Ubuntu Installation :: Dual Boot Using Windows Boot Loader, Not GRUB?

Nov 8, 2010

I'm trying to dual boot Win7 and Ubuntu WITHOUT using Grub. This is to support Bitlocker encryption.

I followed this guide, and now when I select Ubuntu I get a Grub> prompt and no ubuntu.

I feel like I'm halfway there, I just need to get Grub to load correctly or something.

General :: Grub Boot Loader Installation In Dual Boot Machine After Windows 7 Installation?

Mar 23, 2010

I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.

Debian :: Grub Boot Loader On A Dual Boot System?

Dec 16, 2010

This is the third time I try unsuccessfully to install Debian as a second OS on a hard drive. When it gets to the end of the installation process the installer asks whether I want to go ahead with the Grub Boot Loader, I choose yes. The end result is however that I can't boot that partition within the hard drive -- i.e., Debian. Can someone tell me what is going on? Should I not use the Grub Boot Loader when I have more than one operating system on a machine? Should I not install Grub on the Master Boot Record (MBR)?

Ubuntu Installation :: Windows Boot Loader And GRUB ?

Jun 14, 2011

I installed Ubuntu 11.04 64-Bit via Wubi but it seems that when I turn on my machine I first get the Windows Boot Loader, when I select Ubuntu from the list it then goes into GRUB with the option to select Ubuntu or Windows. Is there any way to change this so only GRUB is used?

Ubuntu Installation :: Grub Load With Windows Xp Boot Loader?

Jun 8, 2011

I installed Ubuntu 11.04 on a separate partition, with Grub being in it own partition. When I start the PC only windows Xp is available. So how do I get grub or Ubuntu load with windows xp boot loader? I tried with Live cd, the sudo grub but then it says command not found. I think its because Ubuntu 11.04 uses grub 2.

Ubuntu :: Use A Windows-based Recovery Partition On A Dual-boot Computer To Overwrite Partition And Remove GRUB Loader?

Mar 9, 2010

is it possible to use a Windows-based recovery partition on a dual-boot computer to overwrite the Ubuntu partition and remove the GRUB loader? For instance, if you booted up your computer, accessed the hidden recovery partition and used it to reset the computer to it's factory default settings, would that effectively remove the Ubuntu partition and the GRUB loader? Would a completely new installation of Windows overwrite/uninstall Ubuntu and GRUB automatically?

Fedora Installation :: Dual Boot With Xp - Grub Can't Boot Into Windows?

Jan 10, 2010

I just set up a dual boot on a system with fedora 12 and XP. XP in on one hard drive (sda) and Fedora on a second hard drive (sdb).

I installed grub on the Fedora disk so as to not touch the windows disk at all.

Prior to installation, in the bios, I set the Fedora disk (sdb) first in the boot sequence, and then XP (sda) so that the grub loader would boot up by default. (If I set the windows drive first then the system bypasses grub and loads straight into windows.)

My system can now boot up into Fedora fine, but if I select windows from the grub loader menu I just get a blinking cursor - windows will not boot.What do I have to do so that grub can boot into XP?

Ubuntu Installation :: Editing GRUB Settings - Set Windows 7 64 Bit As Default OS In The Boot Loader Instead Of 10.10

Jan 18, 2011

I am a new Ubuntu user, and I am attempting to set Windows 7 64 bit as my default OS in the boot loader instead of Ubuntu 10.10. I have entered the command gksudo gedit /boot/grub/menu.lst into terminal, and the menu.lst file does open. However, this file appears to be completely blank, which does not seem to make sense and is preventing me from changing the boot order.

General :: Emergency GRUB Loader CD For 64bit Dual Boot

Aug 9, 2010

Installing upgrade from Open SuSe 10.3 to 11.3. I did it on a 32-bit laptop, aborted half way through and couldn't get back on because GRUB loader was corrupted. No problem as there are lots of 32-bit GRUB loaders available for download, install was successful 2nd time. I need to do the same for a desktop x64bit dual core Intel. Can't find a x64bit GRUB loader on internet - how do I extract from my current set-up an emergency GRUB-loader CD?

Fedora Installation :: Repair To The Grub Boot Loader To Boot Into Win 7 ?

Oct 23, 2009

I have XP, Win7 Pro and F 11 installed. Before I installed F 11, Win 7 boot mgr was working fine. I then installed F 11 and I went to System/Admin/bootloader to edit it and it wouldn't bring up the boot loader. In the attachment was the error msg. Now my only option when I boot up is F 11.

I do not have access to the Win 7 DVD only the F 11 install disk since I am on a fishing trip and need to use Win 7. How can I repair to the grub boot loader to boot into Win 7?

Ubuntu Installation :: Grub For Dual Boot (with Windows 7 Pro)?

Jul 8, 2011

11.04 installed on free space I had setup but it didn't install Grub2 for a dual boot (with Windows 7 Pro). It may have gotten confused with my disk setup. Drives and their groupings (Windows lingo):

- Windows 7 Pro on C-drive (appears to be sdb2), it is a SSD
- The free space was setup on this SSD and Ubuntu is located on sdb5 (Linux) and sdb6 (swap space).
- Applications stored on D-drive (RAID0 with 2 small SSDs using RST (Intel Rapid Storage Technology).
- data on a RAID card using HDs in RAID0.

Small wonder it got confused, if that is the problem. I have a LiveCD I can use to boot, is that the best? What are the commands to install. Is there a better way?

OpenSUSE Install :: Dual Boot Loader Gone After Windows Reinstallation

Nov 19, 2010

had a dual boot system with openSuse 11.1 and Windows XP working OK - Linux boot loader was where OS selection was made (openSuse was installed after Windows) Last week I had to reinstall Windows and this removed the Linux loader from MBR and Windows booted automatically. I wanted the Linux boot loader back,checked the threads about boot loader restoration and did the following:

- downloaded Knoppix 6.2.1 ISO and burned to CD
- booted with CD
- opened terminal with root privileges and typed:
grub (ENTER)
grub> find /boot/grub/stage1 (ENTER)
> (hd0,2)
grub> root (hd0,2) (ENTER)
>Filesystem type is ext2fs, partition type 0x83
grub> setup (hd0) (ENTER)

setup was successful (no error messages)

Now when booting, i have an error that root (0,3) can not be mounted and "Press any key to continue"??? When hitting any key I see that there is GRUB there with all entries as in original state (Suse 11.1 and Windows) but only Windows can be booted. Then I downloaded live eval of openSuse 11.1 and did the same (booted from CD and run same commands from terminal as root) - again no errors but still "root (0,3)" can not be mounted..

Ubuntu Installation :: 32 To 64 Bit - Dual Boot With Windows 7 - Messing Up Grub

Feb 19, 2011

I'm running 10.10 32 bit and would like to reformat to 10.10 64 bit. However, I am dual booting with windows 7 under grub. I've had some crap experience (my fault) with grub before and would like to make sure I have a plan. I've downloaded the 10.10 64 bit. Can I simply boot and install 10.10 64 bit without concern of messing up grub? Horror story: Installed ubuntu once before with dual boot and somehow grub couldn't find windows

Ubuntu :: Missing Grub And Dual Boot Menu - Windows Won't Boot

Jul 3, 2011

i am having a problem with my dual boot setup. I originally installed windows XP on a 100gb hard drive, from there i downloaded and burnt ubuntu off so i could install it on my 200gb hard drive. For a little bit i struggled to even get it to install because it wouldn't recognize my onboard nvidia graphics, i ended up having to get an alt boot disk and fix it with technique in this link:

[URL]

Now after the bios boot, my screen shuts off for awhile and takes me directly to the login screen for ubuntu. No Grub, no windows boot options, nothing. I tried booting windows by choosing it from the bios boot menu but all it does is hang at prompt and doesn't boot at all. I tried the live cd fix and reinstalled grub but nothing changed. What i think is happening is that it boots the Grub menu but it doesn't display it because of graphical confrontations. It hangs for about 10 seconds, the grub default time, and then turns my monitor back on to display the Ubuntu login screen.

Ubuntu Installation :: How To Boot 10.04 Via Windows XP Boot Loader

Jul 28, 2010

I have 2 HDDs:

HDD 1 (sda) with Windows XP installed on sda1 and four more partions.

HDD 2 (sdb) with three NTFS-Partitions (sdb1, 5 and 6) and Ubuntu 10.04 (sdb7) + Swap-Partition (sdb8).

I would like to boot Ubuntu using the Windows XP boot loader, i.e., having an entry there to choose Ubuntu and start my installation of Ubuntu 10.04. I have installed Ubuntu 10.04 on sdb7 and told the installer to install the grub2 boot loader to /dev/sdb (should it have been /dev/sdb7?). When using the boot selection option of my bios and choosing the second HDD Ubuntu starts without problems.

I used dd if=/dev/sdb of=bootsect.lnx bs=512 count=1 to copy the mbr of my second HDD and copied the file bootsect.lnx to my c: drive. Then added C:ootsect.lnk = "Ubuntu Linux" to my Windows boot.ini. When rebooting my computer I get the option "Ubuntu Linux" in the XP boot loader. Choosing it I come to a black screen with a blinking white cursor. All I want to do is not use Grub 2 as my primary boot loader but instead leave my WinXP installation untouched and start Ubuntu from within WinXP boot loader. This has been working just fine with my old Ubuntu installation.

Ubuntu :: Grub 2 Boot Loader Stopped Working Windows 7 U9.10 / Cause Of It?

Feb 5, 2010

I recently installed ubuntu 9.10 32 bit using live cd onto a recently new Dell machine with windows7.

Everything was fine for a couple of weeks, but last night I got the error code...

Looking into the forums, I see that maybe I need to re-install grub 2. When I started probing using fdisk, I saw that the boot partition was my windows partition. So, I thought I would ask to find out if this looks right before I start making things worse code...

Fedora :: Grub - Lost Windows Boot Loader?

Aug 10, 2009

I just installed Fedora 11 (I installed over the Fedora 10 installation I had already installed)..

-Before I would have Grub give the choice of Fedora 10 or Windows (Where Windows would load the Win Boot loader for my options of Windows 7 and Windows Vista)

-NOW: I have the same options.. But when i select Windows (It loads the Recovery partition) instead of the Windows Boot Loader...

Here is my fdisk -l

Device Boot Start End Blocks Id System

Partition 1 does not end on cylinder boundary.
/dev/sda2 192 5414 41943040 7 HPFS/NTFS

General :: Incorporate Windows Boot Loader Into Grub?

Oct 23, 2010

I have triple booted Windows XP (195 GB)partition 0? the second partition is Windows 7 (195 GB)And the rest of a 1TB hard drive went to Open Suse 11.3. if it makes any difference I used g parted to create the three partitions and made them all primary. My problem is I want to change the way they all get along. When I boot up, I get the options;

Desktop -- openSUSE 11.3-2.6.34-12
Failsafe -- openSUSE 11.3-2.6.34-12
windows 1
windows 2

which is fine, but clicking on windows 1 takes me to the windows boot loader with the options of windows 7, or previous version of windows. clicking on windows 2 brings up a screen telling me " rootnoverify (hd0,1) chainloader +1 BOOTMGR is missing press ctrl+alt+del to restart" I would like the end result to be windows 1=XP,windows 2=7, then I can rename them accordingly. one more thing, when I installed openSUSE, I let it automatically configure the hard drive and create the necessary partitions(it deleted partition 3 first). i remember it saying somewhere that the boot manager was past the 125 GB limit, and might not boot.

Debian Installation :: 8.3 And Windows 10 Dual Boot GRUB EFI Removed

Feb 3, 2016

I've been using Debian for a few years but always on dedicated boxes and/or VMs.

Finally decided to dual boot Debian and Windows on my main Desktop PC.

Installed as I normally would using, however this time using a seperate drive (one for the existing Windows 10 install and the other for Debian), Debian install detects that windows has an EFI partition and sticks an entry in there, which is fair enough, and everything working fine. Then I spent some time configuring all my software and set it all up just the way I like it. I've rebooted Debian a few times to check it's working correctly and it is.

The issue arrives when I reboot and load into Windows 10. It boots fine.

However after a further reboot GRUB no longer loads... and the machine just boots directly into Windows 10.

After doing some further digging into my EFI partition (and reinstalling various times) it would appear that after a reboot Windows 10 deletes the entry GRUB creates in my EFI partition after EVERY reboot.

Done some googling and most people advise turning off 'fast boot' in Windows as it locks certain partitions to facilitate the machine going into hibernation, only to find that it's always been turned off on my machine (I recall due to a driver issue with my graphics card this had to be turned off when I installed Windows 10).

I've found this article on the Ubuntu forums : [URL] .... however I've tried their steps and windows is still doing a hostile takeover of my EFI partion after a reboot!

Any way to stop Windows 10 from interfering with my EFI files after a reboot? (without doing the obvious thing and kill Windows off).

OpenSUSE Hardware :: GRUB To Dual Boot 11.2 And Windows XP But Hangs On Boot

Apr 20, 2010

HW config is: AMD Athlon 64 X2 5000+ Black Edition, MSI 785GTM-E45, 2X 1Gb Kingston HyperX PC2-8500. I have set up GRUB to dualboot openSUSE 11.2 and WindowsXP. Initially i had set up system with defaults: CPU@2600MHz (200X13) and therefore RAM@800MHz. Both openSUSE 11.2 and WindowsXP worked just fine. Memtest86 found no problems.

But after a while i decided to change this setup to: CPU@2500MHz (250X10) and therefore RAM@1000MHz, as it promised better overall performance. And now Windows still boots and works better then before. Memtest86 still can't find any problem. But openSUSE 11.2 hangs at boot. I've suspected cpufreq governor, but changing from Ondemand to Conservative in /sys/devices/system/cpu/cpu0/cpufreq doesn't help.

OpenSUSE Install :: GRUB Boot Loader After Re-installing Windows XP ?

Mar 21, 2011

This is a problem when Windows is running some malware that cannot be removed, which happens all the time. The problem is all the new hardware or specialized hardware will not work on Linux so Windows is the only choice. I would think the latest versions of Linux would have this problem worked out by now. I installed 11.3 one week ago, only to find that the repair option in the install menu no longer exists so don't bother uses this link to reload the GRUB HowTo Boot into openSUSE when it won't Boot from the Grub Code on the Hard Drive. I also tried this link Re-Install Grub Quickly with Parted Magic which does not work either. On step 2 typing grub returns the error message "grub command not found". You can use GRUB if you boot the install DVD and select Rescue Boot. However when you type find /boot/grub/menu.lst the error message "file not found" is returned.

I did the following to restore my GRUB boot record. Boot the install DVD and select the update option during installation. Change all the repositories to enable except the NVIDIA repository, it is not responding at this time. When the system comes up go into Yast and open the boot loader. It should have your original boot menu in memory. Change the default to another option and re-write the MBR. This will write a new MBR using the original data updated with your new default. Re-boot and then change your default back. I am just a NewBe so this may not be exactly correct but I hope it saves someone like me some time fixing a MBR re-writing by the Windows installer.
