I have a Dell E6250 laptop. I originally purchased it with Windows 7 and later upgraded to windows 10.
After some months of recurring BSOD issues that I never successfully diagnosed, the machine stopped being able to boot windows.
I created a windows 10 recovery USB stick from another, functioning computer, and I was able to reinstall windows on the Dell by booting off the stick. Everything appears to be working fine...
However, now when I restart the computer it freezes at a black screen with a blinking cursor prior to Windows booting. I am unable to enter any inputs here.
I can continue to boot windows normally, but only when I use the memory stick: Hitting F12 upon CPU initialization and choosing the option UEFI: INT13(RAID,0x80). There's another option UEFI: INT13(,0x81) that fails to load when I choose it.
How can I fix this computer so that it is successfully able to boot off of its internal hard drive rather than relying on an external memory stick? How do I troubleshoot the black screen blinking cursor issue, given that I can get the computer to boot successfully?
