I apologize as this I'm sure has been asked several times,it just seems I can't figure it out, I have win8, win10 and ubuntu, I installed debian once, before win8 I had win7, well, I add my boot repair log, any help/advice/explanation as to what can be done is much appreciated,
If possible I would like to know how to reinstall/the specifications (fat32 or what) and where to install/reinstall grub to solve a problem if this happens in the future
well, many thanks for the information shared in the answers section, I was able to recover win10, not win8 but I can now dual boot win10 and ubuntu, I used diskgenius, to create the MS reserved 16mb partition, 100 mb efi fylesystem partition and used a recovery boot cd/dvd tool and used the command:
bcdboot C:\Windows /l en-us /s k: /f ALL
disk letters need to be checked first
I found many websites with instructions but I did know what I had to fix, until I fixed all of the above I was able to boot my pc again (did not know windows used 3 partitions, ms reserverd, efi abd C:), I had to install ubuntu on its own HDD to be sure it was going to boot, many useful commands are found here
