So yesterday i came across the problem where i deleted my 50GB partition that was reserved for Linux. I was thinking at the time i should reverse the boot loader over at the Ubuntu terminal, because the way i got into Ubuntu first time about a week ago is if i setup the bootloader to launch grub via command from Windows CMD, and it actually took me to the GRUB Screen so i was able to launch linux from that, but long story short i didn't think of reversing that in the terminal and after deleting the Linux partition in windows and restarted(WHICH I WAS SO STUPID, i knew the consequences was coming to me), i messed up my EFI boot loader and i couldn't get into windows anymore, and i tried every single Boot rec and BCD command out there on the forums of different variety websites. So how can i avoid screw ups like this is in the future so i don't have to reinstall windows cleanly on my SSD? And Also, the Linux partition was separate from 1TBB HDD, so it wasn't even near my SSD windows installation at all, but i still had to reinstall windows and i couldn't really successfully fix the windows boot loader.
