'I am going to have to do an install to remind myself of exactly what it says on the partitions page. I thought it would ask you where you wanted to install Windows and you would highlight the unallocated space and would get a message about creating partitions.
I get a little confused going back and forth between 7 and 8, but in 7, if you did not want a 100 MB system partition, you needed to preformat the partition. When you do the install next time, or before, try using Shift+F10 to open a command prompt and run diskpart. Create a primary partition and format in ntfs using the quick flag. Windows should then install on that partition. You may have to refresh the Partition's window to get the drive scanned again for any updated configuration.
Diskpart
lis dis
sel dis 0
clean
create par pri
format quick fs=ntfs
active
Where the disk 0 is shows as being disk 0 in the lis dis command.
Then try it again. You can only skip the System partition if you are not using a UEFI configuration, so I assume you are using Legacy (MBR). It has been many years since I have done a Windows 7 Legacy install, but I think I still remember how...
