When trying to install windows 7, I get the error " The installer could not install to an existing system partition due to insufficient free space ."

It also does not work to create a partition if it is deleted.

Answer 4

You have an empty space at the beginning of the disk> 4GB.
Create an empty 100MB partition in it (or 350MB if you plan to upgrade to Win8+ in the foreseeable future) and make it active.
Do via diskpart:
Shift+F10
diskpart
select disk 0
create par pri size=100 (or 350)
active
If the partition will be created after the existing partitions, then create par pri size=100 offset=0 or 1024

I faced such problem. I must say right away that initially my disk was formatted and there were no partitions on it. The following worked for me in this case: I simply deleted all the boot and backup "small" partitions on the adjacent first drive.
