Hi Mohamed!
This is off the cuff so you’ll have to experiment a bit! Anyway if you think you’ve done something wrong you can alwas EXIT the Bios without saving. As well I use Win7 and the Bios in French so I am trying to translate the terms as best as I can into English.
OK! Leave the “My Book” connected when you shut down.
Boot up and keep tapping DEL, computers differ and you may have to tap in order one of the following if DEL doesn’t work…F8/F4/TAB. One of these will open up the BIOS. Along the top line go to BOOT, in the drop down you will see the order of the boot. N° 1 needs to be your Hard Disk. I reckon it’s N°2 and WD My Book is N°1 !!! Click once on he N°1 which should open up a similar window (If one click doesn’t do it try two) Click…as before once or maybe twice…on your HD. and exit. Your HD should now be N°1 with a bit of luck. Exit with save…F10 I think!. The reboot should start up immediately. You may also see “USB boot” as well. But remember your N°1 BOOT is your HDD not your Mybook!! Anyway you can play about with BOOT because you can always return and follow the original path (DEL etc) above to put things back to their Default set up. BUT Always NOTE what you have done just in case. You will also find that one of the Keys you tap will bring you a list of things you can do if your Comp’ isn’t doing what you want. So you can also play about with this.
I’ve done all of this so I know it’s OK. My problem was the non compatible version!!! If you are still getting the sma problem then do as I do. Shut down, disconnect your WD My Book and reconnect AFTER you comp’ Boots Up with Win7
Down in the right hand bottom corner you will see a series of Icons, Loudspeakers, ADSL connection etc. On the left is a small arrow which will show you the Icons not displaye, one of which if your WD is connected will say, if you put your you have to go throughthis before disconnectingcurser on it, Disconnect with safety you My Book. With Win7 you have to go thro’ this before disconnecting your MY BOOK. If not as I found it messes up your BIOS set up. I left this alone at the beginning of this post as it needs to be connected to show up on the BIOS. But from thereon in if all goes to plan and you want to disconnect before shutdown, then go thro’ the procedure.
Other than that I can’t help any further SORRY!! Keep me updated.
