Problem with Dual Boot to Windows 8

madsravn · 2016-12-08 17:56:48

I have been having problems getting my Windows 8 to boot for some time now.

I have the following setup:

[root@Adria mads]# fdisk -l
Disk /dev/sdb: 111,8 GiB, 120034123776 bytes, 234441648 sectors
Units: sectors of 1 * 512 = 512 bytes

Disklabel type: gpt
Disk identifier: EFD815CE-A8E1-4F65-8949-6453DAADBD8F

/dev/sda1 2048 616447 614400 300M Windows recovery environment

/dev/sda4 1081344 488397134 487315791 232,4G Linux filesystem

/dev/sda4 is my root. /dev/sdb2 is the Windows partition and /boot is on /dev/sda2. It's uefi.

I cannot for the life of me get Windows to boot. bootctl tells me this:

[root@Adria mads]# bootctl

Could anyone direct me what to do? I have tried using grub and refind, but nothing is working. It also seems like I cannot boot Windows from my BIOS using the "Windows boot loader". Would that indicate that it is my windows that is something wrong with instead of it being something I can fix from Linux? When I mount /dev/sdb2 it looks decent - like a normal Windows installation.

Do you require additional information to tell me what I am doing wrong or to suggest a fix?

I hope you can help.

The Windows bootloader is present on the ESP, you can use this to generate an NVRAM entry for it:

# efibootmgr -c -d /dev/sda -p 2 -L "Windows" -l /EFI/Microsoft/Boot/bootmgfw.efi

However, I think that perhaps the bootloader is corrupted or damaged, have you tried a Windows recovery disk?

Also, please use code tags rather than quote tags for command output and configuration files.
