black screen with a blinking underscore

[winxp]

so the problem with my HP laptop started with an electricity cut out where there was no battery and when the electricity was back the laptop didn't power on so it was a problem with something in the power after i got it fixed the laptop started acting weird where the "black screen with a blinking underscore" started to appear and per vented booting unless i press any button several times and when i got it to boot on start up it started to open multiple windows of whatever my default browser is and also opening many new tabs. somehow this problem vanished(except for the black screen with a blinking underscore) after desambeling the laptop for cleaning the fan.

 

- now the main problem is when i formatted the c drive which had the windows 7 to use only windows 10 on my d drive it become unbootable with black screen with endless blinking underscore, even when i tried to boot from a CD it sent me back to this black screen, what should i do?

First thing you need to do is learn how to write a sentence using the proper punctuation.  Between the two paragraphs, there is only one period and one question mark.  Sorry, but it's a little hard to read and understand when everything sort of runs together like that.

 

From what I could make out, try creating a Windows Media Creation Tool first.  Then try using the tool to recreate, partition and format the drive and when that is done, then you can do a fresh install of Win10.  Considering everything else is okay, that should get you started.  Good Luck.
