The downside to setting legacy is that Windows cannot be loaded from the grub menu. The upside is that the little nuvo button next to the main power button on the Z580 makes it easy to get into the bios without having to hit DEL or F2 or something before a timeout. So to switch back to booting Windows, just powerdown and power up with the little nuvo button. A menu will allow you to enter the BIOS to turn UEFI back on.
Caveat - I installed Ubuntu with UEFI off and legacy enabled. Things may behave different if Ubuntu was installed with UEFI on. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1093217 Title: Ubuntu 12.04/12.10/13.04 10-20min boot delay (From 3.2.0.29->3.8.0.19) [Lenovo IdeaPad Z580] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1093217/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
