Well, yes. That's what "Active" means: bootable. And there can be
only one. It's been this way for many, many years.

No, of course not.

Boot the computer from another disk and remove the "Active" label from
the incorrect partition, and put it where it belongs.

Please, what do you mean "Boot from another disk"?
My PC run on Windows Vista has only one disk with two partitions C and D,
because of some problems, I decided to change the D partition to "active" in
order to install another OS from a CD disk on the D partiton. After loading
the files from the CD for the installation is finished, it came up with
notification that there no hard is found!
Normally I can change the "C" to ACTIVE again through the Diskette Drive,
but nowaday there is no Diskette Drive on the new PC.
What should I have to do fix that, Thanks

Floppy drive, CD, etc. Anything other than the internal hard drive.
