I have to add the following to the boot command when installing :- nomodeset ati.modeset=0 radeon.modeset=0 and then I can get to the desktop with a complete install. Once there, I then have to install a proprietary driver.
Thanks for that, I'll make a note for future reference. However, from the research I've done ATI's current proprietary driver releases do not support my (apparently ancient) card, so I've rolled back to 12.04 which is working fine except for giving me the "signal out of range" error during boot. I can live with that, at least for now.
Sometimes it turns out that installing Linux can be as hard work as installing Windows!
(And... why is there no VESA standard above 800x600? Minimal 1024x768 and 1280x1024 VESA compatibility across all graphics cards would go a long way to making this problem go away!)

When I had some boot issues, I was pointed at https://help.ubuntu.com/community/BootOptions
There is a boot option vga=xxx
I then followed the link about vesa modes to the standards you want :-)
http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers
I then followed the advice there, and did
sudo hwinfo --framebuffer
I then picked the resolution listed there, and used it in the boot option
e.g. vga=0x0318 for 1024x768 24 bits.
That may help. If not, ISTR there's an XORG utility that will detect your preferred screen resolution and write it to your xorg.conf file - this may or may not help with the signal out of range option when booting.
There's also a program called XRandR (or perhaps just RandR) which helps set the screen resolution once booted, though I don't know if it'll have any effect during boot.
Good luck!
