the problem affects Ubuntu 14.10 Daily build of 9 october. not 10 september

[Axel (naxel)]

Still reproducible with VirtualBox 4.3.18.

For other people running into the same issue: adding the kernel bool param vga=791 helps start up the live image; the installed kernel does not need any extra boot param.

Status changed to 'Confirmed' because the bug affects multiple users.

In Spain / Latin America
Press F2 to change the language
f3 to change keyboard settings
F6 / intro to select Expert Mode . ESC and add vga = 791 . Then press enter

Ok, so managed to get it to boot into the installer after like 5-6 reboots. Seemed totally random. Installed and booted into LightDM at first try.

Vbox 4.3.16 on Win 7 host. Guest 14.10 AMD64 have the issue. The F6 and vga=791 solution works for me.

Install latest virtuabox 4.3.18

This bug still exist in ISO (x64) from 23 october. Tested on latest virtualbox.

Also vga=791 work fine.

[ATIpro (somebody2112)]

Same problem booting Lubuntu 14.10 AMD64 in Lubuntu 14.04 AMD64 (Virtualbox 4.3.10). It can be fixed with vga=791 kernel parameter.
