Sir, I had upgraded my Acer Aspire Laptop (CORE i5 - 4GB RAM) from Windows 8.1 to Windows 10 recently. As it was running very slow, I decided to do a 'clean reset'. By mistake, the recovery partition also cleaned. It then went to a blue screen saying "Your PC ran into a problem and needs to restart. We'll restart for you" and appeared the error code INACCESSIBLE_BOOT_DEVICE, and it is keep on restarting again and again with the same error.
I dont have windows 10 System Recovery Disk, but I have Windows 8.1 System Recovery in USB. However, the system is not booting from the USB. When I tried to change BIOS Boot order, the system asks a password, but I didnt give any password.
I will be extremely greatful If anyone can fix this problem.
Thank you
