How to Change Boot Priority in ASUS Z87 series Mobo?

[Susmoy Paul]

I want to install Win7 from pendrive. But can't change the boot priority neither in EZ mode, nor in Advanced Mode.

In EZ Mode, there is a option to change the boot priority in the lower part of the screen. I change that everytime, but nothing happens. :/

In advanced mode, Under the BOOT tab, I change the 'Boot Device #1' in pendrive ... but nothing happens here too. That means, after quitting from the bios ... PC restarts and the Win7 logo comes. There's no opotion for a CLEAN SETUP. :/

So do I've to do another things like "DISABLE FAST BOOT, ENABLE LAUNCH CSM', 'DISABLE SECURE BOOT' (well, I can't find this secure boot option) :/ ... or something else?

Waiting for your help guyz ...

Configuration:

i5 4570
ASUS mobo z87k
WD Green 3TB HDD, BLUE 500 GB HDD
Ripjaws 8GB Ram
Gigabyte GTX 770 OC GFX Card


**** Another thing ... the clock in my PC ISN'T running okay all time. Sometimes it changes, that means the battery of MOBO is not in good condition. Is it necessary for the change of boot priority?

Are you sure you are saving changes before exiting because this is very surprising

Yes ... after changing the order, I click the exit button. Then I click "SAVE CHANGES & QUIT". I go to that option ... & there it is ... "There ISN'T any changes MADE, wanna quit?" 🙁 I quit, but nothing happens.

So I want to save the change, but the mobo itself doesn't wanna do that. But it save the changes when I go for X.M.P. mode or other things! :/

I have a similar problem with my Z87 pro... Every time I have to start it up... I always just do boot override on my sandisk.... Now I just always leave my pc on with sleep mode

Try to boot up without HDD, only with pendrive.
We will see if it will be detected.
