Windows 7: W7 only boots after installation disk timeout

W7 only boots after installation disk timeout

Hello. I have a Z77 mobo with a new SDD and a HDD from the old PC. At first I installed W7 to the SDD and I could only boot into it when I disconnected the HDD. When I started PC, the logo was shown for a second or so, and then it went into repair mode, the "preparing installation files" progress bar ran twice and the system booted into GRUB that was left on the HDD. I've tinkered in BIOS a lot trying to fix this, but to no avail.

Now I've decided to also install Linux (OpenSUSE 12.2) to the SDD, and hoped that GRUB2 would solve my problems. Nope, it didn't detect my W7 at all! (however, it did detect the two(?) old W7 mount points from the HDD). I couldn't even get to boot it by forcing "Windows Boot Manager" from BIOS. I tried to fix this with DVD repair, at first I couldn't get it to work by launching the DVD in UEFI mode, the other one worked, but it only messed up my GRUB2 and I couldn't boot to either system. After some unsuccesful tinkering with bootrec, I found this thread and followed what OP and the best answer guy did, which sums up roughly to this:
C:\> bootsect /nt60 C: /force
C:\> diskpart
DISKPART> select disk 1
DISKPART> select partition 3
DISKPART> active
DISKPART> extend filesystem
C:\> bootrec /rebuildbcd
Then, Windows Repair detected my installation and said it fixed the problem. Now I still can't boot into my system normally (again, it reboots after "Windows is loading files"), however, I can get it to boot after the timeout ("Press any key to boot from DVD") from W7 installation disk! I have no idea what's going on.
Here is a screenshot from diskmgmt:

The strange thing is the 128MB partition - I suppose this could have been MSR partition, while gparted shows it's a Linux partition! Is this possible, that OpenSUSE installer messed it up?
Any help would be greatly appreciated!

Have you ever had linux on this system?
because strange disc drive activity like that is a common side effect of grub.
Only mess with this if you have ever had linux/Ubuntu on it. That's the only way it could be grub.

Your apparentlly have an EFI BIOS which installs Win7 to a GPT disk, however it seems like it has been reformatted to an MBR disk so that C has had written to it the System BOot files which in a GPT disk occupy those first two partitions.

To make sure rightclick on the small panel to the left of the drive map which says Disk0. Does it offer to convert to an MBR or a GPT disk. That will tell you which it is now.

If it's an MBR disk you should have wiped the GPT protective partitioning before repairing or installing. I would immediately back up my data to wipe the HD with Diskpart Clean Command then follow these steps to get a perfect Clean Reinstall - Factory OEM Windows 7.

If it's still a GPT disk then first you need to study and understand how these function with an EFI BIOS because it is new-generation and requires different steps for install as well as repair. You can confirm an EFI BIOS by looking for EFI Boot Disk in the BIOS setup boot order listings:
