For the gnome version ensure that the settings for the guest operating system "Other 64-bit" are. Also provide at least 512 memory but abit more is better.
Normally it should work now. But if you keep having difficulties with the installer you can always use VirtualBox instead the gnome version installs on VB without any difficulties.
And now the problem child KDE 64-bit.
ensure that the settings for the guest operating system are "Other 64-bit".
I took 776 memory, (I had been trying for to long to keep a little bit of extra memory to be sure stand in my way)
For the processors change virtualization engine from 'Automatic' to 'Intel VT-x or AMD-V' and put 'Disable acceleration for binary translation' on. After the installation you can put both back on default.
Normally it should work now. Don't forget to apply the startx-fix (I had to remove only the 2 files in cache-root before install and after I had remove the once in cache-bt also)
For the installation in Virtualbox I used 'Other Linux' as operating system.
At the System menu:
- on the Motherboard tab put 'Enable IO APIC' on and make sure you got at least 512 Memory (think default is 320 or so)
- on the Processor tab put 'Enable PAE/NX' on
- and on the Acceleration tab make sure both options are on
These settings worked fine for me, now only have to find out how to install the guest-additions. Keep get an error because the installer can't find the sources of my current Linux kernel.
Hope some of you can finaly enjoy BT-5 KDE 64
Found the how-to on how to prepare kernel sources so guest-additions work now
