This post has questions about upgrading to windows 10 pro and windows 10 problems or potential problems if the upgrad was made using the default bios setting or a different bios settings. Please repost this on the bios board if it more appropriate there than on the windows board.
Many people have upgraded mobile workstations from windows 7 pro to windows 10 pro.
These updates were likely done without changing the default bios settings unless the end user had received information about potential problems.
The default setting for windows 7 pro was legacy mode.
Windows 10 pro does not work in legacy mode
I was reported that HP had found that mobile workstations (zbooks) upgraded from windows 7 pro to windows 10 pro may have problems if they were upgraded in bios legacy mode.
HP had indicated that a proper update should be done by first changing the bios from legacy to uefi hybrid using windows 7 pro.
Then and only then should the windows 7 pro be upgraded to windwos 10 pro to avoid later windows 10 problems.
Then after upgrading windows 7 pro successfully to windows 10 pro the bios setting should be changed from UEFI hybrid to UEFI without CSM or UEFI with CSM?
Please indicate whether the above is correct or incorrect. If a portion is incorrect then please indicate what is correct and what is incorrect.
Please provide HP notices or white papers about this problem upgrading wndows 7 pro to windows 10 pro
Please provide information on what should be done with mobile workstations that had been upgraded in legacy mode. That is if there are no noticable problems or if there are any problems.
