I am having the problem where I can't boot windows from the grub menu. I get the error: invalid efi path on startup when I select my windows boot. I have an ASUS UX31VD. Any suggestions as to how I can get around this? I suck with boot configs.

  • I didn't understand why you mentioned the absence of CD drive , if by that you mean , to boot the live Ubuntu Cd , or Windows 7 cd , please specify. Also you can boot to Ubuntu live through Usb. Drive

  • Type sudo update-grub from Ubuntu in Terminal window. and observe if it mentions windows 7 or not , report here.I guess you need to install grub in EFI partition.

  • yes it mentions windows, sorry about the weird cd-drive post, I mean to say I cant run windows repair or anything from a cd

  • Run Boot-Repair, update it, click Recommended Repair, write the final URL on a paper.
  • Reboot the computer.
  • In the GRUB menu, you should now see one (or several) new Windows EFI entry that allows to boot Windows. If not, indicate the URL.
