Slow windows 8.1 boot with new SSD fresh install

[trak]

Hi, I recently installed a brand new samsung 850 evo 500gb in my system.

Asus p8z68 v pro
i5 2500k
8gb 1600mhz corsair vengeance lp
1.5tb WD green
128gb Samsung 840 Pro

But I'm experiencing a very slow boot compared to my old crucial m4. The SSD is on AHCI mode and tested with no problems in Samsung Magician.

First I have a question about something in the bios. My first boot option is windows boot manager (I have never seen this before?). And if I put the first option to my OS drive I get error message "reboot and select proper boot device or insert boot media in selected boot device and press a key".

It seems the boot option must be set at windows boot manager, or else I cant boot at all.

So when I boot my PC I get another screen that basically slows the boot by at least 40 seconds:

Never seen that screen before, on my old crucial m4 it was super fast anyway. I have no problems with my computer otherwise than this slow boot, so I am really wondering what this could be.

Thanks.

is the old crucial ssd still connected?

Ideally connect the samsung to the lowest numbered SATA port . Usually 0 , but sometimes 1

I would reset the bios . , and if it doesnt boot well after that then reinstall windows

No, the crucial is removed.

Its connected to the first Sata 3 port yes.

But why reset the bios? The bios boots fine, but that windows screen after the bios is the slow part.

UEFI BIOS are quite complicated bits of software compared to old style BIOSes , and much more prone to small errors .
If you have a BIOS reset button then use it . If you dont then take the battery out for 10 minutes
