jaclaz Posted January 7, 2016 Share Posted January 7, 2016 Thanks for replying, i have that partition, it's called System. Do i need to copy the files to that partition? If so, can you tell me what are the files?Well it is a bit more complex than simply copying a few files. The default (or "failover") EFI boot files are: \efi\boot\bootia32.efi <- for 32 bit UEFI \efi\boot\bootx64.efi <- for 64 bit UEFI For windows you will need to get from the install .wim the file \source\bootmgrfw.efi (but then there are all the "localized" files or get it and all the other files from the installed system, usually C:\Windows\Boot\EFI\) and rename it to either bootia32.efi or bootx64.efi, BUT a normally installed windows will have that file as: \EFI\Microsoft\Boot\bootmgfw.efi then you will need to have (actually create) a (proper) BCD as \EFI\Microsoft\Boot\BCD, *like*: https://technet.microsoft.com/en-us/library/dn336950.aspx or: http://www.hasper.info/repair-a-destroyed-windows-7-uefi-boot-sector/ And then you will need to add the boot entry to the NVRAM. How? But that's where the BCDboot tool comes handy: https://technet.microsoft.com/en-us/library/dd744347(v=ws.10).aspx https://msdn.microsoft.com/en-us/library/hh824874.aspx jaclaz Link to comment Share on other sites More sharing options...
