Windows 10 won't boot on AHCI without switching to IDE then back

Looks like a drained CMOS battery from what I read.

Good thing to check.

Simple test for that, set the time and date in the BIOS if it's currently wrong. Then turn the PC off and when you turn it back on, check BIOS date and time. If they are wrong, dead battery.

Ohhh, before I formatted my PC my time and date were always messed up whenever I turned it on, and I read somewhere that that could have something to do with it... Maybe this is the case

villannelle,

I didn't get the impression that IDE/AHCI setting was changing on it's own when you went into the BIOS (which would indicate a possible dead battery as MaloK suggested. If indeed that was happening, then hopefully it is just a dead CMOS battery.

After formatting and updating from Win7 (yes I know, I still had Win7 until about a week ago) I no longer have this issue, but yes this used to happen to me before formatting!!

It didn't change on its own, I have been changing it manually every time, I go into the settings and then change everything to get it to turn on

And, just to double check, you have confirmed the BIOS (not Windows) is keeping time and date correctly?

I'm not sure why BIOS date and time would have been affected (started working correctly) after leaving W7 and going to W10

I just went to check and yup, my BIOS date and time are correct as well. It still bugs me that my PC has no issue booting Win10 when I'm just rebooting, but suddenly the settings get messed up or something when I turn it off completely and then try to turn it back on again...

This issue doesn't come up when rebooting the computer, only after turning it off and then on again.
When I first access the BIOS after turning it on, it's in AHCI mode, and my SSD is recognized as AHCI. But when I go back to BIOS to change from IDE back to AHCI again, my SSD is recognized as SATA.

Win10 Will adjust time even if it's "way off" Unlike W7. But the fact that you need to shutdown to loose your setting are indication of a bad battery.

Shutdown the computer completely light it up go to bios and verify date/time if they are not holding you can be sure it's the battery.

My BIOS' date and time are correct right now

Please confirm you followed this

You're right, I just restarted it. Let me completely power it off, I'll be back in about 20 minutes when I manage to turn it back on lol!! (Also thank you in advance)
