Installing Ubuntu on a Pre-Installed UEFI Supported Windows 8 system
I got a new DELL XPS 8500 with Windows 8. I understand that it has UEFI (as opposed to traditional boot-loading BIOS system).
I installed Ubuntu 12.04 (not realizing that it doesn't work as well with the secure-load/uefi system). I partitioned my solid state drive so Windows was on one partition, and Ubuntu would be on a new one (sdb7). This always worked with my PREVIOUS computer... I had Windows XP on one partition and UbuntuStudio on a separate partition. Grub always gave me a boot menu.
Here comes the problem:
At first my computer wouldn't let me boot from the USB and with UEFI I can't get into the boot menu... with UEFI I have to access boot options via Windows. I had to un-select "secure" booting, which allowed the computer to boot from my Ubuntu USB.
I successfully installed Ubuntu, but when I restarted the computer it booted right into the USB again. I expected it to give me a boot menu (including Windows 8, Ubuntu, and the USB stick).
So I shut down the computer, removed the USB stick and restarted it... and I got the following error message on a black screen:
"Reboot and select proper boot drive or insert boot media in selected boot device and press a key."
NOW this SHOULDN'T be a huge problem... I should just "select the proper boot drive"... but I can't access BIOS or a boot menu unless I'm inside Windows!! And I can't get into Windows!
What I can do (ALL I can do) is run Ubuntu live from my USB. I've looked at lots of forums and I've tried several things, but nothing works! This is kind of a new issue so maybe nobody has had this problem yet. Others had the same error message, but from different problems. They can usually ONLY log into Windows. I can't get into Windows.
When I boot Ubuntu live from the USB I can look into the files for my Windows and Ubuntu installations, but I can't boot into either one.
Here's what I tried (which didn't work so far):
-re-installing ubuntu 12.10 -boot-repair program in Linux
Here's another piece of information. When I tried boot-repair, it told me that "The boot of your PC is in Legacy Mode... You may want to retry after changing it to EFI mode."
I don't know how to change it to EFI mode.
ALSO... boot-repair tells me to: "remember to tell the bios to boot on sdb1/EFI/ubuntu/grubfix64.efi"
I don't even know what that means.
If you're interested... I tried the boot-repair three times and got these URLs:
Anyone with any info PLEASE help me out. My brand-new computer is unbootable...
