My computer wont boot when I set my sata configuration to raid.

[Radsaw_films]

I just built my computer with an M.2 SSD as my boot drive and everything works fine except now I want to install two 3 Tb drives in raid 1 for my storage but as soon as I change my sata configuration to Raid in stead of windows 10 booting it freezes on a screen that reads please insert bootable drive. Any suggestions?

This is a guess, but I suggest you google the difference between MBR and GPT, then have a look at your motherboard manual to see if you accidentally have a mixture of the two on your PC

You need to set the system to RAID first, then install Windows, then setup the RAID volume on the other drives. You can set the option to RAID and not actually setup the drives in RAID like that boot drive.

You need to boot into Windows safe mode. The problem you are having is because Windows is trying to boot with the AHCI driver and not the RAID driver.

Once in safe mode, it should sort itself out and be fine on the next normal boot.

I had exactly the same problem.

I was actually able to figure out a solution that worked. I enabled "Windows FastBoot" in the BIOS and it booted up no problem then I initialized my drive and it works no problem. thanks for the suggestions.

If you installed windows with sata configured as IDE there are no drivers or place holders for your AHCI or RAID. Microsoft missed the ball on this and didn't include it in Windows Repair either. Usually you can boot into safe mode to fix it but if you can't you will have to get into bios put SATA back into IDE boot into windows and then fix it.

go into regedit and modify the hex for RAID - the path is:
HKEY_LOCAL_MACHINE -SYSTEM - CurrentControlSet - Services - iaStorV
(modify REG_DWORD "Start") from "3" to "0"
or if you prefer AHCI mode go into regedit and modify the hex for it - the path is:
HKEY_LOCAL_MACHINE – System – CurrentControlSet – Services – msahci.
(modify REG_DWORD "Start") from "3" to "0

reboot and change bios to RAID or AHCI (whichever you chose to change in regedit) and you should be good to go.
