Slow boot time after second SSD

Question

I have the dell inspiron 7567 which had a 256GB m.2 SSD

I recently added a 1TB sandisk 2.5 inch SSD making it having 2 SSD.

The boot time has increased to 45 seconds from 10 most of it sat at the dell screen, this did not happen before.

I have checked the bios boot order and other people suggestions of changing the fast boot and sata configuration and it didnt work.

Its almost as if adding a second SSD has done something that has made the laptop boot slower

Does anyone have any idea?

Thank you.

Being set in RAID is probably why the system boots slowly. With one drive not a problem but that second drive is what started it all and in RAID the system is looking for the required drivers needed for RAID. And SSDs run better in AHCI. Trying to change to AHCI would mean reinstalling Windows 10. But the following procedure may help out. If you are not comfortable making the following change then reinstalling Windows with AHCI turned on may be the best solution.

Have you tried it with Secure Boot turned off? Sounds like the second drive is causing the BIOS to hang up during POST. Try tapping F12 when you see the Dell splash screen. Then select the M.2 drive from the list which will force booting from the M.2 drive. If it boots faster then you can figure that the boot order or boot configuration is possibly suspect during boot.

Thank you for replying when pressing f12 and selecting windows boot manager from uefi it did it in 5 seconds as normal. So how to I make this happen automatically?   Thanks

In boot order is Windows Boot Manager first? AHCI turned on and secure boot turned off.

Windows boot manager is first on the list.

ACHI is not on its on RAID as when i changed to ACHI in bois it crashed saying no bootable media. Any safe way to do this?

(Again suggesting that its searching the storage ssd rather that booting normally through the m.2 which hasn't been touched at all).

It's a shame that I can't add a second storage device without this confusion.

Thank you.

JOcean i cannot thank you enough.

When removing the second SSD i got 15 second boot time.

When back in 45 seconds.

Then after following your guide, I got 15 seconds with the SSD in, it fixed it!

Who knew having a second SSD/HDD would alter the boot time so much in RAID.

Thank you again for your time and fix, and i hope this helps any other people with the same problem too. :)
