Boot Order Resetting

[tray262]

Hello,

I am trying to figure out why my boot order keeps resetting. I have an external HD that is plugged into the Esata Port sata0 and my internal HD is set to sata1. I want to change my boot order to choose sata0 when its plugged in. So the order would be sata0, sata1.

After I change the boot order it works fine but when I turn off the external, then turn it back on and try to boot back to it the settings revert back to sata1, sata0. Any suggestions?

I am doing this for a classroom where students use externals to boot into different OSes. All the stations are identical and there are 3 stations where we have no issues. When the externals are plugged in they boot directly no problem.

I plan on checking the Cmos battery but the PC's are only 2 years old.

Are changing the boot order in the BIOS or are you just changing the boot priority with a "F" key during boot?

maybe not saving to cmos correctly?

The first thing you have to do is restart your computer and enter the BIOS. You can enter the BIOS when you see a message such as “Press FX to enter setup” or something similar.

Hello thanks for your responses

Yes I am entering BIOS and changing the boot order and pressing F10 to save changes. Its strange because it is saving them and after a few restarts and unplugging the Esata port and re-plugging the settings revert.

Looks like all the stations are not using the same motherbd or if they are some are on a different firmware version.
