I have 74.5 GB partition on an 80 GB hard drive. I copied an ISO image of windows 7 and inserted into my DVD drive and installed it. But after installing I get a black screen and at the top it says "Missing BootMGR press cntrl/alt/del to restart. I went and restarted and pressed any key to boot from the DVD, I then chose english and pressed enter, I then pressed recovery and selcted to cancel and used the command prompt to copy bootmgr from the DVD to c:\ then restarted again. I am at a loss of what to do next, can anyone help?

Trying to reinstall windows 7 now copying windows files went find. It seems like it is stuck at 20% on expanding windows files now.

Your ISO image may not have included all the files found on the Windows 7 DVD.

As far I knew the Windows 7 DVD is a dual layered DVD.

I could be wrong about this, as I have not ever tried to create a copy of the Windows 7 DVD, even though, I have a retail copy of the Windows 7 Home Premium DVD.

So perhaps someone could share a little more light on the subject.

Not sure where you got your W7 ISO, but it may not be genuine, or even contain the boot files.

I have been able to make a backup copy of my W7 DVD without any problem. It boots into setup just fine.

It also fits on a 4.7G disc.

This may also occur if you have an external or portable hard drive plugged in. I noticed that on some gigabyte motherboards the boot order can sometimes be screwy. Try hitting F12, Escape, F10, or whatever your key combination is for selecting a boot medium, and then try selecting the drive you installed to.

Also, you can verify your image by comparing it's checksum with the ones published on Microsoft's site. To do this, you need a program that will allow you to compute the required hash. A good one that I like is "Marxio File Checksum Verifier" available here: http://www.marxio-tools.net/en/marxio-fcv.php

To generate the checksum, drag your iso file into the program and it will automatically compute a hash. Make sure you have the "SHA1" selected and then compare its hash with the one published on Microsoft's site here: https://msdn.microsoft.com/en-us/subscripti...ult.aspx?ppud=4

If you have not already re-installed using your windows 7 dvd follow the guide below it says vista but is generic and applies to windows 7 as well.


MrBruce don't think windows 7 DVD's are dual layed i have win7 ultimate it is only 3GB and have seperate disc for 64-bit os i'm in the uk so it may be different in the states.
