. I booted into rescue mode and started a shell to take a look around. There are files on the drive and /etc/grub exists. device.map shows dev(0,0) as being mapped to /dev/hda. A search on the forum for "grub error 18" came up with nothing.

I recently installed another Linux distro, Kali Linux, alongside my Debian 8 and discovered to my chagrin that my computer boots to Kali's grub rather than to the Debian grub. I had spent some time customizing Debian's grub and would hate to see that effort go to waste. Is there a way I can get my computer to boot to Debian's grub instead? I tried deleting Kali's boot partition with gparted but that did not seem to do anything.

I have installed Debian a few times now (and other distro's), so I'm fairly used to installing linux. I'm not used to installing it on Apple hardware (back in 2009 on my laptop I had some issues that were solved rather quickly, but that's about it). Now I'm installing Debian Squeeze on a new (well, bought today, but it is the previous model: iMac 11,2) desktop iMac.
Installing goes well (resizing partition, rEFIt, booting Debian 6.0.1a netinstall CD, installing packages etc.) I followed a tutorial [URL] to install grub explicitly with force after installing and running gptsync. Everything went according to the tutorial and I rebooted to be welcomed by rEFIt and then grub: perfect!
BUT when I chose Debian in the grub-selection list, I only see a few lines of starting the kernel, and then my screen goes all black. A few seconds later I hear a sound, and iirc it's the sound of gdm prompting to select a user. I cannot switch to a TTY and I have to use the power-button to shut the system down.

I'm trying to manually boot (from the GRUB console) into a system set up as follows: crypt partition -> LVM -> root LV, and I'm having some trouble figuring out how to do this from the GRUB console.
I have successfully manually booted a system which is set up as just LVM -> VG -> root LV. All I have to do is load the LVM module. In GRUB, that partition shows up as (hd0,gpt5). Once I load the GRUB LVM module, I can see the logical volume within the LVM as well. (My volume group name is "caesar", and the single logical volume is named "root".)
Code: Select allgrub> ls
... (hd0,gpt5) ...
grub> insmod lvm
grub> ls
... (lvm/caesar-root) ...
It's fairly simple to manually boot:
Code: Select allgrub> set root=(lvm/caesar-root)
grub> linux /vmlinuz root=/dev/mapper/caesar-root
grub> initrd /initrd.img
grub> boot
Where I am having difficulty is in trying to insert crypt before LVM. I can set up such a scheme, and put a minimal installation on it, without issues. It's booting into it upon reboot that I can't figure out. Once I load the GRUB crypto, cryptodisk and luks modules, I can mount the crypto partition:
Code: Select allgrub> ls
... (hd0,gpt5) ...
grub> insmod crypto
grub> insmod cryptodisk
grub> insmod luks
grub> cryptomount (hd0,gpt5)
Attempting to decrypt master key...
Enter passphrase for hd0,gpt5 (<long hex string here>): <type my password>
Slot 0 opened
grub> ls
... (crypto0) ...
At this point, GRUB sees the crypto partition as (crypto0). But the GRUB LVM module doesn't see "inside" of the crypto partition, so I don't see the root logical volume within the LVM listed; all I see is (crypto0).
Code: Select allgrub> insmod lvm
grub> ls
... (crypt0) ...
Setting it as root doesn't work:
Code: Select allgrub> set root=(crypto0)
grub> ls /
error: disk `crypto0' not found.
So, How do I get GRUB to "see" LVM inside the crypto partition?
