My Acer aspire one laptop was having startup issues and would try to configure windows then fail and wouldn't succesfully load a profile it would just turn blue and do that repeatedly so I did the startup repair and it said everything was fixed but all I've been getting is a black screen for two days
You need to edit your post and put it in the main field, you tried to put it all in the title and that gets cut off.
If Windows goes into the loop where it keeps saying it needs to be repaired, try that, if that fails, you likely will need to restore the system to factory defaults.
Another thing to check is that the hard drive is often the cause of this error, if the drive goes bad, the Windows files can't be read and it won't boot. Boot of a utility disk like Hiren's and run the disk check utilities it has, Seatools should scan any brand of drive, not just Seagate.
