I had the same problem and did this and it worked with no problem....The idea is to slipstream the updated drivers into the ISO/DVD. The drivers that came with the W8.1 DVD dont work well as I was getting the BSOD upon install. 1. Download Winreducer and install all 3rd party software it requires.  Look in the howto.pdf 2. Download the latest AMD Catalyst Drivers from AMD's site (not beta).  Listed as Windows 8 drivers i think.   3. Extract the files to temp dir. 4. Copy the files/drivers from the temp dir (packages\drivers\display\w86a_inf) and the sub dir (B149756) to the winreducer drivers dir (work\integrate\drivers\x64).  So in the x64 dir you should have the cats, msi, infs, and the b149756. 5.  Run winreducer.  Make sure you have handy an iso of the Windows 8.1 DVD. 6.  After you mount your iso, you will be taken to the options and features screen.  You will see presets, appearance, features....on the top.   Leave all options alone EXCEPT the drivers location under System.  Change that to x\WORK\INTEGRATE\DRIVERS\x64.  Dont forget to change the x to your proper location. 7.  Click finish.  Save as iso. Apply.  It will save the modified iso into the winreducer folder.   8.  Burn and install.   9. After you are done installing, install the FULL driver package you downloaded in step 2 by running the setup.exe in main dir. 10.  Thank me LOL  That worked for me on an Inspiron M5030.  I hope my answer is detailed enough.  
Dell Inspiron M5030  I had Windows 7 installed and working perfectly but i wanted to install Windows 8.1 i tried a fresh install first (also tried to upgrade from windows 7). Every thing installs fine but when it reboots for the first time the windows logo comes up and "Getting Devices Ready %" Then the screen goes black. Ive tried:-To let is sit for awhile to see if it would come back and i get nothing after hours -I plugged in a Monitor with no response (also tried to close the lid to put to sleep and does go to sleep)-I shut it down and tried to boot to Safe Mode but it says Windows can not boot to safe mode because windows installation has not finished I can boot to my windows repair and go to the recovery command prompt but dont know what to do. It seems like a video driver problem the laptop has a AMD Radeon HD 4200. if thers any why to install the driver before Getting devices ready? Please Help!!
