My HD isn't plural. My HDs' is plural. But yea, I know you didn't mean it literally.
Anyway, My brother had the same problem on his computer (the one I am using at the moment, seeing as how mine died).
We tried to install linux as well after windows wouldn't.
We got the same results you do now.
After a while, when I was out, my brother some how managed to install XP again on that broken disk. I have no idea how he managed to do it.
The only side effect he has, is that the Windows XP cd has to be inserted in the cd-drive in order to be able to start the OS.
It sounds odd, but somehow it is true. I have no idea how come, except that maybe it didn't install properly and need to read files from the cd. But then you wouldn't get the "no boot device found" message.
However, as his BIOS is password protected, and neither me nor him knows the password, it could mean that the HD is not selected as a boot device and by bypassing the cd boot, it automatically jumps to the conclusion that it should use the harddisk to boot from, because it never actually did boot from the cd (otherwise the windows installer would run).
I do not know, however, if your question regarding whether the disk is broken or not, is a true question. Seeing as how we (my brother) was able to somehow install windows on his broken disk.
Broken, in the sense of what you described in your previous post.
Anyway.
You should try connecting the harddisk in a different computer (and make sure it's set as slave, if running IDE (on SATA this is not necessary) and see if it pops up in "my computer". Also if it does, if you can read files or if they are corrupt; which would indicate the disk is truly done for.
But anyway, BuhBYE!
