Two hard disk, windows 7 64bit and windows server 2003 32bit, bios don't see windows 7 disk?

Sorry but I tried and search the forum and couldn't find solution to my problem or similar.

My Problem is,

I had a pc running server 2003 32 bit on SATA2 drive, The machine went in junk I took the drive out which has OS partition and 2 other data partition on it.

Got another machine and decided to go with windows 7 64bit for more memory support, this machine has simple swap SATA drive system, I connected the old server 2003 drive in bay 2.

before connecting server 2003 drive the system was booting from windows 7 fine, but soon after connecting server 2003 drive, the bios does not see the windows 7 drive, and system boots from server 2003?

I went into BIOS but it doesn't show the windows 7 drive for selection?

Any guide, Please? I want to boot from windows 7, and want to format windows 2003 system partition and keep its other data partition of drive in bay 2.

  1. Go into your Bios and set the Win 7 hard drive as your first Boot Device.

    That is what I had in mind,
    But the problem is it does not show the windows 7 drive in the bios, and the bios does not provide and option to detect the hard drive, it kind a choosing it by itself.

    I have latest updated bios.
    The machine question is IBM ZPro 9228.
  3. Guys any help on this, still puzzled how to reflect the windows 7 drive in bios, It doesn't give me any option to choose.
  4. pull the old drive, boot into 7 and then reinsert the drive and format it.
