I am trying to perform a new install of Ubuntu-Desktop (ubuntu-13.10-desktop-i386.iso) using a USB. The machine boots into the USB however it starts alternating between a blank screen and a purple screen with the mouse cursor in the middle of the screen and eventually gives me the message/error below. When I hold down the shift key while its booting into the USB stick I get the menu with the options Try Ubuntu without installing, Install Ubuntu, Check disc for defects, Test Memory, Boot from first Hard disk. The only two options that perform the function it should are Check disc for defects and Test Memory. All other options alternate between a blank screen and purple screen and eventually the below message/error.
I have read many pages on the below message/error but all seem to be related to a machine that is either been upgraded from another version with the OS on the HDD therefore enabling them to perform many of the given fixes. I don't have any OS on the system and am trying to install for the first time. This machine used to have Windows XP but that no longer works missing system files therefore I am trying to install ubuntu 13.10. I have also tried installing using a DVD and that does the same.
I have downloaded a new copy of Ubuntu tested the checksum, tested the disk integrity all 100%. In the install menu I receive after pressing shift, I select nomodeset and have also tried to enter in the bottom line of text vga=771 but still nothing same as before.
MESSAGE/ERROR: The system is running in low-graphics mode Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself. After clicking OK I receive another menu but any option I choose there I get a grey screen and then nothing.
I am installing on a Desktop PC System: Mecer Xtreme Pentium 4 3015MHz, 500MB DDR RAM
Remember I have no working OS on the machine therefore I am not sure what to do, please assist.
