Ubuntu server 12.04 need disk (UEFI)?

Question

ubuntu

I'm trying to install ubuntu server 12.04 on a computer with a UEFI mother.
When installing from a USB flash drive, when copying data, I get the error "No cd disk found ...". On a virtual machine, the 13th version of Ubuntu does not have such problems. There is an opinion that the problem is in the mother's UEFI. This error occurs during normal booting of a flash drive and when booting in UEFI mode. Safety is Othe OS.
In Google, the question "Ubuntu disk not found" and similar results are displayed that do not quite satisfy me. Basically, people have a problem with the disk requirement when updating.

Answer 1

I found the solution by installing via Online installation. mini distributor. Unfortunately, I did not teach the full-fledged image itself to read from a USB flash drive in UEFI mode.

Answer 2

I suffered for a long time, but I could not put ubuntu in efi mode from a flash drive. I had to look for a drive.
