windows cannot be installed to this disk mbr partition error
I had to replace my motherboard and after putting all the part in place, tried to repair windows 7 from the installation disk. It wouldn’t work. I kept getting an error about the disk already containing a master boot record. I tried a clean install which also didn’t work. Really glad about that, since the repair did work after following instructions from http://thessdreview.com/Forums/motherboards/2310.htm
I’m hoping that my easy fix will help some others who are Googling for answers.
When I dropped my Win7 disk into my Sony optical drive and re-booted, I had no way of knowing that the BIOS set up a second drive labeled “UEFI Sony Optical”. All I knew was when I reached the disk choice option I couldn’t install Windows.
During one of the re-boots, I realized that my boot order had changed. I saw “UEFI Sony Optical”, so I went into the CD-DVD Drive options and now saw “Sony Optical”, listed just under “UEFI Sony Optical”. All I did was change the drive in the #1 Boot Order field to “Sony Optical”, hit F10 to “Save and Reboot”.
This time when I hit the “choose disk to install windows” screen, there were no error messages, and I could install Windows on any of my drives, just as I had done for years.
I don’t know if everyone’s fix for the issue would be the same as mine. But it’s sure worth a try. Just make sure that you are not trying to run your Windows disk from any optical drive that says “UEFI”.
I hope this helps some one out there!
Thanks Hameister! You probably saved me days of work.
I was able to change motherboards and went from AMD to Intel with just a windows repair and adding the new drivers. So cool!!
