I have installed Windows 8 Pro x64 over my previous Windows 7 installation. However, I need to re-install Windows 7 on a second partition, in other words, with dual-boot functioning.
When I boot the USB, containing the installation files, windows 7 starts installing. When prompted what partition I want to use, I select a 40GB, NTFS-formatted, partition. Normally, here I should be able to click on the button "Next", however, the button is disabled and when I click on the link "Windows cannot be installed on Disk 0, partition 4", a Messagebox prompts saying:
Windows cannot be installed to this disk the partition contains one or more dynamic volumes
Next, I try using a VDISK. So I create one using the command prompt on the selected disk, attach it and when I refresh the installation, the disk appears in the list. I select the disk and next, it starts installing. However after extracting and installing, the following error message appears:
Windows cannot update the computer's boot configuration. Installation cannot proceed.
I have tried to run the 'Startup Repair' from the Windows 7 installation, yet the program responds by alerting "Startup Repair cannot repair this computer automatically"
I have looked all over the internet to find a solution, yet none have helped.
For any help you are able to offer, you have my sincerest gratitude.
