I have an HP a1640n desktop which is a pretty standard Vista Home Premium machine. I bought a Maxtor OneTouch Plus drive to back it up. Seagate/Maxter software boot CD would never work. Linux based (I think) and we tried all the same commands listed on this forum (acpi=off noapic). Seagate then offered to me their Seagate DiskWizard which is a dumbed down version of Acronis True Image(?). This worked fine and I can boot from the CD if I need to for recovery. I decided I like it so I bought the full version of True Image 11 and what do you know....I can't boot from the CD for recovery. Explanations and/or suggestions as to why and how can I get to work?
