Windows 7 "no bootable disks found"

Dear Apple Community,

My iMac (Mid 2010)(with cd-drive)could not boot into the windows partition. What I do normally is that I press the alt key while I turn on my imac, and then boot into windows 7. However, today when I press the alt key, only the Macintosh hd partition is bootable, with no option for windows 7. When I tried to boot into windows 7 using startup disk in preferences, the computer boots into a black screen with "No bootable device, insert disk and press any key". How can I boot into my windows partition again? This issues started when I created a new partition from the left over partition of Macintosh hd without any changes to my windows partition i.e. I have a 500 hdd previously I had created 250 gb partition for windows and Mac OS each but after creating a partition of 50gb I got stuck on the above mentioned problem I reverted the partition back to it's original 250 gb partition but nothing changed. Plzz help asap.

Thank you!!!

iMac Pro, macOS Sierra (10.12.6), null

Ok I decided to delete my windows partition and create a new one I took all the important files from the windows partition as it was accessible from the Mac side and reinstalled windows. The only thing I wanna know is that can I copy files from the Mac partition directly to the windows partition as it is just a normal partition for Mac OS on the desktop ?? If I can are there any side effects???

Thank you

The macOS NTFS driver, by default, only allows read access. Boot into Windows, and you should be able to copy files to the Windows folders, provided your macOS partition is HFS+.

CoreStorage and APFS cannot be read using the default drivers. You can copy files to an external FAT disk from the macOS side, and then boot into Windows and copy the files. Do not use this method to transfer Windows programs, which should be re-installed.
