HDD boot trouble in an A1200D, need urgent help

[Amigaz]

Installed my first ever 2.5inch 2.1 gig HD in my A1200D yesterday which I had ordered from www.analogic.co.uk, it has W 3.0 installed my problem is that my comp. won't boot from the HD, I can hear the HD spin up and work and HD light flashes but then stop work but keep spinning and just the insert disk animation screen appears both after warm/cold boots.
Have tried rotating the IDE cable 180 degrees but still the same thing so I wonder if this is a typical problem if the HD has no boot partion (the seller forgot to fix it) or is there a special procedure for booting from my HD? never had a HD in my young days when I had an A500 because they cost a minor fortune back then so I'm a pure newbie in this case
Extremly grateful for help!

my machine:

A1200 desktop, standard, never opened

Thanks for the reply.

I didn't twist the cable just rotated the connectors at both ends and then fitted them again to the HD and IDE.
When I got this Amiga I didn't get anything with it
so no workbench disks, bah
Got it for free from a guy on Ebay in England because he sold me some games that didn't have the manuals so couldn't play them because of the copy protection.
I do have all WB2.05 disks except the install disk, any way I can analyze the problem with WB2.05?
Since I'm still an Amiga newbie I must ask you what a "logic board" is?
I'm quite an expert on PC's and Amiga's are older/"simpler" but not easier to deal with, hehe

Just want to add that there's also four free pins left over on the HD, any chance that there's a jumper there missing like on a PC drive?
Am also pretty sure I've seated the connector firmly onto the IDE pins on the mainboard.

Many thanks you guys for the quick aid!

Will try all of these options, hopefully they will solve my problems, have some games here which are HD installable, arggh

the IDE cable hasn't a red line, must be a cheap crap cable, lol.
Read about the "1" and red line in another thread on the forum but couldn't find mine.
Whish I knew how to attach an image in this message, have taken pictures of my installation so you can see my cable etc.
