Downloaded and burned ubuntu-14.04.1-desktop-amd64.iso. Checked md5 of iso and md5 of burned DVD.
Installed 14.04.1 LTS on a new Toshiba Satellite laptop. Replaced the existing Windows 8 install. The installation worked fine, but when I restarted it will not boot:
Reboot and select proper Boot device or Insert Boot Media in selected Boot device and press a key
Turned off Secure Boot. Tried turning off UEFI Boot (CSM), but only got a blank screen with a flashing cursor, and Boot Repair did not work unless in UEFI mode.
Set the boot order to first hard drive, then DVD-ROM.
Ran Boot Repair several times, and changed the partitions around. Tried to create EFI partition, but Boot Repair kept complaining it was missing.
Finally deleted all partitions and reinstalled OS for 2nd time. Same symptom.
Changed the partitions to create bios_grub:
sda1 unknown 2 MB bios_grub sda4 fat32 510 MB boot sda2 ext4 461 GB ---- sda3 swap 3 GB ----
Used Boot Repair: Boot Repair pastebin
Followed several guides, but they all seem to show how to do a dual boot. This computer is not dual boot. Only Ubuntu.
- How does the BIOS (UEFI) know which partition to boot? There are no options in the Toshiba BIOS startup utility.
- Why doesn't it boot? How to fix?
