Problem with Booting!!!

[dave7sky]

HI
I have Toshiba Satelitte A215 and try to boot my windows Vista - while putting my CD and going by F12 button Boot menu i choose CD/DVD
everything goes fine till point where i need to pick disk to install it.
I see
DISK 0 Unallocated Space
but also got message - This computer's hardware may not support booting to this disk. Ensure that disk's controller is enabled in computer's BIOS menu....

Okay to get to BIOS i tried ESC button and then F1, F2 but really dont know where to go and how to do it and what?
when press F2 buton - System Utility i have menu bar - Main, Advanced, Display, Security, Boot and Exit

Old HDD is already there..... before that i tried to boot, everything went okay - everything was loaded, pc restarted and had info - please wait while windows is set up ur PC - but nothing happened - went off and i have this problem now.

maybe it will help too - prior to that my PC wouldn't load properly - was going into repair mode when attempting to fix - there was error coming up and was saying that disk is corrupted - so i was advised to boot it and install new vista....

PLEASE HELP

Error message when you try to install Windows Vista on a computer that has uninitialized hard disks: "This computer's hardware may not support booting to this disk"

Also try this, it really helps: http://tinyurl.com/28pov9t
