I have an hp pavillion g6 with amd-3400m apu. I recently had to do another recovery of my windows side and reinstall everything. this has happened once before. But this time when i try to reinstall ubuntu 12.04 or 12.10 as a program within windows, it will eject the cd and tell me to remove media and reboot after clicking install inside windows. when it reboots windows just starts up normally.
I installed both cds before with no problems, (and they were both the 64bit amd versions), the md5 checksums are also fine like they were before.
I would try a later version on cd but i have no more left to burn and i can never seem to get a usb installation to work at all either.
