Hi,
I recently installed Ubuntu on my Toshiba Satellite laptop which preloaded with Windows 8, everything was working fine until the wireless chip was temperamental in Ubuntu so I installed Opensuse instead and removed Ubuntu in the process, I have turned Secure Boot off in the BIOS menu.
However after Opensuse installation the boot menu was somehow messed up and it went straight into grub command window after starting the laptop, hence I am not able to boot into either system, anyone who can recommend a solution will be much appreciated in advance.
Note that when the laptop is starting up, on the top left corner it shows:
Failed to open \EFI\Microsoft\Boot\grubx64.efi - 80000000000000E
Failed to load grub
Failed to open \EFI\BOOT\grubx64.efi - 80000000000000E
Failed to load grub
I noted these lines popped up after installation of Ubuntu but at least it went straight to grub menu where I could pick whether Ubuntu or Windows 8 to boot into, so I am not sure if there are multiple problems that need to solved here?
This is “file not found”. Sounds like you formatted you EFI System Partition during installation. Please boot from rescue DVD in EFI mode and paste output of “efibootmgr -v” and “gdisk -l /dev/sda” (I assume you have single disk; if you boot from USB it may be sdb instead).
I messed the EFI up further as I was trying to fix the EFI through HDD recovery upon restarting the laptop, now the laptop has not idea where to boot from so it says “Reboot and select proper boot device or Insert Boot Media in selected Boot device and press a key”. I then restarted the laptop with Opensuse on a USB stick but it went straight to the grub command instead.
What do I go from here? The only live Linux distro I have on hand at the moment is Ubuntu, I did not make a recovery media in Windows 8 so if I could fix the EFI and be able to go back to Windows 8 would be ideal.
If EFI then you should have an EFI boot menu. Trouble is each manufacturer seems to use their own special key at boot to get to it. F10 and F12 are common but by no means the only one. Often the computers boot screen may show options though they tend to go by rather fast. If you did manage to wipe out the efi boot partition then you must rebuild it. There is a openSUSE repair ISO image or you can use any of the live ones. You can not use Ubuntu or Windows to fix openSUSE. At least I don’t know a way since each OS does things a bit different.
If it is a live version of openSUSE on the USB then you can use that to repair. If the full installer then I think there may be a repair option but that leads to command lines.Someone would need to walk you trough that.
If you have the full install ISO then you can reinstall using the upgrade option. This will bring all back to square one but keep any programs you installed and preserve home etc. Yes upgrade from 13.2 to 13.2. You will have to reinstall most updates.
It does not matter as long as you can boot it in EFI mode and it has efibootmgr command.
If you have to fix the EFI boot stuff do not use a foreign OS. But you could use ubuntu to look and maybe repair the EFI flash but you can not repair the EFI partition’s boot entries
