I am using old computer standard phoenix BIOS, it does not have UEFI. I was installed Windows 8 first, then Ubuntu. When grub installed, I can't access Windows 8 anymore.
update-grub can't find my windows, bootrepair can't repair. After tried grub-customizer. Grub customizer can find windows partition and added entry grub config. But windows 8 can't boot. Grub menu gives this screen:
Also I tried fixmbr and rebuildbcd, they do not solve the problem.
