I recently had to re-install Ubuntu because it would not boot after some software changes. To install from a Live USB I had to change from UEFI mode to CSM. After reinstalling, the Grub menu does not show up and nothing boots unless I am in CSM mode and when it does, there is no Windows boot manager as an option and there are two new options called memtest86.
I ran the
boot-repair tool in Ubuntu but nothing changed. When I boot the "Windows recovery" option in Grub it says that something went wrong with Windows and to load my Windows Recovery CD which I do not have.
From what I understand, I might have overwritten the Windows MBR in which case, since I don't have a CD I need to use
lilo in Ubuntu to get it working again?
I have looked at all the questions here on this subject and that was my conclusion but I do not want to try it until some one could confirm. Thank you in advance.
