Guest Neal_Ewan Posted February 12, 2019 Posted February 12, 2019 Hello All, Nice being here...i hope to find solution for my PC I use a dell precision M6800 with a windows 8. I just replaced my motherboard. it worked for a few days until i turned it up one day and it displays a black screen with the error message " invalid partition table" i tried all i could including trying to repair the boot sector automatically with the installation disk. but it says windows cant repair OS. I later got help and the boot method was changed from "LEGACY" (which is the default boot method) to "UEFI boot with secure boot on" i didnt have time to confirm this before the black screen error...but now with this new boot method , i cant play any videos...all video apps i've installed always give and error message when i try to play a movie but audios work. i would really appreciate it if anyone can help me asap with resolving this issue. thanks in advance.
