I was trying to install Debian on my new laptop: a Lenovo Y50 64bit running Windows 8. I got together with a friend and installed Debian in his computer first and had no problems. However I've tried to install Debian several times using the AMD64 KDE and netinst versions and accomplished nothing.
I am trying to dual boot with windows 8.
To install I disabled secure booting.
First try: installed the KDE version. Grub would let me choose which operating system I wanted, but when I selected Debian it would only load the command line.
Second try: Reinstalled but this time with the netinst version. I only got a black screen where I could type but nothing else.
Third Try. Tried the netinst again. This time after making the partitions I got a message that said that no EFI partition was found. I ignored the message and this time it wouldn't even load Grub. only a command like interface with grub rescue or something.
Not once did I get an error during the installation. What am I doing wrong?
During the first installations it didn't ask me for that.
I assume the problem is that the EFI partition got corrupted or is missing for some reason. If that is indeed the problem, How can I solve it?
The system will only boot windows if I enter the boot menu, but only that way.
Don't know if this helps but here's a screenshot of the Disk Management.
Please help me I'm desperate.
