I just installed Ubuntu alongside window 7 by following the instructions on the internet . I can use Ubuntu successfully. But I failed to boot Window 7.
I got this error: invalid EFI file path.
I was looking at other similar posts. They mentioned something like ""Window UEFI", which I have no idea what is means.
Please can someone tell me how to boot Window 7 again without losing everything on Win 7.
UPDATE: I reboot my laptop again. I pressed F2 / F10 to launch boot manager. I changed the boot option: boot option #1: Window blablabla boot option #2: Ubuntu blablabla boot option #3: Ubuntu blablabla
Then Suddenly I was able to launch Win 7 again. The weird thing was that it ran a disk scan / file scan after I logged onto my Win7 account. And I was prompted to format the local disk (:E) , which was where i installed my Ubuntu.
I am very puzzled now. Why cant I launch Win 7 in GRUB, but I can do so after rearranging the Win 7 boot option. Should I really consider removing Ubuntu, since I am worried I am going to lose my Win 7 again ?
