Emachines W3619 won't load ntldr

Check if UEFI is disabled after flash with newer BIOS version. If you flash BIOS the default settings gets loaded again. Check hard disk settings and boot settings.

Emachines will sell you one for about $25 USD.

may be you can try to fix the issue by software, and restore your system by a recovery disk. Windows Boot Genius may be available to you.

ask why?
Post in a Comment.

The short answer is no - there not a reset button. What are you trying to do?

Not if you alread have VIst installed. If it is a change to fista then all of the drivers wil have to bve updated .Sometimes drivers are not available .OK I see you alread have VISTA no problem. Just install the service pack.
