How do I change LL/Windows dual-boot (UEFI), to LL single boot (UEFI)?

[gold_finger]

Aside from deleting the Windows partition, did you change the size or position of any LL partition?

Did you change size or position of the EFI System Partition?

Just in case, go into UEFI Settings Menu and double-check to make sure that computer's boot mode is still set as UEFI and did not accidentally get changed to CSM/Legacy.


Assuming you still have the live Ubuntu dvd/usb you needed to install LL in UEFI mode, boot that in UEFI mode and post back output of the following commands from a terminal:

Code:

sudo parted --list
sudo blkid -c /dev/null
sudo efibootmgr -v

P.s.
Just to let you know ahead of time, I may not be able to check back here for another 10-15 hours.
