I used the Gnome x64 Image. But I didn't try to use / with btrfs, that was just a note from a thred of another user in this forum that managed istallation with ext2 instead of btrfs. So I tried to use the older ext2 instead of ext4 for /boot
There are no files on my netbook that aren't secured on an external disk before I started the installation and, beware, there is no windows on the same harddisk
My laptop is with UEFI.
The Sabayon Installer suggests me to format the Disk like this:
/boot/efi (as EFI)
-> / (ext4)
-> /home (ext4)
Using this, grub tells me "Unknown Filesystem"
Then I tried this (without LVM)
And my laptop quits with "Operating System not found"
There is never a grub window shown, version 1 starts direct into a grub shell.
It seems, that the EFI installation of sabayon is not recognized by my laptop.
On the first try I had an old entry "ubuntu" from the previous ubuntu installation in my boot device list. This option ended up in "Unknown Filesystem"
But Sabayon is not recognized. So, since "ubuntu" is removed from boot device list I cannot get more than "Operating system not found"
I tried to reinstall Sabayon with default parameters and tried the Bootloader recovery option. Didn't work.
