I have a HP Envy 15 j069sf, on which I must dual boot windows 8(.1) and Ubuntu >12.04.

It came with Windows 8.1 pre-installed, I used GParted to erase all the disk and install Windows 8.1 myself on 1/3 of the disk.

Then I heard Ubuntu don t goes well with UEFI, so I used GParted anew to erase all disk, and installed Windows 8 in Legacy mode (not booted from EFI file, Legacy mode activated in BIOS).

Then I goes to Ubuntu download, I took 12.04 because it is LTS, and even if my computer is x64, ubuntu.com redirect me on 32bit i386 version automatically.

Since I know I m not on a AMD64, I thought it was for compatibility, and I don t care the few 64bit advantage I lost by installing in 32bit, so I downloaded it.

When booting Ubuntu from efi file, it start to load then freeze, and when I boot it directly the disk is shown empty, even if I have two NTFS patition on 2/3 of the disk!

So my question is:

Why do the disk is shown empty in the ubuntu installer (750GB free, it s the size of the hard disk).


I can reinstall Windows if needed, I have access to Windows 7, 8, 8.1 in Pro version.

I am trying to download the latest Ubuntu right now, see if it change anything. Strangely, it take me on the amd64 download...


Ubuntu 13.10 AMD64 don t detect my partitions either, trying with 12.04LTS AMD64
