Switching from IDE to AHCI is a fairly common thing to do and the need
for that has been around a long time. I guess ever since AHCI came
out. I think I did that switch back in the XP era.

More recently, same thing with going to NVMe SSD from SATA SSD. Fix in
Windows 10 was the same too, boot Windows to safe mode, then boot to
normal mode.

Now, Windows 10 being what it is, the hardest part of this is actually
booting it into safe mode. You can try to hammer shift-f8 when system
boots but it may not work.

Since you can boot Windows in IDE mode, start from there. Hold shift
while selecting restart from the menu, you get to troubleshooting mode,
select Troubleshoot->Advanced options->Startup Settings->Restart. 

System reboots, go to BIOS and change to AHCI, save and exit. System
should boot up into a menu where you can select safe mode. If things
work there, then restarting from safe mode should get you into Windows
10 normally in AHCI mode. If not, back to square one.
