Erase hard drive when computer won't boot into Windows?
About 2-3 months ago, I started getting notifications that my battery needed to be replaced. I never bothered to replace it because I’d rather not waste more money on it. At some point, it wouldn’t last more than 10 minutes unplugged even though it was fully charged. A few weeks ago, I had to perform a custom installation because I got locked out and wanted to save the files (so now they’re all located in Windows.old).
I haven’t touched the laptop in weeks. I tried powering it on today, and while it does turn on, the screen stays blank and the power LED constantly flashes. I also noticed that the fans run extremely loud—something that never happens when I normally use it. The laptop doesn’t turn on at all when it’s unplugged, and it automatically turns off when I unplug it. Not sure if this has something to do with the battery, or if it’s also another problem. Really all I want to do is transfer the files to a USB or something and then erase the hard drive before I get rid of the laptop. How would I go about doing this if it doesn’t even boot to the OS? Or rather, how would I be able to fix the issue and boot into Windows 10?
