That out of the way, be sure ALL USB DEVICES are unplugged. Be sure your USB BIOS settings are at defaults.
If not, go get your W10 install and repair USB stick, boot that and try an automatic repair (how is on google.)
If that fails, try a clean install. The blinking cursor is usually a blown OS.
Suddenly my Dell Inspiron 5110 laptop won't boot, after dell screen, just a cursor blinking in the top left. I tried restart several times but no use.
I had run the diagnostic tests, test results are passed. Also i did Thorough test mode on Hard disk, results are passed.
Just want to add, i am running windows 10 in this laptop from 2015 (no issues till now). And yesterday i have uninstalled the Renesas USB 3.0 eXtensible Host Controller -0.96, because its not working and i reinstalled it, still that slot didn't work. So, after that i shut down the system. Next day this thing happens, won't boot after dell screen. Is this problem related to this ?
Can any one help me on this issue ?
Thank you.
