all was fine this weekend. up until saturday when i installed the most recent updates.  I cannot let them auto install as i have to be near wifi and have to have a chance to save my work first.

 

ok so now here is my problem. the install goes perfect, everything else was fine, windows needs to restart... so I told it to restart later so i could finish my other work that i was doing online. after all of that I shut down normally and take my machine home to discover upon reboot that it goes to a black screen...my first thought of course is to troubleshoot it with the install disk. I load the install disk, go into troubleshooting tools and browse files. at this point i discover my c drive mounted as e and the system reserved that windows makes for the boot manager and things is mounted as c. after changing this in the registry settings through the same boot disk I am able to boot but instead of loading my account it shows my name with a missing profile pic.  no matter what password i give it either sits stuck on the word welcome or preparing windows but never logs in. if it logs in then i get a black screen with only my mouse displayed and am able to move it but never get anything else.

 

I am able to use linux on another hardrive to go in and backup my files if needed but is there any other option besides complete reinstall of windows? I do not have time to sit at burgerking for an entire day just to reupdate windows especially if it is indeed the update that caused this.

 

to further complicate things I have to download my graphics driver through linux and install manually because the builtin screen is crack making it very difficult to read anything which means I absolutely have to use an external screen.   in order to do this i used legacy win 7 d45rivers as those were the only ones to work before i upgraded to 8.1 from 7. might this cause the issue? if so what options besides pray win 8 legacy drivers work on my graphics card is there

Let's start with a couple of bootrec commands

Open up the repair tools and select the Command Prompt option.

 

Type these 3 commands exactly, pressing Enter after each one:

 

bootrec /fixboot

bootrec /fixmbr

bootrec /rebuildbcd

 

The last one asks a question about installations to select - select "All" by pressing A and then press Enter

 

Let us know if that works and we'll move on from there.
