Unable to boot into Windows after installing Ubuntu, how to fix?
18 answers
I have a MacBook pro and have downloaded bootcamp Windows 7, and was trying to dual boot Ubuntu. I got it to download and start and went into the installation setup and it asked me to do something with the partitions and I was messing around and accidentally marked the Windows folder as biosgrub.
It then froze and I forced it to shutdown, but when it rebooted, it said missing operating system and I can't boot Windows anymore. I can get into system recovery and can still see the files, but it just won't boot. I could restore OS X and buy another Windows disk, but I was wondering if there was another way.
dual-boot

Was it just the bios_grub flag? or reformat as bios_grub is totally unformatted space. And if grub installed its core.img into it, it would have erased part of Windows. If not you may be able to remove bios_grub flag, make sure partition is NTFS.

You should be able to solve an issue like this with Boot-Repair. It will scan for "lost" operating systems and add them to GRUB.
I can't get into a terminal besides the Apple recovery terminal. As soon as it boots, it said missing operating system and I have to force shutdown before I can do anything else.

Please see the instructions I linked on Boot-Repair. Both options involve booting into a live environment. You will need to prepare a USB (or optical disc) with the utility preinstalled with boot-repair Or you can follow the second option to do it manually within a live Ubuntu USB or disc.
