Debian Jessie 8.7.1 Dual Boot on Win10 Blank Screen with Blinking Curson
 

Hey guys...

So I recently decided to install Debian 8.7.1 on my second internal hard drive. On my primary drive, I have Windows 10 installed.

I did an offline install using a CD. During the install, I selected my secondary hard drive to install both the filesystem and GRUB to. The installation seemed to go smooth with no errors or warnings. When my system rebooted, all that came up was a black screen with a blinking cursor at the top left.

I restarted and entered my BIOS to try to boot into Windows. However, the same issue occurred; a black screen with a blinking cursor. I have tried to enter GRUB by holding down both right and left shift while my PC starts up and also by pressing ESC but it doesn't have any effect. Also, pressing Ctrl+Alt+F1 does not bring me to a prompt. I have tried reinstalling both the filesystem and GRUB to the secondary drive without luck.

I have an ASUS Motherboard, Intel i5 Processor, and AMD Radeon Graphics.

Any help or suggestions?

Update: My friend recommended this program: https://sourceforge.net/p/boot-repair-cd/home/Home/ and I am now able to boot into Debian. However, Windows 10 is not listed on the GRUB menu on the primary hard drive. I am still looking for a fix to this issue.

Hi jackno,

Welcome to LQ!

The Debian CD has other options under 'advanced', one of which is 'rescue'. Boot with the CD and select 'rescue'. Go through the screens until it asks to open a chroot shell. Select the root partition for your Linux installation, probably /dev/sda1, unless you split it up.

When you get the command prompt, type 'bash'. That will give you a better shell with more features. Then runwhich is where you want it.

Grub will configure it's menu to boot Linux. Then, follow this post: http://askubuntu.com/questions/56449...e-not-detected

Reboot and it should have both options, Linux and Windows.
