Ok sorry for spelling im doing this from my phones thouchscreen. The other day i devided to dual boot ubuntu onto my desktop. I ptoceeded to install alongside windows. However after that i could not boot windows from grub. Something about in an invalid efi. Fearing the worst i tried booting into my recovery partion but that went strait to my normal windows. From there i decided to use easybcd to fix my boot manger back to windows. After that i rebooted to find an error that there is no valid os entry point. Ive tried system recovery and install but both have said they are an invalid version. So after more googling i booted off of flashdrive into ubuntu and marked my main 800gb partion boot( before a small 128mb was marked boot?). Restarting it still said invalid os entry point and the system recovery says invalid version. Both the recovery and install are the correct 64bit. I really just need to get into a command prompt so i can run the commands to fix my boot. Any help would be apreciated.
