Hi Vastone

I will not bug you any more about the lack of efi/gpt-support within VSIDO or the installer. Finally today while I was determant that this issue shouldn`t stop me from using VSIDO, I decided that I would install it permanently on a USB-Stick. So far so good. I created a MS-DOS system on the stick,with two partitions, I created one ext4-partition and a "dummy" swap-partition of the giant size of 30MB

Well, then in with the VSIDO-CD containing the latest ISO, hit tab to add "acpi_osi=Linux" and then hit enter. It booted just fine, and I started the installer. It detected the two partitions on my usb-stick, as I assumed it would, because they were ms-dos and NOT gpt... Well, I chose the swap-partition on the stick as it`s mandatory, and then the next step was to choose the root-partition and then I got a bright idea. I wouldn`t choose the root-partition that I prepared on the stick, instead I chose a empty ext4-partition on my gpt-disk, thinking that it was worth a shot. My thought was that the efi/gpt issue solely relyed on the installer, and that it would be sufficient to "fool" the installer, and that everything would work if I just could get it to install. Well, it proved to be correct... It installed just fine on my gpt-partition, and I also wrote grub to this partition...
Rebooted into Ubuntu that is my bootloader and master-grub, did a "sudo update-grub", and voila, it detected VSIDO in sda9 on my gpt-disk, and added an entry in efi..., as you see here:

So now I`m a happy camper, and you can be reassured that VSIDO handles efi and gpt just fine. It`s just a question of fooling the installer to think that you are about to install it on a ms-dos disk with a "dummy" swap-partition, and then all of a sudden, it detects the gpt-partitions so that you can choose those for root, home or whatever...
Well, now I`m logging of VSIDO and my PC for tonight, looking forward to many days configuring the appearance of VSIDO on my efi-booting gpt-disk. Problem solved. At least for me:)
