BOOTMGR is missing

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. Why is this so difficult to resolve? Can anyone help me get this fixed?

Disconnect every hard drive you have, both power and data cables, except for the installing drive. Then clean install 7 again, reformatting as usual. Connect the hard drives once 7 is installed.

Hi. Startup repair will help you out. You may need to run it more than once or twice consecutively.

Windows 7 is finicky if there is more than one hard drive hooked up to the motherboard when doing an install of the OS.

I usually just disconnect the data cable at the motherboard and never had any issues. Never had any problems leaving the power cable attached.

Maybe cause I'm lazy and don't want to take of both side panels of my Lian-Li case.

A curious bug to have, question to be asked is why? Something introduced in 7 or did Vista also have this issue? XP never did. Just shows that no matter how much testing is done before retail only real world use will show up the issues.

Not really. His HDD are probably not in the same config as the first install, so the installer chose the first available drive it can find and placed the boot files there. Maybe he has a usb flash drive in now that he never had in the first install. When booting, it looks elsewhere and not the usb stick, as an example.
There's absolutely nothing wrong with Windows 7 installer. I beta tested every leaked and official version there was on many machines. In fact, all my machines have multiple drives and must have installed 2-300 times. In fact 2 of my machines are upgraded with every leak/release. That's like 20 or more of them. They run as perfect as I've even seen in my life and never had a single issue yet from upgrades or clean installs. It all in the users' hands.

I have had the same experiences as TorrentG. Never a problem under an circumtances. It was a particular pointer from Microsoft, during the Beta testing period (Which was the same for Vista, fwiw).
In partial answer to Mychael. It was innovative, for Windows 7/Vista. L nux have had it for many years, (I am not a lnux user!) The MBR, which Vista Windows 7 rewrites, is, right or wrong, dedicated to Microsoft Windows 7. Personaly, in Linux and Windows 7, I think it is a bad feature and plays havoc with backward compatibility in different Oss
Fwiw. The OP says he is installing, afyter a format, on the same drive, so the reason for his problem is a mystery. Only offer I had is he selected the wrong drive for the installation, and the old OS is still sitting there, with the boot manger overwritten. TorrentG's solution should do the trick (hopefully!), otherwise Easybcd willl sort it out.

Look, I don't why this is, but every time I have tried to install Windows 7 with more that one hard drive connected, it won't install.

I have checked several forums and lots of other users are having the exact same issue. Once the extra drive(s) are disconnected, 7 installs like a breeze.

TorrentG if you know a "workaround' for this, I would like to know, plus many others. I'm not being facetious either, it's a P.I.T.A. whenever I want to reinstall 7 and have to disconnect the extra drives.

My post was meant with sincerity, Nibiru. Honestly, I install a few time a week on various diffrent environments. I have not experienced the problem and am sorry that I cannot give a solution.

Same here, no problems. Worst case scenario, you can throw a few simple bcd commands to move the boot files (System partition) location to help things. Involving bcdedit /export
