AFter following the steps that are presented here(Installing Ubuntu on a Pre-Installed UEFI Supported Windows 8 system), I could not boot the pc, even back to windows 8. I partitioned the Hard Drive, disabled the SecureBoot and the UEFI feature on the BioS and installed Ubuntu 12.04 LTS (x64) via USB boot. After the instalation, I restart the computer, and a black windows is showed, saying that error PXE-e61 is happening, and ask for a bootable device. I cant start windows or the ubuntu, and stay on that black screen forever. If i restart the computer and reactivate the UEFI/Secure Boot feature on the BioS, i cant boot back to windows 8, but cant start ubuntu.
Does anyone know that? Is there a solution? The computer is an Acer V5-171, with i3, 8 gb ram, 500 gb HD and Windows 8 Pre-installed.
