how do i change my boot drive

i had two hddrives. two windows in these drives. one having win7 x32 and the other win7 x64.

now the one having 32bit windows has jst stopped working. bt my boot drive was drive C of that hdd. now every time i try to install a new windows from a setup folder in my harddisk (dont have a bootable windows 7 dvd rite now) it stops, saying
""Windows setup cannot find a location to store temporary installation files. To install windows make sure that a partition on your boot disk has at least 812 MB of free space.
Error Code 0x80070490.""

Do you want to start Win7 on the remaining HD or clean install over it?

To start it mark C Active and run Startup Repair - Run 3 Separate Times.
Partition - Mark as Active (Method Two)
Make sure HD is set first to boot in BIOS setup, after DVD drive.

To install over it boot the DVD, choose Custom install, use Drive options to delete C, create a New partition there, Format and Install.
I would back up my data on the HD as it can sometimes disappear, and of course everything on C will be deleted.

You said that you had 2 HDDs, but that picture only shows one and that HDD starts at I: (W7 64 bit?).
I assume that you actually want to install W7 on the other HDD (the one we can't see).

I'm not sure how you are going to install W7 without a DVD (or USB).

Exactly where did you have W7 32 Bit installed ? Where is this other hard drive ? Did it die ? Is that what you meant by ( NOT WORKING ) that`s probly why you can`t boot to it. Where is C:

Greg can post you a link to download W7 and burn to dvd.

i have 32 bit win 7 installed in my C drive. Now i tried specifying from BIOS to boot from 64 bit windows which is in drive I but everytime it says ""bootmgr"" is missing. but if i tell it to boot from 32 bit windows in drive C it boots ok. i gave higher priority level to the 1000 GB harddisk from BIOS and it again says bootmgr is missing.

Can i boot from I now?? and my windows is constantly showing me that the deadbeat harddisk is gonna die(!) again. so a fast reply would be helpful plz.

Do you have blank cds ? Download and make a Windows 7 Repair Disc 64 Bit. That is the HD you want to get booting, correct ? Try to download a pre service pack 1 version as the version with service pack 1 seems to be throwing up an incompatable version error message. Boot from that cd and it should find your I: partition. You may have to do it more then 1 time. I`ve done tests and sometime it takes 1 attempt other times it takes 2. Keep trying. Why don`t you unplug the C: hard drive b4 you try. Or just disable it through the BIOS.

Follow Gregs instructions.

I gave you the steps to start the non-System HD here.
Unplug the other HD first:

When Win7 on I starts, replug back in the other HD, set preferred one to boot in BIOS first (after DVD drive) then boot the secondary by tapping BIOS one-time Boot Menu key at boot.
