In June, I created a bootable USB for My old laptop to install ubuntu over Windows, It worked but on 15 June I accidently booted into ubuntu on my main laptop but I thought ok, restart but after boot into Windows, I got met with this screen in the image Credit And yes, I didn't know them I checked everywhere but it's setup was already ✅ done, so the manufacturer knew the key but thought it is Garbage , but it's not, so I ended up reinstalling Windows and QUICKLY DISABLE BITLOCKER even tho the key was in my Microsoft account So it's like putting water all over on your 3 years of Hardwork
