I have a Lenovo X1 Carbon Type 20FB (4th Gen) that will not boot into windows, it hangs after loading aswbidsha.sys . When trying to boot to the Windows 7 Pro CD it displays a black screen with a white responsive mouse pointer. Keyboard does not appear to be responsive. I also experience this same behavior when trying to boot to a Windows Defender Offline USB drive. Lenovo hardware diagnostics pass. When pressing f11 from BIOS interrupt to repair it loads windows and gives black screen, no mouse. I used to use UBCD but my USB UBCD drives BSOD now as it has been a very long time since I used them. I am of course trying to avoid telling client we need to reset and install new, he has data backed up but no image. Any suggestions? Thank you!
