    Help with boot loader, deleted boot partitions.

    The other day i deleted my EFI partition along with one other, the reason for this is because i was trying to get a Ubuntu dual boot to work. Before doing this i knew i was going to brick my windows installation. But now i really need to get my windows partition back up and running because i need to access some very important files. You might be thinking at this point 'oh that is stupid why would you do that?' and i will say because i thought i would be able to fix it relatively easily, obviously that is not the case.

    some other side notes:

    The only partition that remains is the windows partition that contains the operating system and files.

    I appreciate any help you may be able to give.

    Are the partitions gone or Just erased ? and now unallocated space? or did you just overwrite the Windows Boot loader ?

    Need alot more details , I think before too many could help you...

    Startup reapir for win10 USB?

    If it won't boot try a MiniToolPartition Wizard Boot Disk (make on another PC) and see if it can find your Partitions and recover them.

    No point really guessing anymore ....you get the idea...

    I don't know Ubuntu so can't really help as I don't know what you were doing or how far you got with that....

    You have to be careful with some third party partition managers and a UEFI install since they may not do UEFI..

    Replacing the partitions is easy if you have a way to boot into a command prompt, such as a Recovery Drive or Install Media, as Kbird mentions..

    We will need to know the exact situation of your system and you can get that as well as replace the partitions using Diskpart.

    Ubuntu will install fine and even use Secure Boot if installed as UEFI. But getting a Boot menu is not that easy and would require Grub. I like to leave them as individual installs and select which one to boot from a Boot Device Menu during boot.

    On another pc, install Macrium Reflect Free, and create a Macrium Rescue usb drive or dvd.

    Boot from it, select Restore Tab, and click "fix windows boot problems".

    it should list Windows 10, and if so, click next, finish.

    With luck pc will now reboot.
