I was trying to install windows on my MacBook and things weren't working during the windows side of the install. After restarting and going to the utility screen by pressing cmd + R, I tried to do a time machine restore, it isn't finding my Mac HD when it asks where I want to restore to. Also in disk utility it says "virtual whole disk" where Macintosh HD usually is. Lastly, when I restart holding option to get the boot menu, the Mac boot option comes up but nothing happens. I stay on a gray screen with a "no solution" logo in the middle. Any advice would be very helpful.
