Hey guys,
I have an issue, yesterday I was about to install Windows 7 without using a USB flash drive by shrinking Drive C, and allocating a special small space enough to put the windows installation file in it. So in order to boot into the installation, I had to mark it as active.
The problem was (Thanks to my stupidity), that I've forgot to make the ISO file bootable in that partition, and instead of that, I've transferred the ISO as it is into the partition.
After I've restarted my PC, it obviously stated an error that I have no OS available etc.
What can I do in order to mark the system partition as active again? Or at least ways to use command prompt while on boot?

Thanks.
