I got this message today after cleaning out the inside of my computer. Didn't really mess with anything. Booted into Windows XP just fine, had to restart for an update. Burg loaded, I selected Windows and I get:
"NTLDR is missing. Press CTRL-ALT-DEL to restart." WTF? Windows breaks itself. Great. My ubuntu install works just fine. I have 2 separate hard drives, with one OS on each. I can't access the other drive from ubuntu. It says
Unable to mount location Error mounting: mount exited with exit code 13: Index entry out of bounds in directory inode 5. Failed to mount '/dev/sda1': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details.

Finally got Ubuntu installed on my machine and now I can not get windows to boot from GRUB.My windows partition is located at /dev/sda2 and here is my menu.lst file.When I reboot my computer GRUB will not load. It always gives me Error 21. The only way to get it to run is to turn the computer off and then back on.When selecting Windows 7 from the boot list the first time or two it will just send me back to the list after a brief blank screen then around the 3rd time I select it, it tells me NTLDR is missing.

My CPU is i5 760, motherboard is GA-P55A-UD3R, and VGA is GTX460. I installed the WINXP as my first OS with no problem and the performance is nice. Then it turn to CentOS5.4, everything seem good during installation. However, when the installation done and first reboot, I meet problems like "NTLDR missing", so both of WINXP and CentOS can't boot.

Six months ago I installed Ubuntu 10.04 to my otherwise Win XP work laptop. I decided to continue to use Windows' boot loader as primary: I told the Ubuntu installer to put grub2 onto a separate partition, then used dd to copy the first 512 bytes into a file in my Windows C partition, then edited boot.ini to link to it - its a common technique that is described in many support forums and blogs. This worked fine, and continued to work until a few weeks ago. One day I chose the Ubuntu option at the Windows boot loader and got a blinking cursor at top left of screen and no grub2 menu. I was able to use SuperGrub2Disk to discover and boot from my grub2 install - so that didn't appear to be broken. I finally fixed it by dd'ing a fresh copy of the first 512 bytes of my /boot partition over to the Windows C partition. So somehow the Windows boot loader decided it no longer liked my original dd'ed file.
The only things I can think of that might have changed and caused this to happen are (on Ubuntu) an update to security packages using the graphical update manager that pops up (I rarely do a command line apt-get upgrade/dist-upgrade and certainly not in this time frame) and (on Windows) a Windows Update - as it is a work laptop I tend to take whatever essential updates it suggests. As you can see I managed to fix the problem. However does anybody have any similar experience or any explanation why this may have happened? Could an over-zealous Windows Update have caused it?

I recently installed Ubuntu and wanted to remove the Windows XP installation is was dual booted with (I used Wubi to install Ubuntu), but I ended up just editing boot.ini to remove it from the boot menu and automatically boot in to Ubuntu. But then, Ubuntu started playing up and keeps on popping up with the Critical Temperature warning, saying it's 80-100C although it's the first time it's been turned on in 14 hours... But to add to my confusion, when I try to boot from ANY disk, it comes up with "NTLDR is missing" and a restart message.

I am trying to install ubuntu 11.04 from a live cd on a recently formatted 80gb hard drive. Ubuntu seemed to hang and become unresponsive after waits exceeding 40 minutes. As I had some difficulty creating the media, burning the iso to disc, I attempted to install a couple other distros, mint and xubuntu, to see if they worked. These displayed the NTLDR missing message and prompted me to restart.
PC: pentium 4 2.93 ghz processor
80 gb hd
512mb RAM
lite on dvd/cd burner
There is a working 150gb hd with xp on it set as the #2 hd in bios. I would like to install a linux-based os on the smaller drive, preferably ubuntu, but am growing a little impatient. Is there a bootloader or anything I will need to install, and what should be the final configuration of the two hard drives once I get another os installed on the hd dedicated to it?

I have a machine which i have to test with a live version of ubuntu 9.10. I used a usb pendrive for some time but it failed after rebooting a few times. Now i try to install a live version on a external HD of 160 GB.
I installed the ubuntu 9.10 with unetbootin on the external HD. When I boot from the HD I get the error: NTLDR is Missing. Is it possible to install of load the ubuntu 9.10 version on a external HD. I found some stuff about
- using another USB stick with the live version and install from that USB to the external HD.
- using the live cd to install. But I don't have a CD drive on the machine.

I don't know what kind of problem it is. seems strange. I was used to using windows xp previously. Recently, i installed Ubuntu 11.04. i used ubuntu more than windows- rarely i peeped into windows. BUT, 3/4 days ago, when i tried to run xp, it only shows a message(on a black window/screen):
"NTLDR MISSING PRESS CTRL+ALT+DEL TO RESTART"
If i press ctrl+alt+del, it only restarts and if i again try to run xp, it shows the above message again; BUT windows xp doesn't run. i don't know what to do.

I have installed Ubuntu 9.10 on my system. At the time I wasn't very familiar with boot loaders and I just left everything default at installation. Now I have the following setup on the hard drive:
- MBR: GNU GRUB
- Partition 1 (dev/sda1) Sony Vaio Recovery Partition
- Partition 2 (dev/sda2) Windows XP Home Edition
- Partition 3 (dev/sda3) Extended Partition
- (dev/sda5) Ubuntu 9.10
- (dev/sda6) Swap Space
I want to replace GNU GRUB in the MBR with NTLDR and add Linux to the NTLDR boot menu but from what I understand I have to install GNU GRUB to the Linux Partition first so NTLDR can chain load it to boot Ubuntu. I have heard of using the ' grub-install ' command in which from what I understand I should use it like this ' grub-install /dev/sda5 ' but I'm not sure.

I first installed 9.10 from 9.10 Live CD to my Thinkpad X200 selecting not to install its bootloader thinking I could use NTLDR. That did not work at all. Tried bootpart, starting 9.10 from LiveCD to reinstall grup... I gave up and in WinXP, deleted the 9.10 partition and its SWAP partition.
I reinstall 9.10 again into the now freed space.This time I selected to install the bootloader but to /dev/sda5.After completing the installation,I rebooted to WinXP and used bootpart to create the necessart ubuntu.bin and instructions in boot.ini.That did not work. I went into 9.10 live CD again and use dd command to extract the fir 512bytes from /dev/sda5 and place it in a USB drive as ubuntu.bin.Rebooted into WinXP and put this new ubuntu.bin into C:. All I get when booting into Ubuntu is a blank screen...

I have just installed ubuntu with a USB key, I have Vista installed in drive C: and I created a partition (L: ) and installed Linux root (/ ) in that one.When there was the screen where I could choose the boot loader i left the default option instead of choosing Windows Vista Loaderand now I can't boot Vista anymore.
In grub i see a windows vista option, but that option brings me to a recovery partition and not to the real operative system. I know that vista is not broken because when I used wubi I was able to boot from the vista bootloader without any problems, but I never could boot vista from grub because it brought me to that recovery partition.I can access all my files on the disk from ubuntu, but I would like to be able to restore the vista boot loader and use again windows when I need it.Is there a way to restore vista's boot loader? I tried to do automatic startup repair from the vista recovery cd but it says that no problem could be found.

I recently upgraded to Ubuntu 10.04 and everything was working fine. Last week I was away from home and when I returned, my wife told me that she cannot boot in Ubuntu. We have used dual boot for Windows Vista and Ubuntu. Now only Windows was working. So I created a LiveCD from Ubuntu website and tried to boot.
I can boot using LiveCD. Then I tried to install grub. I forgot exact commands I found online, but something to do with /dev/hda1) and now everything is messed up. It does not show boot menu (to select OS) at all. It only shows grub> window. I believe that the OS on the computer is alright, just the boot option is gone. I do not know how to get back the grub.
When booting from LiveCD,df /boot shows filesystem as aufs (no idea what it is). If I go through File browser, I can see the windows files and my Ubuntu installation. So I believe OS is okay, just not the boot loader.

Just installed Lucid on dual boot machine, Linux is OK but tried booting to Windows XP from grub2, missing hal.dll (this is apparently a common problem and I found many many posts on this topic). Boot.ini contents below:

Searching for solutions, looks like most appropriate solution is to load the Recovery Console from XP setup disk, delete boot.ini, restart the Recovery Console and run:

I had a dual boot system(WinXP and Ubuntu). But something happened and I was not able to boot into my Ubuntu partition. It gave GRUB missing error. I tried reformatting the dedicated 40 GB ubuntu partition to NTFS and again try to reinstall ubuntu. But now, when I install ubuntu through boot time install, it shows that my whole hard disk is empty( but I have windows XP on whole hdd at the moment) and do not give any other option but to use whole hdd.
Alternatively when I try to install it inside windows, then after rebooting it shows, no root file system defined error and neither gives any option to do so also ( this method worked earlier o my PC). At the moment, It still shows ubuntu and windowsXP at OS choice menu at boot time but when booting in ubuntu, it shows GRUB missing. (I don't have any ubuntu installation on my hard disk at the moment).

I am completely new to Ubuntu/Linux and am having trouble getting my DVD-ROM drive to work. I've tested a few things, and it seems that if there is a CD in it when I boot, then it works fine, but if there is nothing in it then Ubuntu won't list the device. The DVD-ROM is master on a PATA cable and the CD-RW is slave (yes I know it's getting old now...) Drives worked fine under Windows XP. I don't know very much about the boot process, but the following from kern.log seemed relevant: Booting with a CD:

I had installed Fedora 13 on an unused partition of my ATA hard-drive yesterday. The primary OS here was Windows Vista.
Anyway, everything was working fne for coupla hours after which I had to restart F13 for some reason. This is when all the trouble began ..
Fedora wouldn't boot cause of some "power issues" - there were none. Windows Vista wouldn't boot because "BootMGR was missing"
I figured if I removed Fedora using the live CD - format the partition, it would help. It didn't. Well, atleast the partition got formatted. I tried re-installing F13 from the live CD but it doesn't finish the process - saying a command, something to do with 'shutdown' is not valid.
I tried repairing Vista from the Installation DVD but it is unable to do so.
Right now, on rebooting the computing, I enter the 'grub' console. I tried using grub commands to boot "Windows" from the (hd0,0) partition like thus,
Code:
grub> rootnoverify (hd0,0)
grub> makeactive
grub> chainloader +1
grub> boot
But it still maintains that "BootMGR is missing" .

I used the update manager to update the kernel and whatever the other recommended updates were yesterday. I shut the computer down overnight and now when i try to boot into Ubuntu 9.10 i get a basic grub shell and when i try commands like "boot" it tells me there is no kernel loaded. I installed Ubuntu with Wubi so it is a dual boot system.
I've tried to access the Linux volume with a live OpenSuse 11 CD but there is no device to mount. It sees the entire hard-drive as if it hasn't been partitioned. I don't necessarily need to fix the installation. I just need to get my files back.

I have a Dell Dimension 2350 with an Intel 82845G Graphics controller that is connected to a 15" Craig flat screen television via VGA. It has absolutely no issue running at the television's peak of 1280x720 at 60 Hz with Windows XP. When I first discovered Ubuntu, I immediately tried to install it. After a tedious month of failed attempts, I resolved to doing what I opposed: using Wubi. I did not want to use Wubi because I wanted Ubuntu on a separate partition.
This is where my issue is. After installing Ubuntu 10.04 Lucid Lynx, I rebooted and started normally. I noticed that audio was present but all I saw was a blank "No Signal" screen on my television. I waited for over an hour, to no avail.computer was responsive. This was obvious when the computer released audio when a button was blindly pressed. I reinstalled after waiting even more, suspecting a failed install. I then used the failsafe graphics upon pressing escape after my third failed install. This worked, but it gave me an unsightly 640x480 resolution. I did my best to fix this, but it came to a dead halt with an error I could not fix: a CRTC error.
I then installed Ubuntu 9.10 Karmic Koala without an an issue. Everything was perfect except for the fact that I did not have the most updated Operating System even though it was free. I decided to to update 10.04 via Update Manager, thinking that all would go well. It did not. My mistake in updating brought me back to the drawing board.My official Ubuntu 10.04 Compact Disc arrived in the mail yesterday. When I hit "Install" I eventually end up at the same "No Signal" screen

just recently, while attempting to boot to windows 7, i happened to select the wrong boot option by mistake, that is the windows 7 recovery (something like that, cant remember it specifically, but the word 'recovery' is there). the option has been there eversince i installed ubuntu 11.04 on my system, of which i cant find the answer as to why it existed there. so once i selected it (which was by mistake), it took me into some recovery process which i abandoned as quickly. it restarted and the windows 7 option was no longer there. the windows 7 recovery option, however, is still there. How to get my windows 7 boot option back?

I just netinstalled Squeeze to a netbook with Windows7. The installation went well without any problem. Linux is also working OK. When I boot now, grub does not show Windows7. I took default settings during installation. I mean I did not do anything special. What should i do to fix it? Should I run osprober and grub-update?

I have read a number of threads relating to the bootmgr missing issue but I can't seem to apply the fixes to my specific situation, any assistance is most welcome; my details below. I have two HDDs
1 x IDE HDD running Fedora 12 which is allowing me to write this,
1 x SATA HDD which has win7 premium 64-bit, and up until the Fedora 12 instal, was the only OS.
Grub gives me two options for boot, they are: Fedora Other When I select 'Other' I get hte message :BOOTMGR MISSING My assumption is WIn7 located on my SATA HDD = Other what I might do to allow Win7 to boot.
