MSFS 2000 install prompts for Disc 2, but Setup won’t let me choose the second virtual drive

A couple things to try with MSFS 2000’s disc swap prompt

Jim, MSFS 2000’s installer is pretty old-school about how it “finds” Disc 2. In most cases it isn’t asking you to browse to a folder — it’s literally looking for the Disc 2 label in the same drive letter it started from.

Here’s what I’d do, step-by-step.

1) Don’t use two virtual drives for the install
Even though you have two images, the installer usually expects you to:

1. Mount Disc 1 (start setup).
2. When it prompts for Disc 2, unmount Disc 1 and mount Disc 2 in the exact same virtual drive letter.

So if setup started from (for example) drive D:, then Disc 2 has to appear as D: when it asks.

If your software created two drives (say D: and E:), the installer may never look at E: at all.

2) Force Disc 2 to use the same drive letter
If your virtual drive tool won’t easily “swap” images in the same drive, another workaround is:

1. Temporarily disable/remove the second virtual drive, so you only have one.
2. Mount Disc 1, run setup.
3. When prompted, swap to Disc 2 on that same drive.

3) Check you didn’t accidentally mount “scenery only” in the wrong order
Some MSFS-era disc sets have a Disc 2 that is mostly/only scenery data (so what you’re seeing there can be normal). Setup still needs to see that disc’s volume label/files.

4) If it still won’t accept Disc 2, it may be looking for a specific label or file
A very common failure with downloaded images is the disc label/structure doesn’t match what Setup expects (or the image was repacked into a folder rather than a proper disc image). The prompt will loop forever if the volume label is wrong.

A few quick questions so I don’t steer you wrong

1. What exact file types did you download for Disc 1 and Disc 2 (ISO, BIN/CUE, MDF/MDS, or just folders/files)?
2. When the installer asks for Disc 2, what drive letter does it show (if any)? Or does it just say “Insert Disc 2” with no drive info?
3. Which Windows version are you installing on?
4. What are the drive letters of the two virtual DVD drives it created?

If you post those details, I can tell you the cleanest way to get Disc 2 recognized without having to reshuffle large files.
