Public bug reported: My initial circumstance is that I was upgrading a perfectly-functioning dual booting (Windows 7 & Ubuntu 11.04) machine.
The 11.04 install that I did in 2011 went without a hitch and safely detected that I was UEFI and installed accordingly. When I tried to upgrade this installation, 12.04 - for some reason - decided that I shouldn't be able to boot both my Windows and my Ubuntu systems! Frustrated - but ever diligent - I reinstalled Windows 7 (in UEFI mode) and Ubuntu 12.04 fresh. Windows 7? No problem. Installed, was done as UEFI and I was off to the races there. Ubuntu 12.04? Forget it. It seemed to think that torching my GPT+UEFI boot partition would be a great idea and reinstalling it with some kind of MBR+GPT grub tool would be a better idea. Great. So now I have been forced to downgrade to MBR booting and I've completely lost access to my Windows 7 install. This is an enormous regression and if it can be solved is not even made slightly apparent through the Ubuntu 12.04 installation interface. Get your act together guys, my support for your project hangs by a thread at this point. I'm sick of the regressions and sloppy triage/testing/QA! ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001684 Title: UEFI Support Completely Broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1001684/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
