Some close the barn door after the horse has gone comments, which may be helpful if and only if you try this again, and assuming you re-install Win7 after getting the Win7 disks, I make these humble suggestions ....
First, does not win7 provide the capability of making one's own re-install / recovery disks without having to order them ? Ergo, before installing another OS (any OS) it makes sence to do that first.
Second, before installing any OS in a dual boot with windows7, backup the MBR used/setup by Win7. I know, this is obvious, but many users can not be bothered to do so, and this is VERY important.
I blogged a bit on this (albeit from a different perspective) here:
Installing Windows7 after openSUSE-11.4 - Blogs - openSUSE Forums
... now in my case I was backing up the openSUSE MBR, but AFTER I had win7 installed, I IMMEDIATELY backed up its MBR. Why ? Well, sort of common sense (I thought).
One can back up their MBR on windows7 by booting to a liveCD, and then open a terminal and with root permissions very carefully (very very carefully) type:
and keep the file 'my-win7-sda-MBR-backup' on a USB stick and never lose it. I did say type that command very carefully? No ?
dd if=/dev/sda of=my-win7-sda-MBR-backup bs=440 count=1
If for some reason one's breaks their openSUSE such that one can not boot from Grub, one can always boot from a liveCD, insert the USB stick, and then load the file 'my-win7-sda-MBR-backup' onto the MBR by typing very carefully (very very carefully) the DIFFERENT command:
I did say very carefully ? Do NOT get those commands (nor indeed the of and if arguments) reversed. Its very important to be very careful.
dd if=my-win7-sda-MBR-backup of=/dev/sda bs=440 count=1
and that will restore the windows7 MBR so that windows7 can boot. Note one might also have to manually change the active partition from where ever GNU/Linux had it located to where windows7 needs it, and visa versa.
I am assuming above 'sda' is ones hard drive with Windows7 installed.
