BootMGR is missing + Keyboard not detected

Microsoft Windows 7 home premium

Specs: Windows XP
Yesterday my computer had a major crasch and I couldnt get it to

start as it couldnt find my keyboard. Ive been using the W7 version

but I was gonna formate it to XP again due to the problem. So I HAD

TO use the "repair" choice as I couldnt select the other as my

keyboard wasnt responding at all..

Everytime it failed to repair the problem and I couldnt enter BIOS as

it didnt detect my keyboard at all. However, while I was in advanced

mode after repair failed, it worked which was way odd. I tried the

repair about 30 times with failure at the end everytime.

I tried system restore using 3 different points at least a dussin

time each with no success at all.

So in the end I had to use CMD and I got it to format. Once it was

done I restarted, but I still had the same "Keyboard not detected"

and then I got "BootMGR is missing"
"Press Ctrl+Alt+Del to restart".

I dont know what could be wrong as the keyboard worked after I got

into the repair mode and in cmd.
But not in the startup to get into bios. I've tried with both PS2

Keyboard and USB and USB through PS2 switch, with and without my

mouse, nothing works.

What could be wrong? Could it be
the mothercard or the Hard Drive?
What should I do to get this fixed?

Please help me out

Thank you.

The problem with your keyboard is probably that it is a USB keyboard which your BIOS does not have drivers for. Hook up a PS/2 Keyboard and you should be good.

The problem with Windows is that a repair alone will not do it. You have to boot in Recovery Console and at the command prompt "c:>" type...



This may or may not work. This is a serious problem and you may want to get expert help to prevent data lose. If you don't care about the data then just format the drive and reinstall Windows.

Well, Ive tried all kinds of keyboards.

I was using a wireless PS/2 keyboard from the beginning.
So I tho it was being gay, so switched it to usb, that didnt
work, so I used a USB-to-PS/2 Switch, which didnt work either.
I then tried a old regular PS/2 keyboard and that didnt work.

I was using W7 and that repair tool is different from XP.
However, in there I was able to get the keyboard to work.
Both in CMD and in the System Restore area.

I wonder if it might be the mothercard that is fagging up or
if its just the harddrive being a bitch?

Thanks for you reply tho.

PS: I tried both those commands "fixboot" & "fixmbr" but neither worked. I even looked up on
different sites to find different command paths to
use. But nothing.

PS2: I cant format the computer as I cant get the
keyboard to work and the cd wont boot on its own.
I have no clue as to what to do to get my computer
formated. :/

Oh, yuck it does sound like the Motherboard is having a PS/2 problem. If it was me I would take the drive out and install it in another computer that does have control over the BIOS.

If you where sticking with Windows 7 then you can make a bootable System Recovery Disk (Which has a Windows Kernel with USB drivers) from Windows 7 backup manager (One of the nice new features in Windows 7) but XP does not have this. For XP boxes I use a store bot systems disk call Symantec System Recovery 7.0 which boots a Windows Kernel with drivers along with drive utils. You can get an open source Linux System Disk and format the drive. I recommend Ubuntu...

Good luck...

Hope you didn't hot plug a PS/2 keyboard into the PS/2 port. You need to boot with the PS/2 keyboard connected.

But you CAN boot to another device : USB, CD, floppy ... for that you would not need a keyboard, since there is no key pressing required to actually try and start booting into it (unlike the press-key-to-boot-from-WindowsXP-disc)

Um didn't I just say that TVC? I think the problem is that he can not use the keyboard in the BIOS settings nor the Windows Boot in order to reformat.

Also from the posts I think the OP is at a level of computer understanding not to have left the cable unplugged when booting but it is a good first step trouble shooting. He might have even plugged the cable in the mouse port instead of the keyboard for that matter.

Well. I only have the PS/2 for keyboard, I have none for my mouse. I didnt remove it at all when I restarted. I tried different methods to get it to work but none did.

Also, I'm using Sata HD and my other computer uses the old
kind and isnt compatible with this one, so Im screwed either way.

I could have it taken to someone who has a sata and could
have it formated over there and then I'd just put it into my
own once the formate was complete? I wonder if that might

But wouldnt the keyboard problem still remain as it seems
to be a mothercard problem? I think what Ace said could
be correct, some type of glitch?

I did have problem with the motherboard from day one when
I bought it. The store I bought it from wouldnt replace it and
2 of my sata ports have been fawked up ever since.

I've been considering buying a new mothercard and harddrive
anyhow, but its still kinda sucky as I will have to wait at least
2 months to even afford it. :/

I appreciate all the help. You guys are the best.

"Also, I'm using Sata HD and my other computer uses the old

They have PATA/IDE to SATA convertors I think for about $10 that will allow you to hook up your old drive to a new system. I think Best Buy sells them, let me check...

The use of a PS/2 keyboard has no relationship with what type of hard drive you are using. You have some other issue.

Does the PS/2 keyboard work in the start up screens? Test by entering the BIOS (setup) screens. If it doesn't work there then it isn't going to work in Windows.

Go back and explain why you attempted to repair the Windows installation. If you hae a hardware failure the OS isn't going to make it work.

While in startup it doesnt work but once you get pass
it the keyboard works without a problem.

I cant enter bios.

I will try using my friends computer to put in Windows on the
harddrive and then place the harddrive in my computer.

This should solve the problem with startup and should also
solve the keyboard issue as it goes passed the begining
and I wont have to use the keyboard at all.

If this doesnt work out, I'll just have to buy myself another
mothercard once I can afford it.

That isn't going to work.

Are you using a PS/2 keyboard that is connected to the purple PS/2 port without any adapters?

Yes. But I also have one with USB.
Even if it doesnt work it cant hurt anymore :P

So either it works or Ill have to wait 2 months.
Whichever way Ill have to wait 2 months so. :P

Installing Windows with your computer installed in a different computer will end up with the hard drive not booting and you will be right where you are.

Describe the major crash and what led up to it. Then tell us ALL the steps you have taken since then. Did you clear the CMOS by chance? If not, don't. That will make a USB keyboard not work in the start up screens.

Did you ever connect a PS/2 keyboard while the computer was running?

It sounds like you have experienced a hardware failure and that is the reason why things are not working right.

Watch the POST screens at start up and identify every hardware item that is configured there.

Also, open the case and disconnect the hard drive cables from the hard drive and then try to boot.

Do you have ANY external devices connected to the computer at all except for monitor and keyboard? If so disconnect them all. No USB drives, flash drives card readers, webcams, etc.

No, I didnt disconnect or connect the PS/2 Keyboard while
the computer was running. I was tempted to tho.

I think Ive erased the windows on it through CMD.
But Im tired of the crap comp anyways. So I'll give it
a try :/. He has a similar computer so Ill take a chance.

I appreciate the advice tho.

I think what OtheHill is saying that if you format the system on another computer and install Windows from that system that when you go to put the drive back into yours it will cause Windows to go into a constant reboot because the drivers that will be installed by the plug and play will be for the other computer and Windows might not boot on yours.

You just don't want to supply any requested information do you? Knowing what happened when you crashed may help diagnose the problem.

What kind of keyboard connection was in use when the computer crashed?

Are you running as I specified in #13? I am not a mind reader. If you don't tell us something then we can't assume.

It worked out perfect. The "Keyboard not detected" still remains
but I think that is a glitch in the mothercard.

Anyhow, the computer works better then before and it will
last at least 2 months so I can get money together to buy
a new mothercard :).

Thanks alot for all the help.

I have a similar problem also with the exception of the key board not detected. I am getting

"BootMGR is missing"
"Press Ctrl+Alt+Del to restart".

it was supposed to be a simple reinstallation of the OS but it turrned out very bad. The computer (belongs to a friend of mine) had win XP on it, plus it had over a ton of virus and bad registery entries so i started to do a fresh installation. My friend said he'd like win 7 on it so i used a copy on his, booted from the cd. I reached the advanced option to select the drives to install the OS. I formatted successfully and then installation started. About 2 mins into installation i got an error stating cannot read drivers from source. I thought that maybe my CD was scratched bt got same problem with a clean copy. I then tried to install with XP SP3 but the disc was not beng detected. ( It kept saying OS cd not detected insert correct cd and press enter) i tried Vista installation, it got detected and then when i got to advanced option screen.....there were no Harddrives or media sources!!!!!) I checked it out online and the told me to try formatting the drive ( i took it out and connected it to another computer and tried formatting there, it took about 15 mins formatting and then told me formatting was uncessfull. I tried it in disc management and i was told formatting cannot be completed!. when i checked back the status in My Computer, the harddrive had no space allocatons! (the harddrive is partitioned into 2) and both had zero space available. So i was ready to declare the drive crashed...but comes a surprise.....i tried it back a couple hours later and believe it or not both partions were able to be formatted!!!) Anyways i connected it back to the computer i was fixing, tried loading an OS installation...and now i get the message ........

"BootMGR is missing"
"Press Ctrl+Alt+Del to restart". !!!

I am quite fed up with this harddrive plz replay as fast as possible.
