I am having problems installing Fedora 21/22-alpha on brand new system and I am new to the EFI thing so I am running into issues. I installed Win7, booted in UEFI, installed in UEFI, at least I see an EFI partition so that's a good indication it is in EFI. Boot security is disabled so I am guessing that's not the issue here.
I created a livecd usb with the following command:
livecd-iso-to-disk --format --reset-mbr --efi Fedora-Live-Workstation-x86_64-22_Alpha-3.iso /dev/sdb1
When I boot the system, I can select how to boot the liveusb so I select to boot it with UEFI. I see some lines that quickly scroll by then the system hangs at: "Use The" from what I guess is "use the arrow keys to make your selection" menu. The system is unresponsive at this point (power/reset button). If it matters, the motherboard is an ASRock x99 extreme 11.
I will add that if I boot in legacy mode (i.e. select the normal USB, not the UEFI: USB boot mode from the boot selector) I can boot the liveusb and install Fedora just fine, but I cannot get Windows to boot again. "Invalid Signature" error from Grub, no matter what I do (yes I did make sure to use the same
Does anyone have any ideas? I even tried repair-boot and that did not work. I am also under the impression that I need to boot the liveusb with UEFI to install fedora with UEFI. Thanks in advance.
