    Re: dual-boot Windows 8 and Ubuntu 13.04

    I must not have clearly communicated my issue. I cannot boot into Windows at all, I did as you suggested above, now I can't boot at all, don't get the GRUB menu. http://paste.ubuntu.com/6008063. What happens now is I go straight to the "Preparing Automatic Repair" screen, which never does anything, just sits there displaying that message. Can I un-do what I just did by un-checking the "restore EFI backups" option in boot-repair?

    UEFI controls booting choices. I cannot tell from Boot-Repair which choice in UEFI you are using. If booting the Windows entry in UEFI mode then Windows needs repairs from a Windows repairCD or flash drive if you cannot get it to run its own repairs.

    If you do not have settings correct in UEFI, such as trying to boot Windows in CSM mode then it would be expected that it would fail.

    You can restore the Windows boot file with the undo command, but it seems like you already are booting Windows? I would try the undo.

    That was just the PBR - partition boot sector. NTFS PBR has different configurations for each version of Windows to know what to boot, but it is not showing any boot files. All NTFS partitions have to have the boot signature even if data. But not used unless booting.

    All of sdb is MBR(msdos) partitioned, so nothing will boot from a UEFI boot. The old Ubuntu install may boot if UEFI changed to BIOS mode and the old install has its boot in the MBR, but syslinux is in MBR now.
