I had Lenovo laptop with Windows 7 OS.
I want to install "Kali Linux" by removing windows 7.
So, I made bootable pen drive of Kali Linux.
Then I installed it.
Installation was successful,
but while installation, It shows some message about GRUB but I didn't know any thing about it.
So I underestimated it, and That was, I have to choos where to install GRUB boot loader.
So at first I install it in internal hard drive, and I restarted computer but, it again asked for re-installation.
So I re-install the Kali linux and in second time I choose the option to install in pen drive.
Then after restarting again they asked to re-install, so I had removed pen drive and I neviget to bios or boot menu, and I disabled the usb boot.
And then, When I restart the laptop, It was showing lenovo logo, and black screen with blinking cursor, and nothing else,
I tried to open bios menu, but no function key worked, f1-f12, and DEL key and Holding Shift key, etc, I tried much to nevigate into boot menu, but I didn't succeed, and also,
I made bootable dvd of linux mint, but It also doesn't work in my laptop.
Now what to do, Please Help me, I'm stuck since 4 days…
.
Any answer, wrong or write, will be highly appreciated.
