Hi Guys,

I installed Kali Linux with Windows 7. I wanted to dual boot both the operating systems. So I used the option of Grub Loader while installing Kali. When I try to boot Windows 7 a blue screen comes up after booting and the system restarts. Kali runs fine with no issues but Windows 7 is not.

Here are some details that I could extract from Kali Linux.

fdisk -l -u
