General :: Unable To Boot With Ubuntu And Windows 7 - Grub Bootloader Getting Removed

Sep 2, 2010

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.

Ubuntu Installation :: GRUB Removed After Windows 7 Boot

Sep 1, 2011

I'm running Ubuntu 11.04 and Windows 7 on a Dell Inspiron. On boot I get the GRUB menu listing Ubuntu (+ old versions) and Windows 7. However, if I boot Windows 7 all is fine until I reboot. On this next boot GRUB is gone and Windows boots. Ubuntu is still there, I can get into using my live-cd and 'repair' GRUB. After that, on booting GRUB is back and fine (including Windows 7). Does any one have an idea how to fix the booting/GRUB thing more constructive?

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 Install :: GRUB Chainloading Removed Boot-flag

Dec 13, 2009

I had my BIOS complaing that there were no OS. (worked since releaseday of 11.2).

partition setup:

sda1 : primary : swap
sda2 : primary : ext3 : Kubuntu
sda3 : primary : ext3 : opensuse (flagged as bootable)
sda5 : logical
sda6 : logical

opensuses GRUB is primary and Kubuntus is chainloaded.

The problem occurred after I tried to boot kubuntu for the first time since I installed opensuse. Kubuntu didn't boot. so I probably set up chainloading wrong. No big deal, this I can fix.

The big problem was that after trying to boot Kubuntu no OS was marked as "Boot" in MBR. This is VERY strange. somehow the boot-flag is removed!

After setting the boot-flag (with a live-CD) everything works again. I can reproduce this.

I've tried to find answers but could'nt find any.

Is GRUB supposed to remove the boot-flag when chainloading? have I found a bug?

Ubuntu Installation :: Restore Correct GRUB Boot Order After Removed XP Drive

Mar 11, 2010

I have an old Dell Dimension 4500 that, until recently, had 2 hard drives. One drive is running Xubuntu Koala and the other was running XP. I had set up Xubuntu to run LVM.

After needing XP again for a small project I tried reinstalling XP, got disk errors, took the drive out to just have Xubuntu, and now when I boot I get "Error loading operating system".

I have tried restoring GRUB from a Live CD with no help. Everyplace I look on the net talks about restoring GRUB after installing Windows on another drive. I'm trying to get GRUB working again after removing the XP drive.

Ubuntu Installation :: Windows 7 Removed From Boot Options?

Oct 24, 2010

I've had my laptop dual-boot with Ubuntu 10.03 and W7 for some time, and all has (mostly) been OK. Unfortunately, my windows installation was an upgrade from Vista, and always a bit of a pig's 4rse, so I deleted the partition and reinstalled it cleanly.

But now I no longer get a list of boot options, so I can't boot into Ubuntu.

Its partition is still there OK... I can get the dual-boot back...

General :: Cannot Install Grub,unable To Boot Windows 7?

May 31, 2010

Two days ago i turned on my pc and suddenly there was a message:"Minimal Bash-like line editing is supported.For the first word,TAB lists possible command completions.Anywhere else TAB lists the possible completions of a device/filename.ESC any time exists...

When i googled this message it came out that this has got to do with linux (i have never used linux and i formated my disc once or twice since i bought it so i found it very strange that this problem is related to linux).Anyway,i found out that grub is the problem and that it isnt a big deal to solve it.I downloaded Ubuntu,booted it from the cd and followed the instructions...I typed in grub (in the terminal) and it told me to download it so i typed in "get-apt grub install" or something like that and it all went well,i was now in the grub directory.Then i typed " find /boot/grub/stage1" and it told me that the file was not found.

I have tried everything,i have downloaded the super rescue cd the fix the problem but i have still the same problem.

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.

General :: Put Windows Xp In The GRUB Boot Command For Mint?

Apr 3, 2010

I have Microsoft Windows Xp installed on my Primary Drive C: and I had a Mint boot disc that I would pop in and load from. Well I got tired of this disc and installed a new hard drive in my computer so I could use Mint as a secondary OS. Everything went good in the install, and I put Mint on the second drive. But when I boot my computer the GRUB menu only shows Linux Helena Mint 8 to load from and no Xp. Xp is still currently installed on the computer in the Primary drive, but how do I inlcude it in the GRUB boot menu or boot it at all?

General :: Windows XP Won't Boot With Grub After Installing Ubuntu 8.04?

Jul 8, 2009

I am completely new to Linux as of today.I finally took the plunge and downloaded and installed Ubuntu 8.04 on my Windows XP computer (dual boot), using the Ubuntu installation wizard to "make room" on my hard drive for Ubuntu by creating a separate partition. The installation finished successfully and Linux boots just fine, but Windows XP will no longer boot at all.

I have read many threads on this and other sites, giving advice of how to correct this problem. I am not at all experienced in editing and working with different ways of booting (other than Windows default). But after some frustration, I located (according to the threads) a couple places to try making changes to the boot commands and I tried various lists that were suggested. Before I changed anything, the Windows XP boot screen would appear and then it would revert right back to Grub.

[code]....

what drive number Ubuntu and/or Grub installed to, or assigned to the Windows partition, and I have no idea how to find out. I do not have a Windows XP installation CD (it came pre-installed on my computer), so I CANNOT wipe out that partition and simply reinstall it--I MUST be able to fix the problem without harming Windows!!! I also have data in the Windows partition that I don't want to lose. I could possibly uninstall and reinstall Ubuntu (as I saw suggested somewhere online), but I have not the slightest clue how to accomplish that task--and WHAT IF it didn't work?

General :: Removed Ubuntu - Can't Get Windows To Load Now?

May 9, 2010

I installed Ubuntu 10 over the weekend at the request of a friend. Unfortunately it doesn't work for everything that i use my system for daily. So i called my friend and asked him how to remove it. He told me to boot to the cd and delete the partitions and then use the windows cd to fix the master boot record. Piece of cake, until I deleted the partitions and remembered Windows 7 doesn't have a recovery console to repair the boot record....

So now I'm stuck with my computer booting up and showing a grub rescue> prompt and nothing else. I called my friend and all he said was way to go, you're screwed now. Is there a way to fix this without losing everything in my windows installation?

General :: Boot - Updated, Grub Menu Not Booting To Windows Partition?

May 24, 2010

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.

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.

General :: Editing Grub.conf To Make Windows Default In Dual Boot?

Mar 31, 2010

I installed Windows XP Pro and RedHat Linux Enterprise 5 on my PC for my purpose. The PC is used by other family members too and they need only Windows OS for browsing. It is becoming problem for them to reboot after the PC enters into Linux by default. I am still learning Linux and I want to edit the /boot/grub.conf file to make Windows as default OS to boot. The following is the content of my grub.conf file (FYI):

#boot=/dev/sda
default=0
timeout=10

Ubuntu :: Get The Version Of GRUB / GRUB-legacy To Boot Any Recent Windows 64 Beyond XP (Vista Or 7)

Dec 20, 2010

I've been using Linux for over a decade, so no need to worry about the obvious. I'm positive that I have my partitions/install correct. What has me baffled is that Fedora 14, which uses GRUB 0.97 (GRUB legacy) - boots Windows flawlessly every single time on the same hardware, but Ubuntu's (or the upstream Debian's) GRUB legacy do not - even though they are based on the same upstream code from the GNU Savannah servers.

No matter what I've tried I cannot get the Debian or Ubuntu version of GRUB/GRUB-legacy to boot any recent Windows 64 beyond XP (Vista or 7). All that it does is resets the computer when Windows attempts to boot, without an error. GRUB is notoriously difficult to compile, so before I try to compile code from RedHat's archives - any thoughts,experiences, similar issues - whatever?

Ubuntu :: Windows 7 Won't Boot - Displays Windows Logo And Then Drops Back To The Grub Menu

Jan 9, 2010

I have a Compaq Presario CQ60 with Nvidia GeForce 8200M graphics card. When I first installed Windows 7 followed by Karmic in dual boot I could boot into both OS. Now when I try to boot into Windows, it displays the Windows logo and then drops back to the grub menu. It may have started happening after Windows 7 installed updates. I tried reinstalling both Windows and Karmic again and it again worked initially but now Windows no longer boots. Does anyone have any suggestions about what may be causing this or how I can fix the problem without reinstalling?
