Yes it will If you know how To set it up

You are assuming the .iso file contains a bootable image.

That is distributed using an .iso file. There is no OS within it. It
is not a bootable image inside the .iso file. It is a *data* image.
Microsoft expects you to burn the ISO to a CD-R to then load the disc
into an optical drive (or you can use a optical drive emulator to mount
the .iso file) and use an existing and running OS to read from the drive
for that disc to load and execute the installer within. It is just a
data image, not a bootable image.

The OP has not yet identified just what is inside the ISO file. "ISO of
Win98" might be a bootable ISO image (i.e., a clone of an instance of
Windows 98), it could be the installer disc, or it could be just a bunch
of [data] files copied from the OS partition into the image. ISOs are
also archive files.

It's been awhile since I last used VirtualPC 2007. As I recall, you had
to go into the properties of the VM to attach a physical optical drive
(in the host OS) to then see it inside the guest OS running in the VM.
Just loading a bootable disc in the optical drive which is only known to
the host OS won't make it available within the VM. Before getting too
far into diagnosis, we need to know if the the VM actually has a mapping
to the physical optical drive.

As I recall, you cannot attach a physical optical drive in the host OS
to the VM until you stopped the VM. That is, device changes required
the VM was not loaded; else, device options would be grayed out.

Virtual pc 2007 Read ISO As if it was a Newly Burn Bootable OS Disc On
D:\

Only if the .iso file is actually a disk image for an OS; i.e., so the
ISO is actually bootable. The OP has not identified *what* is inside
the .iso file.

The OP said, "play with the bios and it just won't boot from a virtual
cdrom". I don't remember there were any BIOS settings inside a VM. You
changed devices in the VM settings, not in an [emulated] BIOS.

When you insert a bootable disc i.e., you will have to hit the trigger key
in the blind.

Or a floppy either for that matter.

I doubt the OP has an .iso file containing a bootable Windows XP image
on a floppy drive so I focused on the likely media type: CD/DVD/BD disc.
