Unable to boot Ubuntu Studio 18.04

[tedthetrumpet]

Had ubuntu studio working ok on dell laptop, but decided on a clean install of 18.04. Managed to install I think, but can't get it to boot. Tried boot-repair, which shows an error:

paste.ubuntu.com/p/4ZVGMyZGmr/

I installed this under a 'legacy' option rather and UEFI, as I can't seem to get the machine to boot from the usb disk under UEFI. Last time around I had similar problems, but did eventually get it booting under efi, not sure how.

When I try to boot I get 'no boot device found'. Booting from the usb drive, I can see in gparted that I have only one main partition, no boot partition at all. There are no other operating systems on the machine, and I don't need any.

Suggestions?

Thanks!

I can't see how to mark this as solved, but it is, sort of. More of a work around. I can't give a full account of the steps: tired and confused, been at it for hours! Broadly outline:

* booted from an install disk on an sd card rather than usb: not sure if that really made any difference
* used legacy boot to wipe disk and install system
* would not boot
* used gparted from install disk to add an EFI System Partition (ESP)
* reinstalled from legacy
* used advanced settings in boot-repair to change the grub location to the ESP
* finally now machine would boot UEFI into either the SD card, or, more importantly, the new system!
