DualBoot Win8/ubuntu 13.04

[ayman2]

Hello,
I have a new vaio with Windows 8 preinstalled, and I've installed ubuntu 13.04 with it (first I had problem booting but after a boot-repair, and desabling sucure boot on the bios. Everything worked well)
But the problem now, is I can't update Windows. In the process of the update after rebooting (and chosing Windows on grub) Windows runs normaly (the update doesn't continue) and it asks me to do the update again.
Anyone have a solution to this problem?
Thanks.

Rather than boot Windows from grub, can you not boot it directly from UEFI.
Or did you run the rename function that creates the bkpbootmgfw.efi and the Windows original file was bootmgrfw.efi.

I didn't know that I should run the bkpbootmgfw.efi, thanks it's working now =)
