Last year i purchased a Toshiba machine with Windows 8 preinstalled. After hard time, i managed to have dual boot on both OS. But accidentally, i updated Ubuntu and now i can not get the dual boot screen and the machine boots directly to Windows.
1) I tried the boot-repair and in the end i get "An error occurred during repair" , And i get the following report the report
It did not work
2) I tried also , on a command prompt as admin, to run the command "bcdedit /set {bootmgr} \EFI\ubuntu\grubx64.efi"
It did not work
Do you have any other suggestions?
Thank you in advance, Zampeta
