Hi all, hopefully someone can help me with this issue Just today, my system was unable to boot. It was working fine this morning and then had a crash and now will no longer get past the alienware logo screen. I have tried numerous repair options so far. Ran the pre-boot diagnostic. No issues were found. Try to reinstall Windows. However, the installation is frozen on numerous occasions. Reset, the bios to default settings. Not sure what else to try as now I can’t even boot into safe mode.
Aurora R11, won’t boot, unable to repair
