I've tried to install Ubuntu on a VMWare Virtual Machine, but it never gets past the bootloader :

ISOLINUX 4.01 debian-20100714 ETCD Copyright (C) 1994-2010 H. Peter Anvin et al
No DEFAULT or UI configuration directive found!
boot: _

I've also tried to burn this .iso image to a CD and go from therem but I got the same problem.

Some more details :

  • VMWare Server 2.0.2 Build 203138 on Windows 2008 R2
  • ubuntu-10.10-desktop-i386.iso image used (downloaded yesterday evening)

If you are able to use a USB stick as installation media, then rename the following:

  • isolinux --> syslinux (this is a folder)
  • isolinux.bin --> syslinux.bin
  • isolinux.cfg --> syslinux.cfg

This worked for me.

Two suggestions:

Suggestion 1:

If you are using a USB stick, make sure it is formatted as FAT16 (or just FAT), not as FAT32.

Suggestion 2:

Try entering mboot.c32 -c boot.cfg at the "boot:" prompt.

If you're using YUMI with USB memory stick there are certain Ubuntu versions which ISOs are not added correctly - for example, 16.04.5 LTS versions is added OK but version 16.04.6 LTS ISO image results in the "No DEFAULT or UI configuration directive found!" error

I wrote the Ubuntu image to a USB flash drive using Startup Disk Creator and had the same error during booting it.

Launching Partition Manager I saw that the partition is FAT32. I recalled that I didn't format the partition during image writing -- it already was FAT32 (perhaps from previous Windows installation).

So I deleted the partition using Parition Manager and rewrote the image (Parition Manager showed that the created partition is FAT32 too). It booted fine. I guess something was wrong with the format of the partition.
