Success with Arch, Fail with Windows

Question

So I successfully partitioned Linux, and got everything working(internet, drivers, the whole shebang), as a dual boot with windows. However, now when I try to boot into Windows, it gives a /boot/bcd error, saying that I should use an installation disk to repair it. When I try the installation disk, it says that the disk is not compatible with this version of windows.
I know that I partitioned the HHD correctly, and here is the output of lsblk:
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 931.5G  0 disk
├─sda1   8:1    0   100M  0 part
├─sda2   8:2    0 752.3G  0 part
├─sda3   8:3    0  1007K  0 part

└─sdb1   8:17   0 232.9G  0 part

Please help, I have a LOT of extremely important data on Windows, so please reply quickly and accurately. I don't mind if I have to delete Arch to get windows working again, windows is REALLY important, so please help me save it!
Thank you for your help...

I'm using Windows 7 Ultimate, dual booted with Arch Linux.
I used by BIOS to boot into the Arch Linux iso cd I created, and then installed it from there, and now I have Grub to boot into things.

I thought it would be safe because I already had successfully installed Bactrack 5 R3 into it's own seperate partition. I soon tired of seeing the script kiddy community, so I decided to go to Arch. So, I removed backtrack from the partition(Windows disk managment), so that it was about 179 Gb of free space. I then made sure that windows booted(it did), and then popped in my arch linux cd. I installed arch(no easy task, but this OS is definitely worth it), and then, for reassurance, booted into windows. When I tried(selected to boot from GRUB menu), I got the /boot/BCD error, and when I tried use the installation disk, and go into repair mode so that I can access the cmd(only half-way decent thing about windows, I think), it says that "this version of system installation disk is not compatible with your version of Windows". The problem with that, is that I tested it before I installed Arch, and it worked fine.
Thanks again.
That a guid partition, not an mbr one.  But win7 should be able to boot from that, I think.  Grub has some sort of ability to boot windows with grub bootloader.  You're not using a 64-bit version of Windows installer on a 32-bit Windows?  You can boot from the 64-bit CD to override that.
