I purchased a new notebook, which has a pre-installed Windows 8 (upgraded to Windows 8.1).
- Secure Boot
- SSD + HDD
I downloaded Kubuntu 13.10, prepared a bootable USB stick and made some free disk space to setup a dual-boot system.
In order to boot from the USB stick I had to turn-off Secure Boot and switch to "CSM" ("Compatibility Support Module"; Legacy mode)!??
Now in the "Prepare partitions" (manual) step of the installer, /dev/sda (HDD) is pre-selected for "Device for boot loader installation".
As far I can see, the EFI partition is /dev/sdb1 (SSD; fat32) however.
but I always get an error about "reserved bios boot area".
Now as I understand, this "reserved bios boot area" is not needed for UEFI. So what should I do?
