Windows 8 Dual Boot on standard bios (Without UEFI)

rated 0 times [ 0] [ 0] / answers: 1 / hits: 2062 / 2 Years ago, sat, december 11, 2021, 5:16:35

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.

My bootinfo at http://paste.ubuntu.com/5565925/

Thanks!

I solved my problem with clean install. I think problem was hdd slot change.
When I was installing Windows -Talking about my bootinfo- sda is sdb and sdb is sda.
Then I changed hdd slots and install Ubuntu on new sda was before sdb.
I guess, this change confused grub and can't find Windows 8.
