I'm trying to install Windows 11 on my Acer Nitro 5 laptop, but the SSD isn't appearing in either the BIOS or the Windows setup. I previously had Windows 11 on a different drive in this same system, but when I moved that drive to another computer, the SSD seemed fine. I also switched the SSD between machines, where it showed up normally and I formatted it, but now it won't show up in my Acer. Is there a way to resolve this issue?

I noticed you mentioned the model as an AN515-58. You should be able to find the drivers you need on Acer’s support site. Just a heads up, different browsers behave differently with those links—try Chrome if Firefox isn't working for you.
When you check the BIOS, be sure you’re looking at the storage section instead of just the boot options. If the SSD doesn’t appear under storage, it won’t be accessible during the Windows installation. If it does show up, you can change it to AHCI mode right there to avoid driver issues later.
It sounds like your SSD issues might be tied to Intel Rapid Storage Technology (IRST), which is similar to RAID. If your BIOS has this option, try switching it to AHCI mode. If that's not possible, you'll need to load specific drivers during the Windows installation—which you can find on Acer’s support website.
