I started by using the USB install creator form my 12.10 installation, with the 12.10 image.
on my bios i disable safe boot, and enable legacy mode (or CSM a my bios calls it).
I reboot and press the key that the BIOS demands to select boot device.
in the list I have:
- P0: Windows boot manager
- UEFI: USB my_pen_drive_brand
- USB: my_pen_drive_brand
If I select "UEFI: usb" it will flash the screen, and go back to the same menu... if i select it again, it will flash the screen and boot windows.
If I select "USB" i boot into the legacy mode for the installer just fine and everything works. But i'm following the UEFI guide and since I want to dual boot with windows8, if I understood the guide correctly, i Must install in UEFI mode.
So, i can select this "USB" and get:
but the guide says i must select "UEFI: USB" and get this:
Or am I messing things up? Does the fact that windows8 can boot from P0 (when safeboot is enabled it shows "UEFI: P0" or something) means i can install ubuntu in legacy mode?
