This is basically the same as another question (I would link but your karma checks don't allow), but the suggested answer there didn't work for me and I don't have the points to comment there.

My machine: HP 7t/7000 laptop (2012 vintage), with two drives -- sda is my windows disk, and sdb is my linux disk. The Windows disk runs Windows 7.

I tried installing Fedora 20. It promised not to mess with my primary (Windows) drive, but it didn't mention that it would install UEFI menus that only point to Fedora. Not cool. I don't belief I was using UEFI before, although the BIOS supports it. Anyhow, now I'm stuck with Fedora UEFI menus, and of course, uninstalling didn't help.

Booting from the Fedora install disk does NOT allow removing entries via efibootmgr:

[root@localhost liveuser]# efibootmgr -v
Fatal: Couldn't open either sysfs or procfs directories for accessing EFI variables.
Try 'modprobe efivars' as root.
[root@localhost liveuser]# modprobe efivars
[root@localhost liveuser]# efibootmgr -v
Fatal: Couldn't open either sysfs or procfs directories for accessing EFI variables.
Try 'modprobe efivars' as root.
[root@localhost liveuser]#

The HP Bios is pretty crappy and also does not support manipulating the UEFI options.

I don't understand the problem here. Did you expect something other than the Fedora installer creating Fedora boot entries?

I had a laptop that booted Windows (using legacy mode). I didn't expect to end up with a laptop that wouldn't boot Windows without pressing PF-keys to interrupt the bootup process and invoke non-EFI options.

For the record, I figured out that deleting the UEFI partition on the second disk was enough to get the System to mostly go back to normal. There's still an additional entry pointing to Windows somehow, but it isn't causing any harm.

Just my opinion, but I think the Fedora installer would be better if it did more to make clear the changes it intends to make.
