    Lenovo Ideapad 305-15ibd weird problem

    Hello

    this laptop came to me with "no display" "no boot" problem.
    i changed kbc and programmed both kbc and bios and i got the laptop to boot

    here is the problem :
    when i change settings in bios from uefi to legacy laptop restarts and wont boot again till i reflash bios file.
    i tried couple of bios and ec from this from and other places. still the same
    and i found another bios , in this file legacy was enabled but graphic was uma only when i changed that to switchable graphic, laptop restarts and wont boot again.

    any idea?

    board model :
    LA-B091p Rev:2.0

          this laptop is for a customer and the hard disk is full of files and has a windows already, it boots with legacy support only, otherwise i have to back up the files then change the partition table and install windows again.

              i think its the one that i backed up from motherboard
              or maybe this is the one.
              i never had this problem is it possible its not the bios file ?
