First of all, I am not a newbie to computers, but unfortunately, I have no idea how to solve this. Today, I turned on my Asus Eee PC, and an error message showed up on my screen saying bootmgr was missing. I tried a few ways to fix it and only found out it came with another message saying 'UNMOUNTABLE_BOOT_VOLUME.' I have no idea why this is happening and how to fix it. Plus, I don't have any system restore points. So, can anyone help me with this? Thanks in advance!
The fact your Asus Eee PC won't boot up could be caused by many factors, such as corrupted or misconfigured BOOTMGR, damaged boot sector, bad sectors, outdated BIOS, system update issues, etc.
