Hi all,
I updated my dell studio 1555 laptop to latest win 10 build. It did went into black screen and mouse cursor initially after couple of reboots ( weird ac adaptor error while booting even though I was not plugged in, keyboard stopped working, 4 beeps after which I did cmos reset) it worked fine. After shutting it down after completion of my work, next day when I started I couldn't see anything. No boot menu ,no dell logo , just pitch black screen.
I tried 15 seconds power button trick. But still black screen , without any cursor.

I can hear the fan running. Is the HDD curropt? How can I start in safe mode or any other without display? I have dual boot win 10 and Linux install. Never faced any issues before latest update.
Can I remove hdd, insert live usb linux and boot? I also have win 10 bootable usb.
