I have an unusual problem while installing LUbuntu. I want to install it on my NAS (a QNAP TS-451). It has an internal USB pinheader where I connect a normal 128 GB USB-Stick. Fortunately the NAS has a HDMI output and plenty other USB connections so that I can connect a monitor and mouse/keyboard. The NAS as 1 GB RAM.
The BIOS is a bit limited but I can run Clonezilla to make backup and write them back…and I can run the LUbuntu live-DVD.
Therefore I tried to install LUbuntu on the NAS with the USB-Stick as bootdrive.
I selected minimal installation and connected to my WiFi, so that updates can happen during installation.
With respecto to partitioning, I seletected the GUID Partition Table and the following partitions:
- 400 MB, fat32, mountpaoint /boot/efi with boot Flag set
- 117819 MB (the rest) as ext2 and with mountpoint “/”
Installation works fine until the bootloader was to be installed. Then I get the installation failure:
"The bootloader could not be installed. The installation command
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader=id=ubuntu --force
returned error code 1
I have absolutely zero knowledge about UEFI and bootloaders. I already installed LUbunto on two ‘normal’ computers without any problems and they now serve as fileserver and its backup…but does anybody have an idea what went wrong and how I could install the bootloader to load in LUbuntu? Any help would be greatly appreciated
