I have an Acer Aspire TC-220 ES61 running Windows 10 x64 on a 1Tb SSD and a 2Tb HDD for apps and storage.
I decided to check the Acer drivers page for a bios update since I tend to keep drivers updated and perform my own maintenance tasks, I like to work on my own computer and build them also.
On the Acer page according to my model I noticed a bios update that was dated 2020/01/25 for P11-A4 version.
Now I know the date was changed by Acer because it was a couple years since my last BIOS update.
So upon completion and rebooting I get the BSOD "Your PC Ran Into A Problem And Had To Restart" StopCode:Inaccessible Boot Device
I've dealt with this error once before, the only way is to wipe my drives and clean install Windows 10 from scratch. None of the Windows repair options work it's a loop!
I hopeless boot loop! I managed to get back into Windows via Safe Mode and attempt chkdsk command which worked, however now the drives were corrupted! I find chkdsk useless and ends up making things more complicated, my DVD drive showed up as CDROM drive, my 2Tb HDD disappeared from Windows completely and my keyboard lights even started blinking on and off at one point. Also upon shutting down Windows everything turned off except the power button light, forcing me to hold down the power button until it turned off. I am in the process of wiping my drives using a bootable partition software, after I made a Windows 10 USB via media creation tool. It's a compete mess!
