Yesterday your advice got my machine up and running. So this morning, since last night I had to reinstall Vista to get out of a boot loop, I’m thinking I should look at the BIOS and make sure I’m booting to the HD and not the windows cd. It’s a Gigabyte P35 DQ6. BIOS had reset itself to boot first to the HD. That was interesting. Next I highlight “load optimized defaults,”changed No to Yes and pressed F10 to save and exit. But pressing F10 nothing happens. Make your change exit and save. What am I doing wrong? Thanks as always.
