I installed Ubuntu 14.04, Windows 7 and Windows 8.1 in the same computer. Whenever I boot my computer, there is the boot options (1):


Ubuntu
Ubuntu configuration
Ubuntu memtest
Windows 8

When I choose Windows 8, it will reboot to Windows boot options (2):


Windows 7
Windows 8.1

If I choose Windows 7, it will boot directly to Windows 7 and vice versa. But after a few crash recently, I can't boot into Windows option, whenever I chose the Windows 8 options in (1), it would reboot back to (1), it didn't open the Windows option like (2). I tried to use a bootable usb to restore the Windows to early system restore but after restarted, the problem still didn't solve.
I used Boot Repair in Ubuntu to fix but it didn't work either. Here is the log (http://pastebin.com/raw.php?i=AuJ29hWt)

I am quite new with Ubuntu so I really appreciate any help.

Boot-Repair is primarily for Linux boot issues. It can only make minor repairs to Windows.
Grub only boots working Windows.

So you need a current version Windows repair flash drive for every version of Windows you have installed. And as I do in Linux I also have several other repair tools as live bootable systems.

Windows 7 repair USB, Also Vista if service pack installed

Windows 8 UEFI repair USB must be FAT32, not for reinstall, just repairs

Have you installed everything in BIOS or UEFI boot mode.
Windows often needs chkdsk, which you can only run from Windows. Or BCD repairs, since your BCD has both Windows entries.
Since Windows issues, you may want to restore Windows as default boot. You can do that restore with Boot-Repair or your Windows repair or install flash drive or DVD.

Then once Windows is fixed use Boot-Repair to restore grub2's boot loader.

If UEFI, you directly boot from UEFI boot menu.

Thank a lot for your answer! I will try to select boot from Windows as default options. I already made a Windows 7 repair with my usb drive, should I need another 1 for Windows 8?

I am not sure but I thought it may be BIOS mode

Windows often needs chkdsk, which you can only run from Windows. Or BCD repairs, since your BCD has both Windows entries. I don't know what BCD stand for, please explain!

Already set, I will reboot right now!

Windows BCD - Boot Configuration Data
That replaced XP's boot.ini which was plain text. The BCD is some sort of hive and requires Windows tools to edit.

BCDboot Command-Line Options Windows Vista/7/8 recreates boot files.

I had a Windows 7 repairCD/flash that I used on my XP for running chkdsk.So I would think you may be able to use Windows 7, but do not really know. Often better to have newer version as repair tool, as it may have updates and do a better job.
