How To Fix The BOOTMGR Is Missing Error
Sep 30, 2012
I'm very sure, especially if you've ever installed a second HDD on your computer yourself you have seen this message. BOOTMGR is missing Ctrl+Alt+Del to restart.Basically when it says to restart it is assuring you no treatment will work, WRONG! this is one of the easiest problems ever to fix, if you have your Windows 7/Vista installation disc.First step - Boot from installation mediaSecond step - Go through everything until you find a button that says "Repair your computer"Third step - Let it run though, on the first time, it will not find a WORKING operating system, restart when it prompts and boot the disc again.Forth step - Repeat Second step, and now your OS should be listed, click on it and run Startup Repair.Fifth step - Do NOT boot from disc, because it should now be fixed.this i have only tested on 7, idk if this completely complies to Vista)

I recently decided to move a hard drive I've had in an external enclosure to inside my case. After I did this I got a bootmgr is missing error on startup.
Things that may be useful to know:
I have 3 hard drives (this new one being the third), one 60gb for my operating system, one 160gb for other junk, and now this 1tb one I've just put in.
My 60gb operating system drive is connected using an IDE cable, the other two using SATA cables.
I've checked all plugs and connectors in the case.
I've checked the boot order in the BIOS, sometimes the 60gb drive doesn't even show up, sometimes it does. My boot order is CDROM, then HDD(60gb one obviously). So startup will go like this: Bootmgr is missing, go into BIOS, check boot order, HDD not showing up, restart, Bootmgr is missing, go into BIOS, HDD is there, exit and startup ok. except sometimes I have to restart it a few times before it'll show up.
If I have posted this in the wrong thread, then let me know which would be the best thread to post in and Ill move it there.
Update: Just crashed with a blue screen, it restarted itself but now I'm getting "a disk read error occurred" message. I restarted it and I got "Bootmgr is missing" again.

Managed to break my PC again in my usual form. So I recently bought a new SSD and did a fresh installation of Windows 7 on it. Everything boots fine - until I get nitpicky about the boot times and start changing some settings in the BIOS. To give some background, I was initially trying to resolve a problem with slow boot times on my GIGABYTE P55A-UDL3. There is a 10sec delay after the "Loading Operating System" message. Windows splash screen onwards only takes 5 secs. I read somewhere that this had to do with having the CD-Rom as the first boot device. (Don't even want to get started on the AHCI BIOS itself already adding another 2-3secs) Anyway, if I recall correctly I did some (supposedly harmless stuff like) moving my SSD to the #1 priority in the BIOS list and also set Hard Disk as the first (and only) Boot Device. Boom. BOOTMGR is Missing.

My computer recently began to give me bsod and would not detect external devices, i.e. external hard drives, wireless adapters, and other usb devices. The issue windows gave me as the cause was that these devices did not have digital signatures. After online research and a trip to the geek squad, I determined that all of my hardware was in perfect working order. I tried to remove and re-install my copy of windows 7 64 bit ultimate but found that my disk was, despite being unscathed, unreadable and unusable.
I found several articles about creating a bootable USB drive with an ISO of the disk. I have the ISO on my laptop and have been trying to get my USB to operate on the desktop, which due to blue screens and automatic restarts gave me no recourse but to wipe it completely. As I stand now I have partitioned the USB drive as fat32 after doing a cmd prompt cleaning and have loaded the iso on using several different programs including the official Microsoft USB creator. All but one have produced the same error saying "error loading operating system" when booting from just the USB. The only program to produce a different result was YUMI which loaded a program that launches on start up and gives me the option to use the Windows 7 ISO but then produces another error saying "Error 27: Unrecognized Command"
Have I missed something in the formatting process or does the fact that the Windows USB creator re formats the USB as NTFS before every ISO upload mean that I cannot load my copy of Windows 7 this way?

My pc didn't boot, so I used a SATA --> USB docking station to format my hard drive (NTFS). Then I took an old hard drive, and transfered all of it to my new one.
Now I get the BootMGR is missing error when I boot my pc.

Recently I have had a load of hardware issues which have caused me to replace my PSU and GPU. After doing so to more powerful units, I went to boot up again and got the error: "BOOTMGR is missing"
I have had this before when I remove my secondary HDD and just try and boot from my primary SSD, but after re-connecting the secondary HDD it would work again (telling me this BOOTMGR is on the HDD, even though the Windows files are on the SSD).
I don't know what to make of this as if I boot from the SSD alone nothing happens and it restarts, and if I connect the HDD and it boots then it goes into the System Recovery and after repairing/restoring still won't work. I think the BIOS settings are correct, with the SATA drives set to AHCI (as I'm 99% sure they were before).
My PC specs are:
Intel i7 980X
Intel DX58SO Motherboard
128GB OCZ Vertex 3 SSD
2TB WD HDD (secondary)
Radeon 7850 2GB GFX
8GB DDR3 RAM
Windows 7 Ultimate

I have had number of errors, the latest being 'Error number: 0x80070017' when trying to install windows 7. I'll start from the top. Originally I had problems exactly the same as on this thread below, incl same model PC except with Vista, also USB mouse often freezes or stops working: [URL]. I ignored the problem until crash during online streaming (assumed problem was to do with graphics card), usual multi coloured horizontal lines on monitor, repeating sound. Manual push button shutdown.
On restart, black screen no boot activity. Recovery DVD doesn't work/ don't have all the discs. So I bought Win 7 upgrade instead. Now I have a combination of 'BOOTMGR is missing', and when that doesn't occur PC freezes on any screen you can think of. Sometimes I can get all the way to 'expanding files' when installing Win 7, then I get Error number: 0x80070017. I have tried copying DVD to USB drive (in case it's a dvd drive speed problem), but then cannot copy the whole DVD usually there's an error stopping me (on another pc).
Also no OS available to select during repair system selection on Win 7 upgrade/install screens. Finally error regarding 'USB drive unplugged during boot' or something to that effect, also tells me DVD or CD or hard drive might no be connected properly. Had that message twice, again locks up. I've checked inside, every thing connected.
So to summarise:
Bootmgr missing (on boot)
Error number: 0x80070017 (on Win 7 install)
No OS available to select (System repair)
Constant freezing

I made the HDD formatted and it's in NTFS format. The disk for some reason says Bootmgr is missing. Also when I try to install Windows 7, it says error code: 0x80070017. I don't have any OS installed. I've tried the repair disk thing. Also my BIOS is PhoenixBIOS (or something, that what it says on the BIOS Setup Utility menu) and I don't know how to disable AHCI mode.

my sister has Sony Vaio E-Series which runs windows 7 Home edition. She encountered a problem starting up the windows and decided to use Recovery Disk, Recovery Disk stopped working and needs additional source (disk) to run. She weren't successful so decided to stop recovery and run it again. After that the error "BOOTMGR is missing" appeared! When I put the recovery disk inside the machine it doesn't work. F8 and F4 keys also don't work. So I can't use the similar solution mentioned on the internet like running "system restore". She also doesn�t have Windows 7 installation disc to run.

So I was doing the steps in this thread, and I came to the point where you set the partition to 'active. However,I accidently turned my computer off and now it tried to boot from that partition and it gives me the error message "BOOTMGR is missing" because I literally don't have anything on the disk yet. No Windows 7, nothing.
My question for you is: Can I change the partition that is being booted in BIOS or how do I change that?

I just did a re-installation of Windows 7 x64 on my computer, and I am getting the dreaded "BOOTMGR is missing" error. The previous operating system was also Windows 7 x64. I have 4 internal HDD, but I am reinstalling to the same drive that I originally used. I reformatted the drive when I did the installation.I have done a lot of searching on this topic to try to find a solution. I'm amazed at how common this error appears to be, and yet there doesn't seem to be a clear and consistent answer for solving it

I just got a computer for free, a Dell Studio 1555. When I got it, it would try to boot, then come to a screen that said that bootmgr.exe was missing. Sometimes I got a message that said something like mpio.sys was corrupted or missing. I have a Win 7 disk, so I put it in and tried to repair the installation. Each time I ran it, it said that the repair had failed. I tried to reinstall windows 7, and It made it to the first restart in the process. It showed the "Starting Windows" screen, but the colors of the windows logo never appeared, then I got the missing bootmgr screen. I decided to install Ubuntu and see if that worked, and it did (I installed it alongside the Windows installation). It was Ubuntu 10.04. I thought, "OK, so i'll just use this as a Linux machine"...and I decided to go back and reinstall so that I could use the entire hard drive. It never worked correctly again. Each subsequent time that I installed Ubuntu, I was told something along the lines of "Gnome Power Manager did not install correctly" and got a slow and choppy Ubuntu installation.Tried to install 11.10, and it failed completely. I opened the Ubuntu live from my usb drive, and opened the disk utility. I now cannot format, reformat, partition, or delete partitions on the drive. Is all of this just a case of a hard drive on its last legs, or is there something else going on here?

Today I got my new laptop and decided to dual boot Ubuntu and Windows 7 on it. After everal hours of partitioning and researching, I ran into many issues. Eventually I decided to boot Ubuntu from a USB drive, open up Gparted, and delete any and all Linux partitions while expanding the size of the Windows partition back to normalnfortunately, in the process, I must have made an error, because now upon startup I get the "bootmgr is missing" error. I don't have a recovery CD nor does my laptop have a CD drive, so that's out of the question, but I know for a fact my Hard Drive has a recovery partition on it. I want to restore my computer back to normal, keeping my old files if necessary. However, since I just got the computer today, I clearly don't have anything on there I can't afford to lose, so if I must do a factory reset I will.

My husband's comp crashed...he had Win7 Os. Recovery did not work! I tried to reintall Win7 got as far as formatting the hard drive. I then reinserted the cd to reinstall and now all I get as far as "Press any key..." I press a key and "BOOTMGR MISSING" press ctrl + alt + del to restart. Of course this doesn't work.I have reset the bios so that cd-rom is the only bootable device. It will not move from the bootmgr missing screen. The cd is a legal bootable copy, the hard drive and dvd player work I have tried them in another comp.System Configuration[CODE]

Her computer is an HP laptop it is runnung windows 7 . I have created the recovery disk( 32 bit) from online as that is what most sites said to do. After it said it was loading the windows files I clicked next. Then it said system recovery options.In the box it says (recovered) 292135 MB (d Local Disk. It is checked on use recovery tool taht can help fix problems starting windows. I click next. I get a pop up that says this version of system recovery options is not compatible with the version of windows you are trying to repair,So then I made the 64 bit recovery disk & restarted. I was unsure if it was 64 bit or 32 bit to start.

First off, why is reinstalling windows 7 such a pita? I've done it several times and it's soooooooo bad. With that aside, tonight I was attempting to reinstall 64 bit from 32 bit. I reformatted my hd using dos because advanced recovery simple does not work. After formatting and restarting I'm getting te bootmgr error. After reading countless threads with fixes nothing is helping. I CANNOT get past this error. I have the disc in, it won't go past the error. Pushing f2, f8, and f12 does not work. I can't do anything in the bios. Most of the solutions simply assume you can get PAST the error.
The next step I tried was unplugging the hd I formatted and installing to a different hd. This gives me an error of missing a device required. At this point I have no idea what to do besides maybe reformatting the hd again using another pc. Is there a recovery program I should dl to a blank cd?

I have a very big problem with my reinstall of Windows 7 Pro. I have now lost the bootmgr and am not able to "see" my SSD. Ouch! I searched the forum for my error: 0x800704f and couldn't find it nor could I get to see my SSD and am therefore not able to use the tutorial to "get it back." Well, I am at a loss at this point. I was originally trying a fresh install of Windows 7 pro. But, just prior, I got an error box that the Catalyst Control Center was not working properly(or something like that). But, when after all my efforts seemed to take me further down the rabbit hole. I concluded that I must post this thread!I built it myself and know just enough to make me dangerous!
