When I boot my laptop (Dell vostro-3450) 9 times out of 10 I get the message from BIOS "Operation system not found" and I have to power cycle again. Eventually Ubuntu will load.
I've checked in BIOS and there are no relevant options to configure, its very basic.
I have installed and run boot-repair but the problem remains. here is the output from the boot repair:
The drive (an SSD) is just one big primary partition, and I notice at the end of the report there is this message:
"The boot files of [The OS now in use - Ubuntu 18.04.3 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. ()"
Which seems like it might be the problem, but I don't think its possible to create a new partition at the beginning of the drive without destroying the existing partition.
Is there any way I can fix this without basically reinstalling ubuntu?
Edit:
Output of sudo lshw -c disk

I managed to update the BIOS to the latest version, A13 from A05, and this seems to have resolved the boot up issue. I had to create a 32bit windows 7 USB stick to get the bios update utility to work.

sudo unlink /dev/disk/by-id/wwn-0x5002538d400f800d-part1 and
sudo unlink /dev/disk/by-id/wwn-0x5002538d400f800dupdate your the initrid from current running kernel
