Hi!
I have a Toshiba P50-A with Windows 8.1 self installed, and later with Ubuntu 13.10 overcoming all installation problems, both in UEFI mode. I have Secure Boot on, otherwise it wasn't able to enter the USB live session (buggy that it only boots that way), and have run boot-repair a couple of times without a satisfactory result.
If I just follow the recommended repair in boot-repair, I get a system that directly boots to Windows, after which by pressing reboot option & shift key and entering the Windows recovery menu, I can select boot from a different source and select Ubuntu system. After doing that, Windows shuts off, a Toshiba screen appears and it continues to grub, and later to Ubuntu, which works quite well. Here is the output URL from boot-repair with the recommended option:
http://paste.ubuntu.com/6641023/
If on boot-repair I select the option to backup & rename windows EFI files, I get a system that gives the following error when booting:
Checking Media Presence......
No media present.......
and after 5/10 seconds it decides to show grub menu, and both systems boot fine. The boot-repair URL entry after selecting this option is the following:
http://paste.ubuntu.com/6640942/
So in the first option I have to run through windows every time I want to boot Ubuntu, and in the second option, the system takes like 20s just to show the grub menu after showing a bunch of errors. I was hopping I can manage better boot options than this...
Any ideas, similar cases you know of??
What bothers me also, is the boot-repair summary message in the previous links:
Grub2 (v1.99-2.00) is installed in the MBR of /dev/sda and looks at sector 616448 of the same hard drive for core.img, but core.img can not be found at this location.
Boot sector info: According to the info in the boot sector, sda2 starts at sector 0. But according to the info from fdisk, sda2 starts at sector 616448.
Thank you for the help.
PD: I guess it is not important, but I have selected No Raid present when asked by boot-repair, and also the linux partitioning is based on LVM.
