Newbie here. I unfortunately installed Hexxeh's Chromium OS on my HDD Vostro 1000 not realizing that it only works on SSD. Learning things the hard expensive way again! I want to overwrite it with Ubuntu but when I try to boot from the USB stick, the Vostro 1000 simply says the operating system is missing.
I don't understand why it matters if there is a pre-existing OS or not as Ubuntu (I think) just overwrites everything. Chromium OS replaced Windows Vista and now the HDD is GPT partitioned. Is there a way to get the boot to work?
