While tryin to fix one problem, I caused a new one. In BIOS upon exit i hit change to optimal defaults. Now my Windows wont boot up. Tried a few things I found on internet to no avail. I dont know much about computers but I am intelligent, so if anyone could walk me through how to fix this would be great. I dont wanna have to reinstall windows and cant afford to take it to a shop. Thank you so much and hopefully we can figure it our.
