Ubuntu Installation :: Windows 7 Not Recognized And NTLDR Is Missing
Mar 22, 2010
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.
I need to know how to get fix my windows xp system without messing with Ubuntu. I can get inti Ubuntu but on windows it says NTLDR is missing dose anyone know what I can do because I still use windows once in awhile so it needs to work.
i don't remember what i did with this old lap top of my, i remember i installed linux on it, then reformatted the HD to NTFS trying to installed windows. I believed it was successfully installed and never used it since. just recently, i brought it out and want to install ubuntu. now when i turn it on, it just give me NTLDR is missing error message.i have tried putting the window XP cd in, using the ubuntu live cd, tried the "ultimate boot cd" trying to erase the whole drive and repartition.
I am also wanting to install on a laptop which is about 2 years old. I get the error message "ntldr is missing" when it boots up and doesnt recognise the disc even though it is set to boot from cd first!
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.
I am brand new to Ubuntu and i tried to dual boot winxp and unbuntu 10.04 and the first time failed so i had to reinstall Ubuntu both times thouh i got an error when trying to boot xp that said NTLDR is missing press ctrl alt delete to restart and now i cant access windows
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 am trying to load RHEL 5.2 into VMWare 6.5 running on (dare i say it) XP SP2 As soon as it boots from DVD I get "NTLDR is Missing".Does anyone know if this a RHEL related problem, a VMWare problem, or an XP problem? I just need pointed in right direction.
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.
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.
Recently upgraded to latest ubuntu release, dual booting windows and ubuntu. Got the gist of ubuntu quickly, thought to go ahead and delete the windows data in my partition. Evidentally didnt have it partitioned correctly, as the next time I rebooted, I recieved an "NTLDR is missing Ctrl+Alt+Del." message. I cannot reboot from a bootpatch usb/cd, as I took out everything pertaining to windows allready. However, I know that this can't be a hardware problem. Is there a way to fix BIOS to operate from ubuntu? Or did I pretty much hose myself?
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...
In my system, I had installed windows XP first and had deleted one of the partitions (made free space.I am not a techy. I dont know the exact term). In that space, I have installed PC Linux OS (Linux). Now, I want to use that free space to Install Ubuntu by removing the PC Linux OS. When I boot with the live CD of Ubuntu 9.1 to install, in one of the steps, it says the system does not have any OS. It neither recognises windows nor the other linux. Kindly help me. What should I do now. Could I manage to install Ubuntu without completely formatting the system all again.
I have a HP g6t, previously fully running 11.04. I wanted to root my HTC evo 4g so I decided I *needed* to install windows 7. I created a 20GB partition with gParted, then downloaded and burned .iso of windows 7 my laptop came packaged with (windows 7 home premium 64-bit). However, after installing, Windows now refuses to recognize ANY of my network drivers. This means my ethernet connection (was plugged in during set-up) as well as my wireless card.
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 have installed ubuntu 10.4 as a dual boot with Windows 7. I thought, because of a previous experience, that my music and pictures were ok in the windows file system because I would be able to access them. Well I can't. I don't even see the the Windows c: drive. I know its still there because I can boot windows.
So what do I need to do to make the c: volume / drive reappear.
Was already having Windows 7 and ubuntu 10.10 and i installed ubuntu 11.04 with removable drive. Unfortunately, my windows 7 boot option is no more in menu. how my menu.lst looks like..
I dual booted Ubuntu with Win XP, and decided to upgrade XP to Win7. Thought I knew how to do it, so excuse my dumbness. Here's where I'm at: I booted GParted, and deleted the /, /home and swap partitions, making unallocated space. I expanded Win XP partition and tried to re-boot, expecting only Windows to show. Instead, I got the Error 22 error when Grub was the first thing to load. So, back to GParted, deleted the primary partition, created a new bootable partition, formatted it NTFS, and put the Win7 disk and rebooted. This time I got a Windows error "can't load NTLdr".
Rebooted the computer without the disk, and got the Error 22 again. So it seems (?) that I'm not able to change/remove or otherwise, the Grub boot file. So the drive is currently useless, unless someone can tell me how to get the disk back to a bootable state where I can load Win7, after which I can create Ubuntu as a dual boot again.
I used to have Windows XP Professional on my computer, then I decided to install Ubuntu but it didn't work for me it gave me really weird errors, I thought I uninstalled it, and then I installed Debian on my computer, Debian ran smoothly but when I tried to start Windows the GRUB from ubuntu appeared and when I tried to start windows again it showed and that the hal.dll was missing, I reinstalled Windows but still the same error appeared, this also affected my Debian GRUB so I had to install it again, I don't know what I should do in this case. How can I delete ubuntu's GRUB for good? I've already formatted my windows partition but it keeps using Ubuntu's GRUB.
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'm testing out 10.04 on one of my partitions, and I love it. I have been using it exclusively for a while now, I have not logged into Windows since! Really don't care about windows anymore!However, yesterday I went to boot into windows... and I noticed the option to choose it is missing from my list! Maybe I'm just not getting to the correct list? The list I get shows like 5 different modes and versions of Ubuntu and something called Windows Recovery (which does nothing), but that's it.
So I have a single hard drive with two partitions, and I am trying to install a dual boot of Windows XP and Ubuntu. However, I am having an issue installing the Windows XP component.
I keep getting an error along the lines of a missing/corrupt hal.dll after the first restart in the install. This has happened every time I tried to install windows XP, from several different discs, all of which I have confirmed to work on another computer.
I have tried several things for fixing this, from repairing the MBR and boot.ini to replacing hal.dll from hal.dl_, and nothing works. However, Ubuntu 10.04 installs and boots properly.
I just installed fedora 12 on my laptop. fedora is booting and working fine, but the problem is that now windows isn't booting. when I try to boot windows i get the next message:
"BOOTMGR is missing"
I looked at /boot/grub/menu.lst, and those are the lines for booting windows:
"... title win7 rootnoverify (hd0,1) chainloader +1 "
then i checked with fdisk -l and verified that windows is actually installed on the second partition (sda2).the next thing i tried was to use the repair option at the windows 7 installation DVD. the problem is that when i try to preform a startup repair, the installation DVD doesn't recognize my existing windows 7 installation, and therefore wasn't able to repair it. if it's relevant, here are some more details on my machine:
HP probook 4310 windows 7 64-bit fedora 12 32-bit
i have one sata HD which I devided into 6 partitions {a system partition of the laptop, windows 7 (NTFS), swap, /boot (ext3), / (ext4), /home (ext4)}
