I used a live USB to install Ubuntu 14.04 and completely erase windows 8.1, the installation went fine but when I restarted the computer Ubuntu wouldn't boot from my HDD, instead it came up with try Ubuntu or install Ubuntu so I restarted without the live usb plugged in and I got an error message Reboot and select a proper boot device or insert boot media in selected boot device and press any key.
I read a lot of posts about people that had similar problems but so far none of the solutions that worked for them have worked for me.
I also ran boot-repair but that didn't fix the problem either.
Here is the link from boot-repair http://paste.ubuntu.com/7763898/
Please any help would be appreciated.
My laptop is a Toshiba Satellite U50D-A notebook with AMD A6-5200 processor
At the very top of boot repair info you posted it says you have two disks
/dev/sdahas an EFI boot partition and
/dev/sdbhas an MBR boot loader.
Check boot device
Boot your computer and go to BIOS by pressing one of:
And make sure you are booting from your hard disk.
Check EFI partition
According to Ubuntu UEFI documentation, the EFI System partition should have a 'boot' flag. According to the boot repair info you posted, your partition does not have it.
To fix: boot from Live USB and run gparted. From there you can edit your partition table and add the 'boot' flag.
