I find it quite queer and odd that I'm stuck and stumbling over a new dual boot install. I've done too many installs to keep track of the number and I'm wondering if I had taken something for granted: The fact that you're always asked on which partition or drive you'd want to place the boot loader. For once, the installer doesn't ask so I assumed putting the flag boot/efi to the efi partition would suffice. Alas, nope. When the install finishes and I reboot, Windows loads. I have to manually press the boot key to get a boot menu but I'm thrown to a grub prompt afterwards. Could it be the option was removed or my iso download got corrupted somehow? The checksum says it's fine so I'm thrown a loop. Of course, there a few things that I didn't say like choosing manually partitioning as that's the ONLY option that allows for encryption. Any help would be appreciated.

Thanks Claydoh, but I had manually shrunk the partition before that using 3rd party tools under windows. I only had the efi partition (which I had enlarged after Windows set up). Windows recovery partition, the Windows installation and the freed space.Originally posted by claydoh View Post
I'm guessing I'd have to re-extend the partition if that's the case. I'm guessing that's a safer way around it.Attached FilesLast edited by Princey; Yesterday, 09:30 PM.Challenges are what that keeps us from the borderline of boredom in life's journey.

So, did you set the boot flag in the installer?

I did, but it didn't work. Tried it again, no result. Had to end up extending the partition that I shrank, reboot, then let the installer shrink the partition by itself. Found out after that with the installer handling everything, a new 4GB partition was created by the installer labelled kubuntu_2510 and flag set to boot only. Previously, I had the efi partition set to boot/efi and boot. Not sure if that was the issue. Will take some time and learn more about flags and partitioning later on.Originally posted by claydoh View PostChallenges are what that keeps us from the borderline of boredom in life's journey.

Do you know about efibootmgr? Running it from the live USB should show where each boot entry goes. Unfortunately the output is not easy to understand, at least I find it so.
Getting a grub prompt like that suggests that UEFI has found EFI/ubuntu/grubx64.efi somewhere, but that the grub.cfg there points to somewhere without /boot/grub, or somewhere that doesn't exist.
Is secure boot enabled? I wonder if you're trying to do an install that secure boot doesn't like.Regards, John LittleComment
