Boot manager missing after BIOS update

Story of my life..I'm confused. I updated my BIOS as I was having a problem mentioned in one of the updates. I was using the Easyflash2 by Asus and the update succeeded but when it re-booted I got the awful news..boot mgr missing. Would my best bet be to just re-image? Thanks for your help.

Hello mate.



Start by having a look through this tutorial at the link below, if doing the 3 separate startup repairs doesn't sort the issue, you may have to use the outlines in Option Two to mark the Windows 7 partition as Active and then do the startup repairs again; be sure to post back with any further questions you may have and to keep us informed.

What is the SATA controller setting now in BIOS?

It was likely reset to default which may be different than the setting in which Win7 was installed. If it's now IDE mode, try AHCI instead - or vice versa.

Thanks for your help, but none of those things seemed to help this time around. I ended up just loading everything back from scratch. I was able to re-image, so it wasn't too bad. I really, really appreciate both of your responses. Bill

Hello again Bill.


Good you have an image to go back to; have a look at this tutorial at the link below, this is from that same tutorial and I do this myself, it comes in very handy!

How to Use the BCDEDIT Command Line Tool
warning   Warning

IMPORTANT: make a backup of your bcd file first. To do that, type:

bcdedit /export C:\SAVEDBCD

This will create a file c:\savebcd which is your boot entry backup.
If you mess up, you can always undo changes by:

bcdedit /import c:\savedbcd

Do you reset the BIOS, before installing Windows 7 the first time?
