Manufacturer: Dell Inc.
Product Name: Latitude E6410
Instead of upgrading, I tried to install new Xubuntu 16.04 in UEFI mode.
Switched BIOS boot from Legacy to UEFI and disabled the RAID for SATA.
(SoftRAID/FakeRAID corrupt the GPT table backup in the end of disk, on each boot)
Booted using USB key in UEFI mode & resized and converted partition table from MBR to GPT.
- Booted again using USB key in UEFI mode and installed Xubuntu. Created a new boot EFI (FAT32) partition.
On reboot, There is a Ubuntu entry in UEFI menu but selecting it raise a BIOS error message about no boot media.
Tried multiple things but no success:
- Boot-repair.
- Change EFI partition to FAT16.
- Reinstalled Xubuntu.
