Hello! I tried messing around today with my personal computer, win 7 ultimate, UEFI and got stuck after a reset. I got a missing bootmgr error, asking to press ctrl alt dlt to restart so I put a flash drive of 7 ultimate for system recovery to try and fix that. The startup repair said it cannot repair automatically and in the details it says MissingBootManager. Can't use a system restore, I got an error saying "You must specify Windows installation to restore". Image recovery says error 0x80070002. After that I went forward to try and fix it with CMD but bootsec can't find c:\boot I tried rebuilding with BOOTREC /REBUILDBCD but that when it finds the Windows installation asks if to add it to the boot list it says "The requested system devide cannot be found". Any help would be appreciated, I'm really growing desperate here... A quick edit, right now I checked in the bios some boot settings (motherboard is a Asus b150m-a/m.2), both the hard drive and the flash drive disappear when I choose to enable both UEFI and Legacy but show up when I choose Legacy only, not sure if it helps...
