I bought a new HP PC (details below) intending to replace W8.1 with Ubuntu. Boot failed with both 12.04 LTS and 14.04LTS. The details below are pretty much the same for both.
The system gets as far as rebooting into 14.04 after installation from .iso image on USB disk. I am running grub 2.02~beta 2.9. Ubuntu is supposed to install successfully.
When you start up (without USB disk present), it offers a grey screen with a purple border 10-20px wide all the way round. It then puts up a tty screen with the login, then after a while comes up with:
"Your screen graphics and input device settings could not be detected correctly. You will need to configure them yourself."
It then says "what would you like to do?" and offers a menu list the first of which is:
"* Run in low graphics mode for just one session."
There are a list of other options, but these are greyed out.
Hit .... System freezes (no movement after 15 mins or so.
Looks like grub/Ubuntu can't recognise any I/O devices. It should be happy with the Radeon graphics shouldn't it. I believe that the touchpad is standard too.
How can I sort this??
BTW before anyone suggests h/w failure it runs W8.1 just fine :-( - if you like that sort of thing.
It bombed on Mint16, too.
HP Pavilion Notebook AMD A10-5745MAPU + Radeon Graphics + 8GB + 1TB disk Bios is Insyde F.13 (Insyde H20 setup utility R3.7)
I have got UEFI running because 14.04 is supposed to be able to handle it. Legacy boot is disabled.
The grub partition is at about 1 MB, the main partition is about 800 GB and the swap is about 17.8GB
